[Solved] Sorting on Column Formatted in RowFormatting

Hi All -

I have the following bit of code which works fine....I'm formatting a column based on the data in another column.

The problem I have arises when I try to sort on 'Display1' column by clicking the header. If I try to do when the grid is first populated, it doesn't sort. If I've scrolled thru the data once, then everything is fine.

I understand why this happens: Since the RowFormatting method is not called until the row in question is displayed, the 'Display1' values have not yet been populated in my non-visible rows.

So my question is this: What is the best way to get 'Display1' to sort properly? Do I simulate scrolling thru the grid to force RowFormatting to do its work? Or is there a better way?

Thanks as always,

Hugh

private void MasterTemplate_RowFormatting(object sender, RowFormattingEventArgs e)

{

if (e.RowElement.RowInfo.Cells["Data1"] != null)

{

if ((String)e.RowElement.RowInfo.Cells["Data1"].Value == "")

e.RowElement.RowInfo.Cells["Display1"].Value = "";

else

e.RowElement.RowInfo.Cells["Display1"].Value =

FormatData(e.RowElement.RowInfo.Cells["Data1"].Value);

}

grid view export to excel with groups

Hi I have a Rad Grid View that I am exporting to excel using the code below. This works fine, but I would like the code to export the grouped data so that excel sees it as grouped data rather than static cells. Is there a way to achieve this?

Thanks in advance.

private void button4_Click(object sender, EventArgs e)

{

ExportToExcelML exporter = new ExportToExcelML(this.radGridView1);

exporter.HiddenColumnOption = Telerik.WinControls.UI.Export.HiddenOption.DoNotExport;

exporter.ExportVisualSettings = true;

exporter.SheetName = "Films";

string fileName = "C:\\ExportedData.xls";

exporter.RunExport(fileName);

}

GridView exception

Hello, recently we began to encounter exceptions using Telerik GridView. Exception message:

System.NullReferenceException: Object reference not set to an instance of an object.
at System.Collections.Generic.Dictionary`2.Insert(TKey key, TValue value, Boolean add)
at Telerik.WinControls.Keyboard.ChordMessageFilter.CreateInstance()
at Telerik.WinControls.Keyboard.Shortcuts.AddShortcutsSupport()
at Telerik.WinControls.Keyboard.Shortcuts..ctor(Control owner)

at CreditAdmin.CardAdmin.Controls.Notifications..ctor() in c:\_Projects\CreditAdminTeboil\EmsAdmin\CreditAdmin\CardAdmin\Controls\Notifications.cs:line 17...

It seems like this happens only when we use ALT shortcuts (to navigate trough tabs ant some other functions). Does anyone knows what could be the cause of this problem ?

Expression Editor without the Gridview

I am trying to use your WinForms Expression Editor to validate a formula expression, directly into a Textbox. I do require a list of fields, but I do not need the gridview. Is there anyway to dynamically pass the list of fields and have the editor show without the GridView?
I have attempted with an invisible gridview, but this is rather ugly. Any hints?
Thanks!
