Control Focus and DataList

[Jerry Camel]

Once the datalist is in edit mode and the text boxes and all happily appear,
how can I force the textbox to be the control with focus, so the user can
start editing without having to click the textbox first? Thanks.

In the past, I have put the following code in the ItemDataBound event of the
text box.

Where TextBoxToFocusId in the text box id in the datagrid

private void DataGrid1_ItemDataBound(object sender,
System.Web.UI.WebControls.DataGridItemEventArgs e)
{
if (e.Item.ItemType == ListItemType.EditItem)
{
TextBox txt = e.Item.FindControl("TextBoxToFocusId");
RegisterClientScriptBlock("DataGridFocus",
string.Format("<script
language=\"javascript\">document.getElementById('{ 0}').focus();</script>",
txt.ClientID));
}
}

Here's the problem... The Datalist control renders the code and assigns IDs
and names to all the controls. So you don't know the name of the control
that needs the focus until the html is rendered. And the name will be
different for every line in the datalist.

For instance, I named the textbox "txtName", but the ID when rendered is
something like "dlEntities__ctl4_txtName" and if I click a different record
to edit, the name would be different. How can you tell what control to set
the focus to?

Thanks.

Per the example below, you on the ItemDataBound event, you can use:

TextBox txt = (TextBox) e.Item.FindControl("txtName");

then txt.ClientID will return the full control name, ie:
dlEntities__ctl4_txtName

Figured it out right after I sent that note. Thanks for the info - much
appreciated.
