In a GridImageColumn there is a DataAlternateTextField atribute informed with a DataItem. There are some urls that doesn't pont to any vàlid file, but the Alternate text is not shown; The alternate text exists but the grid displays an imatge placeholder.

The code is:

<telerik:GridImageColumn HeaderText="Sintrom[I]" DataImageUrlFields="ImagenSintrom" DataImageUrlFormatString="{0}"
UniqueName="Sintrom" DataAlternateTextField="TooTipSintrom">
</telerik:GridImageColumn>

403 on chartimage

Hi,

We use telerik radchart for charting in our app, we've been using it for some time and recently upgraded to 2013.2.717.40 in our app (which was the most recent version our expired subscription had).

Since then, we get a 403 error when using a chart image:

ASPX:

...

<%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Charting" TagPrefix="telerik" %>

<%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>

...

<telerik:RadChart ID="RadChart" IntelligentLabelsEnabled="True" runat="server" CssClass="RadChart" DefaultType="Spline" />

...

The web.config has:
<httpHandlers>
<add path="ChartImage.axd" type="Telerik.Web.UI.ChartHttpHandler" verb="*" validate="false" />
</httpHandlers>

and
<handlers>
<remove name="ChartImage_axd" />
<add name="ChartImage_axd" path="ChartImage.axd" type="Telerik.Web.UI.ChartHttpHandler" verb="*" preCondition="integratedMode" />
</handlers>

And I get a 403 permission denied on the url for the ChartImage.axd

The image is correctly created and cached in the appropriate temporary folder we've configured for use.

In processmonitor, as soon as that file is correctly written, the 403 failed request trace log file is created (we've enabled failed request tracing)

That file contains:
ModuleName IsapiModule
Notification 128
HttpStatus 403
HttpReason Forbidden
HttpSubStatus 0
ErrorCode 0
ConfigExceptionInfo
Notification EXECUTE_REQUEST_HANDLER
ErrorCode The operation completed successfully. (0x0)

I'm now at a loss.

I can't see anything being denied permissions and it looks like the web.config is set right for charting.

Any ideas?

Problems using RadGrid inside RadSplitter

Hi,

in my project, I changed my implementation from scrolling a grid inside a radpane to a non-scrolling radpane with a scrolling grid with static headers. Unfortunately, this leads to some problems. I've attached an aspx page for reproduction purposes.

Problems are:
1) using sender.getInnerHeight() where sender is the pane just resized, returns an incorrect value. This leads to the problem, that vertical scrollbar bottom end vanishes below the browser window border. This also leads to the problem that horizontal scrollbars vanish below the bottom browser window border (only IE7, because FF3 doesn't even show horizontal scrollbars).
2) I can't get horizontal scrollbars to become visible in FF3 - although in IE7 they exist.
3) right above the horizontal scrollbar, there is a ugly grey rectangle visible inFF3 that matches the height of the grid header. Of course, I'd like to get rid of this rectangle.
4) the grid tries to horizontally 'squash' itself in FF3 - I can't find any reason therefore. The grid in my project contains more rows than a 1280x1024 screen is able to display - so I'd like to have horizontal scrolling enabled without that squashing effect.

Here's the sample aspx page:

                    DataTable dt = new DataTable("data"); 
        
                    int colCount = 20; 
        
                    for (int i = 0; i < colCount; i++) 
        
                    { 
        
                        dt.Columns.Add("col" + i, typeof(string)); 
        
                    } 
        
                    return dt; 
        
                } 
        
            }

Would be great if somebody could point out my mistake.

Best regards

Rating values are changed after postback in RadGrid

Hi,

Both GridRatingColumn or RadRating control in a GridTemplateColumn values are changed after postback. I have attached screen shots for before-after postback. As you will see, values are not changed but ratings are. Here is my code:

<telerik:GridTemplateColumn>

<ItemTemplate>

<%# Convert.ToDouble(Eval("Yuzde")) %>

</ItemTemplate>

</telerik:GridTemplateColumn>

<telerik:GridRatingColumn DataField="Yuzde">

</telerik:GridRatingColumn>

I have put a button to trigger postback event outside of the grid. RadGrid uses NeedDataSource event to populate data. If I call RadGrid1.Rebind() method in Button1_Click event, everything works fine. What am I missing? Or is this a bug?

Thanks in advance.

Griddatetime column filtering

Hi ,

I am facing a weird problem.
When I am filtering a datetime column, I am getting the correct data that should be coming. But when the control goes to Page-PreRender event , the data is lost.
And finally I donot get any data in the radgrid.
Btw I am just changing the format of the date to match the format in the database. And that seems fine since I get correct data in the datatable that is the source of the radgrid.
The problem is only with datetimecolumn(Not with any other columntype)

Thanks in advance.

RadRibbonBar collapsing

Hello guys ... and girl,

I need a hand in resolving an issue with RadRibbonBar. As I understand, I can get it to minimize / collapse by setting its EnableMinimizing to True. That's all fine but there's a small problem to it. It can collapse, but the height would remain there, serving as unnecessary whitespace. Is there a way to adjust the height on minimize? I know that can be done with a bit of javascript and css, but would love to skip the css part, if possible that's because css varies from Skins, if I'm not mistaken.

Thank

RAD HTML5 chart: Axis item labels position issue in-case of negative values

Hi All,

I have integrated the bar-chart with my application and checked graph with different scenarios. I found one issue with rendering the negative values. The X axis labels gets plotted on the grid lines of graph. Please check the attached image("Barchart_NegativeValues.jpg"). This is looking vary ugly. I have old RAD Chart implementation in my project, I have attached sample image of old graph. In old RAD chart this case was handled.

Can anyone tell me know how to show the labels outside the graph in case of negative value(Please see attached image "old HTML Chart.jpg")

Thanks,

Rendering Problem - VS Designer

Whenever I add a Telerik control to any aspx or master page I seem to come across a rending problem.
As an example,a RadMenu is placed on a master page which only partially shows up (see attachments).
When running in browser, all appears fine and as it should.
VS2013 Professional designer is not showing anything Telerik correctly.
I've tried this on a laptop and main PC, both the same.

Any assistance appreciated.

Thanks

Tools not working

Hi,

Some of the tools on the RadEditor that I have added does not work. For example, the bold doesn't bold and the indent doesn't indent nor does the outdent.

Here's my code:

    <telerik:radeditor runat="server" ContentFilters="RemoveScripts" ID="RadEditor1" EditModes="Design"
                            OnClientLoad="OnClientLoad" Width="800px" Height="200px">
                            <Tools>
                                <telerik:EditorToolGroup Tag="Top">
                                    <telerik:EditorTool Name="AjaxSpellCheck" Enabled="true" />
                                    <telerik:EditorTool Name="Cut" />
                                    <telerik:EditorTool Name="Copy" />
                                    <telerik:EditorTool Name="Paste" />
                                    <telerik:EditorTool Name="Undo" />
                                    <telerik:EditorTool Name="Redo" />
                                    <telerik:EditorTool Name="FontName" popupwidth="150px" popupheight="150px" width="150px" />
                                    <telerik:EditorTool Name="FontSize" popupwidth="35px" popupheight="35px" width="35px" />
                                    <telerik:EditorTool Name="ForeColor" />
                                    <telerik:EditorTool Name="Bold" />
                                    <telerik:EditorTool Name="Italic" />
                                    <telerik:EditorTool Name="Underline" />
                                    <telerik:EditorTool Name="InsertUnorderedList" />
                                    <telerik:EditorTool Name="InsertOrderedList" />
                                    <telerik:EditorTool Name="Indent" />
                                    <telerik:EditorTool Name="Outdent" />
                                    <telerik:EditorTool Name="JustifyLeft" />
                                    <telerik:EditorTool Name="JustifyCenter" />
                                    <telerik:EditorTool Name="JustifyRight" />
                                    <telerik:EditorTool Name="JustifyFull" />
                                </telerik:EditorToolGroup>
                            </Tools>
                            <Content></Content>
                        </telerik:radeditor>

Also the Font tool would add an extra empty tool row in IE, but does not in Firefox or Chrome.
