Hello Syncfusion,

I have a grid with a column of type GridTemplateType like this

<syncfusion:GridTemplateColumn.CellTemplate>
<DataTemplate>
<TextBlock Text="{Binding Code}" VerticalAlignment="Center" />
</DataTemplate>
</syncfusion:GridTemplateColumn.CellTemplate>

<syncfusion:GridTemplateColumn.EditTemplate>
<DataTemplate>
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="Auto"/>
</Grid.ColumnDefinitions>
<TextBox Text="{Binding Code}" TabIndex="0"/>
<syncfusion:ButtonAdv Grid.Column="1"
SizeMode="Small" 
SmallIcon="/oculus;component/Assets/search-24.png"
Margin="0.5,0,0,0"
TabIndex="1"
Command="{Binding Find}"/>
</Grid>
</DataTemplate>
</syncfusion:GridTemplateColumn.EditTemplate>


The problem is each time you ends editing of a cell, although no changes are made, the CurrentCellValueChangedEvent is triggered.

Thanks.

Miquel Juan

Hi Miquel, 
 
Thank you for using Syncfusion control. 
 
In GridTemplateColumn, we can load any controls and we can’t find the triggering of the value changing from that controls. So we have raised the CurrentCellvalueChanged event manually from GridTemplateColumn. 
 
You can  restrict this behaviour by overriding the OnEditingComplete() method in GridCellTemplateRender. Please refer the below code snippet. 
C#: 
  this.sfdatagrid.CellRenderers.Remove("Template"); 
  this.sfdatagrid.CellRenderers.Add("Template",new GridCellTemplateRenderExt()); 
 
   public class GridCellTemplateRenderExt : GridCellTemplateRenderer 
 { 
     protected override void OnEditingComplete(DataColumnBase dataColumn, FrameworkElement currentRendererElement) 
     { 
          
     } 
 } 
 
 
Please revert to us back, if you need further assistance. 
 
Regards, 
Susmitha S
