Forms Data Controls :: Utilize About 30 Different Database Values From Within A Repeater ItemDataBound Event
Jan 18, 2010
I need to utilize about 30 different database values from within a repeater ItemDataBound Event and I am wondering if there is a better way to do it. I am currently exposing them by doing something like this 30 times:
[Code]....
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.

i 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>
<ItemTemplate>
</Repeater>
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.

I 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.

Just dipping my toe with doing simple VB.NET stuff. Have used classic ASP, so im used to being able to place any field from a recordset whereever i want to putit , and i have just tried to recreate this event.Its got me a bit lost.. now i have read up and understand why it doesnt work - cant use DataItem in a HeaderTemplate - i get that, but how would you do something where you have complete control of the way the table is being set up? and you can use the contents of the container whereever you want, however you want?I just want to be able to get the values from database table, and put them into an html table, in a specific way.

I stumbled into a problem which is that FindControl will only return a control in the ListView after the listview has been databound. Here is the code which is not working, and I'm getting the "Object reference not set to an instance of an object error" when I try to add the attribute to the control:
[Code]....
Any ideas on how I can elegantly fix this?

I am populating an asp.net listview control from my page_load event. Unfortunately, due to my projects requirements, I have to use a third party control within my listviews ItemTemplate that needs to have database values written to its attributes before my listview control is bound, if this is not the case my control flags a null reference exception error. From some investigation into the listview control, it seems that the only way to do this is through my listviews ItemDataBound event as my thrid party control will hold different value depending on each row.was wondering if it's at all possible to force my listviews ItemDataBound event to fire before I call mylistview.databind();?

I wrote the following code in ItemDataBound Event of the DataList
[Code]....
I have got two questions:
1) If I have already given the data type to d as DropDownList, why do we need to typecast it again to e.Item.FindControl("dd1"). Is it because it will typecast this to the data type of the selected item in Drop Down list?
2) Why do we need to write this in Item Data Bound Event of the DataList?

using a listView control... I'm trying to use the ItemDataBound event to map a field's native value to a more 'friendly' name... so far I have the code to access the underlying data so the decision can be made for the actual mapping, but I don't know how to actually change the data displayed?

I am using a DataList to display records from SQL backend in ASP.net 2.0 Framework 3.5. In the ItemDataBound I am setting up a Hyperlink's URL and enabling/disabling it based on data.
The HTML is as follows:-
[Code]....
and in the vb code:-
[Code]....
This is all working correctly in IE, but in Opera, FireFox and Safari while the Hyperlink works, the control is not disabled if Stk.Docs = 0.

I have a databound repeater and in this repeater is an imageButton. How do I pass info from the database into the click event? For example, I've got the description, heading and price fields populating labels, but want the id to go into the imagebuttons click event in order to build a querystring.

I had a scenario where I needed to massage some data before it got bound to a repeater control, so I first thought to use ItemDataBound event to handle it. I assume this would also apply to gridviews, listviews, etc. The pattern I've seen used to do this is something like:
if (it's the right row type, item, alternating item, etc..)
{ someType row = (someType) e.Item.DataItem
someControlType control = FindControl("controlID")
control.PropertyYouWant = row.FieldYouWant }
In thinking about my task, I'm thinking, ok, intercept the data before it's bound, change it, then let it proceed and do it's normal thing... so the step of finding a particular control and assigning the data to a property of it (like 'text' or 'innerhtml') seemed like an extra step to me? do you always need to explicitly assign the data you want to a control to display? For example, say you have a div tag and the field data needs to be it's content. This already happens when I'm not handling ItemDataBound myself to change the data, is there a way to handle the ItemDataBound event to change the data and have it just display where it would if you were not handling the event? The aspx markup already has an <%# Eval("fieldName") %> within the div tag for placement. I know there is an alternative way to handle the call to massage the data right inside the aspx with a helper function like: <%# HelperFunction(Eval("fieldName")) %>, which is what I have used, but I would like to understand the option of using the ItemDataBound event.

Im 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).

Are 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.

I'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?
