View 2 RepliesI've got the following issue: I want to make my program change the Backcolor property of all textboxes inside a TabControl. The problem is that one of the Tabs has got another TabControl in it, and I need to change those too.I'd like to to it all at once, but I'm getting an error using this code.
vb.net
For Each SpeechTextBox As TextBox In TabControl.Controls
SpeechTextBox.BackColor = ColorFondoTablasUSE[code].....
The error I get says this:
System.InvalidCastException was unhandled
Message="Unable to cast object of type 'System.Windows.Forms.TabPage' to type 'System.Windows.Forms.TextBox'."
I read somewhere in the forum how to make this work, but I can't find it.

I have 2 button in ASP.net, when i pressed button1 my div innerhtml changed to some value. and when I press the button2 my datagrid will display in the same div.
how can i display the datagrid inside the div at runtime.
I have spent all day searching for this but dont know what to do, I want the datagrid to be visible to the user allowing him to scroll it as well but i dont want the Grid to be selected, I want the selection to be done by the program
So how do I enable scrolling on a Datagrid that is disabled??
I am working on arrays and I am currently having trouble with searching and finding arrays. In this example, the user should be able to enter a Name, and it will output that person's stats.
Here is the text file (note, I should be able to go to this text file, add a few more names and the code should still work, which is why I am using loops,arrays,text files instead of if and else statements),
Kobe,29,6,4
Allen Iverson,28,7,4
Jason Kidd,12,10,9
So if the user enters Jason Kidd in the text box, this will display in another text box:
Jason Kidd averaged 12 points, 10 assist, and 9 rebounds.
[Code]...
All right now is the searching part. I really do know how to search for what the user entered and display the statement in a text box. I kind of have an idea of how to just get the name, but for it to get the name and then all the data for that name puzzles me even more.-I tried using .contain, indexof and few others.
I know to display the information in the text box will be something like:
textboxoutput.text = PlayerName & " averaged " & PlayerPoints & " points, " & PlayerAssist &" assist, and " PlayerRebounds " &" rebounds"
So basically, I want it to where the user can enter a basketball players name and display the values for that name.

I've tried a few different methods I could find in order to connect my VB .NET program to a book store's database. While I've been able to connect to it and display the contents of its tables in a DataGrid, I need to be able to search the tables and display specific records, depending on the contents of appropriate the adjacent text boxes.[code]This is a code I've used for a very similar process, just really aims to search a different field in the table. If this is easier to adapt into a code that allows searching and producing specific records in a database, please use this one.

View 1 RepliesI'm working in VB.Net w/ WPF and I need to create a DataGrid at run-time (in the code-behind) with the text in each grid cell able to wrap. I've found a lot of examples showing how to do this in the XML but I can't find anything explaining how this is done in the code-behind. I'm stuck trying to figure out how the DataGridTemplateColumn, CellTemplate, and DataTemplate all work together.
<DataGridTemplateColumn>
<DataGridTemplateColumn.CellTemplate>
<DataTemplate>
[code]....
I think the problem is with the binding and the textblock property. Something like this would make more sense but it doesn't work...
Dim b1 As New Binding("Wrap")
factory1.SetValue(TextBlock.TextWrapping, b1)
I have a datagridview (windows forms) that is inside an mdiChild form. The custom format is given by a "for" instance, something like this:
For row As Integer = 0 To .Rows.Count - 1
If .Rows(row).Cells("someNumber").Value = 0 Then
.Rows(row).DefaultCellStyle.BackColor = Color.DarkSeaGreen
End If
Next
So, for every row in the grid that you find, if ther value in the "somenumber" =0 paint the whole row green. Problem is, if I put the form OUTSIDE of the MDIParent - just put frmMyform.show() in my btn that calls the form-, the grid WILL apply the format; If I call it like frmMyform.mdiparent = frmMdi, then frmMyform.show, the grid WILL NOT apply the format.
