I have a boundfield in a gridview. How can I change the boundfield to a textbox only for a specific column?
I tried
BoundField colname= new BoundField();
grid.Columns.Add(colname as TextBox);
But it goves a cast expression

I'm not sure if this will work for your situation, but you could try using a template field, like this:
<asp:TemplateField>
<ItemTemplate>
<asp:TextBox ID="TextBox1" runat="server" Text='<%#Eval("SomeValue")%>' ... />
</ItemTemplate>
</asp:TemplateField>
EDIT: Adding TextBox to item template from code behind:
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
TemplateField txtColumn = new TemplateField();
txtColumn.ItemTemplate = new TextColumn();
GridView1.Columns.Add(txtColumn);
}
}
public class TextColumn : ITemplate
{
public void InstantiateIn(System.Web.UI.Control container)
{
TextBox txt = new TextBox();
txt.ID = "MyTextBox";
container.Controls.Add(txt);
}
}
EDIT: Setting text of dynamically added TextBox
//get the cell and clear any existing controls
TableCell cell = e.Row.Cells[0];
cell.Controls.Clear();
//create a textbox and add it to the cell
TextBox txt = new TextBox();
txt.Text = cell.Text;
cell.Controls.Add(txt);

I don't know if you can do it with a bound field, but you might be able to add a textbox to a template field from the code behind. Let me check it out and I'll edit my answer.

I dont have template field...I have a bound field inside a grid view which is added to the grid view from code behind.Can you please modfiy my code snippet...im a bit confused...thanks

Can you not use a template field instead? I don't think you can add a TextBox to a bound field.
