Reload a Gridview onclientclick

I have a gridview that is only shown in a modal popup. right before I call the modal popup I set a value in a textbox. The gridview inside the modal popup depends on that textbox's value for it's data to show up at all. SO onclick I want to reload the gridview so that it will reload with the textbox's value. Any ideas?

Essentially... Using update panel, the button press event should trigger the partial postback where your query is rerun that would then allow you to do another databind on your grid. THis would all be followed by a modalPopUp.Show()...

CODE BEHIND

protected void btnAdd_Click(object sender, EventArgs e)
{
    if(!String.IsNullOrEmpty(this.txtMyValue.Text))
    {
         AddValue(this.txtMyValue.Text);
         UpdateGrid();
         this.UpdatePanel1.Update();
    }
    else
    {
       //ooooops
    }
}

private void AddValue(String str)
{
   DataAccess.AddSomeValue(str);
}

private void UpdateGrid()
{
   this.GridView1.DataSource = DataAccess.GetData();
   this.GridView1.DataBind();
}

FRONT END

<asp:UpdatePanel ID="UpdatePanel1" runat="server" updatemode="Conditional">
    <ContentTemplate>
        <asp:TextBox id="TextBox1" runat="server" />
        <asp:Button id="btnAdd" OnClick="btnAdd_Click" runat="Server">
        <div id="MyModalArea">
           <asp:GridView id="GridView1" runat="Server" ..... >
           </asp:GridView>
        </div>
    </ContentTemplate>
</asp:UpdatePanel>

Put popup window content (grid and the rest there is) in separate aspx page and then when you initialize popup window, send textbox value as parameter:

MyPopupWindowContent.aspx?TextBoxValue=something
