Set custom control property value through javascript

Hi,

How to set the property value of custom control through javascript. Below is the code snippet used in my custom control.

[ToolboxData("<{0}:ServerControl1 runat=server></{0}:ServerControl1>")]
    public class ServerControl1 : WebControl
    {
        [Category("Misc")]
        public string SelectedText
        {
            get; set;
        }
     }

Re: Set custom control property value through javascript

You can't set the property value directly, ie using JavaScript (which is on the client) to set the value of the control (which on the server). Without knowing how the control gets rendered, it's difficult to say what you need to do but one possible solution is to set the value of a hidden field and then assign the value of the Form item to the control's property during PostBack.

Both of these example show how to get the value on the client. However, this question is regarding setting the value on the server from the client.

Hi,

The examples shown in the below link is not working.. null is returned always..

Example: alert('<%=ServerControl1.SelectedText %>'); && alert(document.getElementById("ServerControl1").SelectedText );

Re: Set custom control property value through javascript

Theorily speakingyou cannot do thatas what stevenbey's said

However I've got a cluemaybe you can create something like a HiddenField in the event of ChildControlCreated or some event like thatand everytime in the Load event of your controltry to use something like Request.Forms["id of that hiddenfield"] to read out strings included by that hiddenfield and assign to the public propertyAnd you can use js to automatically change the hiddenfield's value
