Hi

There is a problem in the RadTreeView.

When you rename a node, and the name is longer then the tree’s container width, the tree shakes.

Please try renamning a node with a long name with many ‘a’.

Then rename again the same way, move to a node that has children and the tree will start shaking.

 

Thanks

I subclassed from WPF RadTreeView and created a TreeListView and TreeListViewItem.  I have various controls inside the TreeListViewItem(RadTreeViewItem) that are not functioning properly when I need to interact with them through a mouse drag (ie. selecting text in TextBox, or moving the scrollbar on a combobox dropdown).  The treeview appears to hijack the mouse drag event.  Any ideas on how to fix this? I have attached a jpeg of the control and the problem areas.

Hi ,

I had changed the Control Template of the tree (see the attached picture) but i had defficulties to add the lines. the code below is the tree template:

any suggestions?

The SelectedItem is set properly but does not have the selection brush applied appropriately to its container.

Hi,

I like to add some copy/paste functionality to the grid.
In the grid contextmenu, I need a applicationcommands.copy and a applicationcommands.paste.
The problem is that the copy command is handled by the grid (for clipboard copy I suppose) and the copy canexecute is not fired in my program. Do you have a solution for this?

Thanks in advance,
Thomas.

Hi All,

Are there any built in transition effects in the WPF suite? In the demo, there is a transition between categories of demo's.. the panel pulls back and rotates. Are there any existing control like that available with a choice of transition effects?

Thanks

Hi,
I've some questions about Doughnut customization. I've created in viewmodel a colection with this 3 properties

Color
Item Title
Item Value

I need to set  that properties in the view (xaml) without using code behind. I would like to put Item Title and Item Value in the item tooltip and color in item background.

I attach the code



<telerik:RadChart Background="Transparent" ItemsSource="{Binding PhoneResultBox}" HorizontalAlignment="Stretch" MaxHeight="230">
     
                <telerik:RadChart.SeriesMappings>
                    <telerik:SeriesMapping>
                       
                        <telerik:SeriesMapping.SeriesDefinition>
 
                        </telerik:SeriesMapping.SeriesDefinition>
              
                    <telerik:SeriesMapping.ItemMappings>
                           <telerik:ItemMapping DataPointMember="YValue" FieldName="ItemsCount"> </telerik:ItemMapping>
                 
                            

                        </telerik:SeriesMapping.ItemMappings>
                        
                      </telerik:SeriesMapping>
                    </telerik:RadChart.SeriesMappings>
           
                <telerik:RadChart.DefaultView>
                    <telerik:ChartDefaultView>
                        <telerik:ChartDefaultView.ChartLegend>
                            <telerik:ChartLegend Visibility="Collapsed" />
                        </telerik:ChartDefaultView.ChartLegend>
                        <telerik:ChartDefaultView.ChartTitle>
                            <telerik:ChartTitle Content="Esiti Telefonici"></telerik:ChartTitle>
                        </telerik:ChartDefaultView.ChartTitle>
                        <telerik:ChartDefaultView.ChartArea>
                            <telerik:ChartArea>
                         
                            </telerik:ChartArea>
                        </telerik:ChartDefaultView.ChartArea>
                    </telerik:ChartDefaultView>
                    
                   
                </telerik:RadChart.DefaultView>

             
            </telerik:RadChart>

Hello

I have a three level hierarchy grid
and I want to open all the expand buttons at once (by a button click)
If I use 

RadGridview1.ExpandAllHierarchyItems()
it opens only the first level
how can I open the second level?
I tried to do this

 

RadGridview1.ChildrenOfType<

RadGridView>().FirstOrDefault().ExpandAllHierarchyItems();
but only the children of the first child are open.

Thanks

 

I have a GridView hierarchy with two child tables, of which I want to show only a few chosen columns .

In Q2, it worked fine with the following code.
 

 

GridViewTableDefinition tdPayment = new GridViewTableDefinition();

GridViewTableDefinition tdDetail = new GridViewTableDefinition();

tdPayment.DataSource = MySalePayments = GetSalePaymentsData();

tdPayment.AutoGenerateFieldDescriptors = false;

TableRelation tr = new TableRelation();

tr.FieldNames.Add(new FieldDescriptorNamePair("Receipt", "Receipt"));

tdPayment.Relation = tr;

GridViewDataColumn paymentType = new GridViewDataColumn();

paymentType.UniqueName = "SalePaymentType";

paymentType.Header = "PaymentType";

paymentType.DataType = typeof(short);

GridViewDataColumn amount = new GridViewDataColumn();

amount.UniqueName = "Amount";

amount.Header = "Amount";

amount.DataType = typeof(decimal);

tdPayment.FieldDescriptors.Add(paymentType);

tdPayment.FieldDescriptors.Add(amount);

tdDetail.AutoGenerateFieldDescriptors = false;

tdDetail.DataSource = MySaleDetails = GetSaleDetailData();

tdDetail.Relation = tr;

GridViewDataColumn itemId = new GridViewDataColumn();

itemId.UniqueName = "ItemId";

itemId.Header = "ItemId";

itemId.DataType = typeof(string);

GridViewDataColumn saleQty = new GridViewDataColumn();

saleQty.UniqueName = "SaleQuantity";

saleQty.Header = "Sale Qty";

saleQty.DataType = typeof(short);

GridViewDataColumn unitPrice = new GridViewDataColumn();

unitPrice.UniqueName = "UnitPrice";

unitPrice.Header = "Price";

unitPrice.DataType = typeof(decimal);

GridViewDataColumn discount = new GridViewDataColumn();

discount.UniqueName = "Discount";

discount.Header = "Discount";

discount.DataType = typeof(decimal);

GridViewDataColumn individualDiscount = new GridViewDataColumn();

individualDiscount.UniqueName = "IndividualDiscount";

individualDiscount.Header = "Ind.Discount";

individualDiscount.DataType = typeof(decimal);

tdDetail.FieldDescriptors.Add(itemId);

tdDetail.FieldDescriptors.Add(saleQty);

tdDetail.FieldDescriptors.Add(unitPrice);

tdDetail.FieldDescriptors.Add(discount);

tdDetail.FieldDescriptors.Add(individualDiscount);

radGridViewSalesList.TableDefinition.ChildTableDefinitions.Add(tdPayment);

radGridViewSalesList.TableDefinition.ChildTableDefinitions.Add(tdDetail);

 

When Run in Q3, AutoGenerateFieldDescriptors was simply ignored showing all columns.

In Q3, it was suggested that I use AutoGenerateColumns of GridViewDataControl .
I was able to do it with single child table using DataLoading handler as shown in the demo source code.
But I don't know how to do it with two child tables.

I have implemented a similar search/filter as the scenario found at http://demos.telerik.com/wpf/?GridView/Search , the same behaviour occurs in my own implementation and in the demo itself.

The search while you type works perfectly when a grid row is not selected, however if a row is selected, and a search is started, the row receives the focus.

This occurs only when a matching letter is found within the selected row. The textbox looses focus, which means only the first letter is searched on.

If a match isn't found, the focus remains in the search textbox and more letters can be added to the search.

On a side note, is there any way to ensure the search textbox has the focus when the filter is removed? Eg. When a user deletes his search, the grid immediatly takes focus from the textbox.

Thank you,

A Marshall
