View 3 RepliesI have one repeater control in my web page.
And i want to bind this repeater control from button.
But button is in Update panel in ajax.
And repeater control is outside the updatePanel...
I am using asp.net 3.5 c#. I am trying to do this:
In one page, a user can insert some stuff (name, phone .. etc) to the database. And then the user should be able to see the rows he added as a list automatically in a datalist (or other control). As he inserts rows, it appears in the datalist.
I tried to use update panel and inside it datalist, with a button as a trigger but it did n't work with me!
I have a user control, that has an update panel and update progress control in it.
I use this user control in more than 1 location on the same page.... problem is, when ucA posts back, I see the update progress control for both ucA and ucB. I assume this is because it is a user control and the update panel and progress are named the same?
Either way - how do I make it so that the update progress only displays for the proper user control?
I have a web page devoloped in visual studio 2008.I have 4 dropdowns and a repeater in the page.based on the selection(search criteria) from the dropdowns the repeater value will change and one dropdown selection will bind values to the other dropdown also.Since the page is causing a lot of postback we decided to implement ajax here.I am yet to learn ajax.which ajax control replace dropdowns?
i have already server side code written on all dropdowns.Please give me a good solution which i can implement in less time and reuse my code.One more update: i have a master page used in the project.I am using update panel of ajax which does not work if i use master page.(That means all the dropdown controls and repeater i put it in update panel.But still page postback occurs.)In a normal page(without master page) it works?
I've exempted the irrelevant bits of code. Essentially, I am trying to change the URL of an image control inside of an update panel inside of a custom user control from a function called inside an update panel from my main page. Using UpdatePanel.Update() isn't working: I end up waiting for the next full page POST to occur before all the updates I make to CustomControl from buttons within the main page's update panel are visible. I verified that Update() was being called via the debugger: there are no issues in that department.
Here, you can see Custom Control and the Button declared. The button is in an update panel to avoid giving a full POST and causing the whole page to reload.
<cust:CustomControl runat="server" ID="CustomControl1">
<asp:UpdatePanel runat="server" ID="UpdatePanel1"> <ContentTemplate>
<asp:Button id="Button1" runat="server" OnClick="DoStuff" />
</ContentTemplate> </asp:UpdatePanel>
This control stores images within their own seperate update panels because rerendering the images is very slow (it requires processing arrays of millions of datapoints) and the user only ever needs to modify one image at a time. I'm using Image1 as an example.

I have a user control which is inside a update panel.This user control has a event like

Inside this i am checking a checkbox which is outside the update panel.
But it is not checking the checkbox ?
In firebug i found that the html for that checkbox is not rendered.
What is the way to do that?
We have two update panels on our webpage. Now first update panel is having button cancel. While second update panel is having a file upload control.
Now if the user uploads a file that is going to upload in about 2 mins, and in between, say after 30 seconds the user clicks the cancel button, the upload taking place in update panel 2 should stop.
How do we achieve this ?
I'm creating an ASP.NET Control which has a property collection for Columns which the user can edit in the Property Collection Editor..
In most circumstances this works fine, the collection can be edited in the designer and the appropriate tags are added inside the control in the ASPX file.
It works fine when
My control is added to the form
[Code]....
My control is added inside an Update Panel
[Code]....
[Code]....
However, if My control is inside a Content Placeholder which is inside an Update Panel, it fails to work as it should. In this scenario, when the Columns collection is edited in the designer, if you then switch back to Source view, the Columns collection is emptied. I have to save the aspx page before switching back to Source view for the changes to be kept.

how to get around this problem? Is there something I may have missed?
Here's the code for the Control

So how to add an item to a repeater?
I think one answer is to maintain a datatable and bind to the repeater, is there any other options?
