Windows Forms DataGrid View Clearing Problem
-
Hi, I am using a DataGrid View on my windows forms. I want to clear all the rows of the grid on certain event, for that i tried to set the data source property to null. But it also cleared the columns. I also tried to use the clear function of the rows ut it was of no help; How can i just clear teh rows and let the columns be intact in there. Thanks.

:confused: Clearing a row would surely clear columns too? Can you give an example of what the result you are looking for?

Ok, There are cerain no of rows in the grid, so when i click on the clear button i want that only the column names should be visible but not any rows. And i have aded the columns on the design time, so i want to retain those columns.

Isn't there a Rows collection that you can clear? AFAIK, it shouldn't change the column headers...

You may clear the value in loop using row index and column index; for example: setting null to Row index 0, Column index 0 dgvItemList.Rows[0].Cells[0].Value = ""; I think, u got it. Best of Luck.

Instead of trying to clear the rows on the dataGridView, try clearing the rows on it's data source. lets sat the source of the datagridView is in a DataSet. Lets just make this one up:
this.YourDataSet.YourDataTable. Clear the rows from the DataTable, and the DataGridView will see the changes in the DataTable and reflect the cleared rows. Try this:this.YourDataSet.YourDataTable.Clear();"If an Indian asked a programming question in the forest, would it still be urgent?" - John Simmons / outlaw programmer I get all the news I need from the weather report - Paul Simon (from "The Only Living Boy in New York")

Actually its very simple... grid.datasource = null; grid.rows.clear(); grid.refresh(); and a Indian Programmer gave me the solution by the way.... so if an Indian asked a programming question in the forest .... it will be Urgent.. and i think only Indians can solve it.. no others.. ;P :laugh:
