In CellValidating i'm doing some validation on the values of the cell and depending if good or not i set e.cancel to true or not.
I would like to had a tooltip for that cell so the user would know what is wrong.
Here is what i'm doing
myObj obj = grdSearchResults.Rows[e.RowIndex].DataBoundItem as myObj;
if(obj==null)
return;
if (e.Value != null)
newValue = e.Value.ToString();
switch (grdSearchResults.Columns[e.ColumnIndex].UniqueName)
{
case "No":
if (!Validation.IsAlphaNumeric(newValue))
{
e.Cancel = true;
errorMsg = "Invalid No PNR. Must be alphaNumeric";
}
if (!e.Cancel && curPax.NoPNR != newValue)
modified = true;
break;
When a value is not entered correctly, i woul like to show that cell in red with a brief caption but it seem's impossible. Once a cell is cancelled, the client cannot do nothing before he corrects the entered value.
Any help?

Hello,
I started using Telerik just recently and this is my first post here.
I have RadChartView that gets populated with different LineSeries based on the selection I make in the Combobox. It works fine, and also I can Export single currently displayed images just fine. However, I need to export images for all combobox options at once by clicking on a single button. Currently I do this by manually switching combobox options from code and printing the charts which in the UI causes the chart to quickly switch from one to another.
My question is: is it possible to export all the charts to images without actually showing the switch visually? If not, any workaround is also welcome.
Thanks

Ive got 2 questions.
1)When I select a page of the grid, then in the OnCellValueNeeded event, if that page has no table of data then I call function "AskForData" which uses an event to run a sql query to read in 100 records to fill the table.
My call to Grid.VirtualGridElement.BestFitColumns(); is the last line of the AskForData() function as I didn't really know where else to put it, it seems to work. But at that moment of time, the cells haven't been formatted. Is there a recommended event I should trap?
2) I've set up my grid to use a hierarchical/child grid for displaying some data using the help document https://docs.telerik.com/devtools/winforms/virtualgrid/hierarchical-virtual-grid/hierarchical-data
Grid.VirtualGridElement.BestFitColumns seems to affect the masterviewinfo but not the child view info. Is there a way of accessing that to get bestfit on child columns?
thanks :)

I was wondering if it’s possible to get more advanced
formatting such as hollow (doughnut) points with an outline color (figure 1) or
even more advanced formatting like using gradient and bevel properties in Excel
(figure 2).

Hey guys, is it possible to create a List of GridViewDataColumn avaliable at design time? Like u do in the GridRelations(attached), I've tried reading your TemplateCollectionEditor(at Telerik.WinControls.UI.Design.dll, same namespace) class, but didn't understand anything.
Here is my class where I want' use it
public class ColunaTextoAjuda : IAjuda { public GridViewDataColumn Coluna { get; set; } [Browsable(true)] [DefaultValue("")] [Editor("Telerik.WinControls.UI.Design.TextOrHtmlSelector, Telerik.WinControls.UI.Design, Version=2018.1.116.40, Culture=neutral, PublicKeyToken=5bb2a467cbec794e", typeof(UITypeEditor))] public string Texto { get; set; } }8 answers

Hello All,
I have a requirement to print a number of RTF notes as a single document. I tried to create a RadDocument for each note and merge them, but unable to get it done.
Please guide me through the appropriate way to achieve this functionality.
