[Solved] - DrawCell combine QueryCellStyle event question ?

[The GridLock]

Hi,

my datagrid has some columns, i used query_event to set cells forecolor with values "Yes" in green and "No" in red, also I have used Drawcell_event to number row_header

the problem I encountered was when selecting cells in the same row as in these 2 images:

first click:

second click:

looks like it lost backcolor! How do i avoid this?

Edit: I realize that the problem seems to occur when combining other select sets (extend or multi) to customize the selection

Thanks you!

Hi Khanh Dang,

Thank you for contacting Syncfusion support.

Currently SfDataGrid does not contain a support for when maintain the TextColor when selection applied in datarow. Your requirement can be achieved by override the OnRender method by using GridTextBoxCellRendererExt in SfDatGrid. Please refer the below code snippet,

 

this.sfDataGrid.CellRenderers.Remove("TextBox"); 

this.sfDataGrid.CellRenderers.Add("TextBox", new GridTextBoxCellRendererExt()); 

 

public class GridTextBoxCellRendererExt : GridTextBoxCellRenderer 

{ 

        protected override void OnRender(Graphics paint, Rectangle cellRect, string cellValue, CellStyleInfo style, DataColumnBase column, RowColumnIndex rowColumnIndex) 

        { 

            if (column.GridColumn.MappingName == "Country") 

            { 

                if (cellValue == "Yes") 

                    style.TextColor = Color.Green; 

                else if (cellValue == "No") 

                    style.TextColor = Color.Red; 

 

            } 

            base.OnRender(paint, cellRect, cellValue, style, column, rowColumnIndex); 

        } 

}

Hi Vijayarasan,

what I want to say is that the backcolor of the row is gone, I'll try your solution to fix the forecolor of the text.

Hi Vijayarasan,

maybe because I have chosen Singledeselect as part while using keydown_event. I did not know how it works.
