Can't get unchanged value of item in rad grid

I have a rad grid and I'm using the pop up window for edit mode. I'm just trying to get the value of every control and update the database. The problem is, if the item has not been changed, the value of the text box is just nothing. I've read through some of your examples, but they seem way over complicated. Is there a simple way to just get the text of the text box within the edit window, whether or not it has been changed? here is my code.

protected void radgridUpdate(Object source, Telerik.Web.UI.GridCommandEventArgs e)

{

RadTextBox track = (RadTextBox)e.Item.FindControl("trackNameInputGrid");

Response.Write(track.Text);

}//radgridUpdate

<telerik:GridTemplateColumn DataField="trackName" HeaderText="Track Name" SortExpression="trackName"

UniqueName="trackName" >

<ItemTemplate>

<asp:Label ID="trackNameOutput" runat="server" Text='<%# Bind("trackName") %>'></asp:Label>

</ItemTemplate>

<EditItemTemplate>

<telerik:RadTextBox ID="trackNameInputGrid" Runat="server" Value='<%# Eval("trackName") %>' >

</telerik:RadTextBox>

</EditItemTemplate>

</telerik:GridTemplateColumn>

CompositeScript & Google jQuery

I am wondering if someone could provide some insight and direction.... For performance reasons I am trying to use a composite script & I am wanting to point my users to use Google's jQuery version so my end users don't have to download it again.

I followed your instructions to make RadControls use an external jQuery. I then tried to 'compositescript' the rest of my external JS references. As folows:

<asp:ScriptManager ID="ScriptManager1" runat="server" EnableCdn="true">
<Scripts>
<asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.Core.js" />
<asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.jQuery.js" Path="http://ajax.googleapis.com/ajax/libs/jquery/1.6.2/jquery.min.js" />
<asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.jQueryPlugins.js" />
</Scripts>
<CompositeScript>
<Scripts>
<asp:ScriptReference Path="/js/some.jquery.plugin.js" />
<asp:ScriptReference Path="/js/another.jquery.plugin.js" />
</Scripts>
</CompositeScript>
</asp:ScriptManager>

This fails, because SM renders the compositeScript first which means jQuery isn't loaded yet and the plugins fail. I can't figure out any way around this....

Is there a solution?? Or do you have other tips to make this run better. I don't have RadControls on every page of this website, but do use jQuery on every page. I am keen on the compositeScript because I have many many plugins and UI files. For now I'm resorting to manually combining and minifying.

Any workaround, tips or suggestions on how to tune this the best would be appreciated.

Duplicate RadGrid

Hello,

I am very new to ASP.Net, and I'm sure that my problem has more to do with how I implemented the updatepanel, rather than how I implemented the grid.

I have a page with two UpdatePanels. The first holds a bunch of dropdowns that get changed whenever a selection is changed. The second UpdatePanel holds a button and a RadGrid. When someone hits the button, the server is supposed to perform a query and update the grid's databinding.

Instead, when I hit the button, a second identical grid appears right next to the first one. The original grid gets the data, and the duplicate grid has no data. If I hit the button again, I get the error, "Uncaught Sys.WebForms.PageRequestManagerServerErrorException: Sys.WebForms.PageRequestManagerServerErrorException: Invalid JSON primitive: ."

Drag Drop row to empty grid

I have multiple grids, and the user can drag and drop rows from one to another. I am making use of OnRowDropping to call webservices, trigger rebinds, etc. All is working perfectly.... except when the user drops a row from one grid on to an empty grid containing only the NoRecordsTemplate. The event is raised, but the "args" object contains null for all the "target" values.... i.e.

_targetItemTableView, etc. The destinationHtmlElement is populated, so I use this to navigate backwards to find the Grid, but the lack of "target" info in this situation seems to be a bug to me.

[Solved] Style TreeListFooterItem with Parent node Properties

I need the ability to style each footer item with specific criteria from the parent node. The attached screen shot is partially what I need, but instead of having the root node be formatted on every total line, I need each aggregate to be formatted with that parent's name. Is this possible?

Find Control Edit Template

I have a TreeList with an Edit Form Template. How do I go about finding those controls when the edit form is opened? With the RadGrid I could find these controls by using the ItemDataBound event and checking if the item is in edit mode. Is there a similar way to do this with the TreeList control?

Thanks.
