Edit Columns in Dynamically generated Grid

Hello All,

My requirement is as follows. i need to edit a dynamically generated grid ( in which in which i cannot write a editcolumn template) , because i cant define how many columns will be coming. Functionality is as follows, i have Employee leave data, in grid I need to show Empid, DOJ, Name, Leave Type1, Leave Type2, Leave Type3......... as defined in masters. When i load the grid i get all emp details and leave types as columns names, here i need to enter values in each type for each employee. When i bring the grid into edit mode I should not be able to edit first three columns and all others should be in edit mode.

Hope I am clear. Can this be done.

Default button actions not working on edit for update/cancel

The ENTER and ESC keys aren't working in edit mode. I do have another button in the form (outside of the grid) that I focus when the user first hits the page, but I would like the ENTER and ESC keys to work for Update and Cancel.

I already blocked the Enter key using info from this thread: http://www.telerik.com/community/forums/aspnet-ajax/grid/enter-key-hit-on-the-textbox-in-the-radgrid.aspx

Any idea how to make this work?

Thanks,
Andy

Parameter?

Hello, I have a big Problem. I call the Fileexplorer with the Button from client side:

    
            function OpenFileExplorerDialog(val) {  
        
                        _globobjectartselect = val;  
        
                        var wnd = $find("<%= ExplorerWindow.ClientID %>");  
        
                        wnd.set_navigateUrl("../../filemanager/explorer.aspx?search=" + val);  
        
                        wnd.show();  
        
                    }  
        
            function OnFileSelected(wnd, fileSelected) {  
        
                        switch(_globobjectartselect)  
        
                        {  
        
                            case "Picture":  
        
                                var textbox = $find("<%= txtPictureFilePath.ClientID %>");  
        
                                textbox.set_value(fileSelected);  
        
                                break;  
        
                            case "Video":  
        
                                var textbox = $find("<%= txtVideoFilePath.ClientID %>");  
        
                                textbox.set_value(fileSelected);  
        
                                break;  
        
                        }  
        
                    }

I pass a parameter to the link wnd.set_navigateUrl(). This parameter is to set the search pattern.

Fileexplorer:

    
            protected void Page_Load(object sender, EventArgs e)  
        
                {  
        
                    if (Request.QueryString["search"] != null && Request.QueryString["search"] != "")  
        
                    {  
        
                        switch (Request.QueryString["search"])  
        
                        {  
        
                            case "Picture":  
        
                                string[] patterns1 = { "*.jpg", "*.jpeg", "*.gif", "*.png", "*.bmp" };  
        
                                RadFileExplorer1.Configuration.SearchPatterns = patterns1;  
        
                                break;  
        
                            case "Video":  
        
                                string[] patterns2 = { "*.mpg", "*.mpeg", "*.avi", "*.divx", "*.wmv" };  
        
                                RadFileExplorer1.Configuration.SearchPatterns = patterns2;  
        
                                break;  
        
                        }              
        
                    }  
        
                }

This works fine for one call. When i call the picture object first then its ok. In the second call the search patterns are soon the patterns from Picture. The Explorer does not load the new settings.

How can I solve the problem? Its very important for me.

Thank you

Reiner

[Solved] The Telerik.Web.UI.WebResource.axd handler can return uncompressed content for browsers that accept gzip encoding and vice versa

PROBLEM

The Telerik.Web.UI.WebResource.axd handler can return uncompressed content for browsers that accept gzip encoding and vice versa

SOLUTION

Either upgrade your Telerik.Web.UI assembly to version 2009.3.1118 or higher.

Or, add this code to your Global.asax file:

C#

protected void Application_PostRequestHandlerExecute(object sender, EventArgs e)

{

HttpApplication app = (HttpApplication)sender;

if (!app.Request.RawUrl.Contains("Telerik.Web.UI.WebResource.axd"))

return;

HttpCachePolicy cachePolicy = app.Response.Cache;

cachePolicy.VaryByHeaders["User-Agent"] = true;

}

VB.NET

Protected Sub Application_PostRequestHandlerExecute(sender As Object, e As EventArgs)

Dim app As HttpApplication = DirectCast(sender, HttpApplication)

If Not app.Request.RawUrl.Contains("Telerik.Web.UI.WebResource.axd") Then

Return

End If

Dim cachePolicy As HttpCachePolicy = app.Response.Cache

cachePolicy.VaryByHeaders("User-Agent") = True

End Sub

UPDATE (11/18/2009): The Accept-Encoding header has been removed from the VaryByHeaders property as this is preventing Internet Explorer 6 from caching the response.

Programmatic and Autogenerated Columns

Hello,

I'm working on a webpage that contains, among other controls, a dropdownlist and a radgrid. Whenever an item is selected in the dropdownlist, inside the event handler the radgrid uses that selection to retrieve its data.

The radgrid always contains a clientselectcolumn and two button columns (Edit and View). Beyond those "constant" ones the rest of the columns are based on the retrieved data, and they vary. The data columns are sortable, resizeable, and reorderable. The grid is also filtered from the codebehind.

I am also loading and saving column information for these data columns (size, order, etc) associated with the ddl selection. Sometimes the columns do have saved settings for the ddl selection, and sometimes they do not (for these I apply some default settings values).

I have tried a number of different approaches from the various RadGrid examples and postings, but none entirely match what I'm doing, and none entirely work. I am having page lifecycle problems and/or postback problems (some things work and some things don't).

Generally, what kind of approach would you suggest here? Particularly:

How should the "constant" columns be created (in aspx, in the codebehind/at what point, or...)?
How should the data columns be generated and at what point (autogenerated, programmatically/at what point...)?
When should any saved column settings be applied (at databound, at creation time...)?
How do I keep from losing the constant columns on a postback, say, on column reorder?

I appreciate any insight you can provide. Please let me know if I need to provide more information.

Thanks!

DropDownList validation not working

I have a DropDownList and a required field validator. When the form decorator is on, the validation always thinks the selected value is blank. When I turn off the form decorator, everything works fine.

How can I fix it?
