I can set the value of a combobox on a form by using ComboBoxName.Text = "SomeText" but how can I do this if the combo box is within a datagridview? When I type DataGridViewComboBox the .text property is not listed. If I try to force it, I get an error.
View 3 RepliesI can't seem to set the selected index or selected value of a DataGridView combobox when loading data from a database. My DGV has two combobox columns which are bound to datatables. The DGV itself is not bound initially. After adding a row, I select a value from each combobox which then populates the rest of the cells in the row. I'm using the EditingControlShowing event to add an eventhandler to catch the SelectedIndexChange of the combo boxes. This all works as needed. My issue comes when populating the DGV with saved data, I need to add the rows and set the selected index and/or selected value of each combo box. I've searched through various forums and articles for the last week with no luck.
I'm using VS2008 sp1, .NET 3.5 sp1 and SQL 2005 sp2 Express.
I would like to manually insert values in a combobox colum of a datagridview.I am using the DGV as an UNBOUND control.
View 8 RepliesI have several forms that have a DataGridView object in them. I recently discovered the AllowUserToOrderColumns attribute. I set it to true and I can reorder the columns at will. The problem is that the order for these columns is lost once the form is closed. Ok, how do you save the order for these columns and then restore them to the form once it has been reopened?
View 4 RepliesI have a databound DataGridView, and I'd like to keep one column in front, with a slightly smaller width than the default. The grid's AutoSizeColumnsMode property is set to Fill so that the columns fill out the entire grid. This makes the first column equally large as all others, which is why I need to set its width manually. The smaller column is the first one with the checkboxes. I have two grids that I need to do this with, and for some reason it works just fine with the first grid, but gives a null reference error on the second grid...
Here's the code for the first grid (working fine):
vb.net
Public Sub UpdateTodoGrid()
' Load todo items
todoGrid.DataSource = _TodoManager.LoadAll()
' Set backcolor
For Each row As DataGridViewRow In todoGrid.Rows
[Code] .....
As you can see, the code is exactly the same (except for not setting the BackColor of each row and not using the ReadOnly property*). When I run this code, it gives me a null reference error ("Object reference not set to an instance of an object.") on the line where I set the column's Width. Obviously 'col' is not Nothing (otherwise it would have errored before that line), and there's nothing else there that could be Nothing... I assume that something happens internally in the grid when you set the width of a column, and that there is a null reference there, but obviously I have no control over that.
The grid's are absolutely the same, as the second grid is just a 'copy' (meaning I copy/pasted it in the designer) of the first. So all their properties are equal. I thought maybe the ReadOnly properties were the problem, but I tried putting them in in the same way and the issue did not go away... The first grid is not ReadOnly (because the checkboxes need to be editable), but all rows except the first are, while the second grid is completely ReadOnly.

View 1 RepliesI have a datagridview containing 1st column (combobox), 2nd and 3rd column is textbox. The combobox was filled-up using datatable.

I have a DataGridView control with two columns:
colName
colAnnounceURL
I also have a ComboBox that I need to bind to the colAnnounceURL in the DataGridView. So everytime I add new rows to the DataGridView, the ComboBox will be updated with the items in colAnnounceURL.
I have tried the following to no avail:
cboAnnounceURL.DataSource = dgvTrackers
cboAnnounceURL.DisplayMember = "colName"
cboAnnounceURL.ValueMember = "colAnnounceURL"
The code does not cause a crash but does nothing.
Both controls are visible to the user. The idea is to have DataGridView act as AnnounceURLs manager and ComboBox to set the active AnnounceURL.

View 1 RepliesI have an unbound DataGridView control that displays a few columns of account data. The first column is a combobox that I fill with data from a dataset of names filtered by what's in a customer field on the form. When you click on a combo on one of the populated rows, the available names come up in the combo. But if the first click in the datagridview is on a new row's combo, various (incorrect) names appear. Only after you click on one of the populated row's comboboxes, does the correct data appear in the new row's combobox control.
I don't really understand why this is happening. I have been using the EditingControlShowing event to populate and add the combo to the new row, but it doesn't seem to be working very well. I hope someone out there has some ideas about the correct way to do this.
