I also had trouble with the TextBox widths in Firefox, Netscape, and Safari
browsers. I worked around it by deriving a class from TextBox and overriding
the Render method. You could probably do the same to solve your issue with
the controls. Here's the code I used for my fixed textbox:
public class FixedTextBox : System.Web.UI.WebControls.TextBox
{
protected override void Render(System.Web.UI.HtmlTextWriter writer)
{
#region Add Cross Browser Size To Attributes Collection
#region Width
if(this.Width != System.Web.UI.WebControls.Unit.Empty)
{
string WidthString = this.Width.Value.ToString();
#region Append UnitType Symbol
switch(this.Width.Type)
{
case System.Web.UI.WebControls.UnitType.Percentage:
WidthString += "%";
break;
case System.Web.UI.WebControls.UnitType.Pixel:
WidthString += "px";
break;
}
#endregion Append UnitType Symbol
if(this.TextMode == System.Web.UI.WebControls.TextBoxMode.MultiLine)
{
this.Attributes.Add("width", WidthString);
this.Attributes.Add("style", "width:" + WidthString); // Firefox
}
else
{
//this.Attributes.Add("width", WidthString);
this.Attributes.Add("style", "width:" + WidthString); // Firefox
}
}
#endregion Width
#region Height
if(this.Height != System.Web.UI.WebControls.Unit.Empty)
{
string HeightString = this.Height.Value.ToString();
#region Append UnitType Symbol
switch(this.Height.Type)
{
case System.Web.UI.WebControls.UnitType.Percentage:
HeightString += "%";
break;
case System.Web.UI.WebControls.UnitType.Pixel:
HeightString += "px";
break;
}
#endregion Append UnitType Symbol
this.Attributes.Add("height", HeightString);
}
#endregion Height
#endregion Add Cross Browser Size To Attributes Collection
base.Render (writer);
}
}
