Real Time SQL Update

Hello,

Does anyone have an example to do the following?

I have a RadHTMLChart on an ASP.NET form.

I have this bound to the SQL select.

It displays the data in the chart perfectly. No problems.

What I want to do, is make it so that the RadHTMLChart is updated when the data is changed.

I have created a JavaScript iteration, and I call the Repaint on the RadHTMLChart, but this does not appear to query the data again. (I can't tell if that is the problem, or the problem is that the Ajax isn't displaying the results. Not sure how to figure out which is the problem?)

I have looked at the Telerik examples extensively, and I've seen the real time examples regarding static data (Not from SQL) and I've seen the SQL examples that are not real-time. I'm looking for an example that basically puts the two together. A real time way to update the RadHTMLChart when the data is changed.

If this isn't clear, let me know and I'll reword it. Any basic examples that anyone has would be great. I just need something to work off of, because I can't seem to get the results I need from the examples I've found online.

Thank You

Expanding tree to specific node based on query string

Hello,

I have a page that has a treeview that lists our different zip files of data that users can download. When the user click a zip file to download and they are not logged in they are redirected to the login page. After they login they are redirected to the page where my zip files are listed in my treeview. The issue now is the page reloaded and the tree is collapsed. How can I open the tree to the specific node the user clicked on? I can put the node text in a query string and page it back and forth but how can I take the query string and open the treeview?

Thank you

Open RadWindow from within RadGrid template column - image button

On my aspx page I have a RadGrid with the following:

<telerik:GridTemplateColumn HeaderText="View Order Details" UniqueName="OrderDetails">

<ItemTemplate>

<div style="vertical-align: middle; text-align: center;">

<asp:ImageButton ID="btnOrder" ImageUrl="~\Content\Images\list.png" runat="server" Height="25px" Width="25px" OnClick="openOrderDetails_Click"/>

</div>

</ItemTemplate>

</telerik:GridTemplateColumn>

I have also tried replacing the onclick method with the below and calling the relevant switch statement (after putting in the OnItemCommand in the grid) :

CommandName="OrderDetails" CommandArgument='<%# Bind("identity") %>'

I have a test button outside my radgrid and when I click on this the window opens without any issues:

<telerik:RadButton ID="test" runat="server" Text="Test" Skin="MetroTouch" OnClick="openOrderDetails_Click"></telerik:RadButton>

Can anyone help with getting this to open from the button within the grid

Spawn a RadWindow with an editform from a detail grid.

How do you spawn an edit window from a detail grid with info from the grid? I can get the window to come up but I'm not clear on how to pass information from the detail grid to the form like an item id for instance.

Where can I find help with RadGrid

I am trying to figure out how to use a RadGrid in a C# ASP.net 4.5 project that uses data entity framework version 6. I can not seem to find good reliable up to date documentation on how to bind the entity framework to the Gridview. I have started here http://docs.telerik.com/devtools/aspnet-ajax/controls/grid/data-binding/understanding-data-binding/telerik-radgrid-data-binding-basics but can not find and information on using the data entity. I found some documentation and videos that show dropping a data entity control from the toolbox and setting the properties of the control via the smart tag, but that functionality is not available in the 4.5 framework.

Can some please provide some good resources that can assist me in transitioning from an ASP.net Gridview to the Telerik RadGridview?

Thanks

Additional Connectors

We are attempting to use the Telerik Diagram to create a Living Value Stream. The Value Stream has connectors between each process on the traditional path, however there are also an additional connectors for a special process that does not go down the traditional path. (I have attached a screen shot of a portion of the Value Stream.)

Is it possible to do this?

Thank you for your assistance.

Double server validate with CustomValidator in RadGrid

Why when I'm using asp.net CustomValidator inside Insert/Edit ItemTemplate column of my RadGrid, the ServerValidate method is fired two times ?

I'm using telerik version 2015.3.930.45

Example:

Asp.net

<telerik:GridTemplateColumn UniqueName="ProductName" HeaderText="Product">

<ItemTemplate><%# Eval("ProductName") %></ItemTemplate>

<EditItemTemplate>

<asp:TextBox Id="ProductNameText" Text='<%# Eval("ProductName") %>' runat="server"/>

<asp:CustomValidator ID="ProductNameValidator" ControlToValidate="ProductNameText" Text="*" ErrorMessage="*" OnServerValidate="ProductNameValidator_OnServerValidate" runat="server"/>

</EditItemTemplate>

</telerik:GridTemplateColumn>

C#

protected void ProductNameValidator_OnServerValidate(object source, ServerValidateEventArgs args)

{

var newProductName = args.Value;

args.IsValid = _myProducts.All(x => x.ProductName != newProductName);

}
