C# DataGrid clearance issue.

I want to clear the DataGrid that I am using.

This is the code I am currently using:-

C#

DataGrid.DataSource = null;
DataGrid.Rows.Clear();

It only works the first time it is used, although it removes the header when the record is updated.

Please can someone suggest where I am going wrong.

Don't be rude. It isn't up to us to sort out your problem.

Please Sir, show more code than this. This is an unsolvable puzzle with just 2 lines of code. The problem moght be other code, perhaps an if statement or so.

That looks fine, are you re-assigning DataGrid somewhere?

Bala Selvanayagam 6-Oct-11 7:35am

try this

ds1.Tables[0].Clear();

ds1 is the Dataset bound to the grid

How do you know that? There is no source given that shows it. He might use a datatable object directly or an sqldatareader or a dataview

Member 8164209,

Are you able to post the code showing how you are attaching the data to the grid ?

Solution 2

You should use DataGridView control instead of DataGrid.
The DataGridView control replaces and adds functionality to the DataGrid control,
and your code works perfectly with it.
