Inside repeater's itemtemplate I have a Panel server control.I need to assign special Id for it, because I need to work with some javascript functions that use this Id.
In repeater ItemDataBound event I have this:
pnlButtonsPanel.ID = pnlButtonsPanel.ID + DataBinder.Eval(e.Item.DataItem, "ID");
But this solution is not good because after a postback the page is re -rendered and I lose the new ID. (And I don't want to rebind repeater after every postback)
I tried to set the ID on aspx page like that:
<asp:Panel id='<%# Eval("ID") %>'
and some other variations but always get compile errors.
I am having big trouble with this issue, getting a message from IE that a script is being running for a long time and asking me to stop it myself.
The HTMLEditor seems to be uncomptible with this one.
I am also getting a very weak performance when adding this Ajax control.
I think this control is very heavy, but I'm not sure. If I am not wrong, this post I'm writing is inside the same control and I can see it takes time to load it in my page.
I have this code
protected void Page_Load(object sender, EventArgs e) {
if (!IsPostBack) {
ArrayList olist = new ArrayList() {"visible", "invisible", "visible", "visible", "visible", "invisible", "visible", "visible", "invisible"};
for (int i = 0; i <= olist.Count-1; i++) {
if (olist[i].ToString() == "visible" ) {
[Code] ....
I want to hide the button if records found "invisible".
The output must be like this:
-----------------------------------------------------------------------------------------------------
Another question is
I want to get the button index value inside the repeater row, when the user click the button the index value display one Label3
void repbtn_Click(object sender, EventArgs e) {
Label3.Text = "The button item index that clicked in the repeater is: "; // + irepeater.Items. ;
}
I have something like this:

This does NOT work. What's wrong here?How do I accomplish my goal? I MUST use the Button1_Click event for this one.
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 am using a repeater control and i want to use one more repeater control inside the existing repeater control .Â
Like this:
<asp:Repeater ID="Repeater1" runat="server">Â Â Â <HeaderTemplate>Â </HeaderTemplate>Â Â Â Â Â Â
<ItemTemplate>
<!-- start child repeater -->    Here I want to use one repater control     <!-- end child repeater -->
</ItemTemplate>
</asp:Repeater>
I am new to Repeater and DataBinding
In PageLoad, I have
var photos = from p in MyDataContext.Photos
select new {
p,
Url = p.GetImageUrl()
};
repeater1.DataSource = photos;
repeater1.DataBind();
In the Repeater control, I have
<ItemTemplate>
<% Photo p = (Photo) Eval("p"); %> <!-- Apparently I can't do this -->
...
<asp:TextBox runat="server" ID="txtTime" Text='<%= p.Time == null ? "" : ((DateTime)p.Time).ToString("dd/MM/yyyy HH:mm:ss") %>' />
...
</ItemTemplate>
But that is wrong.
What I need is to get the Photo object in ItemTemplate so I can do things with it (eg. to display the time as in the second line in ItemTemplate above). Is it even possible to do this in a 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

i have 2 time selector in repeater now how to save value of  TimeSelector in database
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 have a repeater with select html inside the item template.
I could not use dropdown list as it does not support so i had to build select with inside a repeater.
On button click i want get the value of the selected item.
the inside the repeater does not have runat=server.
How can i do this?
I have a repeater bound to a datasource that servers as a list of birds. When the user clicks an item in the list the bird's image is displayed on the page. I want to change the background color of the item that is currently selected in the OnClick handler for the main item in my repeater's ItemTemplate.
I have changed the styling of controls prgrammatically before and it worked fine but in those cases i used the ID of the control to directly access it in my code behind file. But since this is some arbitrary item in a repeater I don't know it's ID at runtime, all I have is the sender object passed to the control's OnClick handler. So in my code behind file, I tried casting the sender object passed to the OnClick handler to the appropriate type and used Style.Add("background-color", highlitColor) but it failed to change anything.
I had a thought - maybe this sender object gets passed by value so all I did was change the Style of a COPY of the control item.
If this is indeed my problem, how do I start with a casted sender object in an event handler and get a reference to the actual control in order to change it's Style?

I have a repeater control that is getting exported to excel. Well excel will no longer show the data that was in the textboxes. I've read the article on exporting a gridview having the same problem and how you replace the texboxes with literal contrls.

Button inside the repeater not firing
i have a repeater that displays data from a SQL Server Database. I also want to display an int from the database for the specific item and allow the user to add 1 to the value of that int by clicking a button (almost like a pole). It would work similiar to a 'like' button on Facebook.e.g.

Click to like (5 likes) [code]....
