Hi,

I have created a context menu and i want to show that menu on the selected row only.  What happens currently is if i right click on anywhere in grid other than on the selected row still the context menu is displayed.  I dont want that to happen, context menu should only be shown on the selected row, also i want to show context menu on Column header and on particular cell only.

 Also how can we find current cell selected on right click, and set selected row on which its selected.

Appreiciate a quick response.

Thanks,

Raxit

 

 

I will assume that you are setting the context menu via a style. In that case, I suggest you add a Trigger to the style that checks the IsSelected property and if its value returns true, then you set the ContextMenu.

Thanks Jenny for quick response. 

I am not using any style, i have wrote below code in xaml, <xcdg:DataGridControl.ContextMenu>

<ContextMenu Name="mycontextmenu">

<MenuItem x:Name="menuItemReports" Header="Reports" />

</ContextMenu>

</xcdg:DataGridControl.ContextMenu>

In Code behind file on MouseRightButtonDown event,

 private void dataGridControl1_MouseRightButtonDown(object sender, MouseEventArgs e)

{

if (e.RightButton == MouseButtonState.Pressed)

IInputElement element = gridControl.InputHitTest(e.GetPosition(gridControl));

DependencyObject parent = element as DependencyObject;

If(parent != null)

                {

                    Cell cell = parent as Cell;

                    if (cell != null)

                    {

 .....what happens here is cell is always null, parent object is textblock

 

 Appreciate if you help with a sample code. 

Thanks

Rather than setting the ContextMenu on the grid, you can try creating an implicit style that targets DataRow and that has a Trigger based on the row's IsSelected property in which there is a Setter for the ContextMenu property.

Jenny,

 

I tied the way you mention and it worked thanks for the response.

One more issue, is there any way we can select single column (means column selection), way we select column in table/excel.

I have read few post which says this feature is not available can you throw some light on same.

If availble, which version of xceed grid has that and whats the property i can access.

 Appreciate a quick response.

Thanks,

Raxit

Unfortunately, this is currently a feature that is not support by Xceed DataGrid for WPF.

OK. Thanks for quick reply.

Also by any chance can i get the current column name when user right clicks on column header.

I am using ColumnManagerRow's PreviewMouseRightButtonDown event, the sender is ColumnManagerRow, and not sure how to get the column name/current column name using that columnManageRow.

below is xaml which i am using

<xcdg:DataGridControl.View>

<xcdg:TableView UseDefaultHeadersFooters="False"

ShowRowSelectorPane="True"

ColumnStretchMode="All" ShowScrollTip="True">

<xcdg:TableView.FixedHeaders>

 

<DataTemplate>

<xcdg:ColumnManagerRow AllowColumnReorder="False"

AllowColumnResize="False"

AllowAutoFilter="False"

AllowSort="False"

AllowDrop="False"

 

PreviewMouseRightButtonDown="ColumnManagerRow_PreviewMouseRightButtonDown"

/>

</DataTemplate>

</xcdg:TableView.FixedHeaders>

</xcdg:TableView>

</xcdg:DataGridControl.View>

and in code behind file..

private void ColumnManagerRow_PreviewMouseRightButtonDown(object sender, MouseEventArgs e)

{

ColumnManagerRow x = sender as ColumnManagerRow;

IInputElement element = x.InputHitTest(e.GetPosition(x));

DependencyObject parent = element as DependencyObject;

 

 

}

 

Let me know your comments.

 

Thanks

You could access the cell's ParentColumn property or check the grid's CurrentColumn property.

But sender in below code is always columnmanager not datagrid.

private void ColumnManagerRow_PreviewMouseRightButtonDown(object sender, MouseEventArgs e)

{

ColumnManagerRow x = sender as ColumnManagerRow;

 so cannot get current column/cell.  Any property in ColumnManagerRow to get current column/cell

Raxit

Use the GetParentDataGridControl method to get the parent DataGridControl and from there you can access the CurrentColumn, which may be null if nothing is selected in the grid. Maybe try handling the PreviewMouseRightButtonDown on the ColumnManagerCell type rather than ColumnManagerRow. That way, you could access the parent column through the cell's ParentColumn property.

I was not able to find any such property on ColumnManagerRow / Cell.  Any example code will really help.

My problem on right click on column header i have to check all checkboxes under that column.  Is there any way we can put a check box on header column? searched few post but was not able to get any clue,

 Raxit

The GetParentDataGridControl is a static method defined on the DataGridControl class. The ParentColumn property is defined on the Cell class and therefore inherited by all its derived classes.

Hi,

Context menu is on by default, you can choose to show or hide columns. How would I simply disable the Context menu in XAML code?
