Hi Baba,

Now you want to capture the GridViewRow on which the CheckBox is selected on ButtonClick, right?

Try this.

<asp:GridViewID="Prescgrid"runat="server"AllowPaging="True"AllowSorting="True"

AutoGenerateColumns="False"BackColor="White"BorderColor="#3366CC"BorderStyle="None"

BorderWidth="1px"CellPadding="4"Height="49px">

<FooterStyleBackColor="#99CCCC"ForeColor="#003399"/>

<Columns>

<asp:TemplateFieldShowHeader="False">

<ItemTemplate>

<asp:LinkButtonID="LinkButton1"runat="server"CausesValidation="false"CommandName="Refill"

Text="Refill"></asp:LinkButton>

</ItemTemplate>

</asp:TemplateField>

<asp:TemplateFieldHeaderText="Patient_id"SortExpression="patient_id">

<EditItemTemplate>

<asp:TextBoxID="TextBox1"runat="server"Text='<%# Bind("patient_id") %>'></asp:TextBox>

</EditItemTemplate>

<HeaderStyleHorizontalAlign="Left"Wrap="False"/>

<ItemTemplate>

<asp:LabelID="Label1"runat="server"Text='<%# Bind("patient_id") %>'></asp:Label>

<asp:CheckBoxID="CheckBox2"runat="server"AutoPostBack="true"OnCheckedChanged="CheckBox2_CheckedChanged"/>

</ItemTemplate>

</asp:TemplateField>

<asp:BoundFieldDataField="prescription_date"DataFormatString="{0:d}"HeaderText="Prescription Date"

HtmlEncode="False"SortExpression="prescription_date">

<HeaderStyleHorizontalAlign="Left"Wrap="False"/>

</asp:BoundField>

<asp:BoundFieldDataField="home_phone"HeaderText="Patient Home Phone"SortExpression="home_phone">

protectedvoid CheckBox2_CheckedChanged(object sender,EventArgs e)

{

string cScript ="<script>alert('Another CheckBox already checked');</script>";

}

}

if (!blnFlag)

{

ClientScript.RegisterStartupScript(typeof(Page),"clientscript", cScript);
