setting cell style to date on ultragrid makes it slow.
posted

I have an unbound coulmn on ultragrid, of type object. On RowInitialize I set the cell style for unbound coulmn to numeric, datetime, dropdownList... depending on anothe coulmns value.

private void gridPropertyInstance_InitializeRow(object sender, Infragistics.Win.UltraWinGrid.InitializeRowEventArgs e)

        {   

long dataTypeId = (long)e.Row.Cells["PropertyDataTypeId"].Value;

 switch (dataTypeId)

            { 

case (long)PropertyDataTypeEnum.DateTime: 

  e.Row.Cells["DisplayValue"].Style = Infragistics.Win.UltraWinGrid.ColumnStyle.Date;

break;  

case (long)PropertyDataTypeEnum.List:

                    e.Row.Cells["DisplayValue"].Style = Infragistics.Win.UltraWinGrid.ColumnStyle.DropDownList;         

break;            

case (long)PropertyDataTypeEnum.Numeric:

                    e.Row.Cells["DisplayValue"].Style = Infragistics.Win.UltraWinGrid.ColumnStyle.Double;

                  break;

            } 

        }

 

This works fine but setting style to Date makes it slow. I have tried removing date styling from rowinitialize to cellclick, which makes loading quick but cell click is slow now.

Is there work around and any other approach that I should go for?

Basically I have an entity with 3 properties : name , displayvalue(string), type.

Ddepending on type displayvalue format can be character, list, numeric, datetime...

On grid I need to display list of entity and should be able to edit displayvalue.

Thanks for help.

    Looking closly into it , realised if displayvalue is empty string, it takes longer otherwise its fine.

    Still don't know how to solve it :(
