[Solved] can't disable datepicker with Attributes.add

[Sandra]

I am trying to disable the datepicker after a postback. 

For other objects I can use something like the following to hide a control:

nameofControl.Attributes.Add("STYLE", "Display: None")


Is there any code I can use to disable the radDatePicker after a post back?

I tried the following with no success.

nameOfDatePicker.Attributes.Add("dateInput", "disable")

Hello Sandra,

I would recommend you use the following approach:

RadDatePicker1.Enabled = False

if you want to disable the nested DateInput only:

 RadDatePicker1.DateInput.Enabled = False

That works, but then I can't disable it upon clicking another option button.

Here is what I am trying to do:
I need to enable or disable the raddatepicker based upon options selected.  But in order to not hit the server and be faster, I have a Javascript function that gets run when an option button is clicked.  This function enables/disables the raddatepicker

But then after a post back when they are submitting some information, the date picker is always enabled, when sometimes it should not be.  When I do as you suggest, it does correctly reset the datepicker to disabled after the postback.  But then when I click the option button again, the raddatepicker should become enabled, but it does not.

Hello Sandra,

Another approach is shown below:

protected void DisableButton_Click(object sender, EventArgs e)
{
    string myScript = "Sys.Application.add_load(function() { $find('" + RadDatePicker1.ClientID + "').set_enabled(false); });";
    ScriptManager.RegisterStartupScript(Page, typeof(Page), "myScript", myScript, true);
}

You can then enable/disable it on the client using the set_enabled javascript method.

When I look up your suggestion on the internet, it says in order to do this, the control that I put it on the click even of, has to be on an update panel.  But I do not want it on an update panel as I am tring to only use Javascript for speed, or recapture the input after postback.  Is that true, that the control has to be on an update panel?

Also, I am having another problem with the line:

ScriptManager.RegisterStartupScript(Page,

typeof(Page), "myScript", myScript, true)

 

It gives an error:
'Is' expected
and the error is on the comma after the typeof(Page)

No, you need the ScriptManager control only.

Also, I am having another problem with the line:
ScriptManager.RegisterStartupScript(Page,
typeof(Page), "myScript", myScript, true)
Please find my example, attached to this post.
