Custom row style selector refresh rows based on values.

[Vasanth]

Hi,

I have a custom RowStyleSelector applied to SfDataGrid, its functionality is to change background color of certain rows based on some cell values. It works well with initial values. However when user changes those value doesn't automatically change row color. How can I trigger the row style selector update in those scenarios?

Thanks,

Vasanth

Hi Vasanth,

Thank you for using Syncfusion Products.

We have analyzed your query. When changing the value at runtime the StyleSelector is not called and the style is not applied based on the changed value. However you can achieve this requirement by calling the UpdateDataRow method and also by calling the InvalidateMeasureInfo() for visual container in the CurrentCellEndEdit event.

Code Example [C#]:

void datagrid_CurrentCellEndEdit(object sender, CurrentCellEndEditEventArgs args)

  {

        var rowindex = args.RowColumnIndex.RowIndex;

        this.datagrid.UpdateDataRow(rowindex);

  }

We have also prepared a sample based on this and you can download the sample from the below location,

Hi Vasanth,

You can trigger the style selector when you changed the cell value by using UpdateDataRow method in WPF  like in WinRT.
Please find the sample for WPF platform from the following location,

Please refer the below KB document to change the cell value at runtime,
