View 4 RepliesI have a DataGridView containing a large number of columns. I want the users to be able to select multiple columns and then select a menu item to hide the selected columns. For example a user might selected columns 5 through 10 and I want the program to hide those columns. I know how to hide columns, one at a time. I can get the count of selected columns but I have not figured out how to get the index to the left-most selected column. Trial and error is such a slow process.
Considering the huge number of options offered by the DataGridView tool, it would be nice if this forum had a special category for the DataGridView (common to VB and C#).
Finally I got the desired results but it took a lot of coding, looping through the selected cells to find the one with the lowest column index, then a second loop to count previously-hidden columns, then a third loop for hiding the selected columns, stepping past previously-hidden columns and declining to hide frozen columns.
i would like to know how i get the selected value of a datagridview combobox column?

I've created this code which transfers the value of the selected Customer ID cell in the datagridview to another form.
Private Sub mnuFileEdit_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles mnuFileEdit.Click
'Define variable for the current selected cell value
[Code]....
It's working fine but at the moment any column in the datagridview can be selected and transferred which causes an error.
So I want to create an If Then statement which confirms that the selected column with the dgv is the PK_ID (customer ID) column before processing the rest of the code. I've tried playing around with "If dgvCustomerSearch.SelectedColumns("PK_ID") Then" but a "Value of type...cannot be converted to Integer" error occurs.

In my datagridview there are two dependent columns, one is category and the other is items. So I want to filter my item column list as per selected category. But the problem is that when I change the category wise data to datasource of items combobox, previous selected items names disappear because previous items is not in current datasource.

View 27 RepliesAdd persistence to multible DataGridView in terms of Hide/Show column and column width
View 1 RepliesIt seems that on clicking datagridview column header, the column will be automatically sorted based on the column type. I have a column showing some numbers. If column type is string, it sorts "1","20","3" into "1","20","3". If column type is double, it sorts into "1","3","20" which is the result that I want. However, there might be some erros in the numbers and error messages(text) will show in the cell instead of numbers. So I cannot set the column type as double. I want to ignore these error messages and sort all the numbers. How can I do this?
Also, I need to add some background colors to different rows in datagridview. So in the column header click event, I call the bkgColor Sub to achieve this. My question is that how can I override the sorting method in this event?

I have:
- Table1 with columns: PK_ID1, LOCATION, DIRECTOR, SELLER, SELLERID, WORKTIME (relationship), WORKCODE
- Table2 with columns: PK_ID2, WORKCODE (relationship) & WORK_DESCRIPTION
My DataGridView do a SELECT * FROM Table1;How can I replace WORKCODE with WORK_DESCRIPTION in DataGridView, please?
Dim Comp = From C In db.Table1 _
Select C.Completed, C.Taken, C.Namne
Datagridview1.DataSource = Comp
Am using the Entity Framework and Columns Completed and Taken are of bit Datatype. When the query results are displayed in the datagridview, these bit columns are returned as of ColumnType Textbox - so i get a Datagridview textbox column with true or false string values.
I want to display Completed and Taken as Checkbox columns (either ticked for True or un-ticked for false) but ofcourse i can't do this in EditColumn dialogue because the Datagridview is unbound.
how can i change this in code at runtime
Is there a way to find the column index of a datagridview column using the columns DataPropertyName?I currently use a loop (shown below in the class) which is kind of ugly, but it works. I'd like to do something like this, which seems more elegant.My goal is this, I store the users DataGridView column settings (i.e. DisplayIndex, Visible, & Width).When the user opens the form that contains the datagridview I want to get those settings from the database and apply the settings to the datagridview.[code]

View 17 RepliesI have a DataGridView (dgv) on a Windows form (VB.NET) which is bound to a datatable. One of the bound columns is a an ID (Foreign Key) to another datatable. All I want to do is Hide the ID column and populate an unbound column with the Name (ParmName) for the user. I searched the foreign value in the datatable and retrieved the information. I set the Value of the cell in the Datarow. All works well, but does not display. The cell accepts the value...I can even Debug.Print the values to the console.

View 3 RepliesI want to have my current row stand out as the current row by virtue of the background color.I also want my current cell stand out from the row color.
in other words i want to controll the background of the current cell as well as the current row, and have these colors different from each other as wel as the background from the non current cells.
I am getting confused with the notion of the current row vs the selected row.I have tried messing with the default row style.selectedbackgroungcolor as well as the same for the default cell style, but cant get it to work the way i want.
i can almost get it if i set the selection mode to full row, but then cannot get the current cell to have a different background color.
