I used from the training book the delete command.  The problem that I am having is when I try to delete a record in the RadGrid, I get the following error:

Object referance not set to an instance of an object

The weird thing is I got it from the Telerik RadControls Ajax book and besides that I have no clue.  See attached code:

MasterTableView Width="100%" EditMode="InPlace"

telerik:GridDropDownColumn DropDownControlType="RadComboBox"

<telerik:RadComboBox ID="RadComboBox1" runat="server">

<Items>

<telerik:RadComboBoxItem Value="3" Text="Excellent" />

<telerik:RadComboBoxItem Value="2" Text="Good" />

<telerik:RadComboBoxItem Value="1" Text="Fair" />

<telerik:RadComboBoxItem Value="0" Text="Poor" />

<telerik:RadComboBoxItem Value="4" Text="N/A" />

</Items>

</telerik:RadComboBox>

Hi,

Hi,

I have a Repeater inside a FormView in my page.I am creating a RadComboBox control programmatically and adding it to the Repeater.

void DynamicFieldsRepeater_PreRender(object sender, EventArgs e)

repeater = (Repeater)sender;

comboBox = new RadComboBox();

"combo";

      comboBox.DataSourceID =

"ObjectDataSource2";

      comboBox.DataTextField =

"Name";

      comboBox.DataValueField =

"Id";

      repeater.Controls.Add(comboBox);

    //DropDownList d = new DropDownList();

    //d.ID = "dropdown";

    //d.DataSourceID =

"ObjectDataSource2";
    //d.DataTextField = "Name";
    //d.DataValueField = "Id";

   // repeater.Controls.Add(dropdown);

}

When I run the page I get this java script error:
'addEventListener' is null on not an object.

The thing is when I use DropDownList instead of RadComboBox,it works fine without error.
I am able to add RadDatePicker,RadTextBox,RadNumerticTextBox without the error, but not RadComboBox.
I am facing the same error when I use PlaceHolder instead of Repeater and try to add RadComboBox to to the placeholder programmatically.
Just to mention that I tried adding the controls in IntemCreated event of the repeater and the same error happend.

Thanks for your help.
