When I try to open a radwindow, the border is disappearing...If I use similar code on another page, it works just fine...

See attached image, here is the javascript code:

function ShowEditForm(id, boxid, rowIndex, authToken, apiKey) {

var grid = $find("<%= radgrid.ClientID %>");

        var rowControl = grid.get_masterTableView().get_dataItems()[rowIndex].get_element();
        grid.get_masterTableView().selectItem(rowControl, true);

var url = 'EditReportPage.aspx?id=' + id + '&boxid=' + boxid + '&authtoken=' + authToken + '&apikey=' + apiKey;

        var wnd = window.radopen(url, "EditReportDueDateData");
        wnd.setSize(550, 300);
        wnd.set_visibleStatusbar(false);
        wnd.center();
        return false;
}

4/13/2012 UPDATE:
This seems to be happening on IE9. I hit the page from IE8 and it seems to be working. With that being said, I have another page with a popup radwindow and it appears just fine using IE9. I am having this problem just on one page.

Thanks

Page cannot be null. Please ensure that this operation is being performed in the context of an ASP.NET request.

Hi,

I am creating a custom control in C#. this control will have a radcomboBox and lable in a html table. When you select an item in the radcomboBox, the selected item text will be diplayed in the lable. But when I try to render, I am getting error.

Page cannot be null. Please ensure that this operation is being performed in the context of an ASP.NET request.

RadComboBox

currencySelector = new RadComboBox();
currencySelector.ID = "dsfdsf";
//currencySelector.Items.Add(new Telerik.Web.UI.RadComboBoxItem("Australian"));
htmltableCell.Controls.Add(currencySelector);
htmlTableRow.Cells.Add(htmltableCell);
.....
currencyConverterTable.Rows.Add(htmlTableRow)
currencyConverterTable.RenderControl(output);

What am I doing wrong here???

Thanks,

Toby

[Solved] GridButtonColumn empty after click

Hi, i added a GridButtonColumn to my grid in the Page_Load event:

GridButtonColumn colEdit = new GridButtonColumn();
colEdit.UniqueName = "Edit";
colEdit.HeaderText = "Edit";
colEdit.Text = "Edit";
RadGrid1.MasterTableView.Columns.Add(colEdit);

When i click on it, i handle the RadGrid1_ItemCommand event:

protected void RadGrid1_ItemCommand(object sender, GridCommandEventArgs e)
{
if (e.CommandName == "Edit")
...
...
}

After the event the GridButtonColumn is empty, why?
Other problem is that the e.CommandName is alway empty, why?

Global Apply Filter Button

My grid binds to a huge set of data.
For performance reasons, we decided to request only visible elements from SQL server.
Therefore, we need to filter server side.

The filter icon has to be hidden so we are currently setting AutoPostBackOnFilter to true.
Clients are not happy with this solution because of the flickering.
They want to enter all their filter criteria in each column, then hit an Apply Filter button.

I have a screenshot showing what they want.
I tested many solutions, but none of them were satisfying. Is there an easy way to do it ?
