I bound a datattable datasource to the RadImageGallery, therea huge images with a size > FullHD. I want to show the images with a size of maxX=800 and/or maxY=800. The aspx code looks like this

<telerik:RadImageGallery runat="server" ID="IGAL1" DisplayAreaMode="LightBox" width="800px"

OnNeedDataSource="IGAL1_NeedDataSource" DataDescriptionField="BEMERKUNG" DataImageField="DOKUMENT_BLOB" DataTitleField="NAME" LoopItems="true" ShowLoadingPanel="true" >

<ToolbarSettings ShowSlideshowButton="true" ShowItemsCounter="true" ItemsCounterFormat="Images {0} of {1}" />

<ImageAreaSettings ShowDescriptionBox="true" Height="800px" Width="800px" ResizeMode="Fit" CloseButtonText="Schließen" NextImageButtonText="Nächstes Bild" PrevImageButtonText="Vorheriges Bild" />

<ThumbnailsAreaSettings ThumbnailsSpacing="1px" ThumbnailWidth="120px" ThumbnailHeight="80px" Height="80px" ShowScrollbar="true" ShowScrollButtons="true" />

</telerik:RadImageGallery>

If I click on a thumbnail the popup always fits the whole screen and ignore the width and hight settings of the RadImagegallery.

radeditor toolbarmode does not work

Hi,

I am using Telerik RadEditor (V 2013.2.611.35) in which I have to use EditorToolbarMode.ShowOnFocus property for that control. But when I set that property then the toolbar gets hide automatically and it does not appear even after focus the control.

Can anyone have workaround for this issue?

Note: I am using dynamic radeditor control where it's created on aspx.cs page and I have added blur event for that by using $telerik.addExternalHandler(element, "blur", function (e) { restorePoint = editor.createRestorePoint(); }); method. Will that make a difference?

Error in EditMode"Batch" when changing row

Hi,

Using the RadGrid in Batch Editing mode and the EditType is set to row. I forbid edition in some columns with:

function BatchEditOpening(sender, args) {

var col = args.get_columnUniqueName();

if (isNaN(col.substring(0,1))) {

args.set_cancel(true);

}

It works, but when I want to jump in another row, I am getting the following error:"The property "style" of an undefined or zero reference can not be retrieved." (I translate the error). When I comment this code, it work.

What am I doing wrong?

Thanks!

Hover image for pager buttons

Hi!

I defined an image for a pager button with RadGrid.PagerStyle.LastPageImageUrl = "url". The downside of the approach is that there is no hover effect any more. Is it possible to define an image that is used for hover with a similar property, or do I have to use Javascript/CSS?

Kind regards

Grid - Clicking on the Header Line to Sort

Hi All,

I've a very simple page with a RadGrid, on clicking the header to sort, I get the error :-

Unable to cast object of type 'Telerik.Web.UI.RadGrid' to type 'Telerik.Web.UI.GridTableView'.

This only happened after upgrading the DLLs to 2016.2.607.40 from 2014.1.403.40
Going back to the old DLL fixes the issue.

Serverside I populate a DataTable and then use Datasource/Databind.

<telerik:RadGrid ID="dtgParameter" runat="server" CssClass="dataGridStyle" Width="99%" GridLines="Both" Height="100px" AllowSorting="True" AllowMultiRowSelection="False" AllowPaging="False" AutoGenerateColumns="False" ShowFooter="false" ShowHeader="true">

<HeaderStyle CssClass="dataGridHeader" />

<ItemStyle CssClass="dataGridItemStyleNormal" />

<AlternatingItemStyle CssClass="dataGridItemStyleAlt" />

<SortingSettings EnableSkinSortStyles="false" />

<ClientSettings EnablePostBackOnRowClick="false">

<Selecting AllowRowSelect="true" UseClientSelectColumnOnly="true" />

<Scrolling AllowScroll="True" UseStaticHeaders="True" SaveScrollPosition="True" />

</ClientSettings>

<MasterTableView Name="Parameter" DataKeyNames="ParameterId" ShowHeader="true" AutoGenerateColumns="False" HierarchyLoadMode="ServerOnDemand" width="99%">

<Columns>

<telerik:GridBoundColumn HeaderStyle-ForeColor="White" DataField="ParameterId" HeaderStyle-Font-Bold="True" SortExpression="ParameterId" HeaderStyle-Width="0%" HeaderText="" visible="false"/>

<telerik:GridBoundColumn HeaderStyle-ForeColor="White" DataField="Name" HeaderStyle-Font-Bold="True" SortExpression="Name" HeaderStyle-Width="20%" HeaderText="Name" />

<telerik:GridBoundColumn HeaderStyle-ForeColor="White" DataField="Comments" HeaderStyle-Font-Bold="True" SortExpression="Comments" HeaderStyle-Width="80%" HeaderText="Comments" />

</Columns>

</MasterTableView>

</telerik:RadGrid>

Binding issue

Hi,

I have the following client code and JSON output. When I run it up I get no errors but I get an empty combo box. I know that the JSON is being generated and sent to the client datasource.

Have I missed something obvious?

<telerik:RadClientDataSource runat="server" ID="RadClientDataSource1">

<DataSource>

<WebServiceDataSourceSettings BaseUrl="http://localhost:65247/aTest/Data.asmx/">

<Select Url="GetData" DataType="JSON" />

</WebServiceDataSourceSettings>

</DataSource>

<Schema DataName="data">

<Model>

<telerik:ClientDataSourceModelField FieldName="Id" DataType="Number" />

<telerik:ClientDataSourceModelField FieldName="Nme" DataType="String" />

<telerik:ClientDataSourceModelField FieldName="Ena" DataType="Boolean" />

</Model>

</Schema>

</telerik:RadClientDataSource>

<telerik:RadComboBox ID="RadComboBox1" runat="server" ClientDataSourceID="RadClientDataSource1" EnableLoadOnDemand="true"

DataTextField="Nme" DataValueField="Id">

</telerik:RadComboBox>

Sample JSON below - I have checked the whole file with a checker and it all seems OK...

{"data":[{"Id":97,"Nme":"sample 1","Ena":true},{"Id":182,"Nme":"sample 2","Ena":true}]}
