Hi, I am encountering slowness or laggy when i schroll up and down when viewing different aircraft types in the gridview in my program.

I need help and suggestions on how to speed up and reduce this lag.

I have roughly more than 1,500 cells in view on the page at a time with about 10 rows (each row 1 aircraft/component type)

I have read these two articles below on cellFormatting and viewCellFormatting and have set the  e.Row.Cells(0).Tag = "UPDATED".

But the schrolling up and down is still lagging. Can anyone help me ? Thanks.

If e.ColumnIndex = 0 Then
            If e.Row.Cells(0).Tag <> "UPDATED" Then
            e.Row.Cells(0).Tag = "UPDATED"

End If

Hello-

Using the RichTextEditor and retrieving [ MyRichTextControl.GetContent("HTML") ] from it using any text at all, the "title" of that property contains "Untitled".

Here's the exact return value: <title>Untitled</title>

Is there a simple way to not include a "title" by default, or null/blank it out ?

Thanks in advance -B

In example for WPF (https://www.telerik.com/forums/support-for-google-maps) you have a really great article on how to integrate Google or similar xyz imagery providers into RadMap. Is it possible to put the same example here for WinForms (c# project)? Because after hours of internet surfing, I was unable to find any information on this.

Hi,

Is there anyway to force row/cell validation from outside the grid?
Is there anyway to force data back to the data-set before validation?

I have a gridview that displays fine in the app.

Cells with multiple values show up as:

Value 1

Value 2

Value 3

 

Within the cell.

But on exporting the grid the cells value is all on one row within the cell.

How to get the exported excel sheet to look like what is displayed on the apps grid.

This is what I am currently setting in code:

 objGrid.BestFitColumns();
spreadExporter = new Telerik.WinControls.Export.GridViewSpreadExport(objGrid)
                            {
                                ExportVisualSettings = true,
                                SheetName = strSheetName,
                                FileExportMode = Telerik.WinControls.Export.FileExportMode.NewSheetInExistingFile
                            };
exportRenderer = new Telerik.WinControls.Export.SpreadExportRenderer();

I have tried this in design time (Edit UI Elements >> RadDropDown TextBoxElement >> ShowClearButton).

But Nothing was happened.
