I have a Repeater on one of my pages like so: [code] But, when I run it it errors out with the message:'btn<% Container.DataItem %>' is not a valid identifier.I want to append btn to the Container.DataItem value so that I have dynamically assigned control names that are associated with the underlying data item. Any ideas?

View 2 RepliesWorking in VB.NET, in a repeater. I only want to display part of the repeater if one the data item's fields is set to true.I am struggling to write a line that will accomplish this but am trying along the lines of this:
<% If '<%# Container.DataItem.IsLive%>' Then %>
<asp:PlaceHolder ...
<% End If%>
I have a ListView in which i have a function that creates images for users.I pass userGender,userImage1name,userIsImage1Aprooved values to the function in which i generate image.ie. if user has approved image i return it back, otherwise i return default image based on gender.
My question is, is there any way to avoid passing 3 parameters to that function and to pass whole DataRow so i can get values of columns i need?In reality i pass about 12 parameters just made it easy for you.ie. i want to achieve something like that <%# GetImage(Container.Item) %> while in GetImage() i would be able to access Item("some_column_name") or C# version Item["some_column_name"].
I have a User Control which is dynamically placed by CodeBehind as follows:
Dim myControl As Control = CType(Page.LoadControl("~/Controls/mainMenu.ascx"), Control)
If InStr(Request.ServerVariables("url"), "/Login.aspx") <= 0 Then
mainMenu.Controls.Add(myControl)
End If
As per an example from my previous question on here.
Within this Control is a repeater which calls a database to generate values.
My Repeater mark-up is as follows
<asp:Repeater runat="server" ID="locationRepeater" OnItemDataBound="getQuestionCount">
<ItemTemplate>
[Code]....
The example above works fine, but I want to be able to prepend text to <%# Container.DataItem %> in the title attribute of that <p> to print to the browser like this is some text DATA_ITEM_OUTPUT
When I try to do that though, it prints this is some text <%# Container.DataItem %> exactly like that, ie, turning <%# Container.DataItem %> into text, NOT the value from the repeater code.
It was working fine before I made it into a dynamically inserted control, so I am thinking I might have something being generated in the wrong order, but given that it works without any prepended text
I'm trying to do this in an item_databound event of a datagrid in asp.net
Dim EntType As EmployeeEntity = DirectCast(e.Item.DataItem, EmployeeEntity )
but I encounter the error
Cannot convert to class EmployeeEntity
The EmployeeEntity class has the same members as the items in e.Item.DataItem's DataRowView items. so how else do i cast the contents, without having to actually set each property of EemployeeEnity individually, from the e.Item.DataItem ?
i m populating a datagridview with two columns i.e checkbox and papername.I m trying to show papercodes(not present in grid but in database ,in the same table where papernames are)in a single textbox with a comma seperator, when i checked papernames accordingly.

I want to evaluate the current DataItem being bound to a repeater and remove it from being added if my condition meets. I would have thought that setting e.Item.DataItem to Nothing would work, but it does not. Any ideas how to not add a DataItem to the repeater when a certain condition meets?

If e.Item.ItemType = ListItemType.Item Or e.Item.ItemType = ListItemType.AlternatingItem Then

In my application, I have been getting this error each time the treeView loads it's items. This error makes my application slow on load and takes at least two minutes to load.The error is: System.Windows.Data Error: 26 : ItemTemplate and ItemTemplateSelector are ignored for items already of the ItemsControl's container type; Type='TreeViewItem'
My xaml code for the treeview is: (I'm using VB.net on my ViewModel)
<TreeView ScrollViewer.VerticalScrollBarVisibility="Hidden"
ItemContainerStyle="{DynamicResource tviStyle}"
Background="#FFF0F0F0" BorderBrush="#FFE5E2DB"

The binding of the ItemsSource is an ObservableCollection(Of TreeViewItem) thats is filled from a database.
I have the following code. It works as is, but... I am not always going to have an even number of items in the RSS feed So, at the end of the table, I might have only one table cell on the last row. So, is there a way to count the number of ItemTemplates and AlternatingItemTemplate, so if it is an odd number I would be able to add another cell <td> </td></tr> and close the table row?

I have a gridview where each columns have two template fields. One is ItemTemplate and another is EditItemTemplate. Now in EditItemTemplate it will show some textboxes where i can perform necessary editing. I can easily fetch data from each cell by using the following code-
[code]...
But how can i fetch data when the grid view is not in editing mode that is in ItemTemplate. I have tried the following-
[code]...
But its getting the exception object reference is not set to an instance of object. This is probably happening because the above code should be used in a method like RowDataBound when a row is instantiated. But I have to fetch data from some other method.Again for clarification I want to fetch data when the gridview columns are in ItemTemplate Mode.
I use Visual Web Developer 2008 Express.I have Label1 in a DataList ItemTemplate. I wish to use a button to get the text from that label and add it to text in TextBox1 which is elsewhere on the page.
I know how to do this from a standard label on a ASP.NET web page but cannot work out how to get the text from a label inside a DataList ItemTemplate.
This is what I thought I should do Protected Sub submit_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles submit.Click
TextBox1.Text = TextBox1.Text & " " & DataList1.ItemTemplates.ItemTemplate.Label2.Text
End Sub
I thought that because DataList1.ItemTemplates.ItemTemplate.Label2 - System.Web.UI.WebControls.Label is what is written in the properties window header when I select the label in the DataList template.
When I try that, I get a Blue Squiggle under "DataList1.ItemTemplates" and if I hover over the squiggle the error box comes up saying " 'ItemTemplates' is not a member of 'System.Web.UI.WeControls.DataList'

I have a gridview as shown below. When the EmpType is contract the EmpID must be masked as "XXX"; for regular employees, actual EmpID should be shown. Also, when it is masked, I need to add a button control in the EmpID column.I need to do it using mark-up; not using code behind. How can we write the conditional logic for Gridview's ItemTemplate for this logic?Note: .Net 4.0
<asp:GridView ID="Gridview1" runat="server" AutoGenerateColumns="False">
<Columns>
<asp:BoundField HeaderText="AssociateID" DataField="AssociateID" />

I'm a newbie in asp.net. When using FormView, there is a big amount of code in ItemTemplate, EditItemTemplate and InsertItemTemplate which is almost identical.

ListView allows the use of LayoutTemplate - but I didn't see any examples that insert this kind of code in LayoutTemplate. And inserting this code in LayoutTemplate would result in an error.DetailView allows to produce code automatically but I'd like to use a specific design (for ex. using "fieldset" that encompasses some fields).
Okay, so I wrote a few custom ItemTemplates for VS2010 that implement IWizard in VB.NET (4.0). Straight forward enough. They work during my testing, but when someone else deploys and attempts to use any of them, Visual Studio throws an incredibly generic Exception has been thrown by a target of invocation error.
Stranger still, after they open up the project properties and try again... they work. Without changing anything. Anyone have any clue what is going on? Or perhaps even just a way of getting VS to give me a more specific error? I already tried devenv.exe /log but nothing out of the ordinary was there.
How can I create alternating background colors for listview rows while only using ItemTemplate? I don't want to use AlternateTemplate because I would have to edit both of them everytime I want to change something when all I'm using it for is to create the alternating background colors. So what's a way I could do it using only the ItemTemplate?
View 4 RepliesWith the ASP.NET Repeater control, I am used to being able to access my data item values in the ItemDataBound Event Handler by doing:e.item.dataitem("column_name")
However, it seems with the ListView control this is not possible. How can I access the data item values?
I have a parent repeater with nested repeaters.My problem is I am trying to use 'Next' and 'Previous' buttons to rebind my repeater (rptTabContent) and thus the inner repeaters also, but when I try to manipulate the state of these links during the ItemCommand event they are overwritten by the bind.

View 7 RepliesThis is more of a ASP.NET question, but we are using VB.NET so it might be relevant. We just recently upgraded an ASP.NET 1.1 project to 4.0.Once we started running through the app to regression test it, we found that (consistently) if we made a call like DataBinder.Eval(Container, "PropertyName") from a User Control, ASP.NET complained that it could not find the PropertyName on the page.
PropertyName *does* exist on the User Control, but not on the page.This worked up until we upgraded to 4.0.The fix we found was instead of using "Container", we used "Me" to reference the control that the code was being called on.
start a desktop app. make the form 1- MDI Container = True. 2- Right to Left = True , 3- change the Right to left Layout = True.Set the background to any jpg image, when you run the form, the backgroud disappears.
View 3 RepliesVB 6.0 had a Set Pixel function, which is not available in VB.net. using a draw ellipse function with parameters specifying a circle one pixel in diameter.The above is painfully slow.I have been drawing graphics in a Bit Map using a Set Pixel function & then copying the entire graphic from Bit Map to a Picture Box. This results in nothing seeming to happen for several seconds & then the entire graphic is displayed in the Picture Box.
The above does the job, but it would be nice to display the graphic as it is being generated pixel by pixel, which was possible using VB 6.0, Might there be a Windows 7 API which would set a pixel? Might Microsoft be considering a Set Pixel function for Picture Box graphics?
