Get Client Side Checkbox Values in Code Behind

[Mike]

I am using the following in the RadGrid nested withing the MasterTable and Columns tags.

<telerik:GridClientSelectColumn UniqueName="ClientSelectColumn" />

I also have a button above my grid to submit the form/grid to the code behind and update the checked rows.  Right now I am unable to access the checked rows.

How do I get the values of the checked rows in the code behind using an asp:Button? 

<asp:Button ID="ButtonAssignUsers" CssClass="emabtn"  OnClick="ButtonAssign_Click" CausesValidation="false" Width="225px" Text="Assign Users &raquo;"
                                         runat="server" />

protected void ButtonAssign_Click(object sender, EventArgs e)
  {
    // What goes here so I can access the checked checkbox values?
  }

Hello Mike,

Check out the following code snippet to access the selected items in the grid.

CS:

protected void ButtonAssign_Click(object sender, EventArgs e)
    {
        foreach (GridDataItem item in RadGrid1.SelectedItems)
        {
            string strtxt = item["ColumnUniqueName"].Text;
        }
    }

Regards
Shinu.

When I put that code it I get "&nbsp:" as a  value?  Here is a snippet of the updated code, what is wrong here?

a  value? 

<MasterTableView DataKeyNames="ID" AllowMultiColumnSorting="True" Width="99%">
  <Columns>
         <telerik:GridClientSelectColumn UniqueName="ClientSelectColumn" />

  </Columns>
</MasterTableView>


Code Behind
protected void ButtonAssign_Click(object sender, EventArgs e)
    {
        foreach (GridDataItem item in RadGrid1.SelectedItems)
        {
            string strtxt = item["ClientSelectColumn"].Text;
        }
    }

Hi Mike,

You can access the CheckBox in the GridClientSelectColumn on clicking a button as shown below.

CS:

protected void ButtonAssign_Click(object sender, EventArgs e)
    {
        foreach (GridDataItem item in RadGrid1.MasterTableView.Items)
        {
            CheckBox chkbx = (CheckBox)item["ClientSelectColumn"].Controls[0];
            if (chkbx.Checked)
            {

            }
        }
    }

Thanks
Princy.

What would go inside the brackets to get the value of the checkboxed item?

Hi Mike,

Here is the code snippet I tried to access the cell text in a selected row on clicking a Button.

ASPX:

<Column>
     <telerik:GridBoundColumn DataField="FirstName"  HeaderText="FirstName" ReadOnly="True" UniqueName="FirstName">
        </telerik:GridBoundColumn>
    <telerik:GridClientSelectColumn HeaderText="SelectCol" UniqueName="SelectCol" ></telerik:GridClientSelectColumn>
  </Column>

CS:

protected void Button1_Click(object sender, EventArgs e)
    {
        foreach (GridDataItem item in RadGrid1.MasterTableView.Items)
        {
            CheckBox chkbx = (CheckBox)item["SelectCol"].Controls[0];
            if (chkbx.Checked)
            {

                string strtxt = item["FirstName"].Text.ToString();
            }
        }
    }

I was hoping to get the DataKeys!

This will do the job for me, but if you can show how to get the DataKey that would be fantastic!

Thank you!

Hi Mike,

Here is the code snippet to access the DataKeyName on clicking the button.

CS:

 protected void Button1_Click(object sender, EventArgs e)
    {
        foreach (GridDataItem item in RadGrid1.MasterTableView.Items)
        {
            CheckBox chkbx = (CheckBox)item["SelectCol"].Controls[0];
            if (chkbx.Checked)
            {

                string strKey = item.GetDataKeyValue("ProductName").ToString();
            }
        }
    }

Thanks
Princy.
