Question

How can I get the height of a div which is placed inside a masterpage?

I’m able to set the height as follow:

((HtmlControl)this.Master.FindControl("sidebar")).Style.Add("height", "600px");

Now I’m trying to get the height from my div called mainPage, how can I do this?

Answer 1

MasterPage.Master:

<div id="_test" style="height: 100px" runat="server"></div>

MasterPage.Master.cs:

public HtmlGenericControl test
{
    get { return this._test; }
}

any other cs-file:

string width = ((MasterPage)this.Master).test.style["height"];

Edit: If you want to get any style information created dynamically you will need to store this information into a hidden field, because you won’t be able to retrieve the data by calling style[“x”] in the postback.

Edit2: Adjusted masterpage-name.
