I have run into this issue as well and have been using the following workaround.
Using the following settings:
AllowCustomEntry=true
InputType=Text
TextSettings-SelectionMode=Single
Withing the DropDownItemTemplate I put a javascript onclick event that calls a method to populate hidden fields.
ASPX:
1.<DropDownItemTemplate>2. <tableonclick="RadAutoCompleteBox_StoreData('<%# DataBinder.Eval(Container.DataItem, "RecordID")%>','<%# DataBinder.Eval(Container.DataItem, "RecordText")%>');">3. <!-- DropDownItemTemplate Text -->4. </table>5.</DropDownItemTemplate>
Javascript:
functionRadAutoCompleteBox_StoreData(value, text) { varSelectedText = text; varSelectedValue = value; // populate the hidden fields based on the values sent from the list item $("#hf_SelectedText").val(SelectedText); // store the data text $("#hf_SelectedValue").val(SelectedValue); // store the data value $("#hf_ListItemFound").val("1"); // indicate a list item was found}functionRadAutoCompleteBox_TextChanged(sender, eventArgs) { // do a quick check to see if a list item was found if($("#hf_ListItemFound").val() == "1") { $("#hf_ListItemFound").val("0"); // reset the list item found } else{ // populate the hidden fields based on the text entered $("#hf_SelectedText").val(eventArgs.get_text()); // use the textbox value $("#hf_SelectedValue").val("0"); // set a default value $("#hf_ListItemFound").val("0"); // reset the list item found }}
When the form is submitted, I just pulled the needed data from the hidden field. I populated the Text in a hidden field to keep it transparent. Typically, I just pull the text from the RadAutoCompleteBox.Text.
