Add an event in Gridview :

OnRowCommand="grdAccidentMaster_OnRowCommand"

Change template for button :

    <ItemTemplate>
       <asp:Button runat="server" Text="Click" ID="btnClick" 
      CommandName="SendIncidentNo"  CommandArgument='<%# Eval("IncidentNo") %>' />                    
    </ItemTemplate>

Code behind :

protected void grdAccidentMaster_OnRowCommand(object sender, GridViewCommandEventArgs e)
{
    if (e.CommandName != "SendIncidentNo") return;
    int incidentNo = Convert.ToInt32(e.CommandArgument);
    // do something
}
