On my asp.net page, I have several DropDownLists. I also have a Repeater.
In the ItemDataBound event I want to get the value of these DropDownLists, to change the data in the Repeater. The SelectedValue of these DropDownLists is empty. But after the ItemDataBound, the Page_Load is executed. There I can get the value of these DropDownLists.
Is there a solution to get the value when the ItemDataBound is executed.
I am using a repeater control and i want to use one more repeater control inside the existing repeater control .
Like this:
<asp:Repeater ID="Repeater1" runat="server"> <HeaderTemplate> </HeaderTemplate>
<ItemTemplate>
<!-- start child repeater --> Here I want to use one repater control <!-- end child repeater -->
</ItemTemplate>
</asp:Repeater>
I have a method that needs to find the repeater control to add data. I try the code below, but keep getting an error "not set to an instance of an object."
hyp = (HyperLink)Repeater1.FindControl("orderID");
hyp.ID = docName;
So I currently have a aspx page that shows details for any single staff member, and the page is setup with mostly ASP labels. I have a subroutine called "getstaffdata" that populates the page on load (via subroutine).
I would like to convert this to a page that shows details on one staff member, or many staff members, one after another. So I thought of using the repeater control, but I'm not sure how to convert the page over. The staff userids are passed via query string, but I'm just confused on how to do the datasource for the repeater control.
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 repeater control in my page ,and it contains Questions and its options in check boxes . i want to store that information if user refresh the page
View 1 RepliesI want to bind parent repeater item index in child repeater control using inline code not code behind side.
For example
[Code]....
Edit: I have a working solution already - I would just like to know why my original attempt didn't work. My original attempt is the code below.
I'm using the approach I found here:[URL] 306154 to implement a nested Repeater. Each parent item has one or more children items (the point of having the nested Repeater) with a dropdown horizontally aligned to each child item. In an effort to re-use the nested part of the Repeater I wanted to develop that piece as a user control but couldn't get it to work. I am wondering if it is even possible and if so how?
Here is my user control apsx:
<asp:Repeater ID="NestedRepeater" runat="server">
....
<ItemTemplate>
<tr class="text" id="RepeaterItemRow" runat="server">
<td>
<%#DataBinder.Eval(Container.DataItem, "Name") %>
</td>
<td>
</td>
<td>
</td>
<td>
</td>
<td>
</td>
<td>
</td>
</tr>
</ItemTemplate>
And here is my code behind for the user control. I noticed when I debugged NestedDataSource was null even though in the parent page load the data is there:
public DataSet NestedDataSource
{
get;
set;
}
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
NestedRepeater.DataSource = NestedDataSource;
NestedRepeater.DataBind();
}
}
In the parent Repeater in the `<ItemTemplate> I have:
<asp:RepUC ID="NestRep" runat="server" NestedDataSource='<%#((DataRowView)Container.DataItem).Row.GetChildRows("nestedrel") %>'>
And finally the page code behind:
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
BuildWBS();
}
}
private void BuildPage()
{
DataSet ds = new DataSet();
ds = DataAccessLayer.GetData("System");
ds.Relations.Add("nestedrel", ds.Tables[0].Columns["Id"], ds.Tables[1].Columns["ParentId"]);
ParentRepeater.DataSource = ds;
ParentRepeater.DataBind();
}
The page loads but nothing relating to the repeater appears on the screen. So, can you see anything wrong with what I have? Is the way I tried doing this even possible?
lets say I want to make a label of repeater1 visible in repater2's ItemCommand() method..
e.Item.FindControl("rpt1Label").Visible=True;
is not working..how else do you do it ?
[EDIT]
changed that to repeater1.FindControl("rpt1Label").Visible=True;
This is throwing object reference null exception
If I have a custom user control (say, MyCustomControl.ascx) which contains a number of other controls including a repeater, is there any way to expose that repeater's templates as templates for MyCustomControl?
For example, I would want to be able to do this:
[code]....
There could potentially be more than one repeater or other templated controls within the parent control, in which case I would like to be able to expose all of those templates for all of the controls in the same way.
My first thought was to simply expose the repeater's templates as ITemplate properties on MyCustomControl, but that didn't work since there's no (obvious) way to access the repeater's DataItem from the templates doing it that way.

This has got me stumped. I am trying to find a checkbox in a dynamically loaded asp.net Repeater template. The template works fine and the databinding is fine and everything displays fine but I can't find the control!

I have nested a repeater control in Gridview. Right now it is showing gridview rows and repeater header for every case(whether data is there or not for that particular grid view row in the repeater control). I want to hide the gridview row and repeater control header when there is no data present for that particular gridview row. That case I handled at code level by filtering the resulted data table.
Now the another problem I am facing: I have allowed the paging on the gridview i.e. pagesize 3. When page loads it works fine, but when I go to page 2 then it generates following error: Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index
Below is the code to fill the grid, paging and fill repeater on rowdatabound event of grid.

View 3 Replieswhich is the best asp.net control to allow a user to enter data into a table and then save it. Then the codebehind can iterate the the rows and save each row to the database. Then load the table when the user wants to see the data. Would this be the repeater or Gridviewcontrol?

I have a repeater which nests one or more custom control instances. Each custom control instance has a drop down and a button called "Update".
This all works fine when JS is on.
However with JS off, I get the "Invalid postback or callback argument. Event validation is enabled..." error.
Thinking about this, I imagine the following is happening:
ASP.NET creates ViewState for the page. When the page is posted back, the viewstate should be passed back to the page via the js hooks that ASP.NET puts in place. However, because JS is OFF, this isn't passed back. ASP.NET then flags a mismatch between the ViewState that it expects, and the Viewstate that it receives.
I have a repeater control and everything works great except. . . Every time the form does a post back, which is often, it scrolls to the top (Grrrr). Unfortunately (and apparently) MaintainScrollPositionOnPostback="true" has no affect on the repeater control. I looked on-line and as is customary in .NET there are plenty of "work-around" solutions plenty of which look promising, none of which I could get to work. The most promising solution involved an UpdatePanel and some JavaScript, but that didn't work because it required a second ScriptManager (you can only have one) and I needed the other for my date picker extension. So all I want is the page to stay where it is on callback (I just hate dealing with irate users).Here is the ASP for the repeater:
Code:
<asp:Repeater ID="Repeater1" runat="server" >
<HeaderTemplate>
<table class="formTbl" border="0" cellspacing="2px">
<colgroup>
<col width="75px" />
<col width="75px" />
<col width="50px" />
[code]...
Note: the reason CalculateFootage() is a separate function is because I also call it in the Page_On_Load
