How to find all the checked checkboxes in an gridview

I have seen this question a gazillion times on the forums – Finding checked checkboxes in an ASP.NET GridView. Here’s how to do so. The CheckBox in our example is in a TemplateField as shown below:

ItemTemplate >
asp:CheckBox id="CheckBox1" runat="server" />

In order to find the checked checkboxes on a button click, use this simple code


    protected void Button1_Click(object sender, EventArgs e)
foreach (GridViewRow gvr in GridView1.Rows)
CheckBox chkBox = (CheckBox)gvr.FindControl("CheckBox1");
if (chkBox != null && chkBox.Checked)



Protected Sub Button1_Click(ByVal sender As Object, _
ByVal e As EventArgs)
For Each gvr As GridViewRow In GridView1.Rows
Dim chkBox As CheckBox = _
CType(gvr.FindControl("CheckBox1"), CheckBox)
If chkBox IsNot Nothing AndAlso chkBox.Checked Then
' Do Something
End If
Next gvr
End Sub
