I just do not understand the combo box theory when you need to define the selectedvalue in a datagridview combo box. anyone have a working example? JMC had a lot of definition in other posts but.. i just did not grasp it. This combo box is in DataGridView1

I have a datagridview combobox column with data bind into it. I would like to set it selectedvalue to a value by default. How can I do it? because it does not have any selectedvalue option.

View 2 RepliesBelow is the code to create a single Editable ComboBox column in a DataGridView on a form. I believe I have follwed the instructions to allow the user to input new values other than those in the list, however if you create a new project and add a button and a DataGridView control onto the form, then copy and paste this code and run the program, you will find that you cannot type any character in the edit box other then characters that exist in the list and only 1 character will be displayed at a time. I have set the Autocomplete value to 'False' and setting it to 'True' at least allows me to type more than 1 character but still not any strings that don't exist in the list.You can even remark out or not use the entire Call Validating sub routine to see the issue of not being able to type in the cell.

View 1 RepliesI want to add a combo box to a column in a datagridview.It is displaying OK and the dropdowns are OK, but how do I get it to display the actual value in the box/cell?
With cmbLdecs
.HeaderText = "L Decs"
.Width = 60
.Items.Add("No")

is there a way to set a single cell as a combo box? it looks to me that you can only set the whole column.
View 5 RepliesWhen my form is loading, it executes a Method called populateListBox().As the ListBox is populated, it inevitably triggers ListBox.SelectedIndexChanged, which triggers this
Private Sub lstLabels_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles lstLabels.SelectedIndexChanged
Try
buttonCheck()
Dim pathText As String
[Code]...
If I stick the Try...Catch in, allowing it to bypass the error, everything loads fine and when I double click an item in the ListBox, I have a MessageBox setup to show the SelectedValue, and it works fine (it shows a number like it should). Even if I put a MessageBox in the SelectedIndexChanged event, I still get the same error on the MessageBox line during the loading of the form.
Is this because the form is not fully loaded that I get this error? And what would be the proper way to handle this? I need this code in the SelectedIndexChanged for when the user selects a new item, so how do I keep this error from happening (or maybe even the event from triggering) during form load? Because I'm sure having a Try...Catch is not really an accepted form of "fixing" an exception; it's just ignoring it.

I would like to define a class as something like a constant, and use the class directly rather than having to always create an instance. Is this possible? I've tried a handful of combinations of syntax, but nothing I've tried lets me do what I'm after. To give an idea of what I'm after:

View 7 RepliesI created a data grid view from the datasources list and converted 1 of the columns into a combo box. Unfortunately, the combo box isn't acting like a proper combo box. When I start typing, the combo box does not display the characters I have entered. All it does is begin looking for the entry that matches what I am typing.
This is no good for my purposes, the user needs to be able to see what they have typed. Is this how it works when in a grid? I have tried playing with a lot of the column options but nothing makes it work correctly.

I am building a simple GUI to view data within a database. I am getting stuck when it comes to filtering data. I have followed Beth Massi's video entitled How Do I: Filter data on the client?
However my datagridview will not filter, it simply moves the highlighted cell down to the location of the item selected in the combo box. The items in the combo box are also repeated as opposed to grouped by what they they are called, for instance I have a column called region and every cell contains the text "West" and the combo box just shows a list of all the cells as opposed to just one.I followed the video several times and every time this happens. Even with a new project. Could it be because my data isnt a table but a query of several tables? I can filter on this data in excel and access easily.
How can i load datagrid view combo using code? and how can i make it just like a ordinary combox, so that i can text inside of it?
