Trying to get a Heiarchy grid to update the nested grid

Situation,
I have a hierarchy grid where in the nested grid a link pops up a modal pop-up so the user can edit all of the contents of the object, the nested grid only shows a selected portion. upon saving all is good except the nested grid, I cannot seem to figure out how to refresh it, unless I reload the entire page which I guess would work but not preferable. would like to just refresh the nested grid but will settle for the whole grid if need be.

Aspx Code:

    
            <asp:UpdatePanel ID="upnlGrid" runat="server" UpdateMode="Conditional"> 
        
            <ContentTemplate>

Can add button image be used for other controls?

Hi

I would like to know if the add button that appears in the radgrid can be used in other parts of a web page? For instance when you edit a row in the radGrid or Add a new record, I would like to be able to have an add button next to some of the drop downs that may appear in the details section of the radGrid. I would like to use the add button of the current skin

Thanks

[Solved] Dockzone issue.....

Hi there

We are creating a site which uses the Docks and Zones from Telerik.

So far we have based our testing on an example provided to use from you guys - 162243_savedockstatedbloadingpanel.vb

Initially we were only concerned with loading dock states from the db - which works very well.

We are now trying to use the 'Add Dock' functionality but have hit a couple of problems....

1> There is a function in the Telerik example:

Public Function GetZones() As ArrayList

Dim zones As New ArrayList()

zones.Add(RadDockZone1)

zones.Add(RadDockZone2)

Return zones

End Function

Although this works in the example when we try to replicate it in our tests this does not populate the drop down list??

2> The save function.....

Protected

Sub ButtonAddDock_Click(ByVal sender As Object, ByVal e As EventArgs)

Dim dock As RadDock = CreateRadDock()

'find the target zone and add the new dock there

Dim dz As RadDockZone = DirectCast(FindControl(DropDownZone.SelectedItem.Text), RadDockZone)

dz.Controls.Add(dock)

CreateSaveStateTrigger(dock)

'Load the selected widget in the RadDock control

dock.Tag = DroptDownWidget.SelectedValue

LoadWidget(dock)

ScriptManager.RegisterStartupScript(Me, Me.[GetType](), "MoveDock", String.Format("function _moveDock() {{" & vbCr & vbLf & vbTab & vbTab & vbTab & " " & vbTab & "Sys.Application.remove_load(_moveDock);" & vbCr & vbLf & vbTab & vbTab & vbTab & vbTab & " $find('{1}').dock($find('{0}'),{2});" & vbCr & vbLf & vbTab & vbTab & vbTab & " }};" & vbCr & vbLf & vbTab & vbTab & vbTab & " Sys.Application.add_load(_moveDock);", dock.ClientID, DropDownZone.SelectedValue, dz.Docks.Count), True)

End Sub

...throws an error on this line:

Dim dz As RadDockZone = DirectCast(FindControl(DropDownZone.SelectedItem.Text), RadDockZone)

saying it cant find the RadDockZone.

Again this works fine on your example but not in our tests.

If I hard code the above line. for example: Dim dz As RadDockZone = RadDockZone1

then it finds the zone but then throws an exception when '$find('{1}').dock($find('{0}'),{2});" ' is called.

It would appear the 2 issues are related and are not due to bad or wrong coding. I think its a page lifecycle issue but cant seem to get to the bottom of it.

Can you help please as we are 90% towards achieving the required functionality.

How to setup a GridHierachy with this kind of Source

Good Day All

My datasource is a List as defined like this

public List<EAV> GetRecords(List<string> ParentRecords, List<string> ChildRecords)

{

List<EAV> Final = new List<EAV>();

for (int i = 0; i < ParentRecords.Count; i++)

{

//Put a check for child records exists and add

Final.Add(new EAV(ParentRecords[i], ChildRecords[0]));

//Start looping from 2nd J = 1 instead of 0

for (int J = 1; J < ChildRecords.Count; J++)

{

//remove ParentRecords[i]

Final.Add(new EAV("", ChildRecords[J]));

}

return Final;

}

And as you can see it brings back a list. Now this will arrange everything in hiearchial form but i need to be able to collapse and uncollase the results , but now it shows in a Grid as normal data as depicted in the image below

Thanks

[Solved] Change width of snippets dropdown

We are using the snippets dropdown to add custom values to html based letters/emails. The Names text in the dropdowns are getting long and I would like to increase the width of the dropdown to accommodate the longer names. Here is our usage.

<td valign="middle" colspan="2">
	<AesopControls:AesopRadEditor runat="server" ID="E"
		Content='<%# Bind("LetterHtml") %>' 
		SkinID="LetterEditor" Height="400px"
		ImageCatalogDefaultDirectory="Client"
		>
		<Snippets>
			<telerik:EditorSnippet Name="<span style='color:red;'>---Project---</span>" Value="" />
			<telerik:EditorSnippet Name="Project Name" Value="{ProjectName}" />
			<telerik:EditorSnippet Name="Project Date" Value="{ProjectDate}" />

SelectedIndex does not refresh control when using RadAjaxManager

This could just be my ignorance on how the RadAjaxManager/client-side action works, but I'm having a problem getting the Combo Box selected value to change in a specific scenario using the RadAjaxManager.

In this demo, I'm just trying to set the third combo to whatever index the second one is set to. This is not a desired production action, just a way to test whether the index is actually changing or not. In all cases, the third combo includes more than the number of items in the second combo.

Using this code, the third combo box refreshes correctly, but I'm having the whole page refresh each time, as a result of the AutoPostBack's:

Default4.aspx.vb

Partial Class Default4

Inherits System.Web.UI.Page

Protected Sub cboInterventionTools_SelectedIndexChanged(ByVal o As Object, ByVal e As Telerik.Web.UI.RadComboBoxSelectedIndexChangedEventArgs) Handles cboInterventionTools.SelectedIndexChanged

cboInterventionDurations.SelectedIndex = cboInterventionTools.SelectedIndex

End Sub

End Class

Default4.aspx

<%@ Page Language="VB" AutoEventWireup="false" CodeFile="Default4.aspx.vb" Inherits="Default4" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

</SelectParameters>

</asp:SqlDataSource>

<telerik:RadComboBox AutoPostBack="true" Height="300px" Width="200px" runat="server"

</telerik:RadComboBox>

<br />

<asp:ControlParameter ControlID="cboAreasOfConcern" Name="AreaOfConcernID"

PropertyName="SelectedValue" />

<asp:Parameter DefaultValue="8" Name="GradeLevelID" />

<asp:Parameter DefaultValue="1" Name="DummyParameter" />

</SelectParameters>

</asp:SqlDataSource>

<telerik:RadComboBox AutoPostBack="true" Height="300px" Width="200px" runat="server"

ID="cboInterventionTools"

DataSourceID="sqlInterventionTools" DataTextField="InterventionToolName"

DataValueField="InterventionToolID" ExpandDelay="0">

</telerik:RadComboBox>

<br />

Intervention Duration<br />

<asp:SqlDataSource ID="sqlInterventionDurations" runat="server"

ConnectionString="<%$ ConnectionStrings:RTIDesktop %>"

SelectCommand="InterventionDurations_List" SelectCommandType="StoredProcedure">

</asp:SqlDataSource>

<telerik:RadComboBox Height="300px" Width="200px" runat="server"

ID="cboInterventionDurations"

DataSourceID="sqlInterventionDurations" DataTextField="InterventionDurationName"

DataValueField="InterventionDurationID" ExpandDelay="0">

</telerik:RadComboBox>

<br />

</asp:Panel>

</div>

</form>

</body>

</html>

Everything works great, the cboInterventionTools_SelectedIndexChanged() routine runs, and the cboInterventionDurations.SelectedIndex gets changed correctly.

If I add RadAjaxManager functionality, so that the screen doesn't refresh, the routine runs, but the combo control does not refresh:

Code added to Default4.aspx:
(right after the ScriptManager)

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">

<AjaxSettings>

<telerik:AjaxSetting AjaxControlID="cboAreasOfConcern">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="cboInterventionTools" />

</UpdatedControls>

</telerik:AjaxSetting>

</AjaxSettings>

</telerik:RadAjaxManager>

The idea is that any change to "Areas of Concern" automatically refreshes the "Intervention Tool", client-side.

I need to be able to change the "Intervention Duration" to reflect a specific default duration time per tool. It needs to make a call to SQL to determine that information. If I embed that code into the cboInterventionTools_SelectedIndexChanged() routine, it all runs, and it even SETS the index correctly... but the control never changes visually on the screen.

Is there something I need to do to trigger that combo refresh, client-side, once the routine has completed?

Handling errors using Declarative Data Source?

Hi,
I need to create a number of simple pages to display grid-like data, and using a Declarative Data Source (with SqlDataSource) seems like a good idea to save time. But I cannot be sure that the data source is ready at all times. In that case I'd like to simply display an empty grid.

Any suggestions, can (login) errors easily be trapped at some point?
Thanks.

Best,
Olav

No Repeating Data

Hi -

I have a column in the database that has repeating values. I'm using that column to populate a ComboBox on my page. I don't want the repeated values to show up, but just the one time.

Example:

1940
1940
1940
1950
1950
1960
1970
1970
1970

So, I only want this to be populated in the ComboBox:
1940
1950
1960
1970

Is there a parameter or keyword that can be used on the aspx side or the c# side that can give me the outcome I need?

Here is my c#:

private void PopulateComboBox()

{

IQueryable allSystemPlantAccount = system_PlantAccount.GetAllBindings();

this.systemPlantAccountRadComboBox.DataSource = allSystemPlantAccount;

this.systemPlantAccountRadComboBox.DataValueField = "ID";

this.systemPlantAccountRadComboBox.DataTextField = "Year";

this.systemPlantAccountRadComboBox.DataBind();

this.systemPlantAccountRadComboBox.Filter = RadComboBoxFilter.Contains;

this.systemPlantAccountRadComboBox.Sort = RadComboBoxSort.Ascending;

this.systemPlantAccountRadComboBox.SortItems();

}

Here is my aspx:

<telerik:RadComboBox ID="systemPlantAccountRadComboBox" runat="server" Width="200px"

style="left: 20px; top: 125px; position: absolute; text-align: right;"></telerik:RadComboBox>

Any help would be great. Thanks!

GridAttachmentColumn

Hello everybody!

i must admit that i started using telerik components just recently. Right now i'm trying to use the GridAttachmentColumn to manage my attachments.

but i keep getting this error on insert "

Implicit conversion from data type sql_variant to varbinary(max) is not allowed. Use the CONVERT function to run this query

"
I use sqlserver 2005 .

so i ask, shouldnt the GridAttachmentColumn suffice to work with the datasource? Or do i have to use a gridTemplateColumn?

thanx!

Load XML Data into Menu via Skin

In an older version of the RadMenu (v 3.6.4.0), I was able to load my xml data into a radmenu inside of a skin.

Skin syntax:

<telerik:RadMenu

runat="server"

SkinID="EditCommandMenu"

Width="100%"

ClickToOpen="true"

CausesValidation="false"

AccessibilityEnabled="True"

AutoPostBack="false"

ContentFile="~/PresentationLayer/Manifests/Menu/Edit/Commands.xml"

ImagesBaseDir="~/PresentationLayer/Images/Menu/Default" />

I am in the process of upgrading to the latest version and this functionality seems to be removed.
Does anyone know how to inject my XML into a Menu via a Skin?

Thanks!
