.net - Integrating Repeater Control Into Current Page?
Feb 7, 2011
So I currently have a aspx page that shows details for any single staff member, and the page is setup with mostly ASP labels. I have a subroutine called "getstaffdata" that populates the page on load (via subroutine).
I would like to convert this to a page that shows details on one staff member, or many staff members, one after another. So I thought of using the repeater control, but I'm not sure how to convert the page over. The staff userids are passed via query string, but I'm just confused on how to do the datasource for the repeater control.

I have an aspx page containing a number of asp:Repeater Controls.Im not using the default code-behind file that is generated, ive changed this to file in a different folder.In the code-behind, i populate the repeater controls, all was workign fine until i added another repeater control to the aspx page.In the code-behind, the intellisense picks up this control and i can access its methods and properties to set the datasource and bind the data. However, when i go to build the project, i get an error "The name Repeater1 does not exist in the current context"Firstly, all the other repeater controls, declared in exactly the same way, do not throw throw this error.Secondly, yes the repeater does have a runat="server" tag.Thirdly, It is not inside any other controls.I have tried various different methods of accessing this repater instead of just "Repeater1." but each returns null:
Repeater r1 = (Repeater)Page.FindControl("Repeater1") ;
Repeater r1 = (Repeater)Page.Master.FindControl("Repeater1");
Repeater r1 = (Repeater)Master.FindControl("Repeater1") ;
Ive no idea why this "doesnt exist in the current context" as all the other controls on this page do, even if i create a literal i get the same problem.

I am experiencing an issue with the TreeView control when loading new pages. It is databound to web.sitemap, but when loading a new page, it does not select the node of the current page, just resets it to the root. THe new page loads fine, just not preserving the current navigation in the tree view.

How can I integrate my aspx page into my existing php/html frameset page? So far I've designed the aspx page, now I need to know what to put in my button_click event.
In javascript I use this to get one textbox's text:
var t1=window.parent.text1.getText();
and this to set another textbox's text:
window.parent.text2.setText("text");
How can I tie this in to my button_click event?

So what I have is a bunch of dynamically created textboxs that when the user enters some data and either tabs out or clicks out some calculations are done. After the page posts back control focus is lost. What I need is to be able to set focus back to the control that was tabbed to or clicked into not the control that data was entered into.

On my asp.net page, I have several DropDownLists. I also have a Repeater.
In the ItemDataBound event I want to get the value of these DropDownLists, to change the data in the Repeater. The SelectedValue of these DropDownLists is empty. But after the ItemDataBound, the Page_Load is executed. There I can get the value of these DropDownLists.
Is there a solution to get the value when the ItemDataBound is executed.

Suppose I have an asp:Repeater that I am using to display a list of names and phone numbers.
<asp:Repeater runat="server">
<ItemTemplate>
<p><%# Eval("name") %></p>
<p><%# Eval("phoneNumber") %></p>
</ItemTemplate>
</asp:Repeater>
Now, let's make it more fun. Let's suppose that there is one or more phone number per name. I feel like I could use a repeater within a repeater to repeat the phone numbers. I could also use a for loop in my asp code. However, the Eval function is the only way I know of to access the current record at runtime and Eval only returns a string and only runs in <%# Eval("X") %>. How can I get the list of phone numbers that is a member of the current record?

My web application has user control which uses third party controls called Devexpress controls. The user control is a menu and is part of the Master page. It is placed there because this needs to be available in all the pages. My user controls raises a even on item clicked. Now, My question is that Is there any way to know that the event has occurred in page_load of the current page in which I am in?

I am looking for a way to figure out the current URL that the page is currently on (NOT what the asp.net page currently is, but where the CODE is at). ie. My web app is located at: [URL] my code is: String page = [URL]
String response = GetResponse(page); //basically the above code goes to the website [URL] and parses the HTML within it and brings it back and populates the variable string "response". But, sometimes the [URL] throws me a curve ball and redirects me to: [URL] I want to be able to use a try/catch to be able to "catch" the error of a different page: ie validateUser.aspx. So, I need to do to this: try
{
String page = [URL];
String response = GetResponse(page);
}
catch
{
//code to check the behind URL to see if [URL] is the URL OR IF [URL] is the current URL
}
understand I know how to find the URL of the current page the web app is on. I need to find the current page that threw the exception during the execution of the code behind.

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.

I am building in error-logging into my site, and want to be able to get hold of the current page name that the error occurred in, as well as the specific subroutine or function, to then pass to a VB.NET function. Is there anyway to get hold of this information without hard-coding the names manually? For example,
Dim strCurrentPageName = ???
Dim strCurrentRoutine = ???

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?

This is throwing object reference null exception

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 have a page with a gridview control that shows files that have been uploaded to our site. The name of the uploaded files, who uploaded them, and if they have been downloaded, etc are stored in a table. The gridview is bound to the table through a sqlDataSource control. I have a button column in the gridview that downloads the file associated with a row when the button is clicked. All that works well. I have a check box column that shows checked if a file has been downloaded. When the download button is pressed.
the file downloads and then a short routine is run to update the downloaded field in the uploaded files table to set the downloaded field to true. This is done through a command string. All this works. Here is the question. After the update is run I do a databind on the gridview to update it. The databind is run in the PageLoad event is the page is a postback. This does not cause the current row to show downloaded =true (checked). If I refresh the page in the browser then it displays correctly.

Per different user mode, some pages should not be accessible by users unless they have a valid session key.In your opinions -- would it be better to have a list of acceptable pages in the master page, and check if the current page is valid for the current user? Or handle this on every child page?I'm thinking master page, just want to hear what your input would be.
