Let me check whether I understood your requirement. Entering ManagerName in ManagerTextBox and clicking on searchbutton, Then the result will be shown in TrusteeNametextbox which is in a popup?

means whenever txtlinemanager textbox is filled with some id then the txttrustname textbox should auotmatically be filled with trusteename on behalf of that particular id in txtlinemanager textbox ...

Have posted as a solution...try and revert

Set your ID field to have autopostback = true, then call the method on postback.
Try as below

<asp:textbox id="TextBox1" ontextchanged="TextBox1_TextChanged" autopostback="true" runat="server" ></asp:textbox>// ManagerTextbox

In CodeBehind:

protected void TextBox1_TextChanged(object sender, EventArgs e)
            TrusteeName(); // assuming that this method fetches the required Trusteename from Db

Hope this helps...
