Hi,

I’m trying to bind a GridDropDownColumn dynamically to a RadGrid.

Each row in the RadGrid has an independent GridDropDownColumn and values in these dropdown is not the same in the rest of the rows.

Say, there a row ‘CountyCode’ and has a GridDropDownColumn with a set of CountryCodes.

And the next row may be States and the GridDropDownColumn will have the StatesList.

But when I identify the GridDropDownColumn with a UniqueName, all the dropdown vales in the Grid gets updated with the last set of values.

(Got an example from telerik.com to Customize/Configure GridDropDownColumn)

Please let me know how to identify a specific row in a RadGrid & just bind that GridDropDownColumn in that row.

Here is the code I’m working on.

protected void RadGrid_ItemDataBound (object sender, Telerik.Web.UI.GridItemEventArgs e)

    {

        if (e.Item is GridEditableItem && (e.Item as GridEditableItem).IsInEditMode)

        {

            GridEditableItem editedItem = e.Item as GridEditableItem;

            GridEditManager editMan = editedItem.EditManager;

            int i = 0;

            foreach (CommonConfigurationDataItem cd in _configData)

            {

                try

                {

                    if (cd.Values != null && cd.Values.Count > 0)

                    {

                        GridDropDownColumnEditor editor = editMan.GetColumnEditor("List") as GridDropDownColumnEditor;

                        editor.DataSource = cd.Values;

                        editor.DataBind();

                    }

                  //’i’ would be a row index – How do I access the GridDropDownColumn in that row using i//

                }

                i++;

            }

        }

    }

private void AddComboBoxPDValues()

      {

        if (RadGrid.Columns.Contains("List"))

            RadGrid.Columns.Remove("List");

        GridDropDownColumn List = new GridDropDownColumn();

        List.HeaderText = "Provisioned Values";

        List.ReadOnly = false;

        List.UniqueName = "List";

        RadGrid.Columns.Add(List);

      }

Thanks!

Also, when viewing the List Form within SharePoint Designer, the field control does not render and gives the error:
"Failed to render "Description" column because of an error in the "Multiple lines of text" field type control. See details in log. Exception message: the RadControls folder was not found."

Thanks!
