I have an imagebutton column:

<telerik:GridButtonColumn CommandName="MyCommand" ButtonType="ImageButton" UniqueName="ViewNote">

</telerik:GridButtonColumn>

The image is not displaying, but 'Submit Query'.

I read somewhere this was because the URL was wrong, however my URL to the image is the same as the URL's to all the images on that page.

Any ideas?

If (TypeOf e.Item Is GridDataItem) Then

Dim dataItem As GridDataItem = CType(e.Item, GridDataItem)

If (dataItem("FileStatus").Text = "Requested") Then

dataItem.ForeColor = Drawing.Color.Crimson

dataItem.Font.Bold = True

CType(dataItem("ViewNote").Controls(0), ImageButton).ImageUrl = "../images/time_icon.jpg"

Else

dataItem("ViewNote").Controls(0).Visible = False

End If

RadNumericTextBox.set_value() doesn´t change value at all (ClientSide)

Hello everybody,
I had two RadNumericTextBox TextInicio & TextFin (initial text and final text).
The rule here is:
The value in TextInicio can not be bigger than TextFin and viceversa.

So I created a function to check values entered by the user. If one of these values break this rule then it will be necesary to change its value to correct this situation.

The thing is that set_value() is not working; the value remains unset.

I also debugged it with Firefox Developer Tools.

NOTE: Min and Max values are set on server side at page´s Load method. But they usually goes from 1 to 2000.

Are there any others factors I have to take under consideration?
Any ideas about what could be the cause of this??

Am I doing something wrong? If you need something else please let me know.

Here is the code in my page.

03. <script type="text/javascript" id="telerikClientEvents1">

04.//<![CDATA[

05.

06. function checkValues(sender, args, isInitial) {

07. var txtIni = $find("<%=TextInicio.ClientID%>");

08. var ini = txtIni.get_value();

09.

10. var txtFin = $find("<%=TextFin.ClientID%>");

11. var fin = txtFin.get_value();

12.

13. if (ini > fin) // if initial is bigger than final then it is necesary to adjust a value

14. {

15. if (isInitial) // which value will be set

16. {

17. txtIni.set_value(fin);

18. }

19. else

20. {

21. txtFin.set_value(ini);

22. }

23. }

24.

25. } // END of checkValues function

26.

[Solved] EnableVirtualScrolling strange behaviour

Hi,

I've found that Virtual Scrolling of a RadComboBox with EnableLoadOnDemand set to true doesn't work properly.
First situation: I have a RadGrid with a GridDropDownColumn. In the ItemDataBound event handler I look for the ComboBox and convert it to ComboBox with LoadOnDemand enabled:

    
            cmbUsers.EnableLoadOnDemand = true; 
        
            cmbUsers.ShowMoreResultsBox = true; 
        
            cmbUsers.AppendDataBoundItems = true; 
        
            cmbUsers.MarkFirstMatch = true; 
        
            cmbUsers.ItemRequestTimeout = 1000; 
        
            cmbUsers.EnableVirtualScrolling = true; 
        
            cmbUsers.WebServiceSettings.Method = "GetComboUsers"; 
        
            cmbUsers.WebServiceSettings.Path = "Edit1.aspx";

In this case VirtualScrolling works perfectly.

Second situation: I have a form with a RadComboBox on it:

    
            <telerik:RadComboBox runat="server" ID="ddlAttendant" Width="120px" Skin="Default" TabIndex="2" EnableLoadOnDemand="true" 
        
                      AppendDataBoundItems="True" DropDownWidth="130px" ShowMoreResultsBox="True" EnableVirtualScrolling="true" 
        
                      EmptyMessage="Select the attendant" MarkFirstMatch="True" AllowCustomText="True" ShowDropDownOnTextboxClick="False"> 
        
                  <CollapseAnimation Duration="200" Type="OutQuint" /> 
        
                   <WebServiceSettings Method="GetComboUsers" Path="Edit1.aspx" />                                           
        
                </telerik:RadComboBox>

So, I use same method to retrieve the data for my ComboBox, but in this case VirtualScrolling doesn't work at all.

I've tried different approaches (like assign properties' values in Page_Init or even create RadComboBox during Init) without any success.
Could you tell me why does it happen and how can I resolve this problem?

Get X-Axis value from Shared Template section of HTML Chart

Hello,

I'm attempting to get the x-axis value from the Shared Template section of a HTML chart so that I can pass that value to a JS function for creating the tooltip display. Is there any way of getting this value? You can see the HTML markup below.

<telerik:RadHtmlChart ID="lcPayrollBiWeekly" runat="server" CssClass="FieldLabel" EnableViewState="false">

<ClientEvents OnSeriesHover="seriesHover" />

<ChartTitle Text="Bi-Weekly Payroll Comparison" >

<Appearance BackgroundColor="White" Position="Top" />

</ChartTitle>

<Legend>

<Appearance BackgroundColor="White" Position="Bottom" />

</Legend>

<PlotArea>

<CommonTooltipsAppearance Shared="true">

<SharedTemplate>

# for (var i = 0; i < points.length; i++) { #

<div>#= formatLabel(points[i].value, points[i].value.x, points[i].series.name) #</div>

# } #

</SharedTemplate>

</CommonTooltipsAppearance>

<Appearance FillStyle-BackgroundColor="White"/>

<YAxis>

<LabelsAppearance DataFormatString="{0:C}" RotationAngle="0" />

<TitleAppearance Text ="Amount" />

<MinorGridLines Visible="false" />

</YAxis>

<XAxis>

<LabelsAppearance RotationAngle="0" />

<TitleAppearance Text="Payroll Period" />

<MinorGridLines Visible="false" />

</XAxis>

</PlotArea>

</telerik:RadHtmlChart>

Thanks,

Grid not correct displayed when Wrap = false

Hi,

I open a RadWindow with a grid inside. The problem is that the right border does not appear correctly (See attached image).

<telerik:RadGrid ID="grdStList" runat="server" AutoGenerateColumns="False" Skin="Bootstrap">

<MasterTableView NoMasterRecordsText="" DataKeyNames="VA_ARTIKEL" >

<Columns>

<telerik:GridBoundColumn DataField="ANZAHL" UniqueName="ANZAHL">

<HeaderStyle HorizontalAlign="Right" />

<ItemStyle VerticalAlign="Top" HorizontalAlign="Right" />

</telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="VA_ARTIKEL" UniqueName="VA_ARTIKEL">

<ItemStyle VerticalAlign="Top" />

</telerik:GridBoundColumn>

<telerik:GridTemplateColumn UniqueName="BEZEICHNUNG">

<ItemStyle VerticalAlign="Top" Wrap="false"/>

<ItemTemplate>

<span

><%# Eval("BEZEICHNUNG").ToString & " " & Eval("BEZEICHNUNG_ZUSATZ1").ToString & " " & Eval("BEZEICHNUNG_ZUSATZ2").ToString%></

span>

</ItemTemplate>

</telerik:GridTemplateColumn>

</Columns>

</MasterTableView>

</telerik:RadGrid>

The last column has the attribute "Wrap='false'". If I remove this attribute, the grid is displayed correctly but then the width is not correct.

How can i avoid the text to wrap and have a grid that displays correctly ?

Thank you!
