Any theme that I try to apply during runtime only results to the default theme being applied.

I tried ThemeResolutionService.ApplyThemeToControlTree(this, "ThemeName") it didn't work.

How to assign dynamicly a tooltip to a cell

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;

e.Row.Cells[e.ColumnIndex].CellElement.ToolTipText = errorMsg;

e.Row.InvalidateRow();

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?

Generate multiple images from chart view

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

hierarchical data. BestFit, possible?

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 :)
