Kindly let me know how I can solve this issue.Would be great if you can support your response with necessary code.
I have an error message box that gets displayed somewhat frequently (due to the nature of my program). Some sample code:
<asp:Panel runat="server" ID="ErrorMessagePanel" ClientIDMode="Static" CssClass="messageError"
Style="visibility: hidden;">
<img src="../Images/RedClose.png" alt="close" class="messageCloseIcon" onclick="HideMessage('ErrorMessagePanel');" />
<asp:Label runat="server" ID="ErrorMessage" ClientIDMode="Static" CssClass="messageErrorText" />
</asp:Panel>
The problem is that I don't want to force the user to always click the 'close' button, because these messages popup relatively frequently. I was thinking that a timed fade out would be a good option to follow. However, I can't work out how to call a timer to do a fadeout from my codebehind -- ie. Currently the codebehind sets 'display=block' to show the error, but I am not away that it can also launch some JS to fade out a box.
BTW, I am using Telerik controls, so would prefer to extend those rather than use the ASP Ajax fading extensions from Microsoft (I couldn't get them to work either, as it came up with a conflict with Telerik controls).

im creating site with usercontrols. I have repeater, inside it is another repeater with usercontrol. My problem is passing BindedValue to usercontrol.Bindings works fine and binds the value i need but it cannot pass the value to usercontrol. When i type it manually it works, when i bind it, it passes null (!).I've tried get,set, functions (ondatabound, onload, oninit), accessing control from code with no luck. Ive read and tried to do all the google solutions but with no luck. (even with creating usercontrol inheritance)
View 5 RepliesThere are 2 UserControls UC1 and UC2, and there is one more class C. I want to share the same instance of c in both UserControls. I know that this can be possible with properties in both UC's and by registering UC2 in UC1 or vice versa. But I want the solution to be loosely coupled. Any best possible way without touching the Actual Page (which hosts UC's)? So i need some best possible way between UCs transfering C.

In an ASP.net MVC view, I have 3 partial views. And 3 Partial Views are having "submit" button.
I would like to display error / success message after click on Submit button based on some server side business logic.
have a webpage that has a button and 2 userControl placed inside the placeHolder with visible set to false.When run and click on the button, userControl1 will set the visible to true. Now userControl1 is visible and there is also a button inside this userControl1 and when click, will set userControl2 visible to true and hide userControl1. The code below is the code behide for the webpage the do the above task.

Is there a way to do so that when click on the button inside userControl1, is does not show userControl2? I want to do this way is because, the button is for submitting data to database and then will pop up userControl2. When there is an error, only a msgBox will pop up and does not show userControl2.

What is the earliest time that a control can be focused on without causing an exception/server error? It seems that newly-created (in codebehind) controls cannot be focused on until they're added to the page (or another container on the page), but I'd like to confirm and make sure.

I have multiple questions about doing gridview in code behind.I used this code to fill my gridview at runtime.

My questions are:1. How to edit the column headers? When I bind the database to my gridview, obviously, the column headers of the database will be binded. For example "First_Name", I want to edit the column so I can omit the underscore.2. How to edit the column width?
