In my ASP.NET Web Forms project on Visual Studio 2010, I have three HTML server controls stacked vertically in the browser. The challenge is to dynamically adjust the size of the third control based on the number of items within the second control (which is determined in the C# code-behind). How can I change the size of the second web server control dynamically depending on a condition evaluated in the C# code behind? Thank you.
By setting the number of items in the C# code-behind, you also have the ability to adjust the size programmatically. For instance, if your control containing items is a DropDownList and the control requiring resizing is a TextBox, you can achieve this through C# code:
TextBox1.Style["Height"] = DropDownList1.Items.Count.ToString() + "px";
