i am creating a custom control for the textbox.Let say when the textbox's action is edit , the textbox will render as textbox .On the other hand , when the textbox is action is view, then
textbox will render as label.But now i got a problem , how can i validate my textbox with the required field validator when the textbox's action is edit?Here is my coding
[ToolboxData(@"<{0}:cusTextBox runat=""server"" Action=""Edit"" />")]
public class cusTextBox:TextBox
{
public string Action
{
get
{
String s = (String)ViewState["Action"];
return ((s == null) ? String.Empty : s);
}
set
{
ViewState["Action"] = value;
}
}
public override void RenderControl(HtmlTextWriter writer)
{
if (Action ==gbcCommandVariable.CommandEdit)
{
base.RenderControl(writer);
}
else if (Action == gbcCommandVariable.CommandView)
{
writer.Write(String.Format(@"<span ID=""{0}"" style=""display:inline-block; white-space:inherit"" >{1}</span> ", this.ClientID, this.Text));
}
}
}
My suggestion would be to set some code checking the custTextBox1.Action property. When View set RequiredFieldValidator1.Enabled = false else Enabled = true.

Hi, did u got other better suggestion?because i may have many RequiredFieldValidator1 in my webform application. It causing me alot of coding. Btw thanks for your suggesion
That was the quick and dirty suggestion, the more correct suggestion would be to build it into your custom textbox control. This would involve quite a bit of coding as well but would only be one time. In there you can check to see if your Action property
is set to and add or enable/disable the validator there.

Otherwise you can create your custom validator control, overriding the render method to check the condition, and using it insted of normal RequiredFieldValidator.

In my mind，I think if you only want to do validations to check whether the TextBox is empty or not，Just Do checks in the RenderControl by checking the Text property inherited from TextBox control，Something like this following：
if (Action ==gbcCommandVariable.CommandEdit)
{
base.RenderControl(writer);
if(Text=="")
{
//Do what you want here....
}
}
