Crystal Reports :: Control Background Color Changes When Using Group Tree Navigation?

Nov 3, 2010

My web app is using Framework 2.0. I have one Master page and a Detail page that contains a Crystal Report Viewer. The report source is loaded via a dataset.

Here's the lowdown. I have a field (TeacherName) that is in a group header and in the detail. The one that is in the group header has a background color of Yellow. Customer asked me to try another color, so we put in Orange. They decided they didn't like it, so I switched back to Yellow.

When I load the report, the background color of the TeacherName field is Yellow in the Group Header and transparent in the Detail section. Working as planned.

When I navigate to another page using the Prev and Next buttons, the TeacherName field is Yellow in the Group Header and transparent in the Detail section. Working as planned.

When I navigate to another page by clicking on a Group Name in the Group Tree, the TeacherName field changes to the Orange color we temporarily tried. The detail remains transparent as it should. If I go back and click on the Prev/Next buttons, it goes back to Yellow.

Web Forms :: Tree View Control Postback On Click Of Plus Sign When Rendered With RenderControl Method

May 27, 2010

I am using TreeView Control in I have placed this control inside a panel. The tree control is completely binded (we don't want populate on demand) with an Xmldatasource during a callback and then I call Panel.renderControl to return the response (HTML) to the client side callback handler. Problem: 1. The tree expand/collapse (on click of plus sign) is causing postback whereas when I normally bind a tree with xml during postback and without using renderControl of container control, the expand/collapse (on click of plus sign) is being handled at client side. I want to stop this postback and allow tree node to call javascript to toggle nodes as it does when tree is binded and renderd in case of normal page life cycle.(when render control function is not used)

Web Form Render Engine Outputs A Control Tree / Looking For Info On Render Logic.

Feb 12, 2011

I've been watching a video on Scott Hanselmnn teaching MVC 2 tricks/tips. He mentions how MVC 2 by default uses ASP.NET Web Forms view engine to render the output of the views; he mentions that the web forms view engine is a little slower than it could be for MVC 2 since it generates a control tree and then outputs the HTML to the page (I hope I said that right).

I was wondering what he meant by web forms generating a code tree before outputting the HTML to the page. Does anyone have insight on the view engine of Web forms and the steps of the rendering process works for ASP.NET and MVC2?

Web Forms :: Can't Find A Control On Webpage

Jan 19, 2010

I have a web page "Survey.aspx"

This page is in a MasterPage.

In survey.aspx, I put a PlaceHolder.

In this place holder, I dynamically add a usercontrol (for each question in a survey). That usercontrol for now is just a simple Panel with a radiobutton. For the test, I have 2 questions, so the usercontrol will be inserted 2 times in my PlaceHolder.

On a submit button added in my Survey page, I try to retrieve the value of both the radio, but I just cant find the control.

I made a recursive function to loop through all the controls, I find the "PlaceHolder1" controls, but it has no child controls. Where are the 2 panels for each questions .. both containing 1 radio.

I see them on screen, but just can't find them in my coding.

This is my Survey.aspx layout code


This is my usercontrol layout code

C# - How To Load A User Control Dynamically In A Webpage

Nov 29, 2010

How to load a user control dynamically in a page?

I have a page that contains radioButtons. Each click on a radio button loads a user control (.ascx) in the page.

What I am doing is loading all controls at the same time, but set their visibility to false. When a user clicks a radiobutton I set the visibility of the specific user control to true.

As a result I am loading all the user controls on each postback.
