I have a Windows Forms DataGrid currently filled with text.What I want to do is have a ComboBox appear in a cell when the user enters it.After the user has chosen their item from the ComboBox list I want the ComboBox to be removed leaving just their selection as text in the DataGrid, when they leave the cell.
View 11 RepliesI've been programming for a while now and I have a Datagridview which is databound. It pulls up a list of my line items and that works fine. So I have:
OrderID, OrderType, OrderNumber, OrderDescription
Anyhow... these fields all come from the OrderDetails table. I have another table, AllOrders, where one OrderID can have multiple OrderNumbers.
What I need to do is:
1.) The OrderNumber column should be a dropdown list of all OrderNumbers from the AllOrders table where the OrderID matches.
2.) This column should also let users manually type in a value and it saves it to the list.
3.) When the user clicks a save button on the form I need to be able to reference the values from each row to save the selected value to the OrderDetails table.
I thought this would be something rather simple... and I've been pulling my hair out for days. Sometimes I can get the dropdown to load the OrderNumbers correctly, but I can't add one. I can get a ComboBox cell where I can add a value to the list, but I can't load the existing OrderNumbers, etc.
As part of a user interface I'm designing, I'd like the user to encounter the following: when the user wants to edit a value in a cell, the cell in the DataGridView is replaced by a DataGridViewComboBoxCell. This is working now, however, when the user enters the cell (edit cell) the edit cursor stays there, and the combobox won't show. When the user leaves the cell, the Combobox shows, and after again entering the cell and clicking on the combobox, the dropdown finally shows. So 6 clicks are necessary, and I'd like to reduce this to a maximum of two clicks.

I am using vb.net 2010 and winforms and DataGridView. The DataGridView has a DataGridViewComboBox column. When I show the form with the DGV it shows this and empty grid but the column that contains the ComboBox shows the first item on the dropdown list. How can I have the ComboBox display nothing until it is clicked on and selected?

In DGV, I have 2 checkbox columns. Column1 and Column 2. Once I checked a checkbox in a column and it happens that there is already a checked checkbox in the other column and they are in the same ROW. It will automatically disable/uncheck the Checked Checkbox.. Meaning only One CheckBox must be allowed to be marked if happens that they are in the same row.

I would like to create a DataGridView that displays records that fill either 18 or 35 columns. I would like to avoid displaying all 35 columns for all records, instead showing the 17 extra columns on a second row for records that need them.How would I go about this? I'm guessing I need to create a new class that inherits from DataGridViewRow and override it's Paint or PaintCells method, but I have no experience with overriding Paint events, so I'm kind of lost after that.

I have searched the forums for an answer to this problem and while I have found simalar issuses, I have not found a solution that works for me. I have created a dataset and populated it. I know that this is true because I can view the information in the dataset in other ways such as using labels or textboxes. However to display the data in a organized and usable way I would like to display the information in a DataGridView control. I DO NOT need to be able to modify or add anything to the datagridview, JUST view the information there. I am not using any wizards to complete this and so I need to be able to complete everything programmaticly. I have written the code involved to the best of my understanding. When I run the application, there are no crashes or errors thrown, I just can't get the datagridview to populate. Below is the code that I am currently using:
[Code]...
I try to select the last row like this:
Dim lastRow As Integer = DGV.RowCount
MsgBox(lastRow)
DGV.Rows(lastRow).Selected = True
The messagebox returns the correct number, but when it comes to select that row it says:Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index
But if I assign it a row, example: DGV.Rows(5).Selected = True
My code works fine but what I'm trying to do is bind the data without it inserting the column names in the mysql table.[code]
