[Solved] Selecting RadComboBox value in GridTemplateColumn

[Ahrensberg]

Hi all,

I'm sure you understand my code beneath, but how could this be done better? Not really like this "selection-hack"...

GridTemplateColumn:

<telerik:GridTemplateColumn HeaderText="<%$ Resources:LanguageWeb, OrderLine_Paragraph %>"

UniqueName="ParagraphId" HeaderStyle-Width="200px">

<ItemTemplate>

<telerik:RadComboBox runat="server" ID="CbParagraph" OnInit="CbParagraph_Init" ToolTip='<%# Bind("Paragraph.id") %>' />

</ItemTemplate>

</telerik:GridTemplateColumn>

The combobox items is loaded in the OnInit event, and selection done in the ItemDataBound on the RadGrid like this:

protected void RadGrid_ItemDataBound(object sender, GridItemEventArgs e)
{
    if (!(e.Item is GridDataItem)) return;
    var gridItem = (GridDataItem)e.Item;

    var cbParagraphControl = gridItem.FindControl("CbParagraph");
    if (cbParagraphControl is RadComboBox)
    {
        var cbParagraph = (RadComboBox) cbParagraphControl;
        cbParagraphcbParagraph.SelectedValue = cbParagraph.ToolTip;
        cbParagraph.ToolTip = "";
    }
}

Any ideas?

Cheers, Ahrensberg

Hello,

I use the following code in order to access the RadComboBox which is placed in ItemTemplate of GridTemplateColumn.

C#:

    protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
    {
        if (e.Item is GridDataItem)
        {
            GridDataItem item = (GridDataItem)e.Item;
            RadComboBox combo = (RadComboBox)item.FindControl("CbParagraph");
            // Now set the combo SelectedValue
        }
    }

Hi Ahrensberg,

Try modifying the code as below and se if it makes any difference:

protected void RadGrid_ItemDataBound(object sender, GridItemEventArgs e)
{
    if (!(e.Item is GridDataItem)) return;
    var gridItem = (GridDataItem)e.Item;

    var cbParagraphControl = gridItem["ParagraphId"].FindControl("CbParagraph");
    if (cbParagraphControl is RadComboBox)
    {
        var cbParagraph = (RadComboBox) cbParagraphControl;
        cbParagraphcbParagraph.SelectedValue = cbParagraph.ToolTip;
        cbParagraph.ToolTip = "";
    }
}
