I'm trying to add a title to the row header of a datagridview. I spent hours trying to get it to work to no avail. So finally I started a new project with only the very basic required code. It worked. I then copied the code from the basic project to my full project and the headers refused to show.

I am creating a DataGridView in code, not dropping the object on a form in the visual environment, and the row header is ugly. I have been playing around with this for a while. I would like the row header to look "normal", and it does not. The row header is slightly larger than the column headers, and the border is not showing. I also am not seeing the "*" or arrow(pencil) for current row selected.

I am reading a xml file and display all the data in datagrid view. But when I chose to display data of just one column only the data comes in the dgv but no column header. Same problem shows up, if I chose to display a particular row of a particular column. How can I fix this ??
Private Sub all_columns()
Try
ds.Tables.Clear()

At runtime, I am adding a DataGridView to a windows form. The final column is a DataGridViewImageColumn:
Dim InfoIconColumn As New DataGridViewImageColumn
MyDataGridView.Columns.Insert(MyDataGridView.Columns.Count, InfoIconColumn)
Adding the following code will get my Information Icon (bitmap) to display in each of the column cells but NOT the column header:
Dim InfoIcon As New Bitmap("C:MyPathInfoIcon.bmp")
InfoIconColumn.Image = InfoIcon
Also, it is worth noting that the image displays 'perfectly' in the cells i.e. it is sized correctly to fit the cell.
However, I cannot find a way to add the same image to the column header cell. After some googling I used the following code which placed the image in the header cell but left me with two problems:
The image did not 'auto-size' to the column headercell in the same way it did when added to the column cells. The image was slightly larger and blurred.
By using the _CellPainting event slowed down performance i.e. when hovering over the DataGridView to highlight the selected row the highlighting lagged behind where my mouse was placed.
Here is the code:

Does anybody know of a way to solve my problem and get a nicely sized, sharp image into a DataGridViewImageColumn headercell at runtime?

View 1 RepliesI am using the VB ReportViewer and report designer. I am not using the report wizard as I have had no success creating the report I want that way (I'm new to all this).
I have created a view holding all the columns I want to report on. Half the columns have values to be displayed in the body of the report in tabular form. The other half contain values on which I wish to group. Although there are several columns in this set, the values do not change except when the group value changes. Eg
Group col1
Group col2
Group col3
[Code]....
I cannot discover how to achieve this using the tools provided with the report designer.
I was wondering if there was a solution to replacing the tab control's tabs with custom tabs made in Photoshop. I know there are plenty of super expensive programs that can do it, but I was wondering if there was a way to do it programmatically. I was thinking that maybe it could linked in some way with a .DLL?
View 1 RepliesMy code is basically a file parser/editor and it handles most files fine as they hold a handful of records concerning family members. However there are a few files that crash when trying to deal with them. Here is the problem.Each family member record creates 3 tabs that hold an average of 3 group boxes each. Each group box holds an average of 3 text boxes.So each member record creates 3x3x3 = 27 text boxes and some files get up to 289 family members which = 7803 text boxes.
The problem is the rare file with 400+ member records = 10,800 text boxes which causes a crash due to using up all the window handles. Each member has a separate tab page (with 3 subpages) but really only a dozen or so member pages are visible in the GUI with scroll arrows to move through them so I was thinking of somehow making the GUI a scrollable window so the tabs get built, displayed and disposed as the user scrolls left and right through the member tabs.
The files are parsed into a 3d list DataList(x,y,z) where x is the page number, y is the group box number and z is the text box number. So all the data is available. The code then traverses MyList and builds GuiList(x,y) where x is the page number and y is the groupbox number with all the textbox.text linked to MyList(x,y,z) locations so all text changes are reflected in the MyList.
I already have a memberCount variable and I am thinking of building, say, the first 30 member tabs with the middle 10 being visible in the GUI. If the selected tab > 20, then dispose of the first 10 tabs and create tabs 30-40.I am thinking I will keep all the member tab pages so I don't have to deal with inserts and indexing problems but just dispose all the group boxes and text boxes for tab pages out of view. I already have a deep clone sub that clones members when the user wants to add a new family member and I am thinking I will have to add something similar when a tabpage is passed in for disposal, it traverses and disposes each text box, then disposes the group box for each group box on the tab page.Additionally, another routine will rebuild the group boxes from the data held in MyList(x,y,z) when a tabpage(x) is passed in.
Is there a way to access the field header name of a databound repeater within the header template. So insted of this....

I'm using the following code to populate a DataGridView with a worksheet. This is working fine, however, I'm unsure how I can get the Text from the page header. (not to be confused with the column header). Later in my code when I am exporting into an existing workbook with a new worksheet, I'm wanting to use the header text as the tab name. The header text being "September 2009" so that when I import/manipulate/export october, the new tab will be "October 2009" etc. [Code]

i m trying to load the tabs dynamically.(Using AjaxToolKit). Firstly, when i hit button1 on pageload, it loads tab1() (works good) and when i hit button2, itloads up tab2() All these tabs are ascx pages. In tab1 i m loading WebUserControl.ascx. it works okay.
Issues:
1) When you runthe code, first click on button2, it doesn't load tab2 dynamicaly but it does when u hit button1 for the first time.
2) Repetitive clicking on button1 or button2 should load the same tabs next to eachother again and again but it doesn't
3) Thirdly, the main issue is that I m tryin to load another .ascx on loadtab2() which should have webparts in it. I should be able to load an another custom usercontrol into these web parts dynamically. But i m not able to do so.
Here is my code:
Default.aspx
<p>
<asp:PlaceHolder ID="PlaceHolder1" runat="server"></asp:PlaceHolder>

View 5 Replieshow can i add TABS to my homemade webbrowseR?
View 1 RepliesWell, this time my target is to add and rename Tabs with tabcontrol, e.g.
I have a form and have added a TabControl to it and in the TabPages i have added RTB's,now i have also added a button which should add a new tab page to the TabControl, the thing is i know how to add a NEW tab but i also need to have a new RTB in each New created TabPage and after i create a new TabPage i wanna add the Title of that New TabPage. To add New Title to the New TabPage i have created a New Form in which i placed a TextBox so that that text that i type Into that TextBox should appear as the New TabPage Name.
Here's some code i tried, and i know that there's missing something and i know that the code may be written wrong but that's all i know, unfortunately?
Code:
Private Sub AddNewTabTool_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles AddNewTabTool.Click
Dim rtb As New RichTextBox

What I'm trying to do is emulate something that we have in C++ in Visual Basic. I have a large table of 25+ columns that I need to display in a grid (don't want a scroll bar). I'd like to use a DataGridView instead of a nightmare of textboxes and add "tabs" to a datagrid view. Lets say the initial tab shows columns 1 - 9, Tab 2 shows Columns 1 - 5 and 10 - 15, tab3 shows 1 - 5 and 15 - 18, etc....

Using VB.NET 08 I'm using the following code which loops through a datagridview and makes the buttons found in the list visible
HTML Code:CallByName(Me.Controls("btn_" & list.Rows(J).Cells(1).Value()), "Visible", CallType.Set, True)
This code works fine with no issue with the buttons on on the form. However when I placed the buttons in to a tabcontrol on the same form I get the following error:Object variable or With block variable not set.
Does this error relate to the way CallByName calls the button handler and that its different to they way you could otherwise produce the same result using
HTML Code:
button1.visible=true
