Hi,

 I have a simple form as

<form id="form1" runat="server">
<asp:ScriptManager ID="ScriptManager1" runat="server" />
<div>
<asp:PlaceHolder runat="server" ID="tbl_holder" />
</div>
</form>

and code behind as

tbl_holder.Controls.Clear();
Table tbl = new Table();
tbl.Width = Unit.Percentage(98);
tbl.ID = "tbl_ID";
TableHeaderRow tr = new TableHeaderRow();
tr.VerticalAlign = VerticalAlign.Top;
TableHeaderCell tc = new TableHeaderCell();
Label lbl_test = new Label();
lbl_test.ID = "lbl_1" ;
lbl_test.Width = Unit.Pixel(50);
lbl_test.Text = "task 1";
RadToolTip test_tooltip = new RadToolTip();
test_tooltip.ID = "test_tip_1" ;
test_tooltip.TargetControlID = "lbl_1";
test_tooltip.IsClientID = true;
test_tooltip.Text = "test 1 tooltip";
test_tooltip.Position = ToolTipPosition.TopRight;
test_tooltip.Width = Unit.Pixel(300);
test_tooltip.Height = Unit.Pixel(40);
test_tooltip.RenderInPageRoot = true;
test_tooltip.Skin = "WebBlue";
tc.Controls.Add(test_tooltip);
tc.Controls.Add(lbl_test);
tr.Cells.Add(tc);
tbl.Rows.Add(tr);
tbl_holder.Controls.Add(tbl);

The tooltip appears in 100% zoom mode, but If I increase zoom to 125%, tooltip does not appear. I tested in IE11.

Thanks for your help.

Hi,

What is the version of the controls you are using? Old versions may have similar problems because current browsers use decimal numbers for positions and dimensions when zoomed, and old versions of our controls cannot know of this change in the browser behavior.

I advise that you upgrade to the latest and test things again as this should resolve this zooming problem along with several other similar problems related to browser zoom and decimal numbers that we have already fixed in other controls.
