i have a radgrid with detailtables ,
detailTable has "GridEditCommandColumn" and another "GridTemplateColumn" that contains linkbutton to remove row ,
<MasterTableView DataKeyNames="FEATURE_ID">
<Columns>
<telerik:GridBoundColumn DataField="FEATURE_ID" UniqueName="FeatureID" ></telerik:GridBoundColumn>
</Columns>
<DetailTables>
<telerik:GridTableView ShowHeader="true" CommandItemDisplay="Top"
SkinID="RadGridSkin" Width="100%" runat="server" Name="Fees"
EditMode="InPlace">
<Columns>
<telerik:GridEditCommandColumn></telerik:GridEditCommandColumn>
<telerik:GridBoundColumn DataField="FEE_TEMPLATE_ID" UniqueName="FeeID"></telerik:GridBoundColumn>
<telerik:GridTemplateColumn UniqueName="DeleteFee">
<ItemTemplate>
<asp:LinkButton ID="RemoveFee" runat="server" CommandName="RemoveFee" Text="RemoveFee" ImageUrl="../../../images/cancel.png" ToolTip="<%$Resources:Strings,remove %>" />
</ItemTemplate>
</telerik:GridTemplateColumn>
</Columns>
</telerik:GridTableView>
</DetailTables>
</MasterTableView>
in code behind in itemCommand event :
dataSource of radgrid is updated and Datable.acceptchanges() is called ;
how to rebind only the detailTable where changes have occurred ??
You didn't supply the name of your RadGrid, but the first thing I would try is:
RadGrid1.MasterTableView.DetailTables(0).Rebind(),
or, although I'm not sure whether this works for you (it compiles in VS for me), you might be able to say:
RadGrid1.MasterTableView.DetailTables("Fees").Rebind().
Obviously, replace 'RadGrid1' with the name of your RadGrid.

I have a RadGrid That is used in several ASPX applications. It works fine in other apps. However when I copy and paste it into this aspx page it does not work. I get no error messages and the OnNeedData method shows records being pulled. All I get is a white line where the RadGrid should appear. Below is the RAdGrid Setup
<telerik:RadGrid ID="RadGridSubject" runat="server"
OnInsertCommand="RadGridSubject_InsertCommand"
OnUpdateCommand="RadGridSubject_UpdateCommand"

Why would it work on other pages within the web app but not this one? When you copy and paste a RADGrid do I need to reset all of the properties?
This was an error on my part. I failed to Bind the RadGrid once I did that the control worked as designed.
In a nutshell, I have RadGrid with edit form with type of WebUserControl.
<telerik:RadAjaxPanel runat="server">
<telerik:RadGrid ...>
<Columns>
...
</Columns>
<EditFormSettings UserControlName=".../EditForm.ascx" EditFormType="WebUserControl">
</EditFormSettings>
</MasterTableView>
</telerik:RadGrid>
</telerik:RadAjaxPanel>
EditForm contains RadUpload control. The problem is: in OnUpdateCommand UploadedFiles of RadUpload all time is empty. I can't get and save uploaded file.
I'm using GridView and there is a dropdownlist in header cell for filtering.
<gm:GridView ID="routePlanGridView" runat="server" AutoGenerateColumns="False"
AllowPaging="true" PageSize="20" GridLines="Both" ShowFooter="true" CssClass="grid"
DataKeyNames="RoutePlanId" OnSorting="routePlanGridView_Sorting"
AllowSorting="true" OnPageIndexChanging="routePlanGridView_PageIndexChanging"
OnSelectedIndexChanging="routePlanGridView_SelectedIndexChanging"
OnRowDataBound="routePlanGridView_RowDataBound"
OnRowEditing="routePlanGridView_RowEditing"
OnRowUpdating="routePlanGridView_RowUpdating">
<HeaderStyle CssClass="gridHeaderFooter" />
<FooterStyle CssClass="gridHeaderFooter" />
<RowStyle CssClass="gridRow" />
<AlternatingRowStyle CssClass="gridRowAlternate" />
<Columns>
<asp:TemplateField SortExpression="SPName">
<HeaderTemplate>
SP Name<br />
<asp:DropDownList ID="spNameFilterDDL" runat="server" CssClass="gridControl" AutoPostBack="true" DataSourceID="SPNameSDS" DataTextField="SPName" OnDataBound="filterDDL_DataBound" OnSelectedIndexChanged="spNameFilterDDL_SelectedIndexChanged" />
</HeaderTemplate>
<ItemTemplate>
<asp:Label ID="spNameLabel" runat="server" Text='<%# Bind("SPName") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<...15 more...>
</Columns>
</gm:GridView>
and there are relevant event handlers for sorting and paging.
Now the problem is if I put "SP Name" text in a link button, page crashes when link clicked, otherwise no link produced to sort.
If I remove Header Template fields (all of them) and put a text with HeaderText attribute of TemplateField it works as expected. Is there a way to put them together? I need that dropdown and also sorting.
Thanks.
sorry, forgot to insert the code correctly - here:
<asp:LinkButton runat="server" Text="SP Name" CommandName="Sort" CommandArgument="SPName" ></asp:LinkButton>
You need to use a link button for your header text. So in place of "SP Name", use . It should work if you are handling sorting.
Here's my grid:
<telerik:RadGrid AutoGenerateColumns="False" ID="grdUsers" DataSourceID="LinqDataSource1" AllowSorting="True" runat="server" GridLines="None" Skin="Office2007">
<HeaderContextMenu CssClass="GridContextMenu GridContextMenu_Default"></HeaderContextMenu>
<MasterTableView TableLayout="Fixed" DataSourceID="LinqDataSource1">
<CommandItemSettings ExportToPdfText="Export to Pdf"></CommandItemSettings>
<RowIndicatorColumn FilterControlAltText="Filter RowIndicator column"></RowIndicatorColumn>
<ExpandCollapseColumn FilterControlAltText="Filter ExpandColumn column"></ExpandCollapseColumn>
<Columns>
<telerik:GridBoundColumn HeaderText="FirstName" DataField="FirstName" ReadOnly="True" SortExpression="FirstName" HeaderStyle-Width="150"></telerik:GridBoundColumn>
<telerik:GridBoundColumn HeaderText="LastName" HeaderStyle-Width="150" DataField="LastName" ReadOnly="True" SortExpression="LastName"></telerik:GridBoundColumn>
<telerik:GridBoundColumn HeaderText="Email" DataField="Email" ReadOnly="True" SortExpression="Email"></telerik:GridBoundColumn>
<telerik:GridCheckBoxColumn HeaderText="Delete?" HeaderStyle-Width="60" ReadOnly="false"></telerik:GridCheckBoxColumn>
</Columns>
<EditFormSettings>
<EditColumn FilterControlAltText="Filter EditCommandColumn column"></EditColumn>
</EditFormSettings>
</MasterTableView>
<FilterMenu EnableImageSprites="False"></FilterMenu>
</telerik:RadGrid>
As you can see, I have a GridCheckBoxColumn at the end that I would like the users to be able to select a few records and then click another button to delete them. The problem is that the check boxes are all disabled even though I set the ReadOnly property to false.
Any ideas?
You are using the GridCheckBoxColumn incorrectly. It must be bound to a datafield just like a GridBoundColumn. In your case, you need to place a CheckBox in an ItemTemplate of a GridTemplateColumn. This will achieve your desired result.
Here is a link from Telerik going through the entire process: http://www.telerik.com/help/aspnet/grid/grddeletegriditemsdependingoncheckboxstate.html
I'm new to Entity Framework and I got stuck in an issue while trying to bind a navigation property (foreign key reference) to a dropdownlist. I have Telerik RadGrid control which gets the data using a EntityDataSource control. Here is the model description:
Applications: AppId, AppName, ServerId
Servers: ServerId, ServerName
The Applicaitons.ServerId is a foreign key reference to Servers.ServerId. The RadGrid lists the applications and allows the user to insert/update/delete an application. I want to show the server names as a dropdownlist in edit mode which I'm not able to. . Here is my aspx code:
<telerik:RadGrid ID="gridApplications" runat="server" Skin="Sunset"
AllowAutomaticInserts="True" AllowAutomaticDeletes="True"
AllowPaging="True" AllowAutomaticUpdates="True"
AutoGenerateColumns="False" OnItemCreated="gridApplications_ItemCreated"
DataSourceID="applicationsEntityDataSource" Width="50%"
OnItemInserted="gridApplications_ItemInserted"
OnItemUpdated="gridApplications_ItemUpdated"
OnItemDeleted="gridApplications_ItemDeleted" GridLines="None">
<MasterTableView CommandItemDisplay="Top" AutoGenerateColumns="False" DataKeyNames="AppId" DataSourceID="applicationsEntityDataSource">
<RowIndicatorColumn>
<HeaderStyle Width="20px" />
</RowIndicatorColumn>
<ExpandCollapseColumn>
<HeaderStyle Width="20px" />
</ExpandCollapseColumn>
<Columns>
<telerik:GridEditCommandColumn ButtonType="ImageButton" UniqueName="EditCommandColumn" HeaderText="Edit" ItemStyle-Width="10%">
</telerik:GridEditCommandColumn>
<telerik:GridButtonColumn CommandName="Delete" Text="Delete" UniqueName="DeleteColumn" ConfirmText="Are you sure you want to delete this application?" ConfirmTitle="Confirm Delete" ConfirmDialogType="Classic" ItemStyle-Width="10%" HeaderText="Delete">
</telerik:GridButtonColumn>
<telerik:GridBoundColumn DataField="AppId" UniqueName="AppId" Visible="false" HeaderText="Application Id" ReadOnly="true">
</telerik:GridBoundColumn>
<telerik:GridBoundColumn DataField="AppName" UniqueName="AppName" HeaderText="Application Name" MaxLength="30" ItemStyle-Width="40%">
</telerik:GridBoundColumn>
<telerik:GridTemplateColumn DataField="ServerId" UniqueName="ServerId" HeaderText="Server Hosted" EditFormColumnIndex="1">
<EditItemTemplate>
<asp:DropDownList ID="ddlServerHosted" runat="server" DataTextField="Servers.ServerName" DataValueField="ServerId" Width="40%">
</asp:DropDownList>
</EditItemTemplate>
</telerik:GridTemplateColumn>
</Columns>
<EditFormSettings ColumnNumber="2" CaptionDataField="AppId" InsertCaption="Insert New Application" EditFormType="AutoGenerated">
<EditColumn InsertText="Insert record" EditText="Edit application id #:" EditFormColumnIndex="0" UpdateText="Application updated" UniqueName="InsertCommandColumn1" CancelText="Cancel insert" ButtonType="ImageButton"></EditColumn>
<FormTableItemStyle Wrap="false" />
<FormTableStyle GridLines="Horizontal" CellPadding="2" CellSpacing="0" Height="110px" Width="110px" />
<FormTableAlternatingItemStyle Wrap="false" />
<FormStyle Width="100%" BackColor="#EEF2EA" />
<FormTableButtonRowStyle HorizontalAlign="Right" />
</EditFormSettings>
</MasterTableView>
</telerik:RadGrid>
<asp:EntityDataSource ID="applicationsEntityDataSource" runat="server"
ConnectionString="name=AnalyticsEntities" EnableDelete="True"
EntityTypeFilter="Applications" EnableInsert="True" EnableUpdate="True" EntitySetName="Applications"
DefaultContainerName="AnalyticsEntities" Include="Servers">
</asp:EntityDataSource>
I tried another approach where I replaced the GridTemplateColumn with the following code
<telerik:RadComboBox ID="RadComboBox1" DataSourceID="serversEntityDataSource" DataTextField="ServerName" DataValueField="ServerId" AppendDataBoundItems="true" runat="server" >
<Items>
<telerik:RadComboBoxItem />
</Items>
and using a separate EntityDataSource control as follows:
<asp:EntityDataSource ID="serversEntityDataSource" runat="server"
ConnectionString="name=AnalyticsEntities" EnableDelete="True"
EntityTypeFilter="Servers" EnableInsert="True" EnableUpdate="True" EntitySetName="Servers"
DefaultContainerName="AnalyticsEntities">
</asp:EntityDataSource>
but, I get the following error.
Application cannot be inserted. Reason: Entities in 'AnalyticsEntities.Applications' participate in the 'FK_Servers_Applications' relationship. 0 related 'Servers' were found. 1 'Servers' is expected.
My question is, how do you bind the navigation property and load the values in the DropDownList/RadComboBox control?
I believe you bind your dropdownlist to that second datasource instead of the grid's datasource (as you did in the second example). Then you set the SelectedValue property on the dropdown/combobox using the <%# BIND("ServerId") %> syntax within the template.
