Getting all the GridDataItems

[Kathy]

I have a RadGrid with paging.  There are 45 pages with 10 items per page.  If I call RadGrid1.Items, I only get the 10 items on the first page.  I want to get all 450 items.  How would I go about doing this?  Thanks.

Hello Karty,

In order to access all GridDataItems ,disable the paging property. After accessing the data ,set the paging with desired size.Try the following code.

C#:

protected void RadGrid1_PreRender(object sender, EventArgs e)
{
       RadGrid1.AllowPaging = false;
        foreach (GridDataItem item in RadGrid1.Items)
        {
            //access the item
        }
        RadGrid1.AllowPaging = true;
        RadGrid1.PageSize = 3;
        RadGrid1.Rebind();
}

Thanks,
Princy.

Hi Rohan,

Try the following code snippet to achieve your scenario.

C#:

protected void RadGrid1_PreRender(object sender, EventArgs e)
{
    RadGrid1.AllowPaging = false;
    RadGrid1.Rebind();
    foreach (GridDataItem item in RadGrid1.Items)
    {
        //Your code
    }
    RadGrid1.AllowPaging = true;
    RadGrid1.PageSize = 3;
    RadGrid1.Rebind();
}

Hope this helps.

Regards,
Princy.

Hello Rohan,

You could save the selected items in a collection variable and use it when necessary:

or

I hope this will prove helpful.

All the best,

Hi Eyup,

Thanks for replay ,
I have done all this things to persistence the selected row . My Problem is different , when ever i select the selected row from page 1 to page number such 4 or 5 i can able to access only the last page of radgrid . To access all the page or radgrid i am using this code
RadGrid1.AllowPaging = false;

    RadGrid1.Rebind();

    foreach (GridDataItem item in RadGrid1.Items)

    {

        //Your code

    }

    RadGrid1.AllowPaging = true;

    RadGrid1.PageSize = 3;

    RadGrid1.Rebind();

but after the rebind i am not able to get selected row ...
is there any other  way to get all the row of radgrid please provide any code snap or document ....

Thank you once again for replay...

Hi Rohan,

I have created a sample RadGrid web site where I implemented preserving and accessing the selected items on filter command. Please check out the attached application and let me know about the result.
