Use a DataGridView instead of a GridView.
Editing should be straightforward, click a cell and start to type.
but its a webapplication..n in web application its a Gridview n not Datagrid...i guess :) plz suggest...

Hey here is my fully functional GridView with edit functionality.
To make gridview editable follow the code in GridViewSiteConfiguration_RowEditing method shown below:
If you are confused of this much of code, don't worry, i will give you simple advice:
The thing is extremely simple:
1. Set the edit index of gridview to new editindex which comes from e argument of the method as follows:
GridViewSiteConfiguration.EditIndex = e.NewEditIndex;2. And after that load the gridview again like this:
loadGridView();3. and don't forget to define the EditItemtemplate in the gridview as i have defined below
Use you brain and make necessary adjustmenst and you will get it
