problem reading the status of a check box in a gridview

Hello,

I have a GrideView that has 4 col. 3 of them are bound to a dataset and
the last one is not. The last one is check box. The check box is defined as
follow:



<asp:TemplateField HeaderText="Select">

<ItemTemplate>

<asp:CheckBox ID="chkSelect" runat="server" />

</ItemTemplate>

</asp:TemplateField>



I am trying to read the state of these checkbox using the folllwng code:



// Select the checkboxes from the GridView control

for (int i = 0; i < GridView_Enterprise_name.Rows.Count; i++)

{

GridViewRow row = GridView_Enterprise_name.Rows;

bool isChecked =
((CheckBox)row.FindControl("chkSelect")).Checked;

if (isChecked)

{

// do something

}

}



but the code doesn't work as isChecked is always false. What is the problem
and how can I solve it?



Regards

When do you do that? On the first page load or on postbacks? In what
event?

Is ViewState enabled for the gridview?

Make sure you are not re-loading the grid on every postback.

Thanks. The problem solved.
I set the datagride data source on page_load event and it seems that doing
this will reset the checkboxes. I used a ispostback and the problem solved
now.
