Forms Data Controls :: How To Access Attributeid Values In Repeater Control's ItemDataBound Event Handler
Jan 15, 2011i have simple repeater control on my page:
<asp:Repeater id="Repeater1" runat="server" DataSourceID="SqlDataSource1">
<ItemTemplate>
<asp:TextBox id="txtBox1" runat="server" Text='<%#Eval("attributename") %>'></TextBox>

I'm bounding data to repeater control by using SqlDataSource Control
bounded data is something like this:
attributeid attributename
1 color
2 size
How can I get access to attributeid values in Repeater control's ItemDataBound event handler,
I tried to use DataBinder.GetPropertyValue(container,"attribuetid"), but I can't set container, am I doing right, or maybe I should use another approach.

Forms Data Controls :: Utilize About 30 Different Database Values From Within A Repeater ItemDataBound Event

Rather than making 30 declarations, is there a way I can make them all available as short variable names? The variable name could be the same as the field name.
Raise ItemDataBound Event From Repeater Within User Control To Page?
May 20, 2010I have a user control that contains a repeater. We have added some paging and sorting into the user control and it all works well.
What I need now is a nice way to catch the OnItemDataBound event of the inner repeater and then bubble it up to be accessible directly from the user control from within the page.
We have tried catching it and then declaring it in the user control but it just won't work.

Repeater Itemdatabound Event Value Type And Reference Type?
Mar 29, 2010Im trying to bind a list with datetime objects to my repeater.
if (e.Item.ItemType == ListItemType.AlternatingItem || e.Item.ItemType == ListItemType.Item)
{
DateTime actualDate = e.Item.DataItem as DateTime;
}
When I want access the itemdatabound event on the repeater Then I get an errormessage which says that DateTime is a valuetype and not a reference type.My solution is that a wrap the datetime in a custom object (reference type) and pass that to the repeater datasource instead of the datetime. But Im wondering if there are other solutions where the repeater takes valuetypes (DateTime objects).

Forms Data Controls :: C# Set Values Of Repeater Control Values In Code Behind?
Apr 2, 2010I have a repeater that I have bound to a sql reader via my code behind page.
However I can't figure out how to populate the controls in my repeater in my code behind code.
At the moment I am having to specify the database field e.g productprice with the control in the .aspx page like this
<asp:Label ID="LabelUnitPrice" runat="server" Text='<%# Eval("productprice") %>'></asp:Label>
I would rather specify fields in my code behind than embedding them in the .aspx page.
I also have a subtotal label control in my repeater that I would like to populate its text property by mutiplying two of the database values e.g productprice * unitprice shown in my repeater.
I need to do this in code behind, looping through the repeater. Any idea of how I can do this in C#?
Repeater Controls' ItemDataBound - Handle Inline Or Codebehind?
Oct 12, 2010Are there any differences between coding row-specific stuff inline within the repeater's template and doing so in the codebehind file in ItemDataBound?
EDIT: Re: differences - I think we're all agreed it makes for markup that's nasty to read/maintain :) I was thinking of performance benefits.
Jquery - Secondary Repeater W/ ObjectDataSource Databind Event Fired From Another Repeater's Click Event?
Mar 29, 2011I'm having trouble managing how to call upon databind from clicking on a row over an already populated repeater that will populate data regarding the row clicked TO another repeater on the same page.
I've succeeded doing that with postback, calling a jquery click event of that row, taking the data of the specific row and passing it onto a "Querystring" and after postpack, it will be pushed into a Session which the ObjectDataSource of the secondary repeater will recognize and populate the data tables accordingly.
The problem is, I must do it without a postback or in other words purely on client side.

Eval And ItemDataBound Or RowDataBound Event To Display Data Which One Is Better?
Nov 4, 2010Which method is better (performance-wise) if I have DataBoundControl such as GridView, Repeater, and/or DataList and I use the following method to display data:
Eval("ColumnName")
or handling the ItemDataBound or RowDataBound event like:
void Repeater1_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
// my code to display data here
}
I prefer the second one for code readability reason, but for performance reason, are they the same (or are they even the same thing)?

Web Forms :: Creating Dynamic Controls In ListView's ItemDataBound Event?
Jan 12, 2011I'm presenting a list of products within a ListView. Each product can have associated "Options" (Size, Colour etc), but may have none. For each product that gets added, I need to render a dropdownlist for each of its options. E.g. A "Colour" dropdown might have "Black", "White", "Red" etc. I need to generate these controls dynamically, as they are defined by the data itself.
So far, so good. The dropdowns are rendered, and everything "looks" good. The trouble is, I can't work out how to actually get it to work. .Net is complaining about "EnableEventValidation", and ViewState won't work as I've added the controls late in the page's life cycle. As these controls are dynamic, I don't know how to pick up the selected values, and persist them on a post back! When the user clicks on the "Add to basket" option for the product, I need to determine which options the user has selected, and add them to the basket.
Am I missing something here? Is there an easier way of achieving this? I kind-of feel like I'm in a "chicken and egg" situation here. I can't create the controls until the data is loaded (in the ItemDataBound event), but that too late for ViewState. Is there a generally accepted best approach for achieving this sort of thing in ASP/Net?
