I have a repeater control with a delete button on each row. I also have a link on the same page (not within the repeater) that I only want to be visible when the repeater contains at least one row.
My problem is that, when the delete button on the final row is clicked, this triggers a postback during which the ItemCommand event is called to process the delete click. However this event is processedafter the Page Load event in which I would normally render or not render the conditional link. So I don't know at the time I'm rendering the link whether the user has just deleted the last row.
Am I misunderstanding the chain of events or is there a better way of handling this? Could I, for example, determine from the Sender & e arguments available within the Page_Load event, that the postback has been triggered by clicking the delete button in the repeater? The only other way I can see of dealing with this is to force a second postback once the final row of the repeater has been deleted which seems like overkill.
how can i set the max-width of the label field, and use multiple line if the text length larger than max-width in the templateitem of repeater. i set the width to 10, but can't fix the length.
View 4 RepliesI have a web page that has a repeater bound to a data source. I beed to change a label inside the repeater based on the data that is in each repeater item. For instance, for the first item it might be one thing, and for the next item the label may be something else. I am currently doing some processing in the prerender event, but I don't know if I can or how to access the data source fields there. Where and how do I get access to the data in each item so I can change the label text?

<asp:Repeater ID="repeaterReportListByJob" runat="server" DataSource='<%# GetReportsByJobNID(Eval(Container.DataItem, "JobNID")) %>'>
It seems my Eval(Container.DataItem, "JobNID") is not working and I assume this is because the datasource of the outer (parent) repeater is an anonymous type. So how am I supposed to access a particular field of my anonymous type?

What function do I use to reduce all entries in a database field to a maximum length. The field is 100 characters wide and I need to chop all existing entries in the field down to 20 characters. I prefer not to redefine the field to 20 wide to lose the data and then redefine back to 100.
UPDATE CmpyInfo
SET ( ShortName to 20 characters max )
WHERE ShortName.Length > 20
I have a page with a Listbox and GridView.
The Listbox has a list of students. The Gridview has a list of classes offered during a period, such as:
Math Science English etc. When I click a student in the Listbox, I call a sproc via Linq, and get the ClassID and ClassTitle that student is registered for.
What I need to do is Highlight the record in the GridView that matches the ClassID or ClassTitle returned by the sproc.
Previously, I used a ListBox for the Class Offerings. This is easy with a Listbox using the FindByText method:

What is the right way to do this with a GridView?

I have a two-character field for US State. I add a RegularExpressionValidator control to validate the input using
ValidationExpression="[a-zA-Z]{2}"which works to validate the content when something's entered, but it doesn't catch if someone just leaves the textbox blank.
Is there any way to validate within the same regex to catch an empty textbox?

I am finding it difficult to accept that the whole Repeater approach has any benefits over just creating a loop in code, iterating through a recordset, and building a html table into a variable, then dumping it to the page. This repeater is spawning pages of code and objects, and surely this is all using up server resources.
