[Solved] ASP.Net framework for version of the ASP.Net Ajax controls

Is there any supporting documentation showing the minimum ASP.NET framework requirements for different versions of the UI for ASP.Net Ajax controls?

I would like to use the controls going forward but have a number of legacy products that I would also like to support.

Thanks

Checked RadComboBox loosing checked state on postback

I have a Radcombobox defined as...

<telerik:RadComboBox ID="RadComboBrandCodes2" runat="server" CheckBoxes="true" ViewStateMode="Enabled" EnableViewState="true"
DataSourceID="sdsBrandCodes" DataTextField="Description" DataValueField = "Description"
Height="150px"></telerik:RadComboBox>

this combo is inside a filter template in a radgrid. When a Ajax postback happens, the items in the combo box loose their checked status. If I make a copy of the exact same markup and put it outside the grid but still within the div that gets updated via the ajax call, the checked status is maintained through the postback.

How can I get the checked state to be the same after the postback as it was before for the combo box in the filter template?

Thx,
Jeff

Configuring the PivotGrid to combine certain columns, and leave others as is

Hi Telerik,

I'm trying to achive something like in the PivotGrid_ExcelBase image. There you can see the years (2012, 2013) columns with both personen and bedrag columns underneath.

Currently I tried to achieve that with the following code:

01.<Fields>

02. <telerik:PivotGridRowField DataField="SoortIndicatie" UniqueName="SoortIndicatieColumn" Caption="Soort Indicatie" >

03. </telerik:PivotGridRowField>

04. <telerik:PivotGridRowField DataField="SoortVerzilverd" UniqueName="SoortVerzilverdColumn" Caption="Soort Verzilverd">

05. </telerik:PivotGridRowField>

06.

07. <telerik:PivotGridColumnField DataField="Jaar" UniqueName="JaarColumn" Caption="Jaar">

08. </telerik:PivotGridColumnField>

09. <telerik:PivotGridColumnField DataField="Personen" UniqueName="PersonenColumn" Caption="Personen">

10. </telerik:PivotGridColumnField>

11. <telerik:PivotGridColumnField DataField="Bedrag" UniqueName="BedragColumn" Caption="Bedrag">

12. </telerik:PivotGridColumnField>

13.</Fields>

This shows me a grid as depicted in the PivotGrid_Rendered image. The person and budget columns are also grouped, that's not what I want.
How can I configure this?

Can you tell me how to do so?

Best regards,
Francois

[Solved] Audio Captcha Language

We currently have a requirement to support an audio captcha in a language other than English (i.e. Spanish). By this, I mean the letters must be pronounced as they are in that language's alphabet. Can Telerik's captcha handle this use-case?

Radgrid Virtual Paging with Grouping

Hello ALL,

              I have a rad grid on my web page, i had applied virtual paging on rad grid as well as grouping on column.

             Rad grid page size is 30, suppose i have 250 records on rad grid so no of available pages would be 9.

              Now i had apply grouping on specific column which have following records on the basis of column value.

             There are three separation after applying grouping on column.

             Type : ABC : 242 records

              Type : DEF : 4 records

               Type : XYZ : 4 records

              Initially i can see the grouping on column but after scrolling i can view only the Type : ABC : 242 records.

              Main concern behind that the after scroll the page virtual paging get fired and i am not able to view rest of the available groups.

              Is there any solution to resolve this issue or any property/setting is to be there that i need to set.

Grid with Grouping and Paging only shows first page

This was working in previous versions of the RadControls for ASP.NET AJAX, but now with version 2012.3.1016.35 it does not. I have a grid with both grouping and paging enabled, and only the first page appears. If I remove the <telerik:GridGroupByExpression> tag from the grid then the other pages are accessible.

Am I doing something wrong or is this a bug in the otherwise excellent Telerik controls?

Thanks -
Brad Harris

Here is my markup:

<html>

<head>

<title>Grid Group & Page Test</title>

</head>

<body>

<form id="form1" runat="server">

<asp:ScriptManager ID="ScriptManager1" runat="server" />

<telerik:RadGrid

ID="RgDamageCases"

runat="server"

AllowAutomaticDeletes="false"

AllowAutomaticInserts="false"

AllowAutomaticUpdates="false"

AllowFilteringByColumn="true"

AllowMultiRowEdit="false"

AllowPaging="true"

AllowSorting="false"

AutoGenerateColumns="false"

GridLines="Horizontal"

PageSize="5"

OnNeedDataSource="RgDamageCases_NeedDataSource"

>

<MasterTableView DataKeyNames="Id" CommandItemDisplay="None">

<GroupByExpressions>

<telerik:GridGroupByExpression>

<SelectFields>

<telerik:GridGroupByField FieldAlias="State" FieldName="State" HeaderValueSeparator=": " />

</SelectFields>

<GroupByFields>

<telerik:GridGroupByField FieldName="State" SortOrder="Ascending" />

</GroupByFields>

</telerik:GridGroupByExpression>

</GroupByExpressions>

<Columns>

<telerik:GridBoundColumn UniqueName="State" DataField="State" HeaderText="State" AllowFiltering="true" AllowSorting="true" DataType="System.String" Visible="true" />

<telerik:GridBoundColumn UniqueName="Name" DataField="Name" HeaderText="Name" AllowFiltering="false" AllowSorting="true" DataType="System.String" Visible="true" />

</Columns>

<PagerStyle AlwaysVisible="true" Position="TopAndBottom" Mode="NextPrevAndNumeric" Visible="true" />

</MasterTableView>

<GroupingSettings CaseSensitive="false" ShowUnGroupButton="true" />

</telerik:RadGrid>

</form>

</body>

GridTemplateColumn causing "Object reference not set to an instance of an object"

Hello,

I've been searching for a solution to my problem, but it appears that my issue is unique.

I have had a working web site using RadGrid grid controls for several years until yesterday. Orginally, this was developed in a 2008 version of Telerik Radcontrols, but I have recently updated it to Version=2013.3.1015.35 to run on a soon-to-be sunset-ed web server. This upgrade occurred in October or so and things have been fine until a few days ago.

I had to make a change some C# logic that had been discovered to be wrong. Once the code was tested and approved, the changes were pushed to the production server. A few days later, it was discovered that there was a problem adding records to the back-end database and having the grid redraw itself. In fact, the error seems to be coming from the client since it is bypassing any server side error handling that I've built.

The funny twist on this is that there is nothing really happening to the grid. The users are selecting data from ASP controls that will then be posted back to the database and the grid will be redrawn after the users is done selecting and typing what they need. They don't get that far. Before there can be any finalization, the ASP form throws and unhandled exception and references a GridTemplateColumn as the culprit.(See attached). All server-side code executes without a hitch, but as soon as the grid is being drawn, this error comes up.

Here is the RadGrid ASP.NET code for the GridTemplateColumn:

<telerik:GridTemplateColumn

UniqueName="tempLDTEff1"

DataType="System.DateTime"

HeaderText="LDT1 Effective Date"

Reorderable="False"

Resizable="False"

ShowSortIcon="False"

HeaderStyle-Width="80px"

DataField="LDT1EffPct"

ReadOnly="True"

>

<HeaderTemplate>
