Forms Data Controls :: Repeater Onitemdatabound Works Only One Time?
Jul 28, 2010
I have 3 nested repeaters for a dropdown js menu.
<asp:Repeater ID="Repeater1" OnItemDataBound="rpaltmenu" runat="server">
<ItemTemplate>
<li>
<a href="<%--<%#"sirt.aspx?anamenuid="+Eval("menuid") %>--%>"><div align="center"><img border="0" src="<%#Eval("ikon") %>"><br /><%#Eval("menuadi").ToString() %></div></a>
<ul>......
code is ok but works only one time and my last menu items are being loaded only for one time.The first items are ok but after that it is not working.

This is my Repeater with event OnItemDataBound to resize image.Actually, sub resizeimage is get image url from Label "Imgurl" to get width and height of image. Then set new width and height to asp:Image "Img" to make a thumbnail.

I have added a event for my datalist present inside a update panel as
[Code]....
When the UpdatePanel is updated for the first time, the function 'DataList1_ItemDataBound' is called.But, when the updatepanel is refreshed for the second time, the debugger doesn't reach the same event at all. thus keeping all the data inside the datalist same.

I have a problem with my first ASP.NET webpage. Im using ASP.NET 3.5 with VisualStudio 2008 and LINQ to SQL.
To easier communication we take a example from northwind data base. I want to list all the Orders and for each order I want to list all its OrderDetails. I have created a listview (lvOrders) with a LinqDataSource (Order table). Now I have create a new nested listview, for the order details, but I dont know how to load the orderdetails in this nested listview. I have tried to load the orderdetails in the OnItemDataBound of the first listview (lvOrders), but I miss functionatilly like DELETE command on the nested listview (to delete a orderdetail) This is my code:

On code behind:

Im thinking on some like a unique linqdatasource, returning a new Order entity (modified) with one field that is a list of orderdetails... this would work?

I add one or more textbox controls to a repeater itemtemplate during OnItemDataBound.
The textbox controls are instantiated and then added to a placeholder.
My problem is getting the user entered values from those dynamically added textboxes. They do not seem to exist in the repeater items collection.

I have a user control that displays a shopping cart in an ecommerce application.
The main cart display is a repeater that renders as a html table. In one of those table columns, there is another repeater to display people associated with the products int he cart (it's a repeater in case there is a line item >1 with multiple people).
I've added an ImageButton that I want to use to change the person associated with the item. At first, when I'd click on it I was getting this error:
Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.
So as an experiment I disabled EventValidation on the page (not the control it's self) and now I do not get an error, but I also do not ever hit the breakpoint I set in the innermost repeater's ItemCommand event.
So I wonder how I might do this without disabling EventValidation, because this control will show up on multiple pages and we don't want to edit them all. Also, I'll need to know not only the repeater containing the control's row that the event came from but also the row index of the repeater containg this one. Is this possible?

I'm so confused I wasn't even sure what to make the title so that it would make sense.
Here is what I have:
[code]...
I have links at the top of the page that are the letters A-Z. What I want to do is click on one of the letters, then show only the div IDs that start with that letter. I can't figure out how to do this since I'm dynamically creating the ID names. I had it set up nicely with Javascript and CSS, but the function call was inside the repeater. The layout is changed now, and I don't understand how to make the div ID available outside the repeater.

I've been searching for hours trying to figure this out. I understand that somehow I need to recreate the control in page_load. I think seeing the code will let us better understand what I'm trying to do.

what changed do I need to make to my code for it to achieve what I'm after.
At the moment I am getting a "cannot cast to type" error message with the below code.
I have also tried calling the ItemDataBound method in with the parent repeater tags and had no errors but when I clicked on the button it would just move back to the top of the page and would not hide or show any data. Also I have made the div style to none but the first record still shows its child but the rest don't.

I have two update panels on my page. One of them contains a list of users which is retrieved from the database. When I click a search button (which is outside of the update panel) the users are retrieved from SQL server and displayed in a repeater inside this update panel. Each of the users has a button next to them to 'Edit'. The seconds update panel contains all of the fields for a user. Textboxes, checkboxes and what not.
My plan is to click the search button as you normally would, and then when you click the 'Edit' button on a user, the second update panel fills with their details. This works except that when I do this the first update panel is updated again and because it hasn't searched for any users it goes blank.
So what I did was set both the update panels to conditional, and then call the first panels update at the end of the search code in the search button click event. So that worked, but now the repeater inside the first update panel is not firing the Item_Command event, so I can't get the details for a user. How can I resolve this so that the repeater button works inside the conditional update panel?

I have datagridview with paging enabled. But when I want to move from page to another page in the grid, then it only works when I press the 2nd time on some other page. I read some on the internet that I need to bind the data of the gridview but the thing is, I cant bind the data again because the gridview was filled with data in the page_load from querystring and I dont really want to go over the querystring again in the PageIndexChanging function.
protected void searchGridFA_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
searchGridFA.PageIndex = e.NewPageIndex;
}
So why does the page changes only from the 2nd time I press it?

how to suppress the "AM" in the gridview (template Bind("RideTimeMin", "{0:t}")? Don't tell me to use military time because the function is not "time on a clock"; it's how much time is allowed for a task (in this case the min/max hours & minutes that horses have to complete a 20 mile trail; e.g. 05:00, 05:27, etc). I'm currently accomplishing this in the "ondatabound" function by "..RTmin.Replace("AM","")". I have looked and looked at all the websites that talk about datetime formatting but have yet to find a way to do it upfront in the gridview bind statement.

I Have gotten the logout authentication to work. THe problem was that after logout u can back browser back into the app. Now it does redirect to the app login screen, but this is good only one time.

I would like to know how to get this logout process to work all the time. here is some code i have pertaining to the authentication process:
