Web Forms :: How To Set Properites Of Child Controls
Nov 11, 2010
Is it possible to someshow select "child" controls of an <asp:Table> control so that I can view and set properties of the "child" control while in designer view? Its a real pain to have to edit properties of a child control in the source view. What I ultimately seem to end up doing is having to place or move any controls inside an asp:Table that I want to set properties on to the "outside" of the table and set all the properties on the control. After all the properties are on set on the control, using the designer,I can move it back inside the asp:Table. This is not the most troublesome of options but it would be nice if you could somehow set the properties of child controls using the designer.

I have GridView and a button inside its ItemTemplate
<asp:Button ID="btnSend" runat="server" OnClick="btnSend_Click" Text="Отправить"
ValidationGroup="mesGr" CommandName="Send" rowId=<%# Container.DisplayIndex %> replyTo='<%# Eval("Sender") %>' />
As you can see I want to pass Container.DisplayIndex to handler. The problem is that this is not just child od ItemTemplate - Button is a child of LoginView which is a child of a Panel inside ItemTemplate ) I found a way how to pass that Container.DisplayIndex: <%# (Container.Parent.Parent.Parent as GridViewRow).DataItemIndex%>

I need to programmatically fill DropDownList in FormView and can't find the proper event to do it. I keep getting "'GenreList' has a SelectedValue which is invalid because it does not exist in the list of items" or "Bind, Eval can only be used in databound control" depending on the event. Sample code follows (there's no attempts to bind a DropDownList there ):

I have a FormView with an EditTemplate.And the EditTemplate contains an ascx control:
<asp:FormView
ID="fvTicketUpdate"
runat="server"
[code]...
The contents of the ascx control has TextBox and DropDownList controls binding to the results of the FormView's ObjectDataSource through Text='<%# Eval("field1") %>'and SelectedValue='<%# Eval("field2") %>'.This works fine and I have been building all of my front end pieces like this as <asp:Panels> rendering as FieldSets that go 100% across the screen.And we call these areas "strips" accross the screen.But now I've run into a problem.One TextBox and one DropDown bind fine to a Ticket Object.But the DropDownList that works has its <asp:ListItems> hardcoded before hand.Now I have DropDownList that gets populated through a WebService in the ascx's
code behind like this:
public partial class UserControls_FormControls_PntipUpdtFaaInfo :
System.Web.UI.UserControl
{
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
[code]...
The Problem I think is the FormView is trying to do its Bind to the objectDataSource before its child ascx control is loaded in the Edit Template.And I am getting this error:
Databinding methods such as Eval(),XPath(),and Bind() can only be used in the context of a databound control.Meaning that the control must already be databound to bind the selectedValue to a Property of the TicketObject.Is there an easy way to force the order of loading to make the PntipUpdtFaaInfo control load and have its Page_Load execute and bind ddlEquip before the FormView does its first dataBind and executing its Evals?Otherwise I have to take out the eval on the ddlEquip SelectedValue attribute and go to the Parent Page and hack and force everything to happen when it needs to.This layout has worked out well for me.All of the ascx area strips across the screen share the same Validation Summary for example.It allows me to think about one section at a time and the Properties to the Business Obect and CRUD methods as I go.But this is a big brick wall I've hit.

am duplicating a site from a prexisting site. I am getting the error 'System.Web.UI.WebControls.Literal' does not allow child controls when my web application goes to process a function that implements keywords, description, title ect for a webpage. This is quite perplexing as it i not doing this in the website i duplicated from.
[Code]....
it looks at Header, i dont think it can find the definition in this second website so it is returning System.WEB.UI.EmptyControlCollection. In the first website it is returning System.Web.UI.ControlCollection. Also when I go to the definition for Header, it opens up the Metadata definition in the first website. In the Second, it says "Cannot navigate to definition".

I have a gridview with a template filed which contains an embedded gridview, which may or may not contain any records. I want to be able to make the master gridview row a different color for those rows whose child gridview has records. My plan is to add a sqldatasource to the page that targets the child gridview table and during the master gridview RowDataBound event I would check to see if there are any records and apply the formatting accordingly.

I am a newbie at .NET technology and I would need to make exactly same thing like at this tutorial : http://msdn.microsoft.com/en-us/magazine/cc164077.aspx#S1I don't need to edit button or delete button there, just expand and collapse rows of child table. I was wondering if there is not some more simpler way how to do this because the article is from 2003 and I don't understand it so much. And when I looked around this solution I found some SilverLight solutions but I can't use them.

We have a GridView2 in GridView1 EditTemplate.And we have a button (commandname="Update") on GridView2.When Button1 is clicked GridView1 goes into edit mode and displays GridView2.Now when Button2 is Clicked, we want the cell[0] value of GridView2 to be displayed as Label1 Text on GridView1 and comeout of the GridView1 edit mode.Basically we want to capture gridView2 cell[0] value and display that on Label1 of GridView1.We have written the below code. But we are unsure on how to grab GridView2.cell[0] value and display it as Label1 text.Can someone please assist us with this?Also, we are not sure if we can use rowupdated event for this. Please also guide us which events we should be using to achieve the functionality.

I have a webpage which does a lot of processing(for few minutes) and finally produces a result.
i have one more page which contains results of all previous operations.
Both pages are opened from a parent page. what i want is ,As soon as first page finishes its task , the result should be reflected in second webpage automatically.(Or we can say it should update the information according to the latest operation).So i need a page refresh at this instant. I don't want to do a regular interval refresh through Meta tag etc. Is it possible?
