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 gridview and when i click on the edit button i will get the modalpopup window which is having a popup window i want to update the data in that details view and refresh the data into gridview also.

I use a hidden Div to print some bills to users, whithin that div there is a updatepanel containing two different datalists.
In client code it calls code behind to do bindings and it does successfully , on success function it clicks some button for updates to take place, here is the problem. updates are not happening.
Is it concerning with using datalist in update panel? for your better digging into problem code follows:

Since my content is embedded in my master page, if I place an update panel around my complete Master page controls including the content placeholders, are the content pages automatically included?
View 3 RepliesWe 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 have an Asp.net page which requires certain sections to be partially updated automatically at an interval of 5 seconds. I was planning to use the good old Timer control with the AJAX Update Panel for this purpose, but after a bit of reading on this control i found out that it may have some problems especially if,
1) The time difference between the async event performed ( 4 seconds ) by the update panel and the Timer's tick interval ( which is 5 seconds ) are quite small, the update panel will be held up in the async operation all the time.
2) Also, the fact that timer control doesn't work very well with Firefox.
I just wanted to get your opinion as to whether if i should go ahead with the timer and update panel approach, write some custom javascript that does the partial page update or some other strategy altogether.
I have a web page into which a user control is loaded. This user control contains a ListView. In the Page_Load event handler of the user control I have this code:
listView1.DataSource = TaskList; // Note: "TaskList" is a data table
listView1.DataBind();
It should be noted that the TaskList data table is actually instantiated in the web page. The user control then obtains a reference to it.
Everything described to this point works fine. Where I'm running into trouble is when I add a new row to TaskList. I had *thought* that the ListView control was dynamically connected to the data table, such that when I altered the contents of the data table in any way, that the changes would be automatically reflected in the ListView.
What is the best way to update data constantly on the client using asp.net Timer + Update Panel, or I need to use Reverse AJAX for that?
View 3 RepliesI have written a Crystal reports web application, that prompts ths user for parameters and then apply them and exports the report to a folder as .rpt and then display the report.
I prompt the parameters on one screen and then display the report on another page. I have the AJAX update panel and update progress controls in the parameter page. When the user enters the parameters and click on ok, I export the report and then loads the report to a session report document and transfer the user to the second page where the report is displayed. I use the following code to do transfer to the seconds page.
I have excluded the report load and parameter assign code here.
[Code]....
In the second page I have the following:
rptViewer.reportsource = Session("rpt")
My problem is this works one time and then stops working the second. What I found out was it comes to the statement:
Response.Redirect("show.aspx")
But it does not even load the show.aspx page. It stays on the parameter page. There are no errors displayed. I could not see any errors when I debug the application also. And out of the blue it works sometimes. And if I remove the update panel and progress control, my report works all the time.
