I'm trying to use the RadGrid to do in-place editing and I am having an issue.

When press the "+ Add" button, I can enter the fields and when I press save, everything is working fine.  When I try to edit the same record with the "Edit" button below it can't find any of the templated controls. (It's a template column here, but the same thing happens when I use GridEditCommandColumn)

This is the ASCX code:


This is in the code-behind.

 

void gridNotes_ItemCommand(object source, GridCommandEventArgs e)

 

{
    

switch (e.CommandName)

 

    {

 

        case RadGrid.InitInsertCommandName:

 

 

            if (gridNotes.EditItems.Count > 0)

 

                gridNotes.MasterTableView.ClearEditItems();

            NoteID = 0;

 

            break;

 

 

        case RadGrid.EditCommandName:

 

            _gridItem = (

GridEditableItem)e.Item;

 

            NoteID =

Convert.ToDouble(_gridItem.GetDataKeyValue("NoteID"));

 

            e.Item.OwnerTableView.IsItemInserted =

false;

 

 

            break;

 

 

        case "Save":

 

            e.Item.Edit =

false;

 

            _gridItem = (

GridEditableItem)e.Item;

 

            _presenter.SaveNote();

            gridNotes.MasterTableView.ClearEditItems();

 

            break;

 

 

        case "Cancel":

 

            gridNotes.MasterTableView.ClearEditItems();

 

            break;

 

 

        default:

 

            gridNotes.MasterTableView.ClearEditItems();

 

            break;

 

    }

}

In the SaveNote() method, the controls are accessed through properties that look like this:

((RadDatePicker)_gridItem.FindControl("dateNote")).SelectedDate;
((TextBox)_gridItem.FindControl("txtOwner")).Text;

 

 

etc.

I get "Object reference not set to an instance of an object.", because although _gridItem exists, the FindControl() returns null.

 

Hi,
Should the form decorator be able to apply styles to menu items? from my tests it does not seeem to work (Q1 2010 release)

I am using a commandItem Template.
In this row I have added a Show Inactive Checkbox. 
I need the check box to maintain view state when users filter items (see pic) and such. 
The story:

1. A user has a list of sites, some have been set to inactive. 
2. They need to see the inactive sites only.  Why-- to view some of the historical data for that inactive site.
3. In the commandItem Template row I have a checkbox. 
4. They click the check box and it autopostback and tells the datasource (linq to sql datasource) to only show inactive sites.
5. They filter the list and the grid rebinds.
6. The PROBLEM, everytime the grid rebinds the checkbox loses it viewstate.

I search the various online demos and I have not seen this type of example.. Anyone have an idea?

I have a radGrid that shows data from an ObjetDataSource (a query with a join between multiple tables). I have defined on the grid the DataKeyValues (IdCultura, IdMaschera, Nome) and I want to catch a text field inserted by user:


In particular I want to retrieve the edited "Nome" field in grid. In this event I catch correctle the IdCultura and IdMaschera but always the old value and not the new one inserted by user. Why?

I having the problem for edit / insert. The edit form still showing after click on update/ insert button. But, the data can insert to the database.

Okay, I have to be missing something very simple here, but I've banged my head enough and need some help.

I have a user control and a simple master/detail grid placed in it.
I have placed custom filter controls in the header.

Problem:
When the user control loads into my page, the grid is populated just fine (approximately 99 rows returned).  I then select an OrderNumber from my custom filter combo box and the grid rebinds perfectly.  I have one row returned, which is exactly what is expected.  However, when I go to the same combo box filter and select "All", I get no rows returned.  However, while debugging, I can clearly see the datasource being reset to the original 99 rows returned.  I have tried this with NeedDataSource event handling and without (meaning I brute force it to rebind).

I can make this work without any problems if I place the grid directly into an aspx page, but for some reason I'm having a hard time when its inside a user control.

Below is the code pertaining to this issue.  Any help would be appreciated.  One other thing, I have tried turning off viewstate (not really an option since I need viewstate), setting datasources to null, rebinding, not forcing rebind.......etc.....etc......etc....



Now the relevant code behind (this is the way I last tried...brute force):

I've been working on building the filter expression programmatically with success.  What I can't seem to figure out is how to build multiple groups and apply them to the RadFilter.

I have a datatable with rows.  For each row, I'd like to create a group.  Here's what I have so far but it is now working.

I am having a problem which occurs when a user enters text (not valid file path) into the file path text box.  If the user enters plain text (example: test), and then tries to click the 'Close' button on the page - the Close button click event is never fired. 

This also happens on other pages in the project with all the Upload controls.  It seems that anytime a user enters non-file path text into the file path text box, all other buttons on the page are rendered useless until the 'Clear' button for the upload control is called.  We are trying to avoid forcing the user to use the 'Browse' button solely because of keyboard navigation requirements. 

The following is the code used for the Upload control and the button. 

<

 

telerik:RadUpload ID="rulUpload" runat="server" ControlObjectsVisibility="ClearButtons"

 

 

InputSize="50" MaxFileInputsCount="1" ReadOnlyFileInputs="False" Height="25px"

 

 

Width="498px" Localization-Select="Browse" select="Browse" AllowedFileExtensions=".pdf"

 

 

AllowedMimeTypes="application/pdf" MaxFileSize="5242880" EnableFileInputSkinning="False"

 

 

EnableEmbeddedSkins="True">

 

 

</telerik:RadUpload>

 

<

 

asp:Button ID="btnUpload" runat="server" Text="Upload" CausesValidation="true" ValidationGroup="Save"

 

 

OnClientClick="return btnSaveChecks();" />

 

 

&nbsp;<asp:Button ID="btnClose" runat="server" Text="Close" />

 

Has anyone else encountered this problem and is there a way to fix it? 

Hi ,

Good Morning,

I am currently working with the RadListView to display 4 columns from a datasource. This all works fantastic and is quite fast. I had originally been using the grid but found it to be a little overkill as all I need to do is display the columbs, allow selecting of a row and loading some data when that row is selected.

I have also worked with the repeater and datalist control from the standard asp.net toolkit but found they were a bit more difficult to get access to controls within the ItemTemplate definitions.

The problem I am runing into is as follows. I need to be able to do the following (all in javascript)

1. When a user clicks a row I need to be able to set teh background color of the row and turn off any other rows. I realize the RadListView allows for a postback but it only seems available if you include a button in one of the columns to generate a ItemCommand. What I ended up doing was placing an onclick event in each <tr> definition that allows me to call a javascript routine. The problem I have is that I can pass a referene to the row and change the background color, but I cannot find a way to access any of the other rows in the listview. Is there a way to get this collection of rows so I can handle the selection piece myself by setting the background color?

2. In the javascript function when I pass the row reference, how do I get to the controls? I know I can do a get_dataKeyValues I believe it's called and I can access the databound columns. This works great, but what if I have a simple checkbox control that I want to set it's value in the javascript function? How do I get access to this row collection?

3. I will be forcing a postback once a row is selected and I need to load the assocaited data, will this postback allow me to update the ListView control through the radajaxmanager?

The biggest problem is being able to turn off and on the background color for selection. The itemSelect command in RadListView would have been nice but it generates a postback which I do not want to happen since many of my editors are on the client side until the user is ready to submit the final data.

Any help would be appreciated.
