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
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>
rptOuter_ItemCommand
when i will use it how this code can be written...
I'm having some real problems trying to do this. In simple, a table shows a list of rooms with details of the room in each column, extracted from a database. The there is a button in the repeater, which is supposed to tell me what I clicked on in a new label. However the OnItemCommand just doesn't seem to be working.
[Code]....
Right now I'm just trying to get it to work, so that when I press the button, it causes the label to say "It works". But it just doesn't want to work.
<asp:Repeater ID="rpProducts" runat="server" OnItemDataBound="rpProducts_OnItemDataBound" OnItemCommand="rpProducts_OnItemCommand">
View 7 RepliesI am using a repater whose item template is having a dropdownlist. Now i want to access that dropdownlist from a button click event. Here is the code iam using :
protected void btn1_Click(object sender, EventArgs e)
{
foreach (RepeaterItem item in rptWord.Items)
{
DropDownList ddl1 = (System.Web.UI.WebControls.DropDownList)rptWord.FindControl("ddlWord");
}
}
But m getting ddl1 as null. For this i created a function which is as follows:
public void myFunction(object sender, RepeaterItemEventArgs e)
{
foreach (RepeaterItem item in rptWord.Items)
{
DropDownList la = (System.Web.UI.WebControls.DropDownList)e.Item.FindControl("ddlWord");
}
}
using this function iam able to access the repeater but i guess its not possible to call this function on button click event .
I 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?
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.
I need to access a control inside a repeater and change its properties. To enable it or not. I got an erorr message Object reference not set to an instance of an object. Here is my code inside a method. protected void
rptCAP_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
LinkButton lnDel = (LinkButton)rptCap.FindControl("lnkDelete");
lnkDel.Enabled = false; //<<<<< this is where the error occur
}
The name of the repeater control is id="rptCAP"
My repeater:
<asp:Repeater ID="rptrContacts" runat="server" OnItemCommand="rptrContact_ItemCommand" >
<div ID="itemTemplate>
<ItemTemplate>
<%# Eval("Name") %>
<%# Eval("Email") %>
<asp:LinkButton ID="lbtnEditContact" runat="server" CommandName="Edit" Text="Edit" CommandArgument='<%# Eval("ContactID") %>' />
<asp:Label ID="lblUpdateConfirm" runat="server" Text="Update Confirmed" Visible="false" />
</ItemTemplate>
</div>
<div ID="editTemplate runat="server" visibility="false">
Update your Info:<br>
Name: <asp:TextBox ID="txtName" runat="server Text="<%# Eval("Name") %>"/> <br>
Email: <asp:TextBox ID="txtEmail" runat="server Text="<%# Eval("Email") %>"/><br>
<asp:LinkButton ID="lbtnUpdateContact" CommandArgument='<%# Eval("ContactID") %>' CommandName="UpdateContact" runat="server" >Update</asp:LinkButton>
</div>
</asp:Repeater
and code for ItemCommand:
switch(e.CommandName)
{
case "Edit":
//make editTemplate div visible
HtmlGenericControl divEditContact = (HtmlGenericControl)e.Item.FindControl ("divEditContact");
divEditContact.Visible = true;
break;
case "Update":
Employee updateEmployee = new Employee
{
employeeName = txtName.Text:
employeeEmail = txtEmail.Text:
}
updateEmployee = API.UpdateEmployee(updateEmployee);
//display lblUpdateConfirm visible to True
// so user sees this confirm messge in the newly updated ItemTemplate
}
How can I access my lblUpdateConfirm and turn its Text state to visible from inside the ItemCommand, so that when the user sees the newly updated ITemTemplate, the label is showing the "Update Confirmed" message?
i want to add and access to placeholder in a repeater control. for example,
[Code]....
how can i acces to placeholder, on codebehind. i couldn't acces with it's id.
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.

I have a user control (this has a label to display question and a radio button list to show options).
I am using this user control inside a repeater to display all the questions with their options.
In my repeater page I am not able to capture SelectedValue of radio button list.
protected void Repeater1_ItemDataBound(object sender, RepeaterItemEventArgs e)
i have simple repeater control on my page:
<asp:Repeater id="Repeater1" runat="server" DataSourceID="SqlDataSource1">
<ItemTemplate>
<asp:TextBox id="txtBox1" runat="server" Text='<%#Eval("attributename") %>'></TextBox>
<ItemTemplate>
</Repeater>
I'm bounding data to repeater control by using SqlDataSource Control
bounded data is something like this:
attributeid attributename
1 color
2 size
How can I get access to attributeid values in Repeater control's ItemDataBound event handler,
I tried to use DataBinder.GetPropertyValue(container,"attribuetid"), but I can't set container, am I doing right, or maybe I should use another approach.
got an example of a repeater inside a repeater (dataBound) code behind?
View 3 RepliesI have a user control that displays a shopping cart in an ecommerce application.
The main cart display is a repeater that renders as a html table. In one of those table columns, there is another repeater to display people associated with the products int he cart (it's a repeater in case there is a line item >1 with multiple people).
I've added an ImageButton that I want to use to change the person associated with the item. At first, when I'd click on it I was getting this error:
Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.
So as an experiment I disabled EventValidation on the page (not the control it's self) and now I do not get an error, but I also do not ever hit the breakpoint I set in the innermost repeater's ItemCommand event.
So I wonder how I might do this without disabling EventValidation, because this control will show up on multiple pages and we don't want to edit them all. Also, I'll need to know not only the repeater containing the control's row that the event came from but also the row index of the repeater containg this one. Is this possible?
I have repeater in which I have 2 hyperlink in the footer of the repeater and I want that the hyperlink can navigate from the page_load
View 2 RepliesI am using a repeater to build a custom table. However, I can't figure out how to make the table show subtotal if the next rows tour does not match the previous rows.
Something similar to that.
row1 tour1
row2 tour 1
tour1 subtotal
row3 tour2
row4 tour2
subtotal
total
[code].....
but this shows all the data in the nested repeater not the ones that match the parentrepeater fields for example tour,theme,dep7 should match in the child repeater
I'm so confused I wasn't even sure what to make the title so that it would make sense.
Here is what I have:
[code]...
I have links at the top of the page that are the letters A-Z. What I want to do is click on one of the letters, then show only the div IDs that start with that letter. I can't figure out how to do this since I'm dynamically creating the ID names. I had it set up nicely with Javascript and CSS, but the function call was inside the repeater. The layout is changed now, and I don't understand how to make the div ID available outside the repeater.
I am using Nested Repeater repeater1 and repeater2 in my project . one button is there inside repeater2 but i cant use that button using e.commandname
so how to use that button and how to write code on it.
what changed do I need to make to my code for it to achieve what I'm after.
At the moment I am getting a "cannot cast to type" error message with the below code.
I have also tried calling the ItemDataBound method in with the parent repeater tags and had no errors but when I clicked on the button it would just move back to the top of the page and would not hide or show any data. Also I have made the div style to none but the first record still shows its child but the rest don't.

I'm using a linq group by query (with two grouping parameters) and would like to use the resulting data in a nested repeater.
var dateGroups = from row in data.AsEnumerable()
group row by new { StartDate = row["StartDate"], EndDate = row["EndDate"] };
"data" is a DataTable from an SqlDataAdapter-filled DataSet. "dateGroups" is used in the parent repeater, and I can access the group keys using Eval("key.StartDate") and Eval("key.EndDate").
Since dateGroups actually contains all the data rows grouped neatly by Start/End date, I'd like to access those rows to display the data in a child repeater. To what would I set the child repeater's DataSource? I have tried every expression in markup I could think of; I think the problem is that I'm trying to access an anonymous member (and I don't know how.) In case it doesn't turn out to be obvious, what would be the expression to access the elements in each iteration of the child repeater? Is there an expression that would let me set the DataSource in the markup, or will it have to be in the codebehind on some event in the parent repeater?
I have set up an asp repeater to go through and display a list of people based on input parameters. Within that repeater I have a repeater that displays specific details about each person. No problem so far.
However, my requirement is that I only display the names, with a plus/minus sign to the left of the name. Clicking on the plus sign will expand that person's information to show the details. Clicking the minus sign will collapse the detail info.
I have a panel set up within my primary repeater that encompasses the secondary repeater.
Here's the beginning of the code:
[Code]....
For the solution, I cannot use any postback methods, because this is all working through ajax. The solution need to be implemented in the asp.net code. I have a List<WebPage> that contains a list of Links (List<Link>) and I need for all the links to bind repetitive information such as page title, id, url. Here is my current repeater.
<div id="result">
<asp:Repeater runat="server" id="results">
<Itemtemplate>
<asp:Repeater runat="server" datasource='<%# Eval("Links") %>'>
<Itemtemplate>
<tr class="gradeX odd">
<td><%# Eval("Id") %></td> //property of WebPage (part of results repeater)
<td><%# Eval("Title") %></td> //property of WebPage (part of results repeater)
<td><%# Eval("Url") %></td> //property of WebPage (part of results repeater)
<td><%# Eval("URL") %></td>//Property of Link
<td><%# Eval("URLType") %></td> //Property of Link
<td><%# Eval("URLState") %></td> //Property of Link
</tr>
</Itemtemplate>
</asp:Repeater>
</Itemtemplate>
</asp:Repeater>
</div>
of course this doesnt work, how can i do this?
