Thanks for quick reply. 

I have changed the browser property to XML but problem is still there.

Whether I am missing some thing ?

Raju,

 Do you know if infragistics 7.x has this issue?

Try removing all the inline styles on aspx page for the grid --rowstyledefault and rowalternatestyledefault. Then only set the cssclass on server side.

Ner..I tried that before definitely didn't fix it.

 Hey cliffl, Currently I am using Infragistic grid version 7.3.0.0

 I am not sure about other versions...

 Thanks mateia !!! It's working now.

 In my code problem is order of .css class style and  .cs apply order.

For any one else, order should be always like following  -  

.cs

this.UltraWebGrid1.DisplayLayout.RowStyleDefault.CssClass = "RowStyle";
this.UltraWebGrid1.DisplayLayout.RowAlternateStyleDefault.CssClass = "RowAltStyle";
this.UltraWebGrid1.DisplayLayout.HeaderStyleDefault.CssClass = "HeaderStyle";

and in .css

.RowStyle{background-color:Blue;}
.RowAltStyle{background-color:White;}
.HeaderStyle{background-color:Green;}

Hey Guys,

I have found an alternate ways but not sure whether I am correct or not ...

I have commented the below line

UltraWebGrid1.DisplayLayout.RowStyleDefault.CssClass = "cssOddRow";

and added the following

UltraWebGrid1.DisplayLayout.FrameStyle.CssClass = "cssOddRow";

Now it applies Header style, Alternate row style correctly and for rest of the frame it will take cssOddRow style.

But I am not sure whether it's a correct way ....

Thanks shareeef !!!

Setting OptimizeCSSClassNamesOutput property to false prevents odd rows to take header style.This code resolves my 50% problem.

But Issues are still there. I have to apply different CSS for odd and even row. Following is the code :

UltraWebGrid1.DisplayLayout.RowStyleDefault.CssClass = "cssOddRow";

UltraWbGrid1.DisplayLayout.RowAlternateStyleDefault.CssClass = "cssEvenRow";

The above code by default take cssOddRow style for all rows.

Any solution ?
