And close modal Popup when clicking on cancel button.2) How to navigate to other ".aspx page", when clicking on Gridview "Hyperlink" OR "ImageButton" inside above Grid.

Forms Data Controls :: Calculation On RadioList Inside GridView - How To Retrieve The List Button Clicked Value

Jan 19, 2010

Here is my page:

[Code]....

It basically is 4 questions with each answer assigned a value.

What I would like to do is when the button is clicked the selected values are retrieved and calculated to give a total.

That total is then compared against some common totals and the next value is shown.

So is the total is 8= Very Good, 6= Very Bad, 4= Terrible etc.

The two labels Result and Truth would sho the numerical result and the truth according to the scale.

I am at a loss on how to retrieve the list button clicked value, how to add them up and referance that to the Truth result.

its complicated (to me its "bang head against wall" difficult.

LinkButton Inside UpdatePanel Disappears After Partial Page Postback?

Mar 24, 2010

I have a linkbutton inside a updatepanel and when the update panel does a partial page rendering, the linkbutton disappears.

<asp:UpdatePanel ID="up" runat="server" ChildrenAsTriggers="true" UpdateMode="Conditional">
<ContentTemplate>
<asp:DropDownList ID="drp" runat="server" AutoPostBack="true" CausesValidation="true">
<asp:ListItem Text="" Value="" />
<asp:ListItem Text="a" Value="a" />
<asp:ListItem Text="b" Value="b" />
<asp:ListItem Text="c" Value="c" />
</asp:DropDownList>
<asp:LinkButton ID="link" Text="abc" runat="server" />
</ContentTemplate>

I think that is because the link button is rendered using a script and that script is not run after the post back.

How To Make .net Page Postback When A Control Is Clicked Inside A JQuery Dialog

Oct 18, 2010

I'm having some trouble with jQuery UI. I've created a dialog with jQuery UI: so far, so good. I set up a form inside the jQuery UI dialog and then it's another story. I've written a very simple page to illustrate:

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="testpage.aspx.cs" Inherits="RiverCascade.testpage" %>
<head runat="server"> [code]....

In the code above, see that I've just imported the jQuery, jQuery UI, and stylesheets and set up a page with a dialog box. There is an asp control button1 outside the dialog box and an asp control button2 inside the dialog box.

When I click on button1, the event handler gets called and all is well. However, when on click on button2, the button inside the jQuery dialog, nothing happens.Why is my web page behaving this way?

Forms Data Controls :: GridView RowDataBound Always Fires On Partial Postback?

Mar 1, 2010

I have one UpdatePanel which contains search criteria controls for a GridView.

The GridView is in another UpdatePanel.

I have a reset button in the search criteria UpdatPanel which resets all the search controls to their default values. However when I click this button for some reason my GridView RowDataBound method fires.

This is slowing the page down when the reset button is clicked. Does anyone know why this is happening and how to stop it. I haven't posted the code and explained it in plain english for ease of reading.
