Hide all headers in RadGrid (when using ItemTemplate)

I am using a RadGrid to list a bunch of records using an ItemTemplate format, but want to hide the fact that it is actually a grid.

Right now, all the headers are visible, including those for columns not being included in the ItemTemplate.

I'm sure I am just missing a simple setting, but I can't find it. How do I hide the headers altogether?

Hierarchical grid loses child tables after postback

Hi,

I have problem with hierarchical grid. It loses child tables and data after postback. The problem is with my own component which wraps grid with search textbox control.

If I'm using grid without my component it works correctly:

<telerik:RadGrid ID="grd" runat="server" PageSize="40" DataSourceID="ds1" AllowPaging="true" AllowAutomaticDeletes="true" Width="650px"

OnSelectedIndexChanged="userList_ResultGrid_SelectedIndexChanged" OnItemDeleted="userList_ResultGrid_ItemDeleted">

<MasterTableView AutoGenerateColumns="false" DataKeyNames="Id" ClientDataKeyNames="Id" HierarchyLoadMode="Client">

<DetailTables>

<telerik:GridTableView DataSourceID="ds2" DataKeyNames="Id" ClientDataKeyNames="Id" Width="100%" Name="UserRoles" AutoGenerateColumns="false" AllowPaging="false" NoDetailRecordsText="No additional roles assigned with this user.">

<ParentTableRelation>

<telerik:GridRelationFields DetailKeyField="PrimaryUserId" MasterKeyField="Id" />

</ParentTableRelation>

<Columns>

<telerik:GridBoundColumn DataField="Role.Title" HeaderText="Role" />

</Columns>

</telerik:GridTableView>

</DetailTables>

<Columns>

<telerik:GridTemplateColumn HeaderText="">

<HeaderStyle Width="32px" />

<ItemTemplate>

<asp:Panel ID="Active" runat="server" Style="height: 16px; width: 16px;" CssClass='<%# (bool)Eval("Active") ? "active-user" : "disabled-user" %>' />

</ItemTemplate>

</telerik:GridTemplateColumn>

<telerik:GridBoundColumn DataField="Name" HeaderText="User Name" />

<telerik:GridBoundColumn DataField="Email" HeaderText="Login" />

<telerik:GridButtonColumn ConfirmText="Are you sure you want to delete this user?"

ConfirmDialogType="Classic" ConfirmTitle="Delete" ButtonType="ImageButton" CommandName="Delete"

</telerik:RadGrid>

<asp:EntityDataSource ID="ds1" runat="server" ContextTypeName="ImpersonatedSecurityEntities" EntitySetName="Users" Where="it.PrimaryUserId is null" />

<WhereParameters>

<asp:Parameter Name="PrimaryUserId" DbType="Guid" />

</WhereParameters>

</asp:EntityDataSource>

I'm using my component more than 1 year without problems but I never defined hierarchy. Now I added hierarchy and it does not work. Here is the code:

<bfo:GridSmartSearch ID="userList" runat="server" ShowAlphabeticPager="true" AlphabeticPagerType="Full"

GridSmartSearchType="AjaxManager">

<SearchTextBox EmptyMessage="Type here to search users..." Width="250px" />

<ResultGrid PageSize="40" AllowPaging="true" AllowAutomaticDeletes="true" Width="650px"

OnSelectedIndexChanged="userList_ResultGrid_SelectedIndexChanged" OnItemDeleted="userList_ResultGrid_ItemDeleted">

<MasterTableView AutoGenerateColumns="false" DataKeyNames="Id" ClientDataKeyNames="Id" HierarchyLoadMode="Client">

<DetailTables>

<telerik:GridTableView DataSourceID="dsA" DataKeyNames="Id" ClientDataKeyNames="Id" Width="100%" Name="UserRoles" AutoGenerateColumns="false" AllowPaging="false" NoDetailRecordsText="No additional roles assigned with this user.">

<ParentTableRelation>

<telerik:GridRelationFields DetailKeyField="PrimaryUserId" MasterKeyField="Id" />

</ParentTableRelation>

<Columns>

<telerik:GridBoundColumn DataField="Role.Title" HeaderText="Role" />

</Columns>

</telerik:GridTableView>

</DetailTables>

<Columns>

<telerik:GridTemplateColumn HeaderText="">

<HeaderStyle Width="32px" />

<ItemTemplate>

<asp:Panel ID="Active" runat="server" Style="height: 16px; width: 16px;" CssClass='<%# (bool)Eval("Active") ? "active-user" : "disabled-user" %>' />

</ItemTemplate>

</telerik:GridTemplateColumn>

<telerik:GridBoundColumn DataField="Name" HeaderText="User Name" />

<telerik:GridBoundColumn DataField="Email" HeaderText="Login" />

<telerik:GridButtonColumn ConfirmText="Are you sure you want to delete this user?"

ConfirmDialogType="Classic" ConfirmTitle="Delete" ButtonType="ImageButton" CommandName="Delete"

Text="Delete" UniqueName="DeleteColumn" ImageUrl="~/Data/Skins/First/Grid/Delete.png">

<HeaderStyle Width="32px" />

<ItemStyle HorizontalAlign="Center" />

</telerik:GridButtonColumn>

</Columns>

</MasterTableView>

<ClientSettings EnablePostBackOnRowClick="true">

<Selecting AllowRowSelect="true" />

<ClientEvents OnRowContextMenu="users_RowContextMenu" />

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

</ClientSettings>

</ResultGrid>

[Solved] Introduce Facebook-like Tooltips

Anyone who uses Facebook is aware of the red-circled "1", "2", "3" . . . etc. that appears near the top of the screen. This images look like tooltips though stay visible until various other things in the app occur.

Is this something I can emulate with the RadToolTip? If so, how?

If not, do you have any suggestions how I could do it otherwise?

ExportToPdf Roadmap

Hello,

Do you have a roadmap for the RadEditor ExportToPdf feature?
1. Does it support fonts other than TimesNewRoman?
2. Does it support loacalized fonts (polish)?
3. Is it possible to save pdf on the server instead of outputting it to the client?

Kind regards,
Bart
