Hi -

I'm doing a trial of the the Telerik grid and want to know how to do the following;

Scenario
1. I databind the grid (on the server side) to a List<T> where T is a custom class.
2. This works fine. The grid displays the data.

If my grids page size is N, lets say 3 and my List<T> is > 3 items the grid does paging. But when I try to go to the second page nothing displays.      I'm guessing the Grid is expecting a method to populate the next set of data.

In my instance the number of items in List<T> is so small I want ALL of the List<T> to be bound to the grid on the server side call and the grid paging to work without a server call.   Is this possible?

  I've searched the documentation and can't find anything.

Thanks -

Rob

Thanks for the response Nikolay.

I'm not sure i'm stating what I want to do correctly...

Here is what I want
1. Enable paging on the grid
2. But I only want to bind the data one time. Say, the first time the page loads. I don't want each time the user pages to perform a server side request.

Here is some pseudo-code for what I want...

void page_load()
{
If (!this.IsPostBack)
{
    this.RadGrid.DataSource = List<T>;   //Where T is any type of custom class.
    this.RagDrid.DataBind();
   }
}

Then I want the grid to have paging, and when the user moves to the next page the data would already exist on the client and no server hit would occur.

It is like all of the data is serialized to the client during the page load and the client portion of the grid manages all the data.

Are you saying once pagng is enabled on the grid, the grid must have a server side method to call as each page is requested?

Thanks -

Rob

I have a similiar situation.
My radgrid(ajaxified) is databound using an asp button. Everytime the button is clicked a texbox value is read and used in the sqlquery parameter. I have enabled paging in the grid.
Here is my psuedocode:

Button_click()
{
    buildtable()
}

buildtable()
{
    radgrid.datasource = mydataview
    radgrid.databind()
}
radgrid_pageindexchanged()
{
    buildtable()
}

My pagesize is 6. I want the user to be able to click next page to show 7-12 records. But this is not working.

thanks for any help.
