Feb 19, 2009

I have a datagridviewcomboboxcolumn which has its .DataPropertyName set to a int field, its .DisplayMember set to a nvarchar field and its .ValueMember set to a int field on a lookup table. I have captured a dataerror which states that the control is trying to push the .DisplayMember(nvarchar) to the .DataPropertyName(int) field. When I load existing data it works fine. When I try to leave the datagridviewcomboboxcolumn after selecting a different value in it or leave it when I add a new row, I get the error. What am I doing wrong?

Compare The Value Of DataGridViewComboboxColumn In DatagridView?

Aug 15, 2011

My application is in VS2008 coded in Vb.net I have a datagridView on one of my form.This is filled from the database at the load event of the form.The datagridView also has a column of type DatagridViewComboboxcolumn. This DatagridViewComboboxcolumn already has 4 values added to it in its collection during design time.My requirement is when the data is loaded in the datagridview, the corresponding record which is supposed to be loaded in DatagridViewComboboxcolumn should compare its value with the value of DatagridViewComboboxcolumn.And if the value matches than that value should get selected in DatagridViewComboboxcolumn. The database will have the any of the 4 values that are already in DatagridViewComboboxcolumn.It just has to compare both values and select the matching value. Below is my Code

query= "Select Record1,Record2,Record3 from TableName"
cmd = New SqlCommand(query, connection)
dr = cmd.ExecuteReader()

DataGridViewComboBoxColumn Cell Value Is Not Valid

Jul 11, 2010

I get the DataGridViewComboBoxColumn cell value is not valid only when the record in the ComboBox table does not exist. I have done quite a bit of searching on this and I can't find this particular situation mentioned.

I have a datagridview with a comboboxcolumn on it, both generated entirely in oledbdataadapter code. The datagridview is created, then the combobox is created, then the combobox is added to the datagridview, then the datasource of the datagridview is set. It works just fine. Except if there is no matching record in the combobox table I get the "DataGridViewComboBoxColumn cell value is not valid" error popup. I could trap the error but it seems to me a beter way would be to prevent it from happening. Is there some property I can set or something I could do to compensate for the situation where there is no match in the combobox?

DataGridViewComboBoxColumn Change Event For Dgv?

Oct 13, 2011

I have a dgv with several DataGridViewComboBoxColumns and when the user selects an item from one of these (product dropdown), i need it to repopulate another combobox (color dropdown) in the dgv for that same row - based on the value i get from the product dropdown. I've tried using the EditingControlShowing event; however, it only fires when I first select the dropdown .....?

Is this the right event I should be using? My other issue is that I don't know how to have the color dropdown re-populate for just the column and row I've selected. Here's my code so far for this event:

Private Sub DataGridView1_EditingControlShowing(ByVal sender As Object, ByVal e As DataGridViewEditingControlShowingEventArgs) Handles DataGridView1.EditingControlShowing
Dim myRowIndex As Integer = 0

I have a bit of a dilemma - in the ComboBoxColumn, I have added various numbers from 0 to 11. I need people to be able to type into the ComboBoxes in that column if the Combobox doesn't contain a value they need.I realise that I have to change the ComboBoxStyle to DropDown but am not sure how to. Also, for each row in the ComboBox, I believe I have to add the item that the user typed to the ComboBox list items for it to save but am also unsure how to do it.
