I have a DataSet that contains 1 DataTable, and the DataTable contains only 1 row of data. I want to loop through all columns in that row and say:
Column name = column value
so for example if the column name is FAVORITE_FOOD and the value is pizza, I should display FAVORITE_FOOD = pizza I can get the column name from column.ColumnName and the value from Rows(0).Item(0), but for the life of me I can't put it all together in a simple loop.

I have added an unbound checkbox column to my DGV. I have two questions on handling it:
1. How to have a checkbox on this Column header, which on checking must check all the rows in the DGV and vice versa?
2. How do i get the Boolean value of the checked rows in DGV on event handling? In other words, how do i know what rows are selected?

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?
Private Sub DataGridView1_ColumnHeaderMouseClick(sender As Object, e As System.Windows.Forms.DataGridViewCellMouseEventArgs) Handles DataGridView1.ColumnHeaderMouseClick

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

I have a DataGridView, bound to a dataset. All the columns are sortable (.ColumnSortMode.Automatic). The user may change data in certain columns, although not the first ("key") column. When data gets changed on a row, I change the backcolor for that row (to show it as dirty). At some point, the user will do something with all of these changes.
My problem is that I still want the user to be able to resort the data by any of those columns. When it's sorted, though, I lose the backcolors that I changed. I do know which rows are dirty, this is just a cosmetic issue. Isn't there a way to retain those backcolors, or any other such row attribute?

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]

Is there a way to make a DataGridView's column a combo ONLY in the "new row", and a read only textbox in all other rows? I want the user to be able to make a selection from the combo box, and when the row is finished and the "new row" moves down one, I want the column to become a textbox containing the what the user selected. My grid will be bound to a table witch contains a "category" column, that is drawn from a seccond table that i want the combo box bound to.

I have three sub tables that I want to process. For each I want to combine the rows, as they are only different by contents in the second column(I want to do the same to the fourth column, later):
'Sub table 1
xx|C201 |02300877 |Samsung |....
xx|C201 |02300877 |Toshiba |....
xx|C213 |02300877 |Samsung
[code]....
p.s. For the fourth column, Manufacturer information , I want to do the same and I'd probably get something like this for the final table:
xx| C201,C213,C606,C619 |02300877 | Samsung
xx| C201,C213,C606,C619 |02300877 | Toshiba
xx| C303, C305,C712 |02301163
xx| C207, C209, C708 |02301165

I have the following code to add a new column into the datagridview but how to default value to this column?
I do not want to use for loop to loop through each row and get the column updated, is there any other way?
I want to default them to 'N' and i will have the code to change it to 'Y' subsequently based on conditions.

I have a db with Column name Break. I have attached to my datagrid view and all that works and shows up correctly. However Im needing to put this code in a timer to get all the times in the Break Column but I need to get it from each and every row. For example:
Break
6:00am
7:00am
6:30am
I need it to look through each row and get that value. Ive tried various things, but Im not on my normal computer so I cant post my code.
