I have a GridNumericColumn with bound field.

<telerik:GridNumericColumn DataField="ppds_surf_corp" DecimalDigits="2" 
                            FilterControlAltText="Filter colSurfCorp column"
                            HeaderText="Surface corporelle" ShowFilterIcon="False"
                            UniqueName="colSurfCorp"
                            AllowRounding="True" DataType="System.Decimal">
</telerik:GridNumericColumn>

Example: 2.45678 will still show 2.45678 but I want 2.46. I tried with DataFormatString {0:0.##} and it does't work too.

What's wrong with this code...

Hi Jocelyn,

I couldn't get it to work in my RadGrid when my DataField is a string. I was able to change the value via code in the ItemDataBound event though. I'm not sure why the DataFormatString property was working.

I hope this helps!
Casey

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
{
   if (e.Item is GridDataItem)
   {
      GridDataItem dataItm = e.Item as GridDataItem;
      dataItm["colSurfCorp"].Text = Math.Round(Convert.ToDecimal(dataItm["colSurfCorp"].Text), 2).ToString();
   }
}

Hello,

Here is the sample code that I tried which worked as expected.
aspx:
<telerik:GridNumericColumn UniqueName="UnitPrice" DataField="UnitPrice" DataFormatString="{0:#.#0}"></telerik:GridNumericColumn>

Well, I don't know why but your DataFormating is not working for me. But I tried with a sample project.

This is only a RadGrid showing some columns of the Sales.SalesPerson from AdventureWorks Microsoft DB. I tried your DataFormat on the SalesYTD and it works! But, It doesn't round the decimal. I know this is normal, it's a format string.

What I don't understand is what DecimalDigits stand for if it doesn't affect anything... 

Here is my code:

I don't have anything server side.

Thanks.

Hi Jocelyn,

What is the DataType of the SalesYTD column in the Sales.SalesPerson table?

Are you binding the same way in your project where DataFormatString is not working? If so, what is the DataType of your column, in the database, that the DataFormatString property is not working for? 

The DataFormatString property wouldn't work for me when the DataType from my DataSource was a string. However, if it was a decimal, it would apply the DataFormatString property.

The SalesYTD DB DataType is "money" and in mine everything is String. I am binding the same way except that I am not using a SqlDataSource. I am using a DataTable filled with alot of SqlRequest.

So I guess I'll have to format in code behind inside ItemDataBound?

Is there a way to auto-convert the data bound to the column so that the DecimalDigit apply to the column?

Hi Jocelyn,

I'm not really sure about auto-converting the data bound column to a Decimal Digit.

It looks like you could specify the DataType of the column in your DataTable prior to adding data to it. The following link demonstrates how to add columns of different DataType to a DataTable. Maybe you could try adding a Double, or Decimal column to your DataTable to use for your GridBoundColumn's DataField?

MSDN DataColumn.DataType Property

I hope this helps!
