I am trying to find a child control from a repeater control's child control. I have the following structure like a top control is a repeater, below which is a Panel and below this is a DateControl(custom control).
I want to find the DateControl.
<asp:Repeater runat="server"
ID="rptMembers"
<ItemTemplate>
<asp:Panel ID="pnlAddDependent".....
I want to bind parent repeater item index in child repeater control using inline code not code behind side.
For example
[Code]....
What I'm trying to do is find a control within a nested repeater when the OnItemDataBound event is fired on the 'main' repeater.
[Code]....
This has driven me mental! And I've done stacks of web searches and ended up confusing myself even further.
I am trying to find my label control in a repeater and I thought I did this correctly but I came up with an error message:
Compiler Error Message: CS0165: Use of unassigned local variable 'okcEventDate'
Source Error:
[Code]....
Here's my code:
[Code]....
Is it not finding my control? If not, can someone tell me how to find the label control?
I' Trying to find the control i Repeater <Headertemplate> and I got this error "Specified argument was out of the range of valid values.
((Label)Repeater Created. Controls[0].FindControl("lblHeader")).Text = "sample";

[Code]....
Using javascript, I store into a hidden section on the page the IDs of all modified textboxes in my gridview so that I will know which ones need to be updated to the database when the user clicks "save changes". On the postback, I would like to use these textbox control ids to access the gridview row which contains them. Is there an efficient way to search a gridview on a child control id? (I need to do this to get the gridview row datakeys)
View 2 RepliesEdit: 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?

have some Objects, lets say Employee and Role defined as below and I have defined relationships in my database that gives me a list of objects say employees and thanks to my framework each employee object also has a Role object linked via the RoleIDID, UserName, Password, Email, RoleIDRoleID, RoleNameSo in code I can do something like this
Employee emp = dataService_GetEmployeeByID(1);
string RoleName = emp.Role.RoleName;
Now here is my problemI can bind any object in a repeater and it works fine for the first level in my relationship
For instance <%# Eval("UserName") %>
But I need to be able to show the details for my child objects as well (Role) so something like this (which does not work)
<%# Eval("Role.RoleName") %>
I am using a form view control which has two binded textbox. Now at this level it works fine and the textboxes show the values from database. But when i insert a panel inside the form view and move these two textboxes inside the panel, they dont show any values. What could be the reason for this?

How to create Grid view control inside Repeater control.
View 7 Repliesi have a repeater control, with a button in it.
how do i make the button NOT visible on the page_load programaticaly
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.
I have a gridview where I in codebehind add a templatefield
[Code]....
In my update command when i try to find the "Result" textbox I get a null object
[Code]....
In the gridview there is another templatefield "Name" that consist of two boundfields("Firstname" and "Lastname") This column is added in the design phase and not in the codebehind.I don't have any trouble finding these controls using the ID added in the markup
[Code]....My issue is with the result column that I add in codebehind.
I have an object data source control. and to insert the control I add the object to the database then call databing on the gridview the DataSource control is bound to.
My question is - how would I know where the newly added row is? I can'y go by id, because the dbase creates the id.
I'm thinking maybe last data key, but based on the sort that would be accurate.
