Hey,

Dynamically adding GridEditCommandColumns to my Grid in attempt to be able to edit chosen lines in a grid. The code to add them is below.

If ViewState("MasterEdit") Is Nothing Or Not ViewState("MasterEdit") = True Then

Dim editCol As GridEditCommandColumn

editCol = New GridEditCommandColumn

editCol.UniqueName = "MasterEditColumn"

editCol.HeaderText = ""

editCol.HeaderStyle.Width = 20

editCol.ButtonType = GridButtonColumnType.ImageButton

editCol.EditImageUrl = "~\img\edit.gif"

editCol.EditFormColumnIndex = 0

rgdTable.MasterTableView.Columns.Add(editCol)

ViewState.Add("MasterEdit", True)

End If

I do the same thing for the DetailTables. The problem I get is on the DetailTables the column just disappears entirely and on the MasterTable I get the following error:

Microsoft JScript runtime error: Sys.WebForms.PageRequestManagerServerErrorException: An error has occurred because a control with id 'ctl00$CPH1$ValueAddInfo$rgdTable$ctl00$ctl04$EditButton' could not be located or a different control is assigned to the same ID after postback. If the ID is not assigned, explicitly set the ID property of controls that raise postback events to avoid this error.

There doesn't seem to be any way to set the ID of the controls, so I can't take the advice that the error message suggests.

Grid paging stops working after publishing

I have created a web page using a Telerik Grid bound to a SqlDataSource to allow users to page through some data. Everything works correctly on my local machine, but when I publish it to the production server, it shows the first page of data but nothing else. Clicking on the navigation links only brings back the first page as does attempting to filter or sort the data. What could be causing this?

Grid Code:

<form id="form1" runat="server">

<telerik:RadScriptManager ID="RadScriptManager1" runat="server">

<Scripts>

<asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.Core.js"></asp:ScriptReference>

Grouping by month, showing month name

Hi, i have a chart which normally has a x axis with a date value.
Under certain circumstances, I'd like to group the results and show the monthly accumulated values, and show the month name

In the data I have both a date field and a month field, and I can easily group by the month field, but I can't seem to format it so that it show the month name rather than the month value.

Can you please point me in the right direction?

This is what I have so far:

Private Sub chart1_ItemDataBinding(ByVal sender As Object, ByVal e As EventArgs) Handles Chart1.ItemDataBinding

Chart1.PlotArea.XAxis.Appearance.LabelAppearance.RotationAngle = -90

If Me.ReportParameters("Time").Value.ToString.Trim = "Daily" Then

Chart1.PlotArea.XAxis.DataLabelsColumn = "userlogdate"

ElseIf Me.ReportParameters("Time").Value.ToString.Trim = "Yearly" Then

Chart1.PlotArea.XAxis.DataLabelsColumn = "year"

Chart1.DataGroupColumn = "year"

ElseIf Me.ReportParameters("Time").Value.ToString.Trim = "Monthly" Then

Chart1.DataGroupColumn = "month"

Chart1.PlotArea.XAxis.DataLabelsColumn = "month"

Chart1.PlotArea.XAxis.Appearance.ValueFormat = Charting.Styles.ChartValueFormat.ShortDate

Chart1.PlotArea.XAxis.Appearance.CustomFormat = ???

End If

End Sub

Thanks for you help

RadListBox in RadMultiPage

Hi,

I am using a Tabstrip with a multipage, navigating between pageviews by clicking the tabs.
On tab2 I placed a usercontrol containing a Radlistbox. This is rendered fine when I open the webpage with tab2 selected, it shows the 8 items inside.

But when I open the webpage with another tab selected, and then switch to tab2, the Radlistbox shows only 2 items.
This only happens in IE9, other version and browsers work fine. I use Telerik version 2011.2.712.35.

Has anyone seen this before and knows how to solve it?

Use of web.config settings "Telerik.Web.SkinsAssembly" and custom skin

Hello,

Telerik ASP.NET Ajax: 2011.3.1115.40
Language. VB.NET

We try to know how to use the web.config settings "Telerik.Web.SkinsAssembly" with a custom skin created by Telerik Style Builder.

For this, we did the following steps:
1. We created a custom skin by Telerik Style Builder named "MySkin" with all controls skinned.
2. We transformed the skin "MySkin" into an assembly "MySkinAssembly" with namespace "MySkinNamespace" by the tool of Bryan Boudreau, Telerik-webresourcebuilder:
3. We add in <appSettings> the lines:

<add key="Telerik.Web.SkinsAssembly" value="MySkinAssembly" />

<add key="Telerik.Skin" value="MySkin" />

<add key="Telerik.EnableEmbeddedSkins" value="false" />

4. In a web page, we added a <telerik:RadButton id runat ... /> but without the tag Skin, because Telerik adds it with "MySkin" taken from "Telerik.Skin" setting.

The result was that the RadButton was not skinned.

But if we add "RadStylesheetManager" with an entry for the RadButton in the page, like:

<RadStylesheetManager ...>

StyleSheets

<StyleSheetReference Name="MySkinAssembly.MySkinNamespace.Button.MySkin.css" Assembly="MySkinAssembly"
