The values entered are not posted back to the server

Hi,

I got another problem when using Telerik RadFilter control. On the Web page, I added a button under the filter. When the button is clicked, I display the expressions in a string (similar to the Preview function, but I disabled the preview function in order to allow the user to edit the string). I tested and my function works fine, but got some problem with the value of the filter expressions.

From UI, I added an Contains expression, selected "PersonName" as the field, entered the value "test", and then clicked my button, it showed "(PersonName Contains '')" without the string "test". I ran the code in DEBUG mode and found that the Value of the RadFilterContainsFilterExpression is NULL, the string "test" is not posted back to the server.

If I set the AllowFilterOnBlur property to false, all the values I entered are not posted back to the server. If I set the AllowFilterOnBlur property to true, only the last value I enterred is not posted back to the server.

How can I make the value posted to the server? Please help.

Many thanks

Bruce

Invoking a javascript window.open() from an ajax grid command postback

Hi,

I am replacing an old control suite with Telerik and the intention initially is to replace like for like with the functionality.

I have a RadGrid that is using a RadAjaxManager to control the ajax postback to display and hide hierarchy data.

In the DetailTable (inner part of hierarchy) I have a command that will postback to check what security the user has and if they have appropriate authorisation the page will fire Javascript to open a window, passing some query string variables set during the postback processing.

The problem I have is that with the AJAX enabled, when I click the command the loading panel fires and then a Javascript error appears, but no popup window. Below is a simplified attempt at registering javascript which does not work. This approach seemed to have been recommended elsewhere on the net.

RadScriptManager.RegisterStartupScript(Page, GetType(), "test", "alert('test');", true);

Error message from IE:
Sys.WebForms.PageRequestManagerServerErrorException: Object reference not set to an instance of an object.

Could anyone advise how I can fire Javascript during an ajax enabled partial page postback?

Thanks for your help,

Matt

FormatBlock not displaying current selection consistently

In IE, the FormatBlock displays selected headings correctly by showing Heading 1, Heading 2, etc. if an h1 or h2 are selected. In Firefox and Chrome, when you select an h1 or h2 it displays "h1" or "h2" as the FormatBlock selected valued. Shouldn't the FormatBlock show the predefined options if their element is selected?

Fully customized CommandItemTemplate, changing Caption position and style

Hello.
I've created my own CommandItemTemplate and put some custom buttons there, but I still want the caption of mastertableview to be placed in the same TD as buttons, with custom CSS style. How to manage this? Right only I indicate Caption property - radgrid adds additional TR above my command item template with caption centered :(

p.s. How to add custom attribute to MasterTableView? I've inherited from GridTableView. But seems like the same approach with public properties and saving in ControlState that worked out for RadGrid does not work here - setter for new property is not called :(

[ToolboxData("<{0}:DSGridTableView runat=server></{0}:DSGridTableView>")]

public class DSGridTableView : GridTableView

{

public DSGridTableView()

{

}

public DSGridTableView(RadGrid owner)

: base(owner)

{

}

//public new string Caption

//{

// get

// {

// return string.Empty;

// }

//}

[DefaultValueAttribute("")]

[PersistenceMode(PersistenceMode.Attribute)]

public string Title

{

get

{

return (ControlState["Title"] == null ? string.Empty : (string)ControlState["Title"]);

}

set

{

ControlState["Title"] = value;

}

[DefaultValueAttribute("")]

[PersistenceMode(PersistenceMode.Attribute)]

public string TitleCssClass

{

get

{

return (ControlState["TitleCssClass"] == null ? string.Empty : (string)ControlState["TitleCssClass"]);

}

set

{

ControlState["TitleCssClass"] = value;

}

Group by resource with custom Advanced Form

Hello Telerik,

We have followed the example to Replace the Edit Form and have had decent success so far. We now have a customized Advanced Form appearing in a RadWindow.

We would next like to group the appointments by a resource on the scheduler, but I'm not sure how this can be achieved - we are aware of the example provided for grouping by resource, but it assumes the developer is using the default templates.

What happens in the case that a custom advanced form is being used?

Regards
