Hi All,

I have values as 2313 ,546.689,2314.9.

I have rounded off these double values but the result as displaying as

2313,546.7,2314.9.

but I want result as

2313.0,546.7,2314.9.

means if the no is 2313 then it should be display as 2313.0 without changing it .ToString(0.0) coz I have to use it for filtering.

Thanks
