Web User Control Components Self Resetting

[Stevan Gajic]

I've got a RadGrid inside a RadMultiPageView all inside a RadAjaxPanel, for editing the grid I used a WUC which contains various RadComboBoxes and RadTextBoxes including Numerics. My problem is that on postback, the server side code executes, but the value selected isn't used. Instead the original value is being executed. I've tried removing all the behaviors from the code execept those that actually build the component with the same results. The grid uses an ODS for the data source. The dropdown boxes are built procedurally on page load.

The grid declaration:

                <telerik:RadGrid ID="rgBacteriaWarning" runat="server" ondetailtabledatabind="rgGrid_DetailTableDataBind" onitemupdated="rgBacteria_ItemUpdated">
                </telerik:RadGrid>

Code that builds the grid:

                ObjectDataSource ods = new ObjectDataSource();
                ods.SelectMethod = "GetHoldingTests";
                ods.SelectParameters.Add("guid", guid.ToString());
                ods.SelectParameters.Add("type", Enum.GetName(typeof(ValidationType), ValidationType.Warning));
                ods.TypeName = "CTI.CTCM.Data.Samples.BacteriaODS";

                rgBacteriaWarning.Columns.Clear();
                rgBacteriaWarning.Skin = SKINNAME;
                rgBacteriaWarning.AllowAutomaticDeletes = true;
                rgBacteriaWarning.AllowAutomaticUpdates = true;
                rgBacteriaWarning.AllowPaging = true;
                rgBacteriaWarning.AllowSorting = true;
                rgBacteriaWarning.AutoGenerateColumns = false;
                rgBacteriaWarning.DataSource = ods.Select();
                rgBacteriaWarning.MasterTableView.EditFormSettings.EditFormType = GridEditFormType.WebUserControl;
                rgBacteriaWarning.MasterTableView.EditFormSettings.UserControlName = "VerifyBacteria.ascx";
                rgBacteriaWarning.MasterTableView.EditMode = GridEditMode.EditForms;

                rgBacteriaWarning.Columns.Add(new GridEditCommandColumn());
                rgBacteriaWarning.Columns.Add(gb1);
                rgBacteriaWarning.Columns.Add(gb2);
                rgBacteriaWarning.Columns.Add(gb3);
                rgBacteriaWarning.Columns.Add(gb4);
                rgBacteriaWarning.Columns.Add(gb5);
                rgBacteriaWarning.Columns.Add(gb6);
                rgBacteriaWarning.Columns.Add(gb7);
                rgBacteriaWarning.Columns.Add(gb8);
                rgBacteriaWarning.Columns.Add(gb9);
                rgBacteriaWarning.Columns.Add(gb10);
                rgBacteriaWarning.Columns.Add(gb11);
                rgBacteriaWarning.Columns.Add(gb12);
                rgBacteriaWarning.Columns.Add(gb13);
                rgBacteriaWarning.Columns.Add(gb14);
                rgBacteriaWarning.Columns.Add(gb15);
                rgBacteriaWarning.Columns.Add(gb16);

                if (rgBacteriaWarning.MasterTableView.DetailTables.Count < 1)
                {
                    GridTableView gtvWarning = new GridTableView(rgBacteriaWarning);
                    rgBacteriaWarning.MasterTableView.DetailTables.Add(gtvWarning);
                    gtvWarning.DataMember = "warningDetails";
                }

                rgBacteriaWarning.DataBind();

Hi Stevan,

I suggest that you handle the DataBinding event of the user control and there bind the comboboxes and set their selected values. Find the below article for more information:
