Unbound Populating Data Grid
Jan 27, 2009
tried quite a bit of iterations, not a local admin so i dont want to even bother using the data connection wizard, want to do all of this with unbound controls only the harder way for learning purposes and also so i dont have to keep logging in as local admin and create data sources in the future. Cant really seem to get the table to fill, it appears always with blank fields, and tried many different ways. Currently using vb. net 2005 msvs.[code]

I have seen multiple examples on google and on these forums about how to do this. It seems there are two approaches:
1 - Add the column directly to the DGV and populate it
2 - Add the column to the underlying dataset

I am wondering if data grid automatically shows a first column (empty) before the others, if that can be edited out.

I have an unbound DataGridView that I am trying to fill with data, but am having a problem with the combobox column. I create the columns like this:[code]That works, and I have my columns like I want them, but I don't know how to add a row AND select the appropriate item in the combobox. I am adding items like this:[code]I can't figure out how to set the combobox column. And to top it off, since I changed the column from a text column to a combobox column, the grid is throwing exceptions, although it doesn't tell me what's wrong, it just tells me to handle the dataerror event, and all that I can get from that is e.Context = 3 and I can't find out what that means. Probably a type mis-match, but I can't find the proper way do select from the combobox. The rows add OK, but when I scroll the combobox column into view the first item is selected then the errors get thrown.

i am using an unbound datagridview so i can dynamiclly add rows. all that is working fine. but the grid is not is the location i have coded.. i am using the defualt form as a base then coding the unbound stuff in.. should i just create a blank class file and do everything? the only problem i am having is the grid must bees in the correct location according to the pixel point that i have given it. Right now it is placing the grid at point (0,0) no matter what point is entered on the line for location. so what am i missing??????

This is a VB .NET application where we are showing the output of a SQL statement in a Datagrid view. using .NET 2005.We need to get the seperators of the headers on the grid control to be the same colors as the GridColor on the form. See the picture below:We've tried looking through all of the properties of the DataGridView control, and found some interesting things that looked promising such as the DataGridViewAdvancedHeaderStyle, and DataGridViewHeaderBorderStyle, but none of it seems to allow you to change the colors on it.Does anyone know how to do this without remaking the entire thing with a GDI+ control?

I have the below code that i am trying to have two datagrids with a grid splityter in the middle. The split seems to be working fine but the issue i am having is when I populate the datagrid it is growing in height and changing the splitter instead of leaving the height alone and adding scroll bars.
What simple thing am I overlooking?
<Grid x:Name="gdHistory" Grid.Column="0" Grid.Row="2" >
<Grid.RowDefinitions>

I have a simple windows form that i would like to send the values of a few textboxes and comboboxes to an rdlc report after saving them (I have VS 2005 standard, so no crystal reports) - it's as follows:
-1 form
-3 textboxes - textbox1, textbox2, textbox3
-1 label - label1
-1 combobox - combobox1
-5 buttons - button1, button2, button3, button4, button 5
the textboxes are labeled length, width, height the combobox is labled unit of measure and contains two options - inches or centimetres the label has text of "your total cubic inches/centimetres is:" - followed by the unit of measure selected.the buttons are labeled save, calculate, print, print preview, and exit.Having said all of the above, the save, calculate and exit button code is easy enough and is good to go - it's print and print preview i'm stuck on the solution i'm after is to take those values and send them to an rdlc report that immediately prints (calls up the default printer dialogue) without preview or anything when the print button is clicked and also have a print preview function as well for when of course the print preview button is clicked.The report has already been created with the titles mentioned above..

I have a form and in that form is a datagridview listing information from a table in a database. The datagrid is setup as read only and the user is unable to move the columns around. The purpose of the datagrid is to allow the user to select entire records and press a menu button that does some action on them. To make it easier to use the very first column in an unbound data column that I fill with a number representing the row count so 1,2,3,4.... this makes it easier for the user to count how many rows he has selected.
The problem is that the unbound column moves to the last column in the datagrid at random times.This only happens in development not after the application has been deployed. Its annoying because lets say I go in to add a label or change a menu item on the form that has nothing to do with the datagrid I have to make sure that the unbound column hasn't moved.Has anyone else had this problem mixing bound and unbound columns in a datagridview.
