You can use this code -

C#

protected void btnStartTrans_Click(object sender, EventArgs e)
{
    // Loop through all rows in the grid
    foreach (GridViewRow row in grid.Rows)
    {
        // Only look for `lbClose` in data rows, ignore header and footer rows, etc.
        if (row.RowType == DataControlRowType.DataRow)
        {
            // Find the `lbClose` LinkButton control in the row
            LinkButton theLinkButton = (LinkButton)row.FindControl("lbClose");

            // Make sure control is not null
            if(theLinkButton != null)
            {
                // Enable the link button
                theLinkButton.Enabled = true;
            }
        }            
    }
}

you did not get my point i guess when i keep if(theLinkButton != null)
{
// Enable the link button
theLinkButton.Enabled = true;
} then each time when i click link button it is going into if block but it should go into if block only when i click that link button

clearly I am not understanding but something I guess.So the bellow is given

The html code bellow
<asp:TemplateField HeaderText="Enable">
<itemtemplate>
<asp:LinkButton ID="lbtn" runat="server" Text='<% #Bind("Cat") %>' CommandArgument='<% #Bind("Cat") %>' OnClick="btnStartTrans_Click" CommandName="btnenable">

protected void btnStartTrans_Click(object sender, EventArgs e)
{
LinkButton lbtn = (LinkButton)sender;
lbtn.Enabled = false;

}
