View 1 RepliesI have this test form where I'm testing the idea, but ran into a snag. Now the main idea is to load all the data from a dataset into the one column of the datagridview. This works perfectly as shown in the image. Now there is something that I want to happen, but just can't get it right. when on the DataGridViewComboBox Column I also want to be able to type in my own data if the one I want is not available in the combobox.
Also if there are 50 values in my combobox and 2 of them are:
jacky, jacson
When I type jac, I want the combobox to only give me the options starting with "jac"
Here is the code that I'm currently using:
Dim dt As DataTable
Dim dsNewDataset As New DataSet()
Dim i = 0, intSetArray As Integer = 0
Public Function JT_PullDataWithCOLUMNS1(ByVal Cols As String, ByVal TableName As String) As DataTable
[Code] .....
I've hit a small issue on a project of mine. I have a comboboxcolumn on a datagridview and the items list has the items ("enabled" "disabled") as the values (stored at design time). When my sql table gets the value "Enabled" or "ENABLED" stored somehow as it's value then I throw a dataerror.
I am trying to avoid this dataerror, I was told to modify the value during the cellformatting event however with my experience the dataerror fires before the formatting. What is the workaround to this behavior? As a textboxcell type the error is not present, it's all because of the case sensitivity of the "items" list on my comboboxcell
I have a combobox in my form which I want to fill with data from one column in an SQL database. Any idea on how I do this?
View 1 RepliesI have a data-bound combobox that pulls values from a BindingList(of T). Combobox loads fine, correct values are displayed (I'm not using SelectedItem or SelectedValue). I'm using properties and connecting the data to the control via a bindingsource.
What I want is if the user types text into the combobox, I want the data from the bound table to change to that new text, i.e. edit the bound data directly.
Easy as pie to do with a textbox, but can't seem to get a combobox to work this way.
I was trying to use the validated event of the combobox to write the data to the datasource, but it doesn't fire when I press enter. Is that the way to do it? Can I not link the data to the combobox directly?
I need this code urgently try to sort out my problem and please explain the code with proper way.

I'm trying to bind data to a combo box but it does not appear to be working. I've setup the DataSet and the DataSetBindingSource and all this appears to be working, within the form design I can expand the little arrow in the ComboBox control and preview the data. This appears to be working but when the application is run, nothing appears in the drop down box.
