Working 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 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 RepliesI 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?
Protected Sub rpt_OnItemDataBound(ByVal sender As Object, ByVal e As RepeaterItemEventArgs)
If e.Item.ItemType = ListItemType.Item Or e.Item.ItemType = ListItemType.AlternatingItem Then
If true Then[code].....
With 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?
There is any container for vb.net like the map in c++?

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?

View 1 RepliesIn my program, I want the user to be able to move an MDI child window anywhere inside the MDI container but I need it to be kept completely inside the container boundary. For example, the upper left corner should never be at a location less than 0,0 when moved left or up. Currently, if I slide the child window too far left, it extends outside of the MDI container window and the MDI container shows the bottom scroll bar.
Is there a way to prevent the child window from moving outside of the boundaries of the container window? I tried adding code to the .move (see below) so that if the new location was less than 0,0 then it reset it to 0,0 but then the child window controls flicker as the window is moved beyond 0,0 and the logic moves it back to 0,0. It appears that even though the code changes the location to 0,0 and the window shows the child moved to 0,0, when the mouse moves again, the window jump back to its unmoved location.
Private Sub MyForm_Move(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Move

View 13 RepliesI need a recommendation for a data container. I am loading a sequence of letters (Latin characters) into a text string.I then want to pass the individual characters into a 2-D matrix-like container (i.e. populate left to right based on # column assumption).I then want to search for patterns within this matrix using rules similar to that of a crossword puzzle (Left to Right, Top to Down, Left to Right Diagonal).What is the best container to do the anlysis in?I am assuming the decision to this will be based on the search flexibility of the container.My initial goal is to use crossword puzzle rules as noted above.But I may want to expand this to search backward as well (ie. Right to Left).
