[Solved] Cannt change CSS Class of RadNumeric

[Mohamed]

In the design time, I set the CssClass property to "red"

After some event, I try to set it to "yellow", but it doesn't work.



I tried:

TxtAmount.CssClass = "yellow";

Also

TxtAmount.CssClass += TxtAmount.CssClass.Replace("red", "yellow");

plus other ways

Hi,
Try with the below implementation
1) Add the below css style to your page

<style type="text/css">
       .redradnumTxtbox
       {
         background-color:Red !important;
       }

       .yellowradnumTxtbox
       {
         background-color:Yellow !important;
       }
   </style>

Change the css styles as per your requirement

Then apply the 'redradnumTxtbox'  to textbox MarkUp like given below

<telerik:RadNumericTextBox ID="RadNumericTextBox1" runat="server" CssClass="redradnumTxtbox" >
       </telerik:RadNumericTextBox>

 
After this you can change the css class of numeric textbox on button click like given below

protected void Button5_Click(object sender, EventArgs e)
    {
        //Do your task here

        //Set the css class of RadNumeric Textbox
        RadNumericTextBox1.CssClass = "yellowradnumTxtbox";
    }

Hope this helps.
