I have a simple gridview
<asp:GridView ID="GridView1" runat="server" DataKeyNames="OriginatorID" AutoGenerateColumns="False"
AllowPaging="True" OnPageIndexChanging="GridView1_PageIndexChanging" PageSize="5"
OnPreRender="GridView1_PreRender">
<Columns>
<asp:TemplateField>
<ItemTemplate>
<asp:CheckBox ID="CheckBox1" runat="server" />
</ItemTemplate>
</asp:TemplateField>
<asp:BoundField DataField="Originator" HeaderText="Originator" />
</Columns>
</asp:GridView>
I'm calling following code inside GridView1_PageIndexChanging
event
foreach (GridViewRow item in GridView1.Rows)
{
try
{
if (item.RowType == DataControlRowType.DataRow)
{
CheckBox chk = (CheckBox)(item.Cells[0].FindControl("CheckBox1"));
// chk.checked will access the checkbox state on button click event
if (chk.Checked)
{
//code if checked
}
else
{
}
}
}
catch (Exception ex)
{
throw ex;
}
}
problem if I select a checkbox and select the next page on gridview it never execute the code inside
if (chk.Checked)
even though I have checked the chekBoxes it's not get their state as checked.
why could this happen?

Try this:
Check Wheather you have put your code for binding data to GridView in
If (!IsPostBack)
{
//Code for Binding Data to GridView
}

my fault.i haven't done the following
if (!Page.IsPostBack)
{
Binddata();//Bind data to gridview
}
previously Binddata() method was not inside
if (!Page.IsPostBack)
which was causing the issue
