Introduction:
In this artcle we will discuss about how to edit gridview rows.

Main:
In Gridview,normally we used OnRowEditing Method for editing rows,
The Common syntax for editing gridview row is,

<asp:GridView OnRowEditing=”GridViewEditEventHandler” />

Add,one gridview with rowediting declaration,

 <asp:gridview id=”SampleGridView”
        datasourceid=”sample”
        autogeneratecolumns=”true”
        autogenerateeditbutton=”true”
        allowpaging=”true”
        datakeynames=”ID”
        onrowediting=”GridView_RowEditing”  
        runat=”server”>
      </asp:gridview>

In GridView_RowEditing method,

public void GridView_RowEditing(Object sender, GridViewEditEventArgs e)
  {
 
    String name = SampleGridView.Rows[e.NewEditIndex].Cells[6].Text;

    //We allowed users to edit if the condition is true
    if (name == “Jimmy”)
    {
      SampleGridView.EditIndex = e.NewEditIndex;
      BindData();     
    }
    else
    {
      e.cancel=true;
    }

  }

Conclusion:
Hope,this helps,
Happy Coding.
