Workaround for WPF content clutter when dragging the DataGrid scroll bar

In WPF, if a template column is used in a DataGrid, when you drag the scroll bar, the list content appears cluttered. The solution is to assign a value to UpdateSourceTrigger at the time of binding.

    <Grid>        <Grid. RowDefinitions>            <RowDefinitionHeight= "+"></RowDefinition>            <RowDefinition></RowDefinition>        </grid.rowdefinitions>        <ButtonHeight= "All"Click= "Button_Click"Content= "click"Grid.Row= "0"></Button>        <DataGridName= "Dgstudent"AutoGenerateColumns= "False"isenabled= "True"Grid.Row= "1"enablecolumnvirtualization= "True"enablerowvirtualization= "True">            <DataGrid. Columns>                <DatagridtextcolumnHeader= "Name"Binding= "{Binding Name}"Width= "a"></Datagridtextcolumn>                <DatagridtemplatecolumnHeader= "Age"Width= "The ">                    <Datagridtemplatecolumn. CellTemplate>                        <DataTemplate>                            <TextBoxMargin= "5"Text= "{Binding age, Mode=twoway, updatesourcetrigger=propertychanged}"></TextBox>                        </DataTemplate>                    </datagridtemplatecolumn.celltemplate>                </Datagridtemplatecolumn>                <DatagridtemplatecolumnHeader= "Course"Width= "+">                    <Datagridtemplatecolumn. CellTemplate>                        <DataTemplate>                            <ComboBoxMargin= "5"ItemsSource= "{Binding Coursesource}"Text= "{Binding Course, Mode=twoway, updatesourcetrigger=propertychanged}"></ComboBox>                        </DataTemplate>                    </datagridtemplatecolumn.celltemplate>                </Datagridtemplatecolumn>            </Datagrid.columns>        </DataGrid>    </Grid>

The background code is as follows:

     Public classStudent { Public stringName {Get;Set; }  Public stringAge {Get;Set; }  Publiclist<string> Coursesource {Get;Set; } =Newlist<string> () {"C","C + +","C #" };  Public stringCourse {Get;Set; } }    Private voidButton_Click (Objectsender, RoutedEventArgs e) {            varStudents =NewList<student>();  for(inti =1; I <= -; i++)            {                varStudent =NewStudent () {Name= $"Student{i}"                }; Students.            ADD (student); }             This. Dgstudent.itemssource =NULL;  This. Dgstudent.itemssource =students; }
