Layered Bar Chart

Does anyone know how to create a layered bar chart like the sample image I have included? I do not want to stack the data because that misrepresents the Y axis value. I am programming this chart for a sales pipeline.

Adding a telerik through codebehind with custom assembly skin is throwing an error

Hi,

I have built a custom assembly skin, and I know that it is working correctly as the controls on the page are showing the correct skin.

However, if I am to add a simple control telerik raddatepicker like the below

protected void Page_Load(object sender, EventArgs e)
{
RadDatePicker oDate = new RadDatePicker();
oDate.Skin = "IWCL";
pnlMain.Controls.Add(oDate);
}

The following error is thrown

Telerik.Web.UI.DatePickingInput with ID='dateInput' was unable to find an embedded skin with the name 'IWCL'. Please, make sure that the skin name is spelled correctly and that you have added a reference to the Telerik.Web.UI.Skins.dll assembly in your project. If you want to use a custom skin, set EnableEmbeddedSkins=false.

I am pretty sure that there isn't any issue with the custom assembly, as without adding a control through a code behind, the page runs ok without any error.

You can reproduce the same error by using the sample project that telerik have provided in the below

https://docs.telerik.com/devtools/aspnet-ajax/styling/controlling-visual-appearance/how-to-load-skins-from-external-assemblies?_gl=1*p0oqmn*_gcl_au*MTU5OTE5Mjc3Mi4xNzIzMjIyMDU5*_ga*ODM2NTIzMjk2LjE3MjMyMjIwNTk.*_ga_9JSNBCSF54*MTcyNzgxODEwNC4yOS4xLjE3Mjc4MjIwNTUuNTAuMC4w

Thank you and I look forwards to hear from you

DatePicker Month Year in Month View Title

DatePicker with Multiple Rows and or Multiple columns the Month View Title isn't honored until you navigate to the next or previous set of months and back, then the Month Year is shown. Or if you click to show the months and select a date, then click to show the dates again, then the Year is shown.

This only seems to be an issue if viewing a single month.

<telerik:RadDatePicker ID="DatePicker1" runat="server" Calendar-MultiViewColumns="3" Calendar-MultiViewRows="2" ShowPopupOnFocus="true"> </telerik:RadDatePicker>

Also applies if using a shared Calendar.

Workaround in prerender

For Each View In Me.rcCalendar.CalendarView.ChildViews
CType(View, MonthView).TitleFormat = "MMMM yyyy"
Next View

[Solved] FormDecorator is not theming scrollbars in a RadGrid

Please have a look at the following demo https://demos.telerik.com/aspnet-ajax/grid/examples/functionality/scrolling/scrolling/defaultcs.aspx?skin=Sunset.

I have a similar scenario of a page with a grid that also has a FormDecorator whose DecoratedControls property is set to All, yet the scrollbars in the grid on this page are not getting styled according to the Sunset theme. If I look at the FormDecorator theming demo at https://demos.telerik.com/aspnet-ajax/formdecorator/examples/overview/defaultcs.aspx then I can see that the scrollbars are being styled by the FormDecorator for the Sunset theme, but I don't see it for the grid scrollbars in my page even though the grid theme is set to Sunset.

<telerik:RadFormDecorator ID="RadFormDecorator1" runat="server" 
DecoratedControls="All" EnableViewState="true" 
ViewStateMode="Disabled" ControlsToSkip="None" EnableAjaxSkinRendering="true" />

When I see the html tag in Chrome's DevTools > Elements, I see the rfdScrollBars class is there as in code below, yet its not getting applied to the grid.

<html xmlns="http://www.w3.org/1999/xhtml" 
class="t-chrome t-chrome129 t-chrome t-chrome129 k-webkit k-webkit129 
RadForm RadForm_Sunset rfdButton rfdScrollBars rfdZone rfdLabel
rfdTextbox rfdTextarea rfdFieldset rfdRadio
 rfdCheckbox rfdGrids rfdRoundedCorners" style="">

[Solved] Can a user control be excluded from RadFormDecorator's action?

I have an aspx page that has a user control with an id of MainMenu. This page also has a form decorator, which is decorating the elements in MainMenu user control.

Is it possible to exclude the user control MainMenu from having form decorator classes being applied to it? If yes, then how would I do it?

<telerik:RadFormDecorator ID="RadFormDecorator1" runat="server" RenderMode="Auto"  EnableAjaxSkinRendering="False"/>
<uc1:MainMenu runat="server" ID="MainMenu"/>

Fill RadDropDownList in Grid with BatchEdit Mode

Hi,

I have the following grid:

<TELERIK:RADGRID ID="RadGridProductCharacteristics" runat="server" AutoGenerateColumns="false" AllowAutomaticUpdates="true" OnItemUpdated="RadGridProductCharacteristics_ItemUpdated" OnItemDataBound="RadGridProductCharacteristics_ItemDataBound" OnItemCommand="RadGridProductCharacteristics_ItemCommand" OnPreRender="RadGridProductCharacteristics_PreRender">
	<CLIENTSETTINGS AllowGroupExpandCollapse="true" />
	<MASTERTABLEVIEW DataKeyNames="CharacteristicID" GroupLoadMode="Client" CommandItemDisplay="Top" EditMode="Batch">
		<BATCHEDITINGSETTINGS EditType="Cell" />
		<GROUPBYEXPRESSIONS>
			<TELERIK:GRIDGROUPBYEXPRESSION>
				<GROUPBYFIELDS>
					<TELERIK:GRIDGROUPBYFIELD FieldName="ParentCharacteristicName" />
				</GROUPBYFIELDS>
				<SELECTFIELDS>
					<TELERIK:GRIDGROUPBYFIELD FieldName="ParentCharacteristicName" HeaderText="Parent Characteristic" />
				</SELECTFIELDS>
			</TELERIK:GRIDGROUPBYEXPRESSION>
		</GROUPBYEXPRESSIONS>
		<COLUMNS>
			<TELERIK:GRIDBOUNDCOLUMN HeaderText="Characteristic" DataField="CharacteristicName" ReadOnly="true" />
			<TELERIK:GRIDBOUNDCOLUMN UniqueName="CharacteristicValue" HeaderText="Value" DataField="CharacteristicValue" />
			<TELERIK:GRIDTEMPLATECOLUMN HeaderText="Color" UniqueName="CharacteristicColor" DataField="CharacteristicColor">
				<ITEMTEMPLATE>
					<%# Eval("CharacteristicColor") %>
				</ITEMTEMPLATE>
				<EDITITEMTEMPLATE>
					<TELERIK:RADDROPDOWNLIST runat="server" ID="RadDropDownListColor" />
				</EDITITEMTEMPLATE>
			</TELERIK:GRIDTEMPLATECOLUMN>
			<TELERIK:GRIDBUTTONCOLUMN UniqueName="ImageButtonDelete" HeaderText="Action" ButtonType="ImageButton" ImageUrl="~/Resources/Images/icon_delete.png" CommandName="Delete" />
		</COLUMNS>
	</MASTERTABLEVIEW>
</TELERIK:RADGRID>

I would like to fill the RadDropDownListColor so it is filled when the user clicks the cell to edit the value.

I checked this article: Column Editors and from there I derived the following code:

protected void RadGridProductCharacteristics_PreRender(object sender, EventArgs e)
{
	GridTableView masterTable = (sender as RadGrid).MasterTableView;
	RadDropDownList radDropDownListColor = masterTable.GetBatchColumnEditor("CharacteristicColor") as RadDropDownList;

	radDropDownListColor.DataSource = DBCom.GetHTMLColors();
	radDropDownListColor.DataTextField = "HTMLColorName";
	radDropDownListColor.DataValueField = "HTMLColorCode";
	radDropDownListColor.DataBind();
	radDropDownListColor.Items.Insert(0, new DropDownListItem("", "0"));
}

But still the variable radDropDownListColor is null.

What am I doing wrong?

Binding DropDownList inside RadGrid using Batch edit mode in code behind

I'm having trouble binding values to a DropDownList inside an ItemTemplate in Batch Edit Mode, I tried looking for the control in RadGrid1_PreRender but it returns a null value, I can't use an SQL Data Source because I'm getting the values for the DDL from a WebService, I'd really appreciate some help with this problem, you can find my code below:

{

}

protected void RadGrid1_NeedDataSource(object sender, Telerik.Web.UI.GridNeedDataSourceEventArgs e)

{

var lista2D = new ExcelInfo(0, 0).OBT_Transformadores_2D();

this.RadGrid1.DataSource = lista2D;

}

protected void cbxPropietarioID_PreRender(object sender, EventArgs e)

{

//Doesn't seem to work             RadComboBox dropDownList = (RadComboBox)RadGrid1.FindControl("cbxPropietarioID");
