checkbox client row selection values on server side

[cognos s]

I have a radgrid and I would like to provide checkboxes in first column for each record. If I use 
<telerik:GridClientSelectColumn UniqueName="ClientSelectColumn" />

how can I get the checkbox selection on server side so that I know which record to update. the user can do multiple selections. pls provide me an example.

I believe this article, which explains how to keep selected rows through postback, should provide you with an example of how to interact with selected items. Using the same basic logic here you should be able to do whatever it is you want to do. There are also a few other articles in the documentation that might help you with your implementation, I recommend you check them out :D

Hi,

You can traverse the selected items collection in a button click as shown below:
C#

protected void Button1_Click(object sender, EventArgs e)
    {
        foreach(GridDataItem item in RadGrid1.SelectedItems)
        {
            Response.Write(item["CustomerID"].Text.ToString() + "<br/>");
            string custID = item.GetDataKeyValue("CustomerID").ToString();
        }
    }

Thanks,
Shinu

grd.selecteditems.count is 0 on the server side. I can approach this in a different manner.

Yes, I found this also -SelectedItems in nothing , but row is checked. Please give me working code for this -its urgent:)

Hi,

How are you binding your grid ?.Could you post your code here.  At times the selected item count will not return anything if the grid is not  properly bound or you are making excess calls to Rebind.

Thanks,

Princy

grdList.DataSource = objBO.ExecQueryText("SELECT * FROM [Pages]").Tables(0)

grdList.Rebind() - in Page_Load and now I consider to use client-side js + hidden field, but prefer direct server side selecteditems use

Hello Dimo,

When you invoke the Rebind() method of the grid explicitly, the selected items (and their indices respectively) will be cleared. Hence consider modifying your grid binding to utilize NeedDataSource event handling as illustrated on this online demo of the product:

http://demos.telerik.com/aspnet-ajax/grid/examples/programming/needdatasource/defaultvb.aspx

Thus the grid will be rebound internally on sorting, paging, etc. operation and the selected items state will be retained.

Kind regards,
Sebastian
