Forms Data Controls :: Aborting Item Creation In Bound Repeater
Apr 9, 2010
I have what's bound to be a stupid question, so I'll apologize for what I think should be an obvious answer my brain just can't see. My problem is very simple. I have a Repeater control bound to a SqlDataSource. The ItemTemplate in this case is one complicated beast, and rendering can take a loong time if too many records are returned; so I need to maintain tight control over how many records are brought back from the data source.
Is there not some way of either stopping the creation of subsequent RepeaterItems once a certain count has been reached, or cancelling the bind if more than a certain number of records are returned? I know I can grab the record count from the AffectedRows property in the Selected event of the DataSource, but I've encountered a brain-lock on how to stop/inhibit the binding (or RepeaterItem creation beyond x records).
I'm happy with either aborting the binding altogether if the record count is too high (displaying no records), or simply stopping it after X records are returned; at this point, I'm not picky. Either way would work, and it seems I ought to be able to readily figure out either one, but my brain has simply gone into neutral.

I have to set a LinkButton's OnClientClick attribute but I don't know what this value is until the LinkButton is bound to. I'm trying to set the value when the repeater binds, but I can't workout how to get the 'boundItem/dataContext' value.
<asp:Repeater ID="Repeater1" runat="server">
<ItemTemplate>
<asp:LinkButton Text="HelloWorld" ID="Hyper1" runat="server" OnDataBinding="Repeater1_DataBinding" >
</asp:LinkButton>
</ItemTemplate>
</asp:Repeater>
protected void Page_Load(object sender, EventArgs e)
{
var list = new List<TestObject>();
list.Add(new TestObject() {TestValue = "testing1"});
list.Add(new TestObject() { TestValue = "testing2" });
list.Add(new TestObject() { TestValue = "testing3" });
this.Repeater1.DataSource = list;
this.Repeater1.DataBind();
}
public void Repeater1_DataBinding(object sender, EventArgs e)
{
var link = sender as HyperLink;
//link.DataItem ???
}
Is there anyway to find out what the current rows bound item is?

I have a repeater control:
<asp:Repeater ID="rep" DataSourceID="XMLDSCompare" runat="server">
<ItemTemplate>
<h4><%# XPath("title")%></h4>
</ItemTemplate>
</asp:Repeater>
Now if its the first item in the total resultset, I want to add <div> to ItemTemplate control, if its the 2nd item, I want to add </div>
So output would be (not including table tags generated by repeater control):
<div>
title 1
title 2
</div>
<div>
title 3
title 4
</div>
<div>
title 5
title 6
</div>
How would I do this in the ItemDataBound event of repeater control?

I had a web application that was binding a IDataReader to a repeater control. I converted the project from 3.5(2.0) to 4.0 and then I received the error:
An invalid data source is being used for rptData. A valid data source must implement either IListSource or IEnumerable.
So, I used a datatable instead and the binding worked. So it seems that they have removed this functionality with .NET 4.0.

I have a databound FormView with a dropdown list of categories. All works as expected, but I want to provide the facility for the user to add a new category to the list and I can't find an elegant way to do it. My current approach is to have a simple modal popup (Ajax toolkit) with a FormView (bound to the Categories table). That successfully inserts the new row, but it doesn't show in the dropdown so it can't be selected. I can force a refresh by calling formview.DataBind() in a suitable event handler, but that of course moves the formview off the selected record and loses any changes the user may have made.
Is there a convenient way (perhaps using AJAX, avoiding a postback entirely) to update the Categories table and refresh the dropdown without moving off of the current FormView's record? I feel sure this
must be a frequent and basic requirement, but I've not found any mention of how to implement it.

I've got a repeater bound to a datasource through the code behind. Everything is working fine so far except for this, I'm trying to concactenate a bound field as the id on a query string to an image handler:
<asp:Image ID="Image4" runat="server" BorderColor="#E5E5E5" BorderStyle="Solid" BorderWidth="1px"
Height="100px" Width="100px" ImageUrl="'~/ImageHandler4.ashx?Id=+'<%# Bind("ImageID")%>'"/>
What am I doing wrong?

How do i dynamically change the value of dataitem in repeater control(.net 2.0,VS 2005)..i have repeater something like this :
<asp:Repeater ID="rptGameInfo" runat=server OnItemDataBound="itemDataBound_rptGameInfo" >
<HeaderTemplate >
</HeaderTemplate>
<ItemTemplate >
<asp:Label ID="lblLoc" runat=server Text="Location:" ></asp:Label><%# Eval("GAME_LOCATION")%><br />
</ItemTemplate >
</asp:Repeater>
and it shows the result like this:
location:"Select"
If location is "Select" i want to change it to "n/a". So i am trying to capture it in itemDataBound even something like this
if ((e.Item.ItemType == ListItemType.Item) || (e.Item.ItemType == ListItemType.AlternatingItem))
{
DataRowView row = e.Item.DataItem as DataRowView;
string location = row["GAME_LOCATION"].ToString();
if (location == "Select")
{
// e.Item.Text = "n/a";>>
}
Does e.Item some 'text' sort of property ,i can set the value to?

I am learning how to use repeater. I added two links to my repeater, a delete and an edit link. However, when I click either delete or edit link, they both take me to same method. How do I add the link such that when I click on edit, it take me to an edit method and delete takes me to a delete method. Below is a sample code.
Also, how do I delete a single row in a repeated. For example, I have a simple form that display an item description and a quantity. There are six item display on the form, but I wish to delete the third item. How can I pass in an id that will delete the third item rather than delete everything (i.e where item_id = 3)

I have a DataList control setup with a Repeater inside it. It's displaying Ranks just fine, but the problem is I don't know how to make it start over with each DataList.
Right now, if there are two rows in the PointsCat table, it creates two DataLists (new DataList for each ID) and populates the Repeater with the person's rank, name and points from the Points table. The CatID in the Points table is a number equal to an ID in the PointsCat table (to tell which DataList's Repeater to display the data in). This code currently just orders ALL the entries from my database table, so the first Repeater in the first DataList may end with a ranking of 4 (4th), the first item in the next DataList's Repeater starts with a rank of 5...instead of starting over with 1.
So my current page may show something like this (notice the rank didn't start over in the second category):
Points Category 1 Points Category 2
1 John Doe 400 4 Janet Doe 275
2 John Smith 390 5 Johnny Smith 270
3 Jane Smith 380
My SqlDataAdapter line is below. I need it to start over the ranking for each CatID. Is it possible to do that within this line?

I've done things like

before in my asp code, calling some public function in the codebehind. But now I'm trying to do this from within a repeater item. The message I receive from the compiler is: "The name 'somefunction' does not exist in the current context." Error 97 The name 'getclass' does not exist in the current context 169

I have one repeater on page which has his own sql data source. I've placed 2 dropdown lists on the page. The repeater has jQuery DataTable plugin. With 2 dropdownlist I wish to change the sql stored procedures so when each will be selected the data in repeater will change. When user select the first there will be only data (users) according to selected item and in the second the same. I wrote 2 simple functions for changing stored procedure of repeater and rebiding it. Everything works but when I try the second one and then the first I always get warning about error "Procedure or function .... has too many arguments specified".
I think that when I select the first one the second function is still called although I don't call it.
