how can i clear gridview

[Herman T Instance]

sounds like you have a refresh problem. Is your gridview in an updatePanel? Is the gridview DataBound after set to null ? gridview.DataSource = null; gridview.DataBind();

Hi RajKumar, adap.Fill(ds,"table1"); ds.Clear();Clear the dataset and Then fill another data and bind to the gridview

[Blue_Boy]

if you have AutoGenerating Columns then just change the DataSource example: GridView1.DataSource = datasource GridView.DataBind(); GridView1.DataSource = newdatasource GridView.DataBind(); if you are using BoundFields then I will sugest u using new GridView control for new datasource

I Love T-SQL

can u tell me how to delete complete data only from data table before adding data to it ?

[Vijayitsb]

if you delete row use this code. dt.Rows[Index].Delete() Or if u want delete data dt.Rows[Index]["ColumnName"] = null;

Thank & Regards Vijay s

simply bind the gridview without specifying the datasource...data will get vanished
