I am using a repeater control and i want to use one more repeater control inside the existing repeater control .
Like this:
<asp:Repeater ID="Repeater1" runat="server"> <HeaderTemplate> </HeaderTemplate>

</ItemTemplate>

Suppose i am having 25 character length string and I want to bind only first 15 character of that string into the label control.
<a href="[URL]" >"<span class="name" style="text-align: left; font-family: Arial; color: #0094DA; font-size: 14pt">
<%#Eval("Name").ToString().Length >= 30 ? Eval("Name").ToString().Substring(0, 30) : Eval("Name").ToString()%></span></a>
In my gridview, I have 6 columns. The first 5 columns are filled with data retrieved from database.In the 6th column I want to display a value from textbox from same form. The value should be displayed on the row next to last row of rest of the columns. So my last column (i.e.) 6th column will just have all the rows filled with the same value of the text box.
First 5 columns of grid will be filled by selecting the college name from dropdown.The last colum (Date) must be filled with the date that is given in the textbox.It can be even after button click event(date of attendence).
It can be done after button click event also..

View 1 RepliesI have a label control inside of repeater and I can't seem to get FindControl to locate the label inside of the repeater or even the repeater itself.

View 1 Repliesaspects of some controls in Code Behind (VB) with controls inside a datalist and/or repeater. I have read a lot of stuff on using some tricks but none seem to work so far. I am new to ASP.net so some of the explanations are too cryptic as well. Below is a section of code that I am trying to change. This example is attempting to make the label visible if the dataitem is true and hidden if false. No matter what I seem to do I cann't reference this label to change. I also want to change the text on some other controls in this dataitem if the returned value is a certain value.

I have a button on a page with a Repeater and an ObjectDataSource. To give credit where credit is due, the Repeater's paging functionality is courtesy of ScottGu. (However, I'm using ASP.NET 4.0 and SQL Server 2008, as opposed to ASP.NET 2.0 and SQL Server 2005.)
Anyway, in the button's click event, I need to access the Text property of a Label that's inside the Repeater because it's used as an input parameter in a stored procedure. I'm getting a NullReferenceException when trying to access the Label's Text property. I have researched this error and have tried a few different solutions (involving FindControl and the Repeater's ItemDataBound event), but I haven't been able to get it to work. The code is below.

I 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?
