ItemHeight property

I can't seem to recreate the treeview example that shows a layout having nodes with different ItemHeight values. The RadTreeView seems to only respect the ItemHeight that is set at on the treeview itself and not the values of the child nodes. Is there a flag some where to respect the different nodes property values?

Problem with custom sorting

Hello Support,

I am having trouble with custom sorting accessing values that were set using cellformatting(). I have a Gridview that is databound to a custom class, AutoGenerateColumns = false, adding columns using grid.MasterTemplate.Columns.Add(), using CellFormatting() to populate the data on some of the columns that are not in the custom class.

Values that are assigned from the databound class show up ok, but the Values that were assigned using CellFormatting() are always null.

How can I access the values set using CellFormatting() { e.CellElement.Text = "X"} ?

Thanks

void grid_CustomSorting(object sender, GridViewCustomSortingEventArgs e)

{

foreach (var descriptor in e.Template.SortDescriptors)

{

if (uicomponents != null && !String.IsNullOrEmpty(descriptor.PropertyName) )

{

var customcolumn = uicomponents.FirstOrDefault( ui => ui.FriendlyName.Equals(descriptor.PropertyName));

if (customcolumn != null)

{

int result = 0;

System.Diagnostics.Debug.WriteLine(descriptor.PropertyName);

try

{

//var cellValue1 = (string)e.Row1.Cells[descriptor.PropertyName].Value;

//var cellValue2 = (string)e.Row2.Cells[descriptor.PropertyName].Value;

var cellValue1 = (string)e.Row1.Cells[descriptor.PropertyIndex].Value;

var cellValue2 = (string)e.Row2.Cells[descriptor.PropertyIndex].Value;

if (cellValue1 == cellValue2)

{

result = 0;

}

else if (cellValue1 != null)

{

result = 1;

}

else if (cellValue2 != null)

{

result = -1;

}

catch

{

}

e.SortResult = result;

e.Handled = true;

return;

}

else

{

//Check here if the value for cells that are databound are populated.

var cellValue1 = (string)e.Row1.Cells[descriptor.PropertyIndex].Value;

var cellValue2 = (string)e.Row2.Cells[descriptor.PropertyIndex].Value;

//This actually works.

System.Diagnostics.Debug.WriteLine(cellValue1 + " " + cellValue2);

}

e.Handled = false;

}

[Solved] Insert HTML text into existing RadDocument

Hi Telerik forum,
I began to use the RichTextEditor to create programmatically a radDocument (so i use the paragraph, span, section object to create it).
Once the document is shown, users can insert formatted paragraph to personalize the document. The html text paragraph are stored in database in html format.

The thing i need is to be able to insert formatted html paragraph into this raddocument already generated.
My problem is to evaluate all the html text (with differents tags inside it, span, table, tr etc). I use the HtmlFormatProvider that works perfectly but it produce a new raddocument. So i tried to convert the htmlformatprovider document into a DocumentFragment, but i have to use fragment.EnumerateChildrenOfType(Of object) and explicitly specify the object type (what i wouldn't do).
What's the best approach to insert html text into an existing raddocument ?

Thanks for your help, hoping that my question is clear.

Here's my sample code :

Dim document As New RadDocument

Dim section As New Section

Dim p9 As New Paragraph

Dim presta1 As New RadDocument

Dim msgHtml = New Html.HtmlFormatProvider

presta1 = msgHtml.Import(

"<SPAN><STRONG>Table content :</STRONG></SPAN><TABLE STYLE='border:1px solid black'><TR><TD>Marque</TD><TD>Type</TD><TD>N° série</TD><TD>Fluide</TD></TR><TR><TD>-</TD><TD>-</TD><TD>-</TD><TD>-</TD></TR><TR><TD>-</TD><TD>-</TD><TD>-</TD><TD>-</TD></TR></TABLE>"

)

Dim fragment = New DocumentFragment(presta1)

section.Blocks.Add(fragment.EnumerateChildrenOfType(Of Table).ToList.First) 'its working but only with Table tag

'Saut de ligne

section.Blocks.Add(New Paragraph)

document.Sections.Add(section)

return document

[Solved] RadRibbonBar...RadSplitButtonElement: different behavior in different versions

The following sample code creates a RadRibbonBar\RibbonTab\RadRibbonBarGroup\RadSplitButtonElement UI structure.

Clicking on the radSplitButtonElement1 button causes the click handler (radSplitButtonElement1_Click) to be called twice.

Tested in R3 2017. This is not how it worked in Q1 2013, where the handler was called once.

Is this a bug or an intended change in behavior?

using System.Diagnostics;

using Telerik.WinControls.UI;

public partial class RadForm1 : RadForm

this.radSplitButtonElement1.Items.Add(mni1);

this.radSplitButtonElement1.DefaultItem = mni1;

mni1.Click += radSplitButtonElement1_Click;

RadMenuItem mni2 = new RadMenuItem("item2", 2);

this.radSplitButtonElement1.Items.Add(mni2);

mni2.Click += radSplitButtonElement1_Click;
