assign value to RadComboBox from database

I am using a form to insert data as well as to edit the data. Insertion of data is fine using telerik controls. But when I try to edit the data,
retrieving values from the database, I am facing problem, with RadComboBox.

My form sample is ::

<table>

<tr>

<td>Date of Birth : </td>

<td>

<telerik:RadDatePicker ID="dtp_DOB" runat="server"></telerik:RadDatePicker>

</td>

</tr>

<tr>

<td>Province : </td>

<td>

<telerik:RadComboBox ID="rcb_province" runat="server" Sort="Ascending" AutoPostBack="true" EmptyMessage="---SELECT---"></telerik:RadComboBox>

</td>

</tr>

</table>

my code behind logic ::

DataTable dt = GetPersonalDetails(p_id);

if (dt != null && dt.Rows.Count > 0)

{

DataRow dr = dt.Rows[0];

string province_ = dr["province"].ToString();

if (rcb_province.FindItemByValue(province_) != null)

{

rcb_province.FindItemByValue(dr["province"].ToString()).Selected = true;

}

Here I can get value in province_ from database but also if block is not executed.

I also tried ::

if (rcb_province.FindItemByValue(dr["province"].ToString()) != null)

{

rcb_province.FindItemByValue(dr["province"].ToString()).Selected = true;

}

it is also not working.

So how to set value from database to RadComboBox.

When I do,

rcb_province.Text = dr["province"].ToString();

the value is shown in the rcb_province but there is no other items in the combo box.

Please tell how to solve this problem.

Thanks!!!

TreeView Expand Client-Side

I have a treeview with an expand mode of ServerSideCallBack. I would like to be able to select a node by value and expanding the path via client-side. I'm was trying to get all of the parent nodes and call the expand() method down to the node, but after the first expand it told me "could not call expand of null." Could you help me with this problem?

var count = 0;
$.each(value.list, function (otherkey, othervalue) {
count = count + 1;
var tree = $find("pagesLeftNav_treeView");
var node = tree.findNodeByValue(othervalue.pageid);
if (count != value.list.length) {
node.expand();
}
})

ClientIdMode support for ASP.NET 4.0

A new feature implemented in ASP.NET 4.0 is the possibility to control the way that controls’ ClientID is generated. At present, RadControls for ASP.NET AJAX expect the ClientID’s of their child controls to be generated by the default method (AutoID). Because of that, if ClientIDMode is set to different method of generation you can experience various problems with RadControls, for example not working dialogs for RadEditor.

Here are some of the errors that you could experience when the ClientIDMode is set to Static:

All RadControls: Invalid JSON primitive:..
RadEditor's dialogs : Error: 'null' is null or not an object
RadEditor's dialogs : Sys.ArgumentNullException: Dialog Parameters for the FindAndReplace dialog do not exist Parameter name: dialogueName.
RadFileExplorer: might not display the files in the folder
RadGrid : calling get_masterTableView() returns null
"Microsoft JScript runtime error: 'get_postBackElement().id' is null or not an object"

This problem is already added to our TODO list and it should be fixed for RadControls for ASP.NET AJAX Q2 2010. For the time being, we recommend to use ClientIDMode="AutoID" or if you have to use different method you should set the ClientIDMode property’s value explicitly to AutoID to the specific RadControl.

Additional information regarding this new .NET4.0 feature is available in the following article:
ASP.NET 4.0 ClientID Overview

Please note that Microsoft does not recommend setting ClientIDMode="Static" on pages which do contain dynamic controls.

Best regards,
The Telerik team

Ajax with RadTabStrip, RadMultiPage and UserControls

Hi,

I'm trying to do an ajax update panel in a radtabstrip, radmultipage and user controls, but i can't seem to make it work.

I think it should be easy, but i have to miss something.

My structure :

Default.aspx

<telerik:RadAjaxManager ID="radManager" runat="server" />

<telerik:RadTabStrip ID="rtsSheet" runat="server" MultiPageID="radMultiPage" CausesValidation="false">

<Tabs>

<telerik:RadTab PageViewID="rpvTradeName" ToolTip="<%$ Resources: General, TradeNameTitle %>">

<TabTemplate>

<asp:Literal ID="ltrlTradeName" runat="server" Text="<%$ Resources: General, TradeName %>" />

</TabTemplate>

</telerik:RadTab>

<telerik:RadTab PageViewID="rpvViewAll" ToolTip="<%$ Resources: General, ViewAll %>">

<TabTemplate>

<asp:Literal ID="ltrlViewAll" runat="server" Text="<%$ Resources: General, ViewAll %>" />

</TabTemplate>

</telerik:RadTab>

</Tabs>

</telerik:RadTabStrip>

<telerik:RadMultiPage Width="900" ID="radMultiPage" runat="server" SelectedIndex="0">

<telerik:RadPageView ID="rpvTradeName" runat="server">

<MyUserControl:TradeName ID="ucTradeName" runat="server" />

</telerik:RadPageView>

<telerik:RadPageView ID="rpvViewAll" runat="server">

<MyUserControl:ViewAll ID="ucViewAll" runat="server" />

</telerik:RadPageView>

</telerik:RadMultiPage>

TradeName.ascx

<telerik:RadAjaxManagerProxy ID="radManager" runat="server">

<AjaxSettings>

<telerik:AjaxSetting AjaxControlID="rgTradeName">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="rgTradeName"

/>

                <telerik:AjaxUpdatedControl ControlID="rgvaTradeName" />

</UpdatedControls>

</telerik:AjaxSetting>

</AjaxSettings>

</telerik:RadAjaxManagerProxy>

<telerik:RadGrid runat="server" AllowSorting="true"

ID="rgTradeName" AutoGenerateColumns="false"

OnNeedDataSource="SheetNeedDataSource"

OnItemCommand="SheetItemCommand"

OnDeleteCommand="SheetDeleteCommand" AllowPaging="true" PageSize="10"

/>

ViewAll.ascx

<telerik:RadGrid ID="rgvaTradeName" runat="server" />

Can you tell me why my rgvaTradeName are not updated when the rgTradeName are updated ? Maybe i'm not doing it correctly ?

Thanks in advance

[Solved] Opening RadWindow Causes Page To Scroll To Top

Hey there,

We are having a problem that, given a typical search, seems rather common with RadWindows. When opening a window towards the bottom of a page that scrolls, it forces the browser back up to the top. Common causes tend to be the use of anchor tags or setting focus within the RadWindow, but these do not pertain to our situation.

We have implemented a temporary solution of capturing the scroll position and returning the page to that position, but the flicker / flash that occurs is undesirable.

After some additional testing we found that ShowContentDuringLoad seems to have something to do with it. We have this set to false to allow for our forms to load before rendering to the screen. When set to true, the browser stays put and keeps the scroll position as desired.

Has anyone else run into this problem or have any possible solutions? We'd like to keep the ShowContentDuringLoad set to false. Thanks.

Setting borders (left,right,top,bottom) on Export to excel (HTML)

I'm exporting a grid to Excel (HTML format) and i Need to have more control over the borders.

For example If I have columns "A","B", and "C" and I do not want to see the B's right border, which I guess you could also assume was C's left border.

How can I, upon exporting to excel from the rad grid, set this properly.

I've created the desired look in EXCL and attached a screen shot.

Thanks,

Grid and Form integration

I'm trying to write a grid and form where the form will display the data for the line selected on the grid.

Grid and DS

<telerik:RadGrid ID="GridPeople" runat="server" AllowFilteringByColumn="True" AllowPaging="True" AllowSorting="True" AutoGenerateColumns="False" DataSourceID="SQLDSPeople" GroupPanelPosition="Top">

<ClientSettings EnablePostBackOnRowClick="true">

<Selecting AllowRowSelect="True" />

</ClientSettings>

<MasterTableView DataSourceID="SQLDSPeople">

<Columns>

<telerik:GridBoundColumn DataField="person_ref" visible="false" UniqueName="person_ref" />

<telerik:GridBoundColumn DataField="forename1" FilterControlAltText="Filter" HeaderText="Forename" UniqueName="forename" />

<telerik:GridBoundColumn DataField="surname" FilterControlAltText="Filter" HeaderText="Surname" UniqueName="surname" />

</Columns>

</MasterTableView>

</telerik:RadGrid>

<asp:SqlDataSource ID="SQLDSPeople"

runat="server"

ProviderName="System.Data.SqlClient"

SelectCommand="SELECT [person_ref], [forename1 ], [surname] FROM [PERSON] " />

With just this, everything works find, I can select different rows and the row highlights and the code behind event gets called.

Here's the dataform and its DS.

<telerik:RadDataForm ID="FormPerson" runat="server" DataKeyNames="person_ref" DataSourceID="SQLDSPerson">

<LayoutTemplate>

<div id="itemPlaceholder" runat="server"></div>

</LayoutTemplate>

<ItemTemplate>

<fieldset>

<div>

<asp:Label runat="server" ID="FirstNameLabel2" Text="First Name:"></asp:Label>

<telerik:RadTextBox runat="server" ID="FirstNameTextBox2" Text='<%# Bind("forename1")%>' MaxLength="20" />

</div>

<div>

<asp:Label runat="server" ID="LastNameLabel2" Text="Last Name:"></asp:Label>

<telerik:RadTextBox runat="server" ID="LastNameTextBox2" Text='<%# Bind("surname")%>' MaxLength="20" />

</div>

<div>

<telerik:RadButton ID="ButtonUpdate" Text="Update" runat="server" CommandName="Update" />

</div>

</fieldset>

</ItemTemplate>

</telerik:RadDataForm>

<asp:SqlDataSource ID="SQLDSPerson"

runat="server"

ProviderName="System.Data.SqlClient"

SelectCommand="SELECT [person_ref], [forename1], [surname] FROM [PERSON] WHERE ([person_ref] = @person_ref)"

UpdateCommand="UPDATE [PERSON] SET [forename1] = @forename1, [surname] = @surname WHERE [person_ref] = @person_ref">

<SelectParameters>

<asp:ControlParameter ControlID="GridPeople" Name="person_ref" PropertyName="SelectedValue" Type="String" />

</SelectParameters>

<UpdateParameters>

<asp:Parameter Name="forename1" Type="String" />

<asp:Parameter Name="surname" Type="String" />

<asp:Parameter Name="person_ref" Type="String" />

</UpdateParameters>

</asp:SqlDataSource>

As soon as I add this, the grid select row stops working and no events are fired. Also, the grid doesn't appear at all.

Here's the code behind bits.

Private Sub Page_Init1(sender As Object, e As EventArgs) Handles Me.Init

SQLDSPeople.ConnectionString = MyConnStr

SQLDSPerson.ConnectionString = MyConnStr

End Sub

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

If Not IsPostBack Then

GridPeople.SelectedIndexes.Add(0)

End If

End Sub

Private Sub GridPeople_SelectedIndexChanged(sender As Object, e As EventArgs) Handles GridPeople.SelectedIndexChanged

FormPerson.Rebind()

End Sub

Private Sub FormPerson_ItemUpdated(sender As Object, e As Telerik.Web.UI.RadDataFormUpdatedEventArgs) Handles FormPerson.ItemUpdated

GridPeople.Rebind()

End Sub

Am I doing something wrong in the RadDataForm ?
