I have doubt regarding MasterPages & Content Pages...

[Radiv Jeshya]

Hai, I am using Master Pages and content Pages to design my website. Inside the content Page i have Form with textboxes. To validate the text boxes in client side, I am using Jscript. But when controls are placed inside the content page the Id of the controls are changed as follows "txtPwd" to "ctl00_CPH_txtPwd".Due to this i can't able to access the controls in client side. I am inneed of an immediate solution to solve this problem. Can you help me in solving this issue.Thanks in advance.

Can you use validation controls, for validations.

Hi, there is a property for each control called ClientID (see here http://msdn.microsoft.com/en-us/library/system.web.ui.control.clientid.aspx[^]). Use this property while generating the javascript, so that the controls can be accessed by this property. Regards Sebastian

Thank you SeMartens for your immediate response,I would be more useful. If you provide a simple sample about how to access the controls in client side.

How do you attach the validation to the controls? If you have sth like a client-side event attached to the controls you can do sth like this: ASP-Code

myTextbox.Attributes("onclick", "javascript:validateTextbox('" + myTextbox.ClientID + "')");

and the javascript will look like this:

validateTextbox(clientID) {
var control = document.getElementByID(clientID);
// do sth with the control -> validate etc.
}

you can either read it this way document.getElementById("<%=Button1.ClientID%>") or set the master page id in page load of master page like this this.ID = "MyID"; then your control id will be MyID_contentplaceholderid_controlid also keep in mind that clientid wont work in js files

Use document.getElementById ("<%=TextBox1.ClientId%>").value
