I have placed a button on data repeater (called datarepeater1) so that it is repeated with other controls. When I click this button, How do I access/reference the text value of a textbox control called TxtAnimalID on the same row? (This would be something like the current row I am on).

In order to dynamically add the hyperlinks and images I have placed them within a panel in the data repeater and am adding them in the ItemDataBound event.The problem is that only the first image is being written to the datarepeater.[code]
View 2 RepliesI have to make some automatization on a web server, I use Visual Studio 2005 Visual Basic Windows Console Application. I want to make a load/performance test of the web server, so I open several Internet Explorer instances, and I login the application, that is not a problem. But after that I have a mess on the page and I cannot make any more automatization...The composition of the page after the login is like this: I have the default form, another form and a multiple data window(mdw) controller, which dinamically can switches the forms on this part.
The problem is that I don't know how to access the controls of this mdw forms. I couldn't find much about this mdw controller and I am not an expert.
My code is here:

I am using a repeater to build a custom table. However, I can't figure out how to make the table show subtotal if the next rows tour does not match the previous rows.
Something similar to that.
row1 tour1
row2 tour 1
tour1 subtotal
[Code].....
but this shows all the data in the nested repeater not the ones that match the parentrepeater fields for example tour,theme,dep7 should match in the child repeater

If I have the following ListView, how can I attach a SelectedIndexChanged event listener to the DropDownList so I can perform a command on the respective object? Imagine I have a list of new users and I want to add them to a usergroup by selecting the group from the DropDownList.

I'm using a repeater ListOfArticles and have controls inside it like ddlSizes and btnSelectArticle. Normally you can just double click the control and in the aspx.vb page you can specify an action. I have heard something about Findcontrol, but can't figure out or find much information that I understand. I don't want to sound like an ass, but I would really prefer help for the aspx.vb page and not in C# or Javascript.
An example of what I'm trying to do is, once you've clicked btnSelectArticle the label lblSelection receives the following values Amount: txtAmount - Size: ddlSizes.SelectedValue.
<asp:Repeater ID="rptListOfArticles" runat="server" DataSourceID="objdsArticleList">
<asp:DropDownList ID="ddlSizes" runat="server" AutoPostBack="True"

View 1 RepliesI have an ASP.NET Web Site I am creating in Visual Web Developer 2008 Express using Visual Basic as the language. It is actually a rewrite-with-mods of an existing ASP script and I'm trying to chew what I've bitten off. I created my page with a text box (txtOutput) on it and since the end product is very complex, and it's generally good practice to separate like functions, I have created 4 separate classes in the App_Code section. My main page is Sync.aspx and has a code file Sync.aspx.vb with it. One of my code files is SyncDatabases.vb and in it I have created
Public Class SyncDB
In that class I have created some routines such as
Public Function ReadMSDB(ByVal SQLString as string) as Boolean
In this routine I want to put information in my text box txtOutput on the main form (the default - Form1).
My problem is that if I try:
Form1.txtOutput.Text = "Hello world"
or just
txtOutput.Text = "Hello world"
it says Name 'Form1' (or 'txtOutput') is not declared. I am sure I am missing something simple but have no clue what it is. I assume it's the fact that the write command is in a file (class?) outside the file (class?) containing the page itself but I don't know how to address it properly.
I am trying to create an app that adds tabpages into a tabcontrol which has a several controls on each tabpages. However how do I access those controls?lets say the controls I add are named label1 and label2. the tabpage is named infoTab1.

I have an application that has a grid of rich text boxes on a panel. I would like to access and modify the text in the various rich text boxes during run time. I know this has been brought up a bazillon times over the years, but I would have done this as a series of control arrays in VB 6. Below is a simplified representation of how the textboxes would appear in a panel if control arrays were availble:
rtbA(1) rtbB(1) rtbC(1)
rtbA(2) rtbB(2) rtbC(2)
rtbA(3) rtbB(3) rtbC(3)
I find that I can access the properties of the rich text boxes via panel1.controls.item(x).text, for example, where x is the control index assigned by the panel when I dropped the controls on it.
Since I created the rich text boxes at design time and dropped them on the panel, it has arbitrarily assigned the index values, and they are not in the index order that I would desire.
How does one re-assign a control's index at design time for a controls collection on a panel? And if one has 24 text boxes on one panel, is there a way to break them into subgroups, such as rtbA(), rtbB(), rtbC() with their own index values?
I'm trying to iterate through a group of ComboBoxes and set a property using a concatenated string & variable to represent the name of the control. However, I can't get the instance of the form to recognize the (String & Integer_Variable) as one of its controls -- and so it doesn't recognize any of the appropriate properties or subroutines as members of the System.Windows.Forms.Control.Is there a cleaner way to do this?
For myTempCount = 1 To 6
If tempValue < Me.("ComboBox" & myTempCount).Items.Count Then
ComboBox.SelectedIndex = tempValue 'appears to work -- how?[code].....

Upon form loading I create the form handle into a dictionary. then I call that dictionary ID and add data to the controls. I can't seem to add data to the controls inside the panel.. I think it is something simple. I may just be over looking the method I need to call.
View 11 RepliesWhen I try to access the controls of a form which is not yet created (i.e. to modify the contents of a text box , to press a button etc) , I fail , usually without even an error message . I found out that the only way to make my program go right is to take care that the form is first created before I try to access anything on that form . However this means I must use the Show method to create it and then to Hide it , which leads to an instant awful optical effect . I remember back in VB6 there wasn't such a problem ; it seems that in VB6 each time I accessed a control on a not-created form led to the form being created silently . Is there any way I could do that in .NET too in order to access my precious controls ?
