Hi, I have a gridview to which I'm adding template fields programmatically. Each of the template fields have a textbox. I would like to make this text box have 2-way binding to a database column. Please see below code.
public class CustomEditItemTemplate : ITemplate
{
private DataControlRowType templateType;
private string columnName;
public CustomEditItemTemplate(DataControlRowType type, string colname)
{
this.templateType = type;
this.columnName = colname;
}
public void InstantiateIn(System.Web.UI.Control container)
{
TextBox tb = new TextBox();
tb.ID = columnName;
tb.DataBinding += new EventHandler(this.tb_DataBinding);
container.Controls.Add(tb);
}
private void tb_DataBinding(Object sender, EventArgs e)
{
TextBox t = (TextBox)sender;
DetailsView dv = (DetailsView)t.NamingContainer;
//This line does only one way binding. It takes the rows from the database and displays
//them in the textboxes. The other way binding is not done. This is why my code fails
t.Text = DataBinder.Eval(dv.DataItem, columnName).ToString();
}
}
I'm calling the above class as follows
tf = new TemplateField();
tf.HeaderText = "My First Names";
tf.EditItemTemplate = new CustomEditItemTemplate(DataControlRowType.DataRow, "firstName");
dvModify.Fields.Add(tf);
How can I make the text box such that when I edit the text, this change is reflected in the database as well?
Thanks for your time everyone
