Hello Shankar,

You can try the following code snippet to get the ClientSelectColumn value in Button Click event.

ASPX:

 <telerik:GridClientSelectColumn UniqueName="ClientSelectColumn">
 </telerik:GridClientSelectColumn>

C#:

 protected void Button1_Click(object sender, EventArgs e)
    {
        foreach (GridDataItem item in RadGrid1.MasterTableView.Items)
        {
            CheckBox chk = (CheckBox)item["ClientSelectColumn"].Controls[0];
            if (chk.Checked)
            {
                // your code
            }
         }
     }

Regards,
Shinu.

Hi shinu,

I am also facing the same issues , and i worked with your provided solution it doesn't work for me ,

foreach (GridDataItem item in RadGrid1.MasterTableView.Items)

{

CheckBox chk = (CheckBox)item["ClientSelectColumn"].Controls[0];

if (chk.Checked)

{

// your code

}

}

it only works for last page of rad grid .. then i changed code this way ....

 _grdDataListView.MasterTableView.AllowPaging = false;
            _grdDataListView.Rebind();
            int aas = _grdDataListView.Items.Count;
            foreach (GridDataItem item in _grdDataListView.MasterTableView.Items)
            {

              CheckBox _chkBox = (CheckBox)item["ClientSelectColumn"].Controls[0];
                if (_chkBox.Checked == true)
                {
                    _temp.Add(Convert.ToInt32(item.GetDataKeyValue(this.DataKeyNames[0].ToString())));
                }
                //String str = item["ColumnUniqueName"].Text;
            
            }
            _grdDataListView.MasterTableView.AllowPaging = true;
            _grdDataListView.Rebind();

i also try ,but my check box state is not getting after the rebind .. please provide any example or link .

Thank You .

Hi,

I am not sure about your requirement. Please take a look into the following code snippet I tried to persist the Check state of the ClientSelectColumn.

C#:

protected void Button1_Click(object sender, EventArgs e)
{
        _grdDataListView.AllowPaging = false;
        _grdDataListView.Rebind();
        foreach (GridDataItem item in _grdDataListView.Items)
        {
            CheckBox chk = (CheckBox)item["ClientSelectColumn"].Controls[0];
            if (chk.Checked)
            {

                //your code

            }
            _grdDataListView.AllowPaging = true;
            _grdDataListView.Rebind();
            ArrayList selectedItems;
            if (Session["selectedItems"] == null)
            {
                selectedItems = new ArrayList();
            }
            else
            {
                selectedItems = (ArrayList)Session["selectedItems"];
            }

            foreach (GridDataItem dataItem in _grdDataListView.Items)
            {
                string productID = dataItem.OwnerTableView.DataKeyValues[dataItem.ItemIndex]["DatakeyName"].ToString();
                selectedItems.Add(productID);
                Session["selectedItems"] = selectedItems;
            }
        }
}
protected void _grdDataListView_PreRender(object sender, EventArgs e)
{
        if (Session["selectedItems"] != null)
        {
            ArrayList selectedItems = (ArrayList)Session["selectedItems"];
            Int16 stackIndex;
            for (stackIndex = 0; stackIndex <= selectedItems.Count - 1; stackIndex++)
            {
                string curItem = selectedItems[stackIndex].ToString();
                foreach (GridItem item in _grdDataListView.MasterTableView.Items)
                {
                    if (item is GridDataItem)
                    {
                        GridDataItem dataItem = (GridDataItem)item;
                        if (curItem.Equals(dataItem.OwnerTableView.DataKeyValues[dataItem.ItemIndex]["DatakeyName"].ToString()))
                        {
                            dataItem.Selected = true;
                            break;
                        }
                    }
                }
            }
        }
}

Thanks,
Shinu.
