Hi all!!

i Want to edit grid view data using ADO.net. I used this code

C#

protected void GridView1_RowUpdating(object sender, GridViewUpdateEventArgs e)
   {
       objconnection.Open();
       string id= GridView1.DataKeys[e.RowIndex ].Value.ToString();
       GridViewRow row = GridView1.Rows[e.RowIndex];

       TextBox txtUsername1 = (TextBox)row.FindControl("txtUsername");
       TextBox txtPassword1 = (TextBox)row.FindControl("txtPassword");
       TextBox txtStatus1 = (TextBox)row.FindControl("txtStatus");

      objcommand= new SqlCommand ("update Def set username='" + txtUsername1.Text + "' , password='" + txtPassword1.Text + "' , status='" + txtStatus1.Text + "' where username='"+id+"'",objconnection );
      objcommand.ExecuteNonQuery();
      GridView1.EditIndex = -1;
      databind();


   }

it's not changing the data. when i used breakpoint i found that txtUsername1 has the same text that of txtUsername which i used in the item template therefore i am unable to change data.

the problem is that i am not able to access the textbox text that i have used in edittemplate field.

Just a note: ADO.NET is not used to edit anything on the UI. I understand this maybe just words, but it's always good to use accurate wording.

I agree with SA.
I think you did not consider to create an '<asp:UpdatePanel>' with UpdateMode="Conditional". Then in your code behind update such panel before geting the value of such text to save...
