Forms Data Controls :: Databinding A Repeater Control Twice In The Same Code?
Aug 4, 2010
I have a asp:repeater control which I am using to display a photo and the Name. So for this I have to execute SQL query and unfortunately I dont have the control of the database - table design. So the photo comes from one table and the Name comes from another table. I wrote 2 sql queries to get both these information created 2 sqldatareader. So now I have to bind the repeater control to both of these reader. But I know it does not work. Is there any other way I can do this? I even tried to nest a repeater control inside another. But that does not work anyway.

I have a strange problem. I have made a PagedRepeater control, which inherits from the Repeater, from a tutorial I saw here: http://www.4guysfromrolla.com/articles/020905-1.aspx. It's in VB and I'm in C#, and it didn't quite have all the features I was lookingfor, so, I've modified it quite a bit. I added support for a SqlDataSource control, as well. The only problem is, that it always returns the first item from the SqlDataSource, even when the CurrentPageIndex on the PagedDataSource is set to a different value.

I have a composite control inside a repeater. I am trying to set the controls public properties inline like so (this is a simplified example):
<uc1:Control runat="server" ID="id" Value='<%# Eval("value") %>'>
When I place the repeater inside a user control INSIDE ANOTHER user control and onto the page this works - the property is correctly set, if I inspect it inside the EnsureChildControls() method of the custom control the composite control's Value propertyis set to Eval("value") as intended.

I have a forms view with an EditItemTemplate. I would like to populate the EditItemTemplate using the code behind vs. mixing the data in the UI as so:
text='<%#Bind("Question") %>'
At what point do I do this? I thought it would be on FormView_DataBinding, but there is no e.item.dataitem like other databound controls. My issue is that I need to check criteria of the data prior so I know which inputs to make visible, to set properties of controls within the EditItemTemplate, and manipulate the data prior to binding (less of an issue as I can always just tweak the data prior to binding, but it doesn't solve my other problems).

I have a radiobuttonlist in a details view. Databinding is happening in PageLoad (if not IsPostback), after a details view item is inserted, edited and upon clicking cancel when in edit mode.Everything works well except when clicking cancel which for some reason the radiobuttonlist appears as empty. The code is surely working because up till OnPreRender the radiobuttonlist contains the required items. However OnRender the list appears as empty.

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#?

I've created a templated user control by following the example on the microsoft support pages. I won't post it all but the important part of the CS file looks as follows:
[Code]....
I'm not sure if the whole _CurrentDataItem business is required, I don't think so.The problem I've got, is that I've tried nesting it inside a FormView control so I can use it to display a record from a database. My ASPX looks like this:
[Code]....
Now, the bound properties (TitleText and TitleSubText) bind correctly, but the nested / template content is blank when the page loads. I'm not sure if this is something to do with the order in which everything is loaded or because I'm missing some code in the SimpleTemplate to get it to bind (etc.).

I have a SQL table containing a list of questions which admin users can add new questions too as and when they feel necessary.
I have a web form with a Repeater which displays these questions next to a checkbox and a textbox. When the user clicks the checkbox or the enteres data textbox I want to click and update button and store this data in a different table.
My current thinking is that this would go into a table with 30 bit fields for the checkbox values (c1-c30) and 30 text fields for the textboxes (t1-t30).
This would allow the admins upto 30 questions in the database at anyone time.
The question is how do i bind the controls in each row of the Repeater to its corrosponding SQL database field i.e row1 t1 and c1, row 2 t2 and c2 etc.
Code:
Protected Sub Repeater1_ItemDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.RepeaterItemEventArgs) Handles Repeater1.ItemDataBound
Dim i = 0
Dim item As RepeaterItem
Dim checkBox As CheckBox = e.Item.FindControl("CheckBox5")

I'm trying to implement an ASP.NET DataBoundControl that supports two-way databinding. Unfortunatelly I can't find any documentation on how to do this on the web and even Dino Esposito in his ASP.NET 2.0 Advanced Topics only handles one-way databinding (also the contact form on his blog isn't working). Can anyone provide me with documentation or samples on how to do this?

I've got a FormView control for which I'm Viewing, Inserting and Updating to a MS SQL Database.
Instead of adding a SqlDataSource control to the page, I've created it in the code behind and declaring the properties/attributes for it during Page_Load.
At the moment, everything is bound and working fine, but I'm having an issue Databinding to the child controls in my FormView with parameters set in the code behind.
This is where I'm at.

So, I need to be able to bind the DS.InsertParameters.Add("PageTitle", ---) with the txPageTitle control in the Insert Template, same with the PageURL to txPageURL. Is there any easy way to do this from the code behind? I can't seem to find a way to add a parameter without needing to assign it a value.

Bringing back to life an old post that I dont believe ever got solved: http://forums.asp.net/t/1562245.aspxThis may be an old thread .... but no answer was ever given ... and I too have a radio button list and DDL and am stuck in the EXACT same place. If I check one of the two data bound radio buttons, the DDL should repopulate with a different set of results. This works just fine EXCEPT .... the DDL cannot be databound. If I set SELECTEDVALUE of the control to a bind I get this error:Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control.I have followed the advice on this page from various users, all to no avail....surely this can be done, and I assume quite simply. Anyone know the answer?

I recently added a repeater control to a page
<asp:Repeater runat="server" Visible="true" ID="repeaterApp" > </asp:Repeater>
When I go to the page_load event in the codebehind, I can't seem to find this control at all. No intellisense whatesover. I've tried renaming, closing the solution, even changing the codebehind directive at the top of my aspx page to "codefile".

I am trying to build a repeater dynamically through the code behind. I found this code on the microsoft site:
Protected Sub Page_Load(ByVal sender As System.Object, _
ByVal e As System.EventArgs) Handles MyBase.Load
Repeater1.HeaderTemplate = New MyTemplate(ListItemType.Header)
Repeater1.ItemTemplate = New MyTemplate(ListItemType.Item)
Repeater1.AlternatingItemTemplate = _
New MyTemplate(ListItemType.AlternatingItem)
Repeater1.FooterTemplate = New MyTemplate(ListItemType.Footer)
Repeater1.DataSource = New String() {"one", "two", "three", "four"}
[Code]....
So this code works without throwing any exceptions, but what I would like to do is accessing the DataSource inside of Sub InstantiateIn(). I know you can access the DataSource in the front end using DataBinder.Eval and Container.DataItem, but is there a way to access the data during the InstantiateIn() Sub?
Or if there is another way to do this i'm up for trying that as well. Essentially I am trying to avoid writing asp.net code, instead I would rather write everything in vb (code-behind)

Let me try to explain my situation. I have a database table which contains, among other things, a boolean column called PermissionSlipRequired. I have a repeater on my page, and before each row in the database is shown in the repeater, I want to use my code behind to check the value of PermissionSlipRequired. Based on whether the value of PermissionSlipRequired is true or false, I want to change the text of a literal within the repeater. That's a real mouthful; hopefully some markup and code will clarify. Here's my repeater:

Here is what I've been able to come up with for my code behind. Needless to say, this code doesn't work.

After much research, no solution can be found to do what I want by combining these two controls. Currently, I have a repeater control which, in page_load, takes the querystring and queries the database accordingly, puts the resulst in a datatable, and binds the datatable to the repeater. Everything works fine, no problem there. It's just that I have many columns coming from the query and there are many rows as well. So, I thought it would be easier to incorporate the accordion, so that the header of each accordion pane would show some unique fields (name, whatever...) as the header, and the rest of the many fields in the content. This way, there would be many closed accordion panes showing the name from the row returned. If the pane is clicked, the pane would open and show the rest of the results.
The problems I've had are that the repeater is not accessible from the code behind if it is inside the accordion. But I'm sure I wasn't doing it right anyways. I'm just trying to have an accordion that has as many panes as there are results from a datasource. If there is something other than a repeater that you can suggest, or the correct way to incorporate the repeater in the accordion to do what I want, suggest whatever! I just need to format how the results display how I want, unlike a gridview (I used tables in my normal repeater, and that worked fine, I just need to get that repeater to work inside of the accordion).
(and I know this isn't the section to ask about the accordion, but what is the AccordionExtender? It's not in the toolbox, and I can't find much online. It won't be recognized by Visual Studio, so I don't know what to do. If I could get that, I feel like it could solve my problem, as I found a possible solution online) I don't need to post my code, as it's a simple repeater, and trying to integrate it within the accordion isn't working no matter which way I try since I can't DataBind() in the codebehind. And yes, I tried to FindControl within the accordion but it wouldn't find the repeater.

I have a repeater which has it's data bound in the code behing. I want it so that as each row is written out I can check the data and if a piece of information stored in the database exists, I can then do something (format the text in a different manner). So far I have this in my code behind:
