[Solved] RadComboBoxItem Add not working

[Josh]

I am tweaking the MyCustomFilteringColumn to filter a RadGrid.  The data is populating the
comboboxes just fine, however, I cannot seem to add an "All" item at the top of each
combobox.  Below is the code.  Thanks for any help provided.

	public class MyCustomFilteringColumnCS : GridBoundColumn
	{
	//RadGrid will call this method when it initializes the controls inside the filtering item cells
	protected override void SetupFilterControls(TableCell cell)
	{
	RadGrid RadGrid2 = (RadGrid)cell.Page.FindControl("RadGrid1");
	base.SetupFilterControls(cell);
	cell.Controls.RemoveAt(0);
	RadComboBox combo = new RadComboBox();
	combo.ID = ("ComboBox_" + this.UniqueName);
	combo.ShowToggleImage = false;
	combo.Skin = "Office2007";
	combo.AutoPostBack = true;
	combo.Items.Add(new RadComboBoxItem("All", "%"));
	combo.DataSource = RadGrid2.DataSource;
	combo.DataTextField = this.UniqueName;
	combo.DataValueField = this.UniqueName;
	combo.Items.Insert(0, new RadComboBoxItem("All","%"));
	combo.DataBind();
	combo.SelectedIndexChanged += this.list_SelectedIndexChanged;
	cell.Controls.AddAt(0, combo);
	cell.Controls.RemoveAt(1);
	}

Hello Josh,

Please try calling the DataBind method before inserting the 'All' Item.

combo.Items.Insert(0, new RadComboBoxItem("All","%"));
combo.DataBind();

->

combo.DataBind();
combo.Items.Insert(0, new RadComboBoxItem("All","%"));

All the best,
