Hello there,

I am facing system.StackOverflowExcepiton while exporting document with HtmlFormatProvider. I am attaching my code with the HTML string which I am passing into RichTextEditor.

---------------------------------------------------------

HTML String:

"Navigate to the <a href="https://exelon.ifs.cloud/landing-page/" target="_blank"><b><u>IFS Cloud Landing Page</u></b></a>.<br /> <br />NOTE: If the above link does not work for you, copy and paste this address ...<br /> <br /><u>https://exelon.ifs.cloud/landing-page/</u>"

Method which is giving me an error:

3. The charts are not displayed and the following error occurs:

Auto-complete items overlap in the VisualStudio2022 theme:

We are using the DropDownButtonElement on a RibbonBar, there are a very frustating issue with the RadArrowButtonElement.

On this image it show 5 children, but on code there are 6 children, here is a CopyPase of your  CreateChildElements in RadArrowButtonElement.

    protected override void CreateChildElements()
    {
        arrow = new ArrowPrimitive(ArrowDirection.Down);
        arrow.Class = "RadArrowButtonArrow";
        arrow.AutoSize = false;
        arrow.Alignment = System.Drawing.ContentAlignment.MiddleCenter;
        overflowArrow = new OverflowPrimitive(ArrowDirection.Down);
        overflowArrow.Class = "RadArrowButtonOverflowArrow";
        overflowArrow.AutoSize = false;
        overflowArrow.Alignment = System.Drawing.ContentAlignment.MiddleCenter;
        overflowArrow.Visibility = ElementVisibility.Collapsed;
        fillPrimitive = new FillPrimitive();
        fillPrimitive.Class = "RadArrowButtonFill";
        fillPrimitive.AutoSizeMode = RadAutoSizeMode.FitToAvailableSize;
        borderPrimitive = new BorderPrimitive();
        borderPrimitive.Class = "RadArrowButtonBorder";
        borderPrimitive.AutoSizeMode = RadAutoSizeMode.FitToAvailableSize;
        imagePrimitive = new ImagePrimitive();
        imagePrimitive.Class = "RadArrowButtonImage";
        imagePrimitive.AutoSizeMode = RadAutoSizeMode.FitToAvailableSize;
        imagePrimitive.Alignment = System.Drawing.ContentAlignment.MiddleCenter;
        textPrimitive = new TextPrimitive();
        textPrimitive.Class = "RadArrowButtonTextGlyph";
        textPrimitive.AutoSizeMode = RadAutoSizeMode.FitToAvailableSize;
        textPrimitive.TextAlignment = System.Drawing.ContentAlignment.MiddleCenter;
        textPrimitive.StretchHorizontally = true;
        textPrimitive.StretchVertically = true;
        Children.Add(fillPrimitive);
        Children.Add(borderPrimitive);
        Children.Add(arrow);
        Children.Add(overflowArrow);
        Children.Add(imagePrimitive);
        Children.Add(textPrimitive);
    }

The problem is that we are changing the ArrowButton size to (6, 0) width, here is the how it looks:

As you can see the triangle is outside the ArrowButton, my first idea was to look the ArrowPrimitive and OverflowPrimitive, but that triangle is on TextPrimitive.

Making this change on RadDropDownButtonElement i was able to "solve" the offset and the size.
base.ArrowButton.TextPrimitive.Font = new Font(base.ArrowButton.TextPrimitive.Font.FontFamily, 6);

I have to comment this to something like: "I dont know why this works, but the triangle is on a child text primitive... So don't erase this line".

When Telerik UI for WinForms / WPF extensions are installed, Visual Studio is unresponsive for a couple of minutes after a solution is loaded. During that time, "Updating source control status…" is shown.

Workarounds:

• Disable Telerik UI for WinForms / WPF extensions.
• Checkout the solution file.

Setting the Title property should update the header text:

 this.radPageViewPage1.Title = "test";

This bug is about a mismatch between what behaviour is expected (on a functional level) and the actual behavior. There are different scenario's:

A normal example without a bug

int index = myRadGridView.Rows.Add(1, 2, 3); 

Actual and expected behavior

Adds a row to the grid, filling cells with the values 1, 2 and 3. Even when there are more columns than values, only the first 3 cells are filled.

Bug #1

int index = myRadGridView.Rows.Add(); // Will result in: myRadGridView.Rows.Add(new object[0]);

Actual behavior

IndexOutOfRangeException is thrown.

int index = myRadGridView.Rows.Add((object[])null);

int index = myRadGridView.Rows.Add(new GridViewDataRowInfo(...), new GridViewDataRowInfo(...));

// or

int index = myRadGridView.Rows.Add(new object[] { new GridViewDataRowInfo(...), new GridViewDataRowInfo(...) });

Repro-steps

1. Create a RadGridView
2. Add a GridViewDecimalColumn
3. Add a GridViewSummaryRowItem with a GridViewSummaryItem which:
   1. calculates the average of the values in the decimal column
   2. formats the value to two decimals after the decimal point: {0:0.00}
4. Make an event handler for ViewCellFormatting.
5. Add some rows with values to the grid.
6. In the event handler, try to read ((GridSummaryCellElement)e.CellElement).Value.

Actual behavior

The value contains a string representing the formatted and rounded value of the average of all values.

Expected behavior

The value contains a raw, not rounded,  not formatted, decimal value. 

Remarks

I expect this behavior since GridSummaryCellElement has two properties: Text and Value.
I expect those to have difference functions. Value to hold the actual calculated value, and Text to hold the formatted, round string-equivalent.

Another reason why I expect this, is that Value is of type object, not of type string. So expect a value corresponding to the original datatype of the column and/or the result of the calculation.

Follow-up questions

1. In what scenario may I expect in Value another data type that string?
2. How, during the event handler, can I retrieve the original calculated value (with using parsing, since that is slow and does not contain all the digits).
