AJAX :: User Control With ModalPopup In A Repeater?
Dec 24, 2010
I have a user control that contains a modal popup extender.
I am using the user control inside of a repeater so it could be shown multiple times on a page.
Everything works fine if the repeater only contains one item.
When there are multiple user controls on the page I get the following error:
"Microsoft JScript runtime error: Sys.InvalidOperationException: Two components with the same id 'PosAdjPopup' can't be added to the application."
How do I get my user control to work with the modal popup extender when it will be used multiple times on a page?
Can I keep the modal popup extender in the user control or do I have to put it on my aspx page and trap the event on the button click?

I am quite new to asp.net. I would like to ask for some advice on how this scenario can be achieved. Here is the problem:
I have a 5 gridviews on my page. In each gridview, I have two important columns. They are SellerID and BuyerID. Because I already have too many gridviews on the page, I want to load a webuser control with a modalPopupExtender when either SellerID or BuyerID is clicked. That is to say if a user select a SellerID, the details information about that SellerID should be loaded with DetailView from the user control and if the buyerID is click, the details information about that buyer should be loaded with another detailview
from the user control as well.
My problem is I do not know how to get the Selected Value from the gridView since the DetailView is in the WebUserControl. One more thing, both SellerID and BuyerID are in the same GridView, so how can we distinguish when a user select a SellerID or vice versa.

I have three modal popups that are working properly because I test it the controls with simple plain text.
I placed a form view and a datalist in the first two modal popups and everything seems to be okay.
I need to place a user control in the third modal popup but everytime I place the user control I get a javascript error for that particular modal popup.
When I copy paste the same modal popup on a blank page and place the user control inside of the panel then the modal popup works perfectly fine.
I basically copy/paste the same code back where the other two modal popups are then I get the same JavaScript error.
The modal popup crashes first on:
this._popupElement.parentNode.appendChild(this._foregroundElement);

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?

I am using a modal popup control which contains an UpdatePanel. There are one combo and few text boxes and Calendar control in it. When I select any item in combobox, then it's selection change event is fired and there iI set the values of other controls and finally I call update method of update panel. Functionality wise it works properly but it takes a time to update the panel.Here combobox contains around five thousands of items. But when it contains 100s of items it works good.

I have found a couple of good topics here in the forum and wanted to see any other extra ideas for this control that I am making and trying to implement. So here is the basic information:
The control is going to display a SQL output in a bunch of label controls. The information is going to be coming from a gridview control where the field is going to be hyperlinked.
So I am wanting to set the "TargetControlID" property to the .ascx page load event.
now what I have found is that I can simply run the Popup.show(); function in the .cs file at the end of the page load, but I still have to place a valid control within the TargetControlID property. As you know, the property cannot be "null" and if I put in the control ID for something that is not valid, then it won't work either. So the only thing I can think of is tying it back to the overall control itself. Then I can always change it on the fly if needed, but I think I would not have to since it would fire on the page_load event...
Not sure if this is making any sense... Just understand that have to make this control go across several web pages that are already fully developed. I am just adding this in as new functionality...

I have a page that has a few requirements1. A Gridview that is dynamically populated (and refreshed at a regular interval) with a button control that is conditionally displayed 2. The button control should show a ModalPopup of a Panel that serves as a form 3. This Panel form contains a textbox populated with a value from the gridview and another dropdown control I can get 2 of these 3 requirements via a couple of different approaches (like 1+2 work, but 3 fails or 2 +3 work but 1 fails).The code pasted below is the closest I have gotten, and is actually my preferred method, and I was wondering if anyone could tell me why the ModalPopupTextBox1 is not rendered when ModalPopup button is clicked.If I place the Gridview1 outside of UpdatePanel1 (refresh controlled by Timer1), the ModalPopup Panel works as expectedMarkup: GridUpdate.aspx

The target control is a Button (ID = "btTest");
The following is in code-behind:
[Code]....
The click has been verified, but the popup does not show. Of course, if btTest is manually clicked, the popup will show without any problem.
Is there any way to show a popup window from code-behind?

I have a Repeater control that loads instances of a custom control I have built. This repeater looks like this:
<asp:Repeater ID="myRepeater" runat="server" OnLoad="myRepeater_Load">
<HeaderTemplate>
<table border="0" cellpadding="0" cellspacing="0">
</HeaderTemplate>
<ItemTemplate>
<tr><td><my:CustomControl ID="myControl" runat="server"
OnLoad="myControl_Load" />
</td></tr>
</ItemTemplate>
<FooterTemplate>
</table>
</FooterTemplate>
</asp:Repeater>
I bind to the Repeater through the myRepeater_Load event handler. My custom control is used to render an item within the Repeater. Because of this, I am trying to set properties on the custom control during the myControl_Load event handler. However, I do not know how to access the current item during the myControl_Load event.
Is there a way I can pass along the current item or access the current item during the myControl_Load event? If so, how?

I have a simple user control that I have placed inside a repeater. I want to access it through the ItemDataBound event of the repeater. Here's my code so far:
[Code]....
Not so sure what to do about all of this. I have developed a simple calendar using an XML doc and a repeater. The parent repeater contains a child repeater that lists events based on the date. I have a User Control that has some unique capablities for control the date in a link button. I want the user to click on the User Control and be able to use the information to do something. Bottom line, I want to access the linkbutton inside the repeater.

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.
