I'm trying to add 40 rows in a grid programmaticly like this :


when adding let say 30 rows (nb=30) the grid is extremely slow. Is there something i should do to fasten things up?

I've tried using 

grdSearchResults.GridElement.BeginUpdate();

instead of SuspendUpdate but the grid throws an argument out of range exception stating that Value is out of range???

Hi All, 

I have Telerik grid view that has a view definition, and i need to export it to excel sheet, i succeeded to export the grid to excel sheet but it was exported without its View Definition. 

Is there any way to export Telerik grid with its view definition to excel file ??

Thanks In Advance :) 

I am using the RadMaskedTextBox for a phone number input.  For my situation, when a different country is selected, I am dynamically creating the mask to include the country code.  The behavior I would prefer would be that when the user starts to input numbers, the country code would be ignored.  This works great if the user starts with a number different then the country code.  But, if the user starts with the same number as the country code, the carat only moves through the mask.

To illustrate further.  If the mask is this:  +56 _____________  , and I start typing a phone number that doesn't start with 5, such as 345, the box will look like this : +56 345_______  .   This is fine, and what I would expect.

If, however, I would start typing and the input starts with 5, such as 595, the box will look like this:  +56 95____________ .

This is because the first 5 is being "eaten up" by the mask.   Is there an easy way to disable the mask from "eating up" this input?

Thank you!

I want to change backcolour of the radgrid while printing the panel which contains this particular grid.
On click of print button , the grid backcolour should be none in the page being printed.

I want my users to be able to see that there is a spot to enter the criteria for the filter without having to know to click on the empty space and a box will appear. Is there a simple way to show those boxes to the users even when they do not have focus?

I fill this dropdown list in this way


Now I need to add at index 0 something like "Select a table..."

How do I do that?
I have tried something like this but I need to add it at index 0.

I am using this line of code to allow the user to choose the page size:


It works fine until the textbook is empty. In such case the amount of rows get stacked to 1 and there is no more control. I mean, paging size does not work anymore. Is this an expected behavior? 
I solved it like this:


Thanks
