RadComboBox in EditItemTemplate of RadGrid not Finding SelectedValue

[Lee]

Trying to get the selected value from the radcombobox that is in the edit item template of the radgrid.  Also trying to set the selected value when the edit command is selected.  here is the code below. In the update command i can find the control but for some reason the selected value is blank.  What about using the onSelectedIndexChanged?  is there a certain way you have to do it when the radcombobox is within the edit item template?

Thanks.

Hello Lee,

Since you using the ItemsRequested event , you have to set the selected value explicitly in the RagGrid ItemDataBound event. This is because the editform opens too early to bind the RadComboBox in EditItemTemplate.

Here is the code that i tried for a similar scenario.

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
    {
        if (e.Item.IsInEditMode)
        {
            GridEditableItem edititem = (GridEditableItem)e.Item;
            if ((e.Item is IGridInsertItem))
            {
                GridDataItem item = (GridDataItem)edititem.OwnerTableView.Items[0] ;
                DataRowView rowview = (DataRowView)item.DataItem;
                RadComboBox combo = (RadComboBox)edititem.FindControl("RadComboBox1");
                combo.Text = rowview ["JobCode"].ToString();
            }
        }
    }

And the following code will help you in accessing the RadComboBox SelectedValue in UpdateCommand.

Code:

Protected Sub RadGrid1_UpdateCommand(source As Object, e As GridCommandEventArgs)
    Dim editedItem1 As GridEditableItem = TryCast(e.Item, GridEditableItem)
    Dim combo As RadComboBox = DirectCast(editedItem1.FindControl("RadComboBox1"), RadComboBox)
    Dim selected As String = combo.SelectedValue

End Sub

Thanks,
Princy.

Dim item As GridDataItem = DirectCast(edititem.OwnerTableView.Items(0), GridDataItem)

doesn't get the value of the item...

[Lee]

this worked for the selectedvalue set

Dim value As String = edititem.OwnerTableView.DataKeyValues(e.Item.ItemIndex)("JobId").ToString()
Dim combo As RadComboBox = DirectCast(edititem.FindControl("RadComboBox1"), RadComboBox)
combo.Text = value

sorry that only gets the keyvalue...still working.

Dim value As String = edititem.OwnerTableView.DataKeyValues(e.Item.ItemIndex)("JobId").ToString()

                Dim combo As RadComboBox = DirectCast(edititem.FindControl("RadComboBox1"), RadComboBox)

                combo.Text = valu

[Lee]

didn't realize i could use DataKeyNames="JobId,JobCodeMatch" 

that with e.Item.OwnerTableView.DataKeyValues(e.Item.ItemIndex)("JobCodeMatch").ToString

set the selected value.

thanks!

Protected Sub RadGrid1_UpdateCommand(source As Object, e As GridCommandEventArgs)

    Dim editedItem1 As GridEditableItem = TryCast(e.Item, GridEditableItem)

    Dim combo As RadComboBox = DirectCast(editedItem1.FindControl("RadComboBox1"), RadComboBox)

    Dim selected As String = combo.SelectedValue

End Sub

says that that selectedvalue on the update is empty.

so not sure why this is happening.

Hi Lee Wilbourn,

Your case is complex and finding the root cause of the empty selected value would require thorough testing/debugging. Please open a support ticket and send us a working project that shows the issue. We will do our best to find the cause of the error and will write to you and in this forum thread as well.

All the best,
Simon
