Error when using aggregate on Total_goals

HI,
I have aggergate problem on one of the column Total_goal of the data source. If remove the aggergate then no exception.
What is the reason for this behaviour? Clearly Total_Goal Column is the part of data source.

<telerik:GridTemplateColumn Aggregate="Sum" DataField="Total_Goal" UniqueName="TotalGoals" ItemStyle-Width="75px" HeaderStyle-Font-Bold="true" FooterAggregateFormatString="{0:F2}" FooterStyle-Font-Bold="true" >
<HeaderTemplate>
Total Goal
</HeaderTemplate>
<ItemTemplate>
<a href="HinoPartsDashBoardTransactions.aspx?SalesType=AM&from= <%#ddlStartMonth.SelectedValue%>&to=<%#ddlEndMonth.SelectedValue%>&DMP= <%#Eval("User_ID")%>"><%#Eval("Total_Goal")%></a>
</ItemTemplate>

</telerik:GridTemplateColumn>

Total_Goal Total_sales
0.00 123.67
0.00 4567.89

[Solved] Style not applied to first Menu Item

Hello, I'm new to using the Telerik controls and I haven't had any luck finding an answer to my problem so far. All I'm trying to do is have a different background image for un-selected menu items, selected menu items and hovered menu items. So far I've been able to apply this style to all menu items except for the very first one. I'm not doing any thing different in my code, so I'm wondering if I should be doing something different. In my attached picture, you can see the first menu item (selected) without my background image. The second item has the correct selected style, the third item has the correct un-selected style and the final item has the correct hover style. If it makes any difference, this control is on a master page.

CSS

.NormalMenuItem

{

/*background-color: red !important;*/

background-image: url(../Images/headerNormal.png) !important;

background-size: 100% 35px;

}

.NormalMenuItem:hover

{

/*color: red !important;

background-color: white !important;*/

background-image: url(../Images/headerHover.png) !important;

background-size: 100% 35px;

}

.SelectedMenuItem

{

/*background-color: purple !important;*/

background-image: url(../Images/headerActive.png) !important;

background-size: 100% 35px;

}

C#

DataTable mnuDT = new DataTable();

mnuDT.Columns.Add("Section");

mnuDT.Rows.Add("Employees");

mnuDT.Rows.Add("Projects");

mnuDT.Rows.Add("Customers");

Telerik.Web.UI.RadMenuItem homeRmi = new Telerik.Web.UI.RadMenuItem();

homeRmi.Text = "Home";

homeRmi.CssClass = "NormalMenuItem";

homeRmi.ClickedCssClass = "SelectedMenuItem";

homeRmi.SelectedCssClass = "SelectedMenuItem";

homeRmi.Selected = true;

rmMain.Items.Add(homeRmi);

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

{

Telerik.Web.UI.RadMenuItem rmi = new Telerik.Web.UI.RadMenuItem();

rmi.Text = mnuDT.Rows[i].ItemArray[0].ToString();

rmi.CssClass = "NormalMenuItem";

rmi.ClickedCssClass = "SelectedMenuItem";

rmi.SelectedCssClass = "SelectedMenuItem";

rmMain.Items.Add(rmi);

}

ASPX

<telerik:RadMenu ID="rmMain" runat="server" onitemclick="rmMain_ItemClick">

</telerik:RadMenu>

After Upgrading I get Failed to create designer 'Telerik...

After upgrading I get Failed to create designer 'Telerik.Web..... on all Telerik controls.

The only way I can get the controls to work is to down grade them. What do I need to do to get them to work?

Using Telerik version 2011.1.519.35
only working version looks like 2010.1.519.35 located in the installation folder all other version are in the Download folder.
Using VS2010 Prem, Windows 7 Ent. all service packs installed and up to date.

Thanks.

[Solved] Cancel event using RadAlert

Hi

I'm using a RadAlert from the server side to pop up if there is an issue. I'm using the RadAlert because it gives me 1 button, if it pops up I want the OK click to stop processing the serverside event.

How can I achieve this.

Or if I have to use RadConfirm how do I hide the Close button.

Comma delimited string as datasource

How do I set a comma as the tag separator? It seems my tags are being separated by space, but our tags can contain separator words. For example "Santa Monica,Public Library" is displayed as 4 tags instead of just 2.

Is there something I'm missing here? Seems like this should be the default behavior.

Thanks for your time.

Set selected text

I have a RadDropDownTree and i want to set the selected value, I do this with the ddtDiagCategorie_OnNodeDataBound, my node is selected in the list when i open it, but th text is not dispay at first time, I tried with DefaultMessage property with no result. I was thinking that the right manner was using the SelectedText or SelectedValue like a normal dropdown, but th property is readonly, how does I have to do this. (The big consequence is after a modify, if the user don't go to selecte the value in the DropDownTree, he save an empty value in the database...)

My code on the event :

protected void ddtDiagCategorie_OnNodeDataBound(object sender, DropDownTreeNodeDataBoundEventArguments e)

{

if (BilletCourant != null && BilletCourant.IdCategorie.HasValue)

{

if (e.DropDownTreeNode.Value.Equals(BilletCourant.IdCategorie.Value.ToString()))

{

e.DropDownTreeNode.CreateEntry();

}

//ExpandAllNodes sur ce contrôle

e.DropDownTreeNode.Expanded = true;

}
