your error is a big clue, which line of the code does it have a problem with, is it this line:
TextBox1.Text = cClass.dataReader.Item("Type").ToString

yeah i put my class in App_Code folder....should i make dll for my class...i didn't make that....please help me

It depends how your website functions.
Have you previously copied a dll across?
I know that if you write the c# in visual studio and then upload dll then the most updated pages of code must be in that dll
To answer your question then yes put it in the dll

How to select your row?
in your ASP you can do
<ItemTemplate>
<asp:ImageButton runat="server" ID="imgAnnul" CssClass="GridPlaatje" ImageUrl="~/Images/NewDesign/trashcan.png" CommandName="AnnulGrid" AlternateText="Delete" OnCommand="Grid_OnCommand" /><asp:ImageButton runat="server" ID="imgEdit" CssClass="GridPlaatje" ImageUrl="~/Images/NewDesign/pencil.png" CommandName="EditGrid" AlternateText="Edit" OnCommand="Grid_OnCommand" />
</ItemTemplate>
in your code behind you create the method
protected void Grid_OnCommand(Object sender, CommandEventArgs e)
which has the next lines of code
ImageButton btn = (ImageButton)sender;
GridViewRow row = (GridViewRow)btn.NamingContainer;
if (e.CommandName.Equals("EditGrid"))
{
radgrid1.EditIndex = row.RowIndex;
}
else if (e.CommandName.Equals("CancelItem"))
{
radgrid1.EditIndex = -1;
}
else if (e.CommandName.Equals(<name you="" choose="">))
{
}
radgrid1.SelectedIndex = -1;
</name>

Yet you don't use r for anyting. How bizarre.
Why don't you set this up in the aspx instead ?

If you know how many gridview columns there are why not put it in the gridview in the front end code i.e.
<ItemStyle Width="10%" />

i know how many columns and same time i dont like to use databound columns...,
Thats y i said its auto generate columns..,.,
Anyway if u give bound column also its not at all considering...,
Its considering only grid view width...,
according to that its taking its own space for columns
