[Solved] Grid Combobox Column

I am binding a radgridview to a datatable the datatable contains a field ‘TankLevel’ that can have one of 5 values ‘1/4’, ‘half’, ¾’ , ‘Full’ or ‘Unknown’ I want to display this column as a GridViewComboBoxColumn and display the value from the underlying datatable and have each of the 5 values available in the comboboxcolumn dropdown. When I bind to the datatable the combobox is populated with the data but combobox in each row has every row available in the dropdown! How can I make each row show the underlying record but irestrict the dropdown to the 5 values n order that the user can select from the other 4 values.

Dim cboCol As GridViewComboBoxColumn = New GridViewComboBoxColumn

cboCol.Name = "cboCol"

cboCol.HeaderText = "Fill Level"

cboCol.DataSource = sVehDT

cboCol.ValueMember = "TankLevel"

cboCol.DisplayMember = "TankLevel"

cboCol.FieldName = "TankLevel"

Me.RadGridView1.Columns.Add(cboCol)

[Solved] Databound RadMaskedEditBox caret position issue

I have a RadMaskedEdit box for phone number entry.

...

Telerik.WinControls.UI.RadMaskedEditBox editPhone = new Telerik.WinControls.UI.RadMaskedEditBox();

...

editPhone.Mask = "(000)000-0000";

editPhone.MaskType = Telerik.WinControls.UI.MaskType.Standard;

editPhone.Name = "editPhone";

editPhone.Text = "(___)___-____";

editPhone.TextMaskFormat = System.Windows.Forms.MaskFormat.IncludeLiterals;

I have defined a Customer class (simplified for this example)

public class Customer {

public string CustomerName { get; set; }

public string PhoneNumber { get; set; }

}

I bind the RadMaskedEditBox Value property to the PhoneNumber property of a Customer object.

Customer editCustomer = new Customer();

...

editPhone.DataBindings.Clear();

editPhone.DataBindings.Add("Value", editCustomer, "PhoneNumber", false, DataSourceUpdateMode.OnPropertyChanged | DataSourceUpdateMode.OnValidation);

After this, when editing the phone number, using the "Del" or "Backspace" key will properly remove the character, but will move the caret to the first position of the text box.

If I remove the Data Binding, the "Del" and "Backspace" keys work as expected. I don't have any event handling code for this control. Currently we are using version 2016.3.913.40.

Is there a workaround, fix, or other change I can implement that will avoid the behavior as I've described?

How to check the checkbox on group header row?

Hello,

I'm using Telerik version 2017 R2 for Winform app.

I have a gridview with "EnableHeaderCheckBox" option is "True".

When I group the gridview by a column A, then click on the checkbox on gridview header row (I meant "Select All" checkbox), please see the picture 1 below

[Picture 1] Click on Select All checkbox

[Picture 2] The result of click on Select All checkbox

As you can see in the result (Picture 2), the checkboxes of group header row is not checked automatically. When I click on the Select All checkbox, it just affects to the children checkboxes in each groups, not the checkboxes on group header row.

How can I check all the checkboxes on group header row when I click on the Select All checkbox?

Please give me an advice! Thanks so much!

[Solved] Printing with different start date overlaps table

Hi,

if you change the

GraphicalViewElement.TimelineStart

of the GanttView to a date inside the range of nodes, to just print a part of the Gannt, the graphical representation overlaps the table.

The expected result should be that the printed timeline gets cut at the TimelineStart, like it correctly does at TimelineEnd.
