Given a datagridview, using complex binding I have a datagridviewcomboboxcolumn that displays data from a different table. My question is: when the dropdown list of the comboboxcell is shown is it possible to display a different text than the DisplayMember, lets say more detailed?I search for a solution but could not find any.
View 3 RepliesI have a DataGridViewComboBoxColumn, and want to switch the style of the ComboBox control between DropDownList and DropDown (mainly for the text field editing capability). I'd like to do this on a row-by-row basis (at the DataGridViewComboBoxCell level).How would I do that programatically? Or maybe a different way of asking: How do I access the ComboBox control given an object of type DataGridViewComboBoxCell?
View 1 RepliesI searched "All Window Form" but I didn't find a thing which you use to select an item from a list by clicking on the selected item (like the thing you have to press on while selecting what Prefix you use when starting a thread). I guess it's easy to find, but I checked the whole list twice.
View 10 RepliesHow to query a record in vb.net using combo or textbox via linq to sql like the search engine? Just like when you search in google or youtube, once you typed in the initial string on the textbox or combo box it will show a drop-down list. I tried to use it in my application using linq method but the problem is it would duplicate on the first string that you entered on the dropdown list if that record exist on your database after you press the space key. I used the code below which duplicates the records on the drop-down list when you type in your string after the space key.
I just want it to be like in any search engine that when you type in the string or your initial string, it will display on the drop-down list all the records from the database that contains the string you entered without duplication. In my case, I'm trying to query a name from my database. This is how it should work, For example, if you type an initial string in the textbox or combo box a named 'Mark', it should display all the names from the database containing 'Mark' into the drop-down list before it changes into its final string that you entered.
Here is the codes I used:
Private Sub ComboBox1_TextChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles
ComboBox1.TextChanged
Dim db As New MultipleDatabaseOperationDataContext
Dim search As String
search = ComboBox1.Text
[Code] .....
I need to load a large txt file that is in a fixed width format. There are over 45K lines, so speed is important.I need to load one of the fields into a dropdown box and have another field (label) display the text of another field in the related line.I could import the file to an access db if needed, but would rather not as i also want the txt file to update from a link on a regular bases. So having it in a DB would be more work to process that part.[code]

View 3 RepliesI would like my gridview to be filtered by the dropdown list I have. It is pulling specific information from the database, so when you choose a value from the dropdown list, it should search through all the records and find only records with the ddl value in them.
The code that I am using in the codebehind for the SelectedIndexChanged is not right though. I get an error message saying 'Value' is not a member of 'Integer'. This is on the line dsCompanyFilter.SelectParameters.Add
It probably has something to do with the gridview not tying to the dropdown list properly, but I am not sure how to fix that code.
