Setting textbox value inside modal popup

Posted By:      Posted Date: October 05, 2010    Points: 0   Category :ASP.Net

Question from a newbie:

In the problem code, there is a modal popup that is shown using .Show, and that part works fine.  A textbox in the popup needs to display text, but I can't get that part to work.

testModalPopUp = Page.FindControl("ExampleModalPopUp")
testTextBox = Page.FindControl("ExampleTextBox")

testTextBox.Text = "something goes here"

Is there something I'm missing?

How to Pass Grid Row to Textbox on Modal Popup?



I have a panel with a textbox on it.  In the GridView I have a button in a template.  I can send the row data from the button's OnClick to the text box easily enough. 

                <asp:TemplateField ShowHeader="False">
                        <asp:Button ID="Preview_btn" runat="server" CausesValidation="false" 
                        Text="Preview" OnClick="GoToPreviewPage"/>

 Protected Sub GoToPreviewPage(ByVal sender As Object, ByVal e As EventArgs)

        Dim row As GridViewRow = DirectCast(TryCast(sender, Control).NamingContainer, GridViewRow)
        Dim myRowIndex As Integer = row.RowIndex

        Textbox2.Text = Gridview1.Rows(myRowIndex).Cells(1).Text

End Sub

When I added the ModalPopupExtender to the button and pointed it to the panel, now the button's OnClick event and OnClientClick and CommandName no longer fire.  The Popup works fine, I'd just like to be able to pass the RowID to i

Alert popup on Gridview Textbox Click

Hi,I am trying to make a Javascript Alert appear when someone clicks on a textbox that is part of a Gridview. the textbox is an Item template and I have an onclick="NotePopup()" in the TextBox properties. I am having trouble grabbing the correct ID of the text box, because it is nested inside a gridview. I have been looking around on Google for a solution but none of the responses are working for me.  The gridview will have multiple rows, so each textbox that could potentially be clicked will have a different ID, is there any way to pass the correct ID to the Javascript, or have the Javascript function grab the correct ID?I did use var Control = '<%= GridView1.ClientID %>';then cut and paste the ID from ViewSource of a textbox and append it to the Control Variable,  to test out the popup and it does workThanks for your helpChris
