I'm using Visual Studio 2013 and Telerik UI for WinForms 2015.2.623.40.

I have a RadPageView with 4 tabs, each page view I would like to control my layout with a RadLayoutControl.  In the designer view I setup a RadPageView on my first tab and place various UI elements (RadButtons, RadTextBox, etc. etc.) and everything behaves as expected.  When I go to my second tab and setup a RadLayoutControl, it is almost as if the designer can see the layoutControlItems elements of the RadLayoutControl from the first page while I'm trying to setup the second page.  Not only that but if you do manage to put two RadLayoutControls on various pages, the event handler that deals with the resizing event seems to throw an exception.  Should I be able to use multiple RadLayoutControls in this way?

I've attached images, page1.png shows how I've setup a sample project with a form that has a pageview with four pages and a RadLayoutControl containing a RadButton, RadTextBox, RadRichTextBox, and a RadLabel; in page2.png I've clicked on the top right area and have selected layoutControlItem1 that is contained on the first RadPageView in the RadLayoutControl.

Hi Support,

I have a grid in which I've implemented a custom multi select combo box column which inherits from GridViewComboBoxColumn. The row data for the grid is a business object which contains a list of values which are then mapped as individual column in the grid (satisfying the customer need to be able to create their own fields). The underlying data for my ComboBoxColumn is a list of values. I've implemented a multi-select dropdown which allows the user to select multiple values via checkboxes. The Value property is overridden to show the values in the list as a simple string. The image below shows this:


What I now want to be able do is to filter on the values. "Show me the rows there 'WILSON' appears". Sounds too easy...

The filter options available are No Filter, Null, Not Null and Custom. When I bash together a test project with a ComboBoxColumn I get the full suite of filters. What happened to them for my custom column?

If there was the 'Contains' filter option that I hoped for I'm not sure that it will work properly anyway. The underlying data is a list, not a  single value, so I'm not sure how the filtering would be applied.

I tried using the Excel filtering type (by implementing IGridFilterPopup) but I encountered some errors relating to comparing elements in the list.

I was hoping for some advice/tips on the best way to implement this kind of filter?

Thanks,
Dave

Hi,

 

I have a gridview, one of the columns is time in minutes. I've summed this in the SummaryRow, but would also like to convert it to hours and minutes.

I know how to convert it (as in, I know what I need to do to minutes to get hours) and have this that gives me the total of minutes:

        Me.RadGridView1.MasterTemplate.ShowTotals = True
        Dim summaryItem As New GridViewSummaryItem("actual_time", "Total Minutes = {0}", GridAggregateFunction.Sum)
        Dim summaryRowItem As New GridViewSummaryRowItem()

        summaryRowItem.Add(summaryItem)
        Me.RadGridView1.SummaryRowsTop.Add(summaryRowItem)

Is it possible for me to get the value of so I can then manipulate it before passing it back to the SummaryItem?

Thanks, Shane

Hi,

I've got a gridview which contains a ListView of GridLayouts. In essence the items are made of SimpleListViewVisualItems very similar to the ListView example found in the demo applications for winforms. Instead of using a StackLayoutPanel for presentation, all data is filled into a GridLayout for easier maintenance and readability. How should I proceed to implement export and print functionality?

I thought of exporting row data to images and exporting those images similar to how it is done in a GridView of ChartElements, but GetAsBitmap returns nothing. Here is the relevant code:

 

Private Function GetTextBoxElement(count As Integer) As RadElement
        Dim result As New RadTextBoxElement()
        Dim myText As String = ""
        result.Text = myText
        result.StretchHorizontally = True
        result.StretchVertically = True
        Return result
    End Function

I am sure I am missing something, but unsure of what it might be.

Looking forward to your respons

Hello all,

how can I locate a certain row (or determine a row index) in the virtual grid by looking up a certain value?

If for example I have a list of employees with ID, Name, Address, Phone how can I locate the row with a certain Employee ID?
Also there seems to be no row collection that can be searched using Linq.

Thanks in advance.

Best regards, Ronny

Hi,

I'm using the RadRibbon Form and i have set ApplicationMenuStyle to BackstageView I have added a ListBox on a Tab and when I double click an item in it I want to load a file and show the main form.

I can load the file fine but the BackstageView does not close. How do i get the BackstageView to close?

thanks

I have created a custom theme that is a copy of a standard theme (I exported a .tssp file, made a copy, and started editing the copy). I would like to copy some individual elements from a different them to my custom theme (for example, the RadForm along with it's titlebar icons). So far I haven't been successful in figuring out how to do this. Is it possible? If so, could you list the steps necessary to do it? (I would prefer to keep everything contained in one custom .tssp file if possible.)

Thanks.

Hi,

I can't seem to figure out the right control to use for my task.  I tried RadMaskedEditBox with all type of masking type and RadSpinEditor, but neither can get me what I need.  Here is what I need:

1. This control must allow to enter only numeric values.

2. This control has to be binded to a nullable integer. 

3. This control need to allow me to delete the value leaving it blank, which should assign null to the binded property.  Vice versa, if I set value of the binded property to null, then control should not contain any values.

Any suggestions?

Thank you in advance.

 

I'd like to remove all columns from my grid at run-time and completely rebuild it. I can't do:

            foreach (var column in GridQueue.Columns)
            {
                GridQueue.MasterGridViewTemplate.Columns.Remove(column);
            }

because the Remove changes the iteration and it throws "Collection was modified; enumeration operation may not execute."

Suggestions? thanks.
