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....
View 13 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
[Code].....
I have buttons a few text boxes etc on a form, however I want to move it all to a tab (as in the tab control). I add a new tab control, cut all the buttons and textboxes, paste them into the tab control on tab 1. All good so far. When I run it, and click the buttons, they dont do anything. Do I need to move all the code to somewhere else or something?
View 5 RepliesUsing Visual Studio 2005 (vb.net) (windows forms) on Windows XP, I have a standard Microsoft TabControl.A button click adds/removes an image from 1 of the Tabs.Seems like the image is placed OVER my tab's text, making it unreadable.Why isn't it like it should be: Image on the left. Followed by text on the right.Why is the image being placed OVER my tab's text? Do I need to do some kind of "refresh" or "redraw" before it will appear as it should? I don't see any way to "make the image appear on the left edge of the tab". (NOT the tab-page.) ... and then place the text just to the right of the image. (Just like a normal image+text tab can do.)The code is pretty simple, it just gets an image from my ImageList: cfgTab.ImageKey = "PadLockClosed.png"' Show CLOSED PadLockThe tab's text changes from: This is my tab text to: T(IMAGE HERE)is my tab text The image appears OVER the beginning of my text. But if I move to another tab, then move back, the image appears in the correct position:(IMAGE HERE) This is my tab text
View 1 RepliesI have a TabControl on a UserControl. I want the UserControl to behave like a TabControl as usual (it contains only the TabControl and a Contextmenu), including Design-time behavior.I have spent the last two weeks finding out how to add the Design-time behavior and I think I have come a far way.The problem is with adding TabPages during Design-time (while the UserControl is a custom tabcontrol, it is using regular windows forms TabPages).In the Designer class, I have the following code to add a TabPage:
vb.net
Dim dh As IDesignerHost = DirectCast(GetService(GetType(IDesignerHost)), IDesignerHost) If dh IsNot Nothing Then Dim i As Integer = tc.SelectedIndex Dim name As String = GetNewTabName() Dim tab As TabPage = TryCast(dh.CreateComponent(GetType(TabPage), name), TabPage) tab.Text = name tc.Controls.Add(tab)
[code]....
So it would add the control to the TabPages collection if it was a TabPage, and use the regular routine otherwise.
(I'm now using 'tc.Controls.Add(tab)' again instead of 'tc.tabCtrl.TabPages.Add')
But, I don't think the designer even gets that far because it is telling me I cannot add TabPages to my usercontrol, because only TabControls can accept TabPages... How can I make my usercontrol understand that it is a TabControl (without Inheriting from a TabControl?)
VB2005 - I have a tab control on my form and have a DataGridView in each which I populate from two different databases. All that works great. Now after I populate each grid I also want to autoresize the columns so I have dgv.AutoResizeColumns(DataGridViewAutoSizeColumnsMode.AllCells).
However if the specific tab of the grid is not set selected there is no autoresize. I have confirmed this with the exact same code run once while the second tab is not selected and then again when the second tab is selected. In the first case the columns do not get autoresized, in the second case they do get autoresized. Is it mandatory that I select that tab to allow the columns to be autoresized?
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.
I am trying to display an usercontrol(has several panels one on top of the other panel) on tabpage. I am using below code to achieve this.

i have a datagridview with three columns. i set the first column to visible=false, so the user can only see two columns.when the user presses the tab key in the first visible column -- column(1), i want to ignore column(2) so that the user only tabs through the rows in column(1)i can't get it to work. it will always tabs through the rows in column(2) even if i use the column name.

I have a datagridview and two datatables. I am comparing the information in the two datatables. Now, if the data exists is datatable2 but does not exist in datatable 1 I would like to add a row to the bottom of the datagridview and fill in the necessary information.
Can someone give me an idea of the necessary syntax that I will need to accomplish this goal? Also, I know this post is a little vague and if more information is needed to answer the problem I can give it.

I would like to add a row into a DataGridView: The first column is a string All of the middle columns are of integer type (for sorting) The last column is a string All the values above are passed to the Sub by a array (currentRow) of type String. However, the middle values have to a go through a type change to type Integer for sorting The following Sub works perfect except: The number of items in currentRow (the columns) may vary Then the hardcoded dgProduction.Rows.Add() code at the bottom with not work properly because it is fixed with a total of 6 columns. note that the length of currentRow() will not vary during the population of a single population event. Instead it may vary once I have cleared the grid and click on a different date. So all the rows within the grid will have the same number of columns.

I have a DataGridView that is bound to a DataTable. In this DataTable is a column that contains an image path location, ie; c:imagesmoon.jpg. In the DGV, I'm only displaying 2 columns, the "Name" of the image and the "Image" itself, which basically is the path information. how do I get the image to display in DGV Column? Because even though it's bound...no data comes up when I run the app.

I'm having an incredibly frustrating problem with datagridview that seems like it should have a very simple solution, but I haven't been able to find it yet.I have a form with a datagridview on it that is only usually 1 to 2 rows long but can be much longer. So when the form loads it populates the datagridview with values for however many rows there should be, and there is a blank last row. On the column header on that last row is an asterisk. If you click on the asterisk or anywhere in the blank line, it adds a new row where you can enter data, however, the blank line with the asterisk does not move down to be under it. In fact the asterisk stays on that line, and if you click anywhere on that same line, it adds another row, placing it on top of the one that was just added, and this can happen forever. I have a sub that refreshes the whole table and repopulates, however I can't run it in the new line code with an "Operation is not valid because it results in a reentrant call to the SetCurrentCellAddressCore function." which I can't seem to get past. If I exit the form however and come back in (it runs the refresh on loading), now all the lines that were added show up, with a blank line with an asterisk at the bottom.
View 1 RepliesI have an Access database with a Parts table. I'm using tableadapters in my project. A datagridview on my form is filled manually in code. One column of the DGV contains a columntype of combobox. I've got a bindingsource on my form whose source is the Parts tableadapter. The combobox column is tied to the bindingsource and is displaying fldDescription.
The part descriptions can be changed by the users, but the original part description is saved in another table that is used to fill the grid. If part "widget" gets changed to "widget, large" I can no longer display "widget" in the combobox of the grid. I need to know how to be able to add it to the bindingsource so I can display it in the combobox. I don't want it saved to the Parts table though.
I have a Datagridview with a bound datatable in it. Then I add a check box column to it.
When I click the headder of the DGV, it sorts the bound columns, and clears all checked checkboxes in the checkbox column.
How do I bind the checkboxcolumn to the rest of the table?
