Updating event title dynamically

November 29, 2016, 3:07 am
$
0
0
Hello Laurence,

Thank you for the last clarification. Please note that the Scheduler "moveend" and "save" events receive the currently edited event as parameter. That why the "save" event can be modified as follows:

save: function(e) {
      e.event.set("title", "UPDATED TITLE");
},

Also you can skip using the "moveend" event if you always update the title in the "save" event.

Hi,

I would like to know if it's possible to do the following thing with the SearchBox:

I want to ignore certain words like in this case:

the user types "courses in technology" and I want to ignore the words "courses in" so only the word "technology" would be searched

in the datasource. is it possible to do this thing ?

UserControl on Tooltip when hover a gridcell

Hi Martin, thank you for your reply

I have followed your tip and got my tooltip showing preloaded data.

but I need to modify this solution in order to show data on demand. that is on mouse hovering of that cell

here is what I came up with:

<telerik:GridViewDataColumn   Width="50*"
                            DataMemberBinding="{Binding UserCount}"IsFilterable="False">
    <telerik:GridViewDataColumn.CellTemplate>
        <DataTemplate>
            <TextBlockText="{Binding UserCount}"MouseEnter="TextBlock_MouseEnter"/>
        </DataTemplate>
    </telerik:GridViewDataColumn.CellTemplate>
    <telerik:GridViewColumn.ToolTipTemplate>
        <DataTemplate>
            <StackPanelOrientation="Horizontal">
                <ListBoxItemsSource="{Binding UserNames}"/>
            </StackPanel>
        </DataTemplate>
    </telerik:GridViewColumn.ToolTipTemplate>
</telerik:GridViewDataColumn>

 

and the mouseenter event will trigger a Load method on the viewmodel to update the UserNames property there (a list of string)

but it won't work. the list comes empty. Is there something we can do about it?

 

Thanks

Hello Stefan
Thanks for your answer, it partially works but I still have a little trouble like you have with your project.

RadMenu not closing anymore

Hello,

You may overcome this issue by wrapping the sender.close() line in a setTimeout() function with a slight delay:

setTimeout(function () { sender.close(); }, 10);

Thus, the menu item will close again in all browsers.

More row details and dataform questions

November 29, 2016, 3:07 am

Hi,
below is a stripped down version of my rowdetail editor using a raddataform with a rowdetails template.
I tried adding CommandButtonsVisibility="All" but it did nothing. I want to show add, delete, edit etc. I'm only getting the edit button.

Some more issues.

1. The OK and Cancel Buttons are not picking up the global button style I have set in app.xaml.

2. Is it possible to have the OK button fire the RowEditEnded event?

3. The cancel button does not cancel the changes made in the dataform. Changes made to the form are immediately reflected in the
     RadGridView. I would have expected the cancel button to set things back to their original values. Am I missing something?

4. How do I get the radform to default to edit mode so that the user does not have to hit the edit button in the upper right corner first?

I've attached a screen shot.

Any help would be GREATLY appreciated.

Thanks ... Ed

RowDetails questions

November 29, 2016, 3:07 am

Hello Ed,

When you're editing the item through RadDataForm, you will need to handle its EditEnded event rather than RadGridView's RowEditEnded event which will not get fired as, technically, you're not editing the row, you're editing the bound data item. Please let me know if this would work for you.

RadGridView Asynch Loading

November 29, 2016, 3:07 am
$

Hi,

So when using an application like SQL Server Management Studio I can run a query (let's say select * from customer although my queries are very user driven with a few joins mostly the SQL is generated dynamically) and the results grid will start populating rows extremely quickly until the full set is returned.

I want to emulate this behavior using a RadGridView (WPF)

I have tried using a data set it takes to long and you don't get that initial feedback of seeing the first rows start flooding in.

Next I tried loading the customers from a data reader and putting each row into an ObservableCollection<Customer> it is way faster and allows the objects in .Net to start being populated even before the query has finished but ultimately the UI was unable to keep up with the reader and froze until the full set was populated.

What would be the best approach to get that fast response of data loading and the user seeing the rows start to appear without locking down the UI Thread of the application?

A typical result set is around 100k records and I can put it in the grid in about 5 seconds using a dataset im hoping to get similar time while showing the user immediate feedback their query is getting results

Hi Marcel,

This is not a known issue. Is it possible for you to provide a small Kendo Dojo example which demonstrates the issue so I can examine your exact scenario and assist you further?

If I understood correctly the problem will not occur if the ToolBar has resizable set to false, is that correctly?

Looking forward to your reply.

Prevent users manually entering date via input control

Hi Michael,

Generally, you can achieve this requirement using the Edit event handler:
http://docs.telerik.com/kendo-ui/api/javascript/ui/grid#events-edit

When the row or cell is opened in edit mode, you can find the instance of the picker. Here is a common sample:
Copy Code
.Events(events => events.Edit("onEdit"))
JavaScript:
Copy Code
function onEdit(args) {
    if (args.model.isNew() != false) {
            // textbox
            $("#ShipName").attr("readonly", true);
             
            // dropdownlist
            var kendoDdl = $("#ShipCountry").data("kendoDropDownList");
            kendoDdl.readonly(true);
    }
}

Once you have the picker instance, you can find its input element and attach event to its key press and if the key is for example Esc or Backspace, you can clear the picker content. Alternatively, you can manually create a X clear button next to the picker ​to do that.

Eyup

RadScheduleView TimeRuler command

November 30, 2016, 4:22 am

Hi,

I use the RadScheduleView and I try to add an command to the TimeRuler line (on each date). I implement custom TimeRulerItemTemplateSelector like this : 

TimeRulerItemTemplateSelector="{StaticResource CustomTimeRulerItemTemplateSelector}"

 

In this template, I use the HorizontalTimelineGroupTemplate with an TextBlock to format the text. This works great. I want to add an command to this TextBlock (or a button), but the command is never raised.

I have try with the InputBinding :

<selectors:CustomTimeRulerItemTemplateSelector.HorizontalTimelineGroupTemplate>
    <DataTemplate>
        <TextBlock  TextAlignment="Left"Padding="2,0">
            <TextBlock.Text>
                <MultiBindingConverter="{StaticResource DateToStringFormatConverter}">
                    <BindingPath="DateTime"/>
                    <BindingPath="DataContext.PlanningHelper.GroupHeaderStringFormat"RelativeSource="{RelativeSource AncestorType={x:Type ucPlanning1:PlanningList}}"/>
                </MultiBinding>
            </TextBlock.Text>
            <TextBlock.InputBindings>
                <MouseBindingCommand="{Binding DataContext.TestCommand, RelativeSource={RelativeSource AncestorType={x:Type ucPlanning1:PlanningList}}}"MouseAction="LeftClick"/>
            </TextBlock.InputBindings>
        </TextBlock>
    </DataTemplate>
</selectors:CustomTimeRulerItemTemplateSelector.HorizontalTimelineGroupTemplate>

 

And with telerik:EventToCommandBehavior.EventBindings :

<selectors:CustomTimeRulerItemTemplateSelector.HorizontalTimelineGroupTemplate>
    <DataTemplate>
        <TextBlock  TextAlignment="Left"Padding="2,0">
            <TextBlock.Text>
                <MultiBindingConverter="{StaticResource DateToStringFormatConverter}">
                    <BindingPath="DateTime"/>
                    <BindingPath="DataContext.PlanningHelper.GroupHeaderStringFormat"RelativeSource="{RelativeSource AncestorType={x:Type ucPlanning1:PlanningList}}"/>
                </MultiBinding>
            </TextBlock.Text>
            <telerik:EventToCommandBehavior.EventBindings>
                <telerik:EventBindingCommand="{Binding DataContext.TestCommand, RelativeSource={RelativeSource AncestorType={x:Type ucPlanning1:PlanningList}}}"EventName="MouseEnter"/>
            </telerik:EventToCommandBehavior.EventBindings>
        </TextBlock>
    </DataTemplate>
</selectors:CustomTimeRulerItemTemplateSelector.HorizontalTimelineGroupTemplate>

 

But my TestCommand is never call.

What's wrong with my code? How to implement command inside the TimeRuler?

Thanks for your help.

Hello Greg,

We have already answered the support ticket you have submitted on the same topic. I will post here a quote of the answer here for the people that would review this thread. 

As suggested in the TreeView with remote hierarchical datasource forum thread you could use the expand eventto save the expanded node and then use it in the dataSource's transport.read.data option to send it as an additional parameter to the server.

If you have any questions, I would like to suggest you to continue the discussion in the support thread to avoid any duplication.

replacting GridViewDataColumn for GridViewComboBoxColumn

November 30, 2016, 4:22 am
$

Hi,

At the moment I'm facing an issue, I have a RadGridView which can show different tables with different definitions(not at the same time)
So AutoGenerateColumns is set to True.

now it can happen that some columns have an FK to another table.
Before I replaced those columns in the DataLoaded event but because of performance reasons I would like to do those replaces in the CurrentCellChanged event.

The problem when I do this is that the new GridViewComboBoxColumn misses the link to the actual datasource, and while reading the value for saving in the database, the value is DBNULL.

the gridview in de Xaml looks like this

<DataTemplatex:Key="AdminViewMainSectorTemplate">
        <GridMargin="10">
            <Grid>
                <telerik:RadBusyIndicatorx:Name="BusyIndicator"Grid.Row="2">
                    <telerik:RadGridViewx:Name="gridViewAdminData"
                                                     ItemsSource="{Binding DataRecords, Mode=TwoWay}"
                                         RowEditEnded="EditRecord"
                                         Deleted="deleteRecord"
                                         AddingNewDataItem="AddingNewDataItem"
                                         MinColumnWidth="100"
                                         ColumnWidth="*"
                                         NewRowPosition="Top"                                         
                                         AutoGeneratingColumn="AutoGeneratingColumn"
                                         DataLoading="LoadData"
                                         DataLoaded="DataLoaded"
                                         CurrentCellChanged="CurrentCellChanged"
                                         SelectionUnit="Cell"
                                         >
                        <!--DataLoading="LoadData"
                                         DataLoaded="DataLoaded"-->
                        <telerik:EventToCommandBehavior.EventBindings>
                            <telerik:EventBinding
                            Command="{Binding HandleAddingNewRecordToDevicesGridCommand}"
                            EventName="AddingNewDataItem"
                            PassEventArgsToCommand="True"/>
                        </telerik:EventToCommandBehavior.EventBindings>
                    </telerik:RadGridView>
                </telerik:RadBusyIndicator>
            </Grid>
        </Grid>
    </DataTemplate>

and my code behind looks like this:

privatevoidCurrentCellChanged(objectsender, GridViewCurrentCellChangedEventArgs e)
       {
           RadGridView rgv = (RadGridView)sender;
           GridViewCell cell = rgv.CurrentCell;
           if(cell != null&& typeof(GridViewDataColumn) == cell.Column.GetType())
           {
               Models.MyEntities db = newModels.MyEntities();
               stringtableName = Helpers.GlobalParameters.currenTableName;
               if(tableName =="batches")
               {
                   stringfieldname = cell.Column.UniqueName;
                   if(fieldname == "ProductieOrderId")
                   {
                       intindex = cell.Column.DisplayIndex;
                       GridViewComboBoxColumn cbb = newGridViewComboBoxColumn();
                       cbb.DataMemberBinding = newSystem.Windows.Data.Binding(fieldname);
                       //cbb.DataMemberBinding = cell.DataColumn.DataMemberBinding;
                       cbb.ItemsSource = db.productieorder.ToList();
                       cbb.SelectedValueMemberPath = fieldname;
                       cbb.DisplayMemberPath = "Id";
                       //cbb.Name = fieldname;
                       cbb.UniqueName = fieldname;
                       cbb.DisplayIndex = index;
                       rgv.Columns.Remove(cell.Column);
                       //rgv.Columns.Remove(cell.DataColumn);
                       rgv.Columns.Add(cbb);
 
                   }
               } elseif(tableName =="artikel")

where the Field "Id" is the related field on the related table
If I do this
cbb.SelectedValueMemberPath = "Id";

what I would say is logical, the shown value in the combobox stays empty.

does anyone know where to look to fix this issue?
