Hello,
if i bind a RadGrid with a DataTable as DataSource. 
There are no columns in the RadGrid only the DataSource had some.
Displaying the data works.
I have to let the user group the columns. It don't work if there are none.
GridColumnGroup colGrp = new GridColumnGroup();            colGrp.Name = TextBox1.Text;            colGrp.HeaderText = TextBox1.Text;                         RadGrid1.MasterTableView.ColumnGroups.Add(colGrp);                         RadGrid1.MasterTableView.Columns[0].ColumnGroupName = TextBox1.Text;            RadGrid1.MasterTableView.Columns[1].ColumnGroupName = TextBox1.Text;
Please take a look at the added pictures.

I have an odd issue with the display date being in the wrong culture. When simply adding the control on the HTML side, there is no problem.
However, in our situation, we have the datepicker embedded in a user control. The user control is then dynamically created on the fly when needed using the TemplateControl.LoadControl method.
I have read an older article in the UI for WPF forum that I can set the Culture to Null. However, I cannot seem to do this programatically on the ASP.NET side, as we are using UI for AJAX. Any help with this issue would be greatly appreciated.

I am facing an issue with close and rebind radwindow when i click button to close window and rebind radgrid in parent page.
it work on IE, chrome but it does not close and rebind data on safari.
RadWindow code behind
protected void Button1_Click(object sender, EventArgs e)
{
InjectScript.ClosePopup(this, "CloseAndRebind('navigateToInserted')");
}
InjectScript class
public static void ClosePopup(Page p, string jsFunc)
    {
        ScriptManager.RegisterStartupScript(p, p.GetType(), "CloseWindow", jsFunc, true);             
    }

I've got a custom Context Menu that is accessible from anywhere in my grids for setting gridlines (horizontal, vertical, both, none), or export to excel, which I've gotten to work very well.
I would also like to include the HeaderContextMenu (columns) only, so the users can customize the columns displayed. I've been completely unsuccessful in getting those to work as one item. In short, is there an easy way to add the columns like those shown in the HeaderContextMenu to my custom context menu and have it function like it does from the HeaderContext menu, with persisting the displayed columns after the users makes their column display choices.
As it is now, I have my custom context on the grid and the headercontext columns accessible from the header only.

I would like to fire a RadComboBox's SelectedIndexChanged event from another function in JS. For a standard dropdown list I would use "onchange()" but for the RadComboBox I get TypeError: RadComboBox1.onclick is not a function. Is there a way to fire a selectedindexchanged event from javascript on a radcombobox?
Example:
function fireSelectedIndexChanged() {    var comboBox = $find("<%=RadComboBox1.ClientID%>");    comboBox.onchange(); <---- fire selectedindexchanged event}
Hi,

When my MVC razor Kendo Grid is in:
GridEditMode.InCelland I click on "cancel changes"
or in:
GridEditMode.InLineand click on "cancel" Changes,
The lines are dropped from the grid..
Apparently this has to do with the fact that I load my grid on the client ajax call (generated by a treeview). It seems as if the grid is treating the lines as new because they were loaded at a later time then when the grid was created. 
What can I do to avoid this problematic behaivior? I have read many users have similar issues but no straightforward solution.
Here is my JavaScript:
01.function onSelect(e) {02.                    var node = e.node;03.                    var nodedata = $("#tvPH").data('kendoTreeView').dataItem(node);04.                    //Fill the Proc Equip Grid05.                    if (nodedata.nodeType == "pls") {06.                        $.ajax({07.                            //url: "/PlantHierArchy/GetProcEquip?plsID=" + nodedata.id,08.                            url: "/PlantHierArchy/ForeignKeyColumn_Read?plsID=" + nodedata.id,09.                            dataType: "json",10.                            cache: false,11.                            type: 'GET',12.                            success:13.                            function (result) {14.                                $("#lblPSU").text('Proc.

How do I get around this problem?
The ParentNodeId is NULL for 1-4
This constraint cannot be enabled as not all values have corresponding parent values.
