I have a datagridview (dgv) and if the user changes the size of a column or moves the column to the left or right, I want to be able to save those changes, so when the user sign's on again, the dgv will show as it was when the user closed out of it. Is there a way to do this?Also, is there a way to "freeze" columns? For example if I have 10 columns, I freeze column's 1 and 2 (to the left) so whenever the user scroll's over to the right, column's 1 and 2 will stay on the screen.
It 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 a datagridview with three columns. i set the first column to visible=false, so the user can only see two columns.when the user presses the tab key in the first visible column -- column(1), i want to ignore column(2) so that the user only tabs through the rows in column(1)i can't get it to work. it will always tabs through the rows in column(2) even if i use the column name.
In my window application i have taken one combobox field with its collection as "amc", "war" etc. Now in my datagridview this combobox column is display as Textbox column, i want to change it to combobox with the above collection "amc","war". I have retreiving the result in datagrid through sql query, hence in datagrid edit column section we doesnot have that part to change to Combobox column.

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.
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]
I have a data gridview on my windows form with 4 columns. Now I identify a column as followed:
Dim item1 as String = DataGridView1.Item(1, index).Value
So now I use a number ( In this case: 1 ) for the column index, but I want to make it a bit more readable so now I want to obtain the column index based on the datagridview column name.[code]...
I want to move the cursor from column 1 to column 4 but what happened instead the cursor moves to column 5, this happens when I use the enter key event. but run well if I double click. The following description of the program: there are 7 columns of code, item description, unit, price, qty, discount, item amount code when key enter press :
Some codes here on how could I validate my datagridview? I mean, a certain column on my datagridview should accept integers only, otherwise, it will return a messagebox. Kindly include on which event it should be posted.
I 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. They are there just nothing displaying in DataGridView. Nothing odd about DataGridView. Should be straight forward...
My Code , Dim dtParm As DataTable = MyDataSet.tblParameter Dim dgv As DataGridView = Me.dgvResultNum_DataGrid
am trying to calculate the values in rows in column 6 based on values of column 5. Bellow is the the code I am using I get a run time error about the string not formatted properly
But this code will add columns to every rows in the gridview. How can I change the code so that it only add the column to row one instead of every row?

I want to sum of two coloum in Database but show the only single Record but when i use Distnict keyword in a Query that time this query will not effective .....
How to set the datagridview to have columns always well fitted to the actual widht of the datagridview? And also I need last column of it to be alligned right and to take circa about 10% of the actual width?The columns before last should act like usually last one acts, and should fill all free space left throwing the last column to tie right side.detect on Mouseup when column is being resized not cell clicked?
I have probably not a unique issue but I can't seem to figure it out. I need to calculate a datagridview column after it a new row has been added to it. I am adding the row to the datasource and the row is added to the datagridview but how can I automate the two thing together by a single button click. IE: add the row (with a value)to the gridview and then calculate. I have this code but is doesn't work.
