Forms Data Controls :: Paging Repeater Control In Databinding?
May 3, 2010
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 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 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 am trying to experiment with things as a beginner and want to use paging in Repeater Control. Since Repeater control is light weight, I want to use that. I have heard of two methods: PagedDataSource class and the other that I dont remember. I wanted to attempt both of them. How do I proceed?

I'm trying to extend the GridView control to enable sorting and paging for any situation.
When using my control I am fetching data from a database and filling a DataSet with it, then binding the GridView upon every page load. My first question would be, is this the correct approach?
To sort the GridView I am overriding the OnSorting method which stores the sort expression and direction in the ViewState, then creates a DataView and utalises the Sort method to sort the underlying data. It then sets the Data Source to this DataView and rebinds the GridView.
Paging is handled by OnPageIndexChanging which simply sets the PageIndex property and again rebinds the GridView.
My problem is; when any control causes a postback my GridView is no longer sorted, presumably because it is persistently rebound. If I don't rebind it then the GridView is empty on postback since the data isn't automatically stored in the ViewState. I have considered saving the data source in the ViewState but I would assume that this is bad practice for large amounts of data? - also DataViews are not seralisable.
The only solution I can think of currently is to override OnDataBound and sort the data every time. This results in a double sort when paging triggers a postback which seems inefficient. Code illustration of this below,
[Code]....
I'm looking for the cleanest 'best practice' solution as this is a learning exercise more than anything else.

I have a need to add a new report to my page, the differnent parts of the page are all using a objectdatasource to populate the data. The new report because of all the data being returned i have started to use a repeater and a table in the ItemTemplate. Just binding the objectdatasource to the repeater works fine, but returns all the records and causes the page to be very long. I found this link for adding paging to repeater, but its setup different than what i have

Is there any way to use what i have already and add paging to the repeater?

URL... I'm trying this approach and I like it, It is what i was finding. customize the function he wrote to populate the pager control:
private void PopulatePager(int recordCount, int currentPage)
{
double dblPageCount = (double)((decimal)recordCount / Convert.ToDecimal(PageSize));
int pageCount = (int)Math.Ceiling(dblPageCount);
List<ListItem> pages = new List<ListItem>();
if (pageCount > 0)

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")
