Forms Data Controls :: How To Access Attributeid Values In Repeater Control's ItemDataBound Event Handler
Jan 15, 2011
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 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 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.

I have a repeater bound to a datasource that servers as a list of birds. When the user clicks an item in the list the bird's image is displayed on the page. I want to change the background color of the item that is currently selected in the OnClick handler for the main item in my repeater's ItemTemplate.
I have changed the styling of controls prgrammatically before and it worked fine but in those cases i used the ID of the control to directly access it in my code behind file. But since this is some arbitrary item in a repeater I don't know it's ID at runtime, all I have is the sender object passed to the control's OnClick handler. So in my code behind file, I tried casting the sender object passed to the OnClick handler to the appropriate type and used Style.Add("background-color", highlitColor) but it failed to change anything.
I had a thought - maybe this sender object gets passed by value so all I did was change the Style of a COPY of the control item.
If this is indeed my problem, how do I start with a casted sender object in an event handler and get a reference to the actual control in order to change it's Style?

I 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#?

how I access /retrieve values of checkboxlist inside a repeater? My code is below..is it the same as if it was not inside a repeater? My other concern is how do I distinguish these checkboxes because basically what 's going to happen here is based on which checkbox is selected I need to query an xml file to get the location of a folder which I'm then going to zip up and allow user to download..So here's the breakdown. I have an accordion panel using jquery ui. Each panel hold a product and each product has the same checkboxes..so depending on which product the user wants to download files for which he/she will indicate by opening the accordion panel for that product and checking which checkboxes/file they want to download . So how will I know which product the user clicked the checkboxes for being that I'm using this repeater which just one ID?
[Code]....
can I still use this code or will it not work cause it's inside a repeater..also I was going to use jquery to add an onclick event to the checkbox so how can I do that now with me using this control?
[Code]....
Here's another issue..I can't even assign values to the checkboxlist using databinding..so how am I suppose to do this.. Server Error in '/ArchitectView' Application. Parser Error Description: An error occurred during the parsing of a resource required to service this request. Please review the following specific parse error details and modify your source file appropriately. Parser Error Message: Databinding expressions are only supported on objects that have a DataBinding event. System.Web.UI.WebControls.ListItem does not have a DataBinding event.Source Error:

I previously had a datalist bound to an objectDataSource. Within the ItemDataBound event, i could quite happily access the current bound row as follows:
[Code]....
where ASPNETDB was the database and tblJobs the tableadapter. I could then reference the tblJobs items as job.JobId and job.StartDate etc. Upon chainging the datalist to a listview, I can't seem to find any way of accessing the same data. I've tried ListViewItem and ListViewDataItem, is this the right method or am i missing something?

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:

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:-

and in the vb 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.
