I have a link button inside a repeater. How would I directly call the serverside (ItemCommand) method during postback. I want to skip the page_load. The wierd thing happening is, if I put (!Postback) it doesn't execute other methods on postback but it does if I don't set the !postback condition. I have repeater inside a updatepanel in UserControl.

I'm making a call to a web service which returns some data I want to disply in a gridview.The data returned contains two columns "UseDate" & "Quantity" I need to sort the grid by UseDate on pageLoad...I can only make a call once every 120 seconds to return the data.
How can I get the GridView to sort?I have tried couple things but either it does nothing or I get an error... that the Grid fired an unhandled event.
I have a datagrid in aspx page.Inside of datagrid i am using around 15 controls such as Button,dropdownlist and text box

I have an unbound gridview which is bound to a dynamically created datatable during the pageload event of my page. A simple matrix with x columns and y rows. I need all the cells to be the same size. I'll display my code below.
I have a database where a user inputs data to multiple databound drop down listboxes. That's saved to my aspnet database. Then when the page loads again, I want to select the ddls items that the user selected as stored in the database to these databound ddls. But it doesn't work, because on pageload, they haven't been databound yet.
What's the best way to do this? Do I need to run a SELECT statement for each and every ddl on it's databound event?

However when I load the page and as usual the condition that is supposed to bid the data is met, the gridview decides to displays as follows. Is it me or its the Datagrid?
I have a site (ASP.NET), which will display some search results. What I would like to do is load the page with search results, then have the client query my SQL database to check and see if any of the search results have been "Favorited" by the user. I know a little bit about JSON, SOAP, and HTTP Requests, but the only way that I know how to do this right now would be to create a page in my project that I could request from each returned result, and have that page validate the user from the cookie, query sql for the answer, and finally return a true or false to the client on whether to hide or show the "Favorite" icon.
A simple example of this (from everything I can tell) would be the Queue(_) count on Hulu. When I load the Hulu site, it has "Queue", then about 1 second later, it retrieves the actual count, and I get "Queue(1)"
Note: I've been googling and reading, but just haven't found the right resources yet.
I have a textbox with a regex validator attached to it and some stuff in the ontextchanged code behind. This all works fine unless I start the textbox out with Visible=false. Obviously, I'm setting the textbox.Visible to true later on in the codebehind, but when I do this, no postback occurs when the text changes. I'm pretty sure I have isolated the cause to when I change the visible property, but has anyone seen anything like this or know some sort of work around?
I have three tables: Book, author and Book_Author. The third table make them one to many relation.One book may have more than one authors. Book table has Title column and Author table has AuthorName Column.

What is the best way to create procedure or view so that I can call this query and display into repeater ??
I'm trying similar to how I did call a FUNCTION in a Formview with
[Code]....
The page returnes a BC30518: Overload resolution failed because no accessible 'ToString' can be called with these arguments
and marks this below it: target.SetDataBoundString(5, System.Convert.ToString(buchungsbutton(eval("terminid")), System.Globalization.CultureInfo.CurrentCulture))
I have GridView with my own Edit/Update functionality.
What is the best place to put the call for the update function?
I know that placing the Update button will have the click event.
I have extra textboxes and other controls placed on the edit-mode that will have me to find them. So, what is the best place to put the call for the update function that will let me find these controls to be updated?
Is it via GridView_RowCommand and the use of CommandName ?
