[Solved] Retrieving primary key from Grid

Hello!

I need help figuring out how to pass the primary key value to the btnSave inside an EditForm. What I'd like to do is to get the primary key as a CommandArgument so I do some logic with it, but what I get is an error that the input string was not in a correct format with a following line in codebehind as a problem:

int value = Convert.ToInt32(e.CommandArgument);

Here is the codefront:

<telerik:RadGrid ID="gvKontakti" runat="server" AllowPaging="True" AllowSorting="True"

CellSpacing="0" GridLines="None" DataKeyNames="idKontakt" AutoGenerateColumns="false"

kontakt.Ime = txtIme.Text;

kontakt.Prezime = txtPrezime.Text;

}

else

db.SaveChanges();

}

Any help would be appreciated.

AutoPostBackOnFilter only for return and click

If you set the AutoPostBackOnFilter = true the filtering will start when you hit return, or click the filter button, but unfortunately, it will also start as soon as the filter goes out of focus (you move focus to something else) which prevents you from entering more than one search criteria before the filtering starts. How do you make it so that only return and click on filter image fires the filterning event?

Are we the only ones thinking that the "fire event when the filter textbox goes out of focus" is a strange default behaviour, or have we missed something here? I would say that pressing return or clicking on the filter image should be the default.

Opening RadWindow from the server

The RadWindow is a client-side object – its UI is created when it is first shown and this is the point when the CSS and scripts are loaded as well. This means that it should be used on the client via JavaScript, yet it turns out that it is a very common scenario that the developer wishes to initiate the RadWindow’s showing from the code-behind.

The VisibleOnPageLoad property should not be used for this purpose. It is a behavior property which will result in the RadWindow opening every time the page is post back.

Quite often the VisibleOnPageLoad property gets set to true while the intention is that the RadWindow should only show once. Doing so will result in the RadWindow reopening if a postback is initiated from another element from the page, which is rarely the desired behavior. Also, this approach will not work in case this happens in an AJAX request and the RadWindow is not included in the partial page update.

There are several ways to work around this:
1) Register a JavaScript function from the server-side and do not use the VisibleOnPageLoad property, for example:

<telerik:RadWindow runat="server" ID="RadWindow1" NavigateUrl="http://google.com/"></telerik:RadWindow>

<asp:Button ID="Button1" Text="open the RadWindow from the server" runat="server" OnClick="Button1_Click" />

C#

protected void Button1_Click(object sender, EventArgs e)

{

//business logic goes here

string script = "function f(){$find(\"" + RadWindow1.ClientID + "\").show(); Sys.Application.remove_load(f);}Sys.Application.add_load(f);";

ScriptManager.RegisterStartupScript(Page, Page.GetType(), "key", script, true);

}

VB:

Protected Sub Button1_Click(sender As Object, e As System.EventArgs) Handles Button1.Click

'business logic goes here

Dim script As String = "function f(){$find(""" + RadWindow1.ClientID + """).show(); Sys.Application.remove_load(f);}Sys.Application.add_load(f);"

ScriptManager.RegisterStartupScript(Page, Page.GetType(), "key", script, True)

End Sub

2) Reset the VisibleOnPageLoad property to false with code when suitable, depending on the particular scenario

3) Set EnableViewState to false for the RadWindowManager that contains the desired RadWindows

Chrome/Safari context menus don't do anything

I'm using the most updated version of Q1 2009 and in Chrome 3 and Safari 4, when I click on an image, the resize handles don't appear and when I right click on an image, the context menu shows up, but when I click on any of the menu items, the menu disappears and nothing happens.
