Loop through radgrid

[Germaine]

I have a radgrid and I need to loop through (when the user hits a button) and check if the checkbox(es) has been selected and then get the ID to save into a variable.

<telerik:RadGrid ID="RadGrid1" runat="server" AllowFilteringByColumn="True" AllowSorting="True"
                    CellSpacing="0" GridLines="None" AutoGenerateColumns="False"
                    AllowMultiRowSelection="True" AllowPaging="True" PageSize="20" >
                    <GroupingSettings CaseSensitive="false" />
                    <MasterTableView ShowFooter="false" DataKeyNames="ID" AllowFilteringByColumn="True" >
                        <Columns>
                            <telerik:GridClientSelectColumn UniqueName="chbxSelection" />
                            <telerik:GridBoundColumn UniqueName="FirstName" SortExpression="First_x0020_Name" HeaderText="First Name"
                                DataField="First_x0020_Name" AutoPostBackOnFilter="true" CurrentFilterFunction="Contains" AllowFiltering="true">
                            </telerik:GridBoundColumn>
                            <telerik:GridBoundColumn UniqueName="LastName" SortExpression="Last_x0020_Name" HeaderText="Last Name"
                                DataField="Last_x0020_Name" AutoPostBackOnFilter="true" CurrentFilterFunction="Contains" AllowFiltering="true">
                            </telerik:GridBoundColumn>
                             <telerik:GridBoundColumn UniqueName="Organization" SortExpression="Organization" HeaderText="Organization"
                                DataField="Organization" AutoPostBackOnFilter="true" CurrentFilterFunction="Contains" AllowFiltering="true">
                            </telerik:GridBoundColumn>
                             <telerik:GridBoundColumn UniqueName="Title" SortExpression="Title" HeaderText="Title"
                                DataField="Title" AutoPostBackOnFilter="true" CurrentFilterFunction="Contains" AllowFiltering="true">
                            </telerik:GridBoundColumn>
                            <telerik:GridBoundColumn UniqueName="ID" Visible="false" DataField="ID" AutoPostBackOnFilter="true" CurrentFilterFunction="Contains">
                            </telerik:GridBoundColumn>
                        </Columns>
                    </MasterTableView>
                    <ClientSettings>
                        <Selecting AllowRowSelect="true" />
                    </ClientSettings>
                </telerik:RadGrid>

Hello Germaine,

Try the following code snippet to achieve your scenario.
C#:

protected void Button1_Click(object sender, EventArgs e)
    {
        int count = 0;
        foreach (GridDataItem item in RadGrid1.MasterTableView.Items)
        {
            CheckBox chk = (CheckBox)item["chbxSelection"].Controls[0];
            if (chk.Checked)
            {
                count++;
            }
        }
        Response.Write(count);
    }

Thanks,
Shinu.

That code did not work.  It said the checkbox was not checked (false) even when all were checked.  Do you have any other suggestions or code snippets?

Hello Germaine,

The code worked as expected at my end and it returns the exact count of the checked items. If the problem still persist I suggest you to try to use Template column with asp:CheckBox for selection.

Grid / Server-side Row Selection.

Hope this might solves the issue.

Thanks,
Shinu.
