Using ControlParameter With TextBox Inside Repeater?
Nov 11, 2011
Inside the OnItemCreated event (of the repeater), I get the ID of the textbox that I want to bind to the ControlParameter. I realized that using the ID alone was not working. I get a message saying something like "can't find txtBoxName in ControlParameter". I read somewhere that if I view the page source of the browser, then use the value in the Name attribute of the textbox (for the controlId property of the controlParameter), it works. But I also noticed that when I use a textbox outside the repeater, I could just use the ID of the textbox (without having to use page source to get the name, which is different from the ID in the aspx page, of the textbox).

I'm using an accordion control with a textbox to get data that I'll use later to get values for a ObjectDataSource, that use the data of the textbox as ControlParameter.
my problem is that I'm getting a 'Not found control error...' because the textBox is inside the accordion how can I reffer the control into my ObjectDataSource?
Here is a reduce example of my code.

First of all i have placed my repeater inside a asp:updatepanel. I have tested to set a value where i know the specific row id. This works but i dont know how to do this when i dont know the specific id and i want to be able to update multiple rows at the same time. I have bound my linqdatatable to a repeater. This table contains multiple rows, so the repeater returns a dynamic count of row. I want to be able to edit one of this columns through a textbox that is generated in my repeater. How can i do this ? I guess it has something to do with ItemDataBound ? But i dont get this to work.

I have an ObjectDataSource with a number of parameters. These parameters are binded in my FormView EditItemTemplate and the ItemTemplate. My Stored Procedure column names in my ItemTemplate are different to the Bind properties used in the EditItemTemplate. This is obviously throwing an exception when I update a record.
Instead of using Bind("Columne Name") in my EditItemTemplate how do I use a ControlParameter to reference a TextBox in the EditItemTemplate?
I may be wrong but I'm trying to use the PropertyName=Controls but i do not know how to reference the Textbox in the EditItemTemplate.

I 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?

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.

Inside a repeater there's a list of addresses ..when address link button is clicked, the address is shown inside of text boxes above repeater with all text boxes greyed out and an Edit button is rendered on the page OUTSIDE the repeater and below the text boxes..Now how do I edit this address ?
I need the AddressID of the address that has been clicked inside the repeater...
when Address link is clicked,DisplayAddress command event is fired inside of repeater's ITemCommand so what I did was assigned "AddressID" generated(when Adress link was clicked inside repeater) to a globally decalred string variable and tried to use that inside my Edit Button's click event so as to fill the Datasource(Method used to fill data source requires AddressID) and do stuff...didnt work

In my UserControl, Im trying to update a updatepanel that is inside a repeater like this:
HTML-Markup
<asp:UpdatePanel ID="updDocumentQuickView" runat="server" UpdateMode="Conditional">
<ContentTemplate>
<asp:Repeater ID="repFolders" runat="server"
[code]...
The end result I get is that updDocumentQuickView is the UpdatePanel that gets updated, and not updFiles. If i wrap an UpdatePanel around lnkFolder, then that UpdatePanel gets updated, with the same C# code. Ive checked what kind of data that are sent back with fiddler, and the wrong UpdatePanel is sent. Im getting the correct RepeaterItem, and both repFiles and updFiles are found. What do I miss to get the right UpdatePanel to get updated?
UPDATE
Hawxby solution solved the problem with updDocumentQuickView getting updated, thanks for that. But im still having problems with updFiles sending nothing back. Some further testing, with putting literals inside updFiles and working, tells me that theres something with repFiles that isnt returned. repFiles does have data that is bounded.
FINAL SOLUTION
repFiles.Visible were set to false in repFolders_OnItemDataBound, no wonder it didnt show.

I have a HTML table that is built with a repeater. Sometimes the table has 5 rows, sometimes it has 8 rows.
It was easy to add the header rows.
<asp:PlaceHolder runat="server" ID="additionalHeaderColumns" />
In code behind I added controls (htmlheadercells) to the contentholder:
Dim tableHeaderCell As New TableHeaderCell()
tableHeaderCell.Text = "Test"
additionalHeaderColumns.Controls.Add(tableHeaderCell)
When I try to do the same in the databound event for each row I get an errormessage that tells that its not possible to put asp:PlaceHolder inside the row. it expects tablecells.

I'm doing a webpage with a search that brings a lot of information from MSSQL. What I did is a stored procedure that return only the page to be seen on the website. Right now I'm working on the paging as I need to show something similar than google. If you are at page 1 they show first 10 pages and if you are at page 19 they show since page 9 to 28. I think the best option to show the page numbers is using a linkbutton inside a repeater. The problem that I have now is that I do not know the best way to take the page number at postback.
Doing a quick sample I assigned an ArrayList to repeater.datasource:
<asp:Repeater ID="Repeater2" runat="server">
<ItemTemplate>
<asp:LinkButton ID="LinkButton1" runat="server" CommandArgument="<%# Container.DataItem %>"><%# Container.DataItem %></asp:LinkButton>
</ItemTemplate>
</asp:Repeater>
<asp:LinkButton ID="LinkButton2" runat="server" CommandArgument="4654">Test #1</asp:LinkButton>
At my Default.aspx.cs file I have the next code
protected void Page_Load(object sender, EventArgs e)
{
if (this.IsPostBack)
{
string x = LinkButton2.CommandArgument;
//string y = LinkButton1.CommandArgument;
//I know this line will not work since the Linkbutton1 is inside the Repeater.
}
What Shall I do to make it works? Does anyone has a better solution for this paging?

Simply, I have an anchor inside a repeater that triggers on click a javascript function, which sets the innerHTML of a Div to some content.
trying this outside a repeater did work! but if I tried to implement the same code in the repeater's item template, it won't work!
NOTE: I think I need to access the repeater first then access the Anchor inside it! but I don't know how to do it
For further illustration:
JavaScript Function:
function show(ele, content) {
var srcElement = document.getElementById(ele);
if (srcElement != null) {
srcElement.innerHTML = content;
}
}
The repeater's code:
<asp:Repeater ID="Repeater1" runat="server" >
<ItemTemplate>
Name : <%# Eval("name")%>
<DIV ID= "PersonalInfo1" runat="server"></DIV>
<A id="A1" href="#" runat="server" onclick="show('PersonalInfo1','Address : ')">More...</A>
</ItemTemplate>
</asp:Repeater>
PS: THE POSTED CODE ISN'T WORKING IN THE REPEATER!

I have a user control which is used to display search results. The HTML for each result displayed will vary based on the type of result being displayed: "contacts" are displayed in one way, "news articles" are displayed in another, etc. There are around 10 different types of results that are all marked up differently when they get to HTML — so I need around 10 or so different templates for individual results that I can choose between based on the current item being displayed.
I'm using an asp:Repeater to display the results, but I don't know how to select the appropriate template within the asp:Repeater <ItemTemplate>. Ideally I'd like the ASP to select the appropriate template to use based upon the object type being passed in via the searchResultsRepeater.DataSource — but unfortunately I can't use switch on type (see this blog entry for C# switch on type). I can however just pass through an enum value for the type of result being displayed.
In the backend C# code I have an abstract inline SearchResult class, and children of that class like ContactSearchResult, NewsArticleSearchResult, etc. The searchResultsRepeater.DataSource would then be bound to a List<SearchResult>. Each SearchResult contains a ResultListingType type field which gives the type of the listing to be displayed.
Attempt 1: using control flow inside the ASP itself
My first attempt was something like this:
<asp:Repeater ID="searchResultsRepeater" runat="server">
<ItemTemplate>
<div class="item">
<% switch (DataBinder.Eval(Container.DataItem, "type")) { %>
<% case ResultListingType.CONTACT: %>
<p><%# DataBinder.Eval(Container.DataItem, "firstName") %></p>
<p><%# DataBinder.Eval(Container.DataItem, "lastName") %></p>
<% break; %>
<% case ResultListingType.NEWS: %>
<p><%# DataBinder.Eval(Container.DataItem, "newsHeadline") %></p>
<p><%# DataBinder.Eval(Container.DataItem, "newsDate") %></p>
<% break; %>
<% Case AnotherTypeOfListing1: %>
<% Case AnotherTypeOfListing2: %>
<% Case AnotherTypeOfListing3: %>
<% Case AnotherTypeOfListing4: %>
<% Case AnotherTypeOfListing5: %>
<% etc... %>
<% } %>
</div>
</ItemTemplate>
</asp:Repeater>
Unfortunately, this doesn't work:
"switch" and "if" both give "invalid expression term" inside the <%# ... %> brackets.
"Container.DataItem" gives "the name "Container" does not exist in the current context" inside <% ... %> brackets.
Attempt 2: setting asp:PlaceHolder's to Visible = False
I found something that looked useful at how to change the ItemTemplate used in an asp:repeater?. I then tried something like:
<asp:Repeater ID="searchResultsRepeater" runat="server">
<ItemTemplate>
<div class="item">
<asp:PlaceHolder ID="newsResultListing" runat="server">
<p><%# DataBinder.Eval(Container.DataItem, "newsHeadline") %></p>
<p><%# DataBinder.Eval(Container.DataItem, "newsDate") %></p>
</asp:PlaceHolder>
<asp:PlaceHolder ID="contactResultListing" runat="server">
<p><%# DataBinder.Eval(Container.DataItem, "firstName") %></p>
<p><%# DataBinder.Eval(Container.DataItem, "lastName") %></p>
</asp:PlaceHolder>
</div>
</ItemTemplate>
</asp:Repeater>
In my ItemDataBound event I did:
Control newsResultListing = e.Item.FindControl("newsResultListing");
newsResultListing.Visible = false;
Control contactResultListing = e.Item.FindControl("contactResultListing");
contactResultListing.Visible = false;
switch (item.type)
{
case ResultListingType.CONTACT:
contactResultListing.Visible = true;
break;
case ResultListingType.NEWS:
newsResultListing.Visible = true;
break;
default:
throw new Exception("Unknown result listing type");
}
Unfortunately this doesn't work because ASP seems to still be running the contents of the PlaceHolder even after I set Visible = false. I get the error "DataBinding: 'usercontrols_ResultsListing+ContactResultsListing' does not contain a property with the name 'newsHeadline'" — i.e. the newsResultListing PlaceHolder is still looking for the "newsHeadline" field, even though that field doesn't exist for the result listing type being displayed.
In fact I've tried a quick test throw new Exception("e"); in my ItemDataBound, and it looks like the "DataBinding" error is thrown even before control flow gets to the ItemDataBound method, so there's really nothing I can do in there to avoid this error.
I suppose I could add every single field to the parent class and leave most of them null in my children, but that seems really ugly.
Is there a way to make this work, or an easier way to vary my ItemTemplate based upon the type of Container.DataItem I'm currently iterating over? I'm very new to ASP so there's likely something simple that I've missed.

I have a drop down list inside a repeater on a screen. I have no problems populating the list with all of the options at the time of binding. Everything works out fine EXCEPT the load time.
All of the options are there so it's fine. But my users would like me to fill the drop down list with the values at the time they click on the drop down list.
The repeater itself is inside an AJAX Update panel.
So I am trying to figure out how would I fill the drop down list with the actual values when they click on the drop down list inside the repeater inside the update panel?
