Activate a text box?

[MattB]

How would I have a textbox on my web form that will automatically have a
blinking cursor in it when the page loads?
Closest I've come so far is having to press tab once to put the cursor in
there.

Thanks!

Hello Matt,

already tried some ClientSide "Action" (javascript -
focus...)?

this is what i use. just pass in the control you want to set focus to. end
of story

/// <param name="control">Control to set the InitialFocus on.</param>
public static void SetInitialFocus(System.Web.UI.Control control)
{
if (control.Page == null)
{
throw new ArgumentException(
"The Control must be added to a Page before you can set the IntialFocus
to it.");
}
if (control.Page.Request.Browser.JavaScript == true)
{
// Create JavaScript
System.Text.StringBuilder s = new System.Text.StringBuilder();
s.Append("\n<SCRIPT LANGUAGE='JavaScript'>\n");
s.Append("<!--\n");
s.Append("function SetInitialFocus()\n");
s.Append("{\n");
s.Append(" document.");

// Find the Form
System.Web.UI.Control p = control.Parent;
while (!(p is System.Web.UI.HtmlControls.HtmlForm))
p = p.Parent;

s.Append(p.ClientID);
s.Append("['");
s.Append(control.UniqueID);
// Set Focus on the selected item of a RadioButtonList
System.Web.UI.WebControls.TextBox rbl = control as
System.Web.UI.WebControls.TextBox;
s.Append("'].focus();\n");
s.Append(" document.");

// Find the Form
p = control.Parent;
while (!(p is System.Web.UI.HtmlControls.HtmlForm))
p = p.Parent;

s.Append(p.ClientID);
s.Append("['");
s.Append(control.UniqueID);
// Set Focus on the selected item of a RadioButtonList
rbl = control as System.Web.UI.WebControls.TextBox;
s.Append("'].select();\n");
s.Append("}\n");

if (control.Page.SmartNavigation)
s.Append("window.setTimeout(SetInitialFocus, 500);\n");
else
s.Append("window.onload = SetInitialFocus;\n");

s.Append("// -->\n");
s.Append("</SCRIPT>");

// Register Client Script
control.Page.RegisterClientScriptBlock("InitialFocus", s.ToString());
}
}
