I have a grid where I'm binding data in the needdatasource event, and I'm retrieving a limited selection of records based on the page index. So when they go to the next page, I want to get the next batch of records based on the page size, and when they go back I want to get the previous batch, etc.

The problem I'm seeing is that the NeedDataSource event fires BEFORE the PageIndexChanged event. This means the CurrentPageIndex of the data grid in the NeedDataSource will always be incorrect, since it will always have the old value. I tried testing the RebindReason of the grid to see if I could determine if a page event had caused it, but that always returns ExplicitRebind {4} so it is useless.

How do I figure out what the correct page index is in the NeedDataSource event?

 I am trying to export a telerik gridview to pdf. Although I have managed to do that, I would like to include inside the pdf text like title, or use some values from textboxes inside the aspx page.

I am not sure if the current version of telerik support these actions. Which version of telerik supports these actions and where can I find more information about this if I would like to have this functionality?

What is the code needed for this functionality? so that I can test it with my current version..
Thanks

Hi,

i need the code behind for deleting rows using Telerik gridview. Currently I have the following at the aspx page:
<telerik:GridClientDeleteColumn ConfirmText="Delete row" ButtonType="ImageButton">

what is the method called so that I construct the delete action ? now I am using only the code above - when i delete row disappears but If i do another action I get the error message invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@Page EnableEventValidation="true" %> in a page For security purposes, this feature....

I suspect that the problem is that because I havent inert any code in the code behind file .ascx
which method do I have to implement??

thanks!

Hi to all,
I'm facing an annoying problem with RadGrid OnInsertCommand + RadEditor, more specifically (following this demo on Telerik examples portal: http://demos.telerik.com/aspnet-ajax/editor/examples/edittemplate/defaultcs.aspx) I'm trying to handle the insert command from code behind and the problem is that I'm not able to get the 'Content' of the RadEditor after the Insert calls the code behind.

Some code will be more explicative:

.aspx (my RadGrid with RadEditor inside)

.aspx.cs

The problem is that when i hit the Insert and the debugger make me jump at 'Breakpoint1' my Content and Text are empty ("") instead of what I wrote before.  When I hit Update in Edit mode (obviously debugger jump on 'Breakpoint2') Content and Text have the right values from the DataSource.

I'm sure that I get the right RadEditor Control both in Insert that in Update because if I change the properties of one of that I can use the debugger to obtain evidence that I'm taking the right control.

I'm saying that is a strange issue because if you try providing Datasource directly in the .aspx, like in the Telerik Demo, all works perfectly.
I have tried many approaches found on the internet and in many forums but no one fits with my problem and I can't find a working example of handling the Insert command.
Am I missing something?

Thanks in advance
M
