radRibbonBar & radApplicationMenu, Cuts Floating Menu

Hi!

I like RibbonBar & radApplicationMenu, Excellent Components, but I have a problem. Under Start main Button there are main Items and RightColumnItems, so my interest is on main Items. I have 3 main items, every one displays popup submenus on right side (when mouse pointer is hover), my problem is because 1st item displays about 20 items on popup submenu but only 3 items is displayed due to (I guess) main container size where start menu is on, I need to show all popup items, how can I do?

Thanks for your help

Checkbox in GridView cant be checked

Hi all,

I have 2 different forms. 1 form(Form A) is to call another form (Form B)
Form B is initiated as a single instance.
Below is the code for Form A:
    public partial class FieldList : Form
    {
        Form CreateField = new CreateField();

        public FieldList()
        {
            InitializeComponent();
        }

        private void radButton1_Click(object sender, EventArgs e)
        {
            CreateField.ShowDialog();
        }
    }

Form B contains a radgridview with checkbox column.
When i click on any checkbox, it still looks fine. But when i close Form B, and opens up again,
the checkboxes in the checkbox column cant be clicked and sometimes when i click on 1 checkbox, another checkbox got checked instead.

Below is the Code for Form B:
public partial class CreateField : Form
    {
        public CreateField()
        {
            InitializeComponent();
            LoadData();
        }

        public void LoadData()
        {
            gvUsers.Rows.Clear();

            // (checkbox column, textbox column, boolean column)
            gvUsers.Rows.Add(false, "User1", false);
            gvUsers.Rows.Add(false, "User2", false);
            gvUsers.Rows.Add(false, "User3", false);
            gvUsers.Rows.Add(false, "User4", false);
            gvUsers.Rows.Add(false, "User5", false);


        }
    }

Has anyone occurs this error before? The form has to be single instance as it is to be used with the SPRING framework.

Thanks and Regards,
Jack

The bug of filter row of RadGridView

Hello,

We encount a problem about the bug of filter row of RadGridView,
when the data type of column is datetime,
I select the "Between" or "Not between" condition of the filter row by the popup menu to
filter the datetime type column,it'll show ""Not enough values"" error message,
then the program crashed,I try the example of Telerik,it occurred the same situation,

I think that Filter Row only allow enter 1 date, but "Between" and "Not between"
must have the option to compare 2 date, so there will be show the "Not enough values" error message.
I use the 2008 Q2 SP1,is this problem fixed in the latest version? if not,how to avoid this problem?

regards.

FormatString problem with swedish culture

Hi!

I'm running a English Windows Vista 32bit, current culture is set to Swedish-Swedish.
In my grid, I have a decimal column with formatstring set to "{0:N2} kr"

When I enter the value 10000 this gets formated to "10,000.00 kr"
Acording to the swedish culture information, it suppose to be formated into "10 000,00 kr"

What am I doing wrong ?

[Solved] RadButtonElement subclass doesn't have correct style

If I subclass RadButtonElement, the subclass no longer has the same style applied as a pure RadButtonElement. Here's the simple code snippet:

                                ...         
                        panel.Children.Add(new RadButtonElement() { Text = "RadButtonElement" });         
                        panel.Children.Add(new MyRadButtonElement() { Text = "MyRadButtonElement" });         
                    }         
                     
                    class MyRadButtonElement : RadButtonElement         
                    {         
                    }         
                     
                     

Can you tell me how to make my RadButtonElement have the same default style (e.g. background color, mouse rollover) as a regular RadButtonElement?

Thanks,

Simple insert, update, delete in Grid

Hi again!

Today I was looking for an Solution to update, insert and delete rows in a grid without a Dataadapter.
I found a few threads, but in the most you told us to wait for the next Version of RadGrid an new Handling of events. (My actual version is Q1 2009)

I need a solution where I can user my own statements and parameters in a Radgrid.
I fill the grid with:

    
            RadGridView1.MasterGridViewTemplate.LoadFrom(reader)

I was logging the RowsChanging and RowsChanged events, but cannot find the right solution for my problem
For example: When I add a new row, the rowChanging event fires with e.action = Telerik.WinControls.Data.NotifyCollectionChangedAction.Add but then no Changing events with Telerik.WinControls.Data.NotifyCollectionChangedAction.ItemChanged is fired for this row

Then I tried to use the CellEndEdit- Event but cannot find a way to know that I'm in a new Row and so on...

Pleas help.

regards
Willi

Check/uncheck all checkboxes of childstemplates

Hello,

Okay I've got a gridview that has 2 levels: parent, child.

Now in both levels I've got a checkbox column.

So I want to check/uncheck all checkboxes in the child level when I clicked on the parent his checkbox.

I got it working I thought but I'm getting some strange behavior. I think I know why, but I have no idea for the moment how to solve it.

okay my code snippet:

                    private void rgvAdserverNetwork_ValueChanged(object sender, EventArgs e)         
            {         
                var cell = sender as GridDataCellElement;         
                if (cell == null || ((GridViewDataColumn)cell.ColumnInfo).FieldName != "Add") return;         
                         
                var viewTemp = cell.ViewTemplate;         
                var tempRow = cell.RowElement;         
                var rowinfo = tempRow.RowInfo;         
                         
                if (!(bool)cell.Value)         
                {         
                    //loop the child items to set the checkbox to true         
                    loopChilds(rowinfo);           
                    rowinfo.Cells["Add"].Value = true; //set the checkbox of the parent to true         
                }         
            }         
                     
            //loop the child items of the given master row         
            private void loopChilds(GridViewRowInfo masterrow)         
            {         
                var childRows = masterrow.ViewTemplate.ChildGridViewTemplates[0].GetChildRows(masterrow);         
                if (childRows == null) return;         
                var length = childRows.Length;         
                     
                var expandedState = masterrow.IsExpanded;         
                masterrow.IsExpanded = true;         
                     
                for (var i = 0; i < length; i++)         
                {         
                    childRows[i].Cells["Add"].Value = true; //set the checkbox of the parent to true         
                }         
                masterrow.IsExpanded = expandedState;         
            }         

Maybe there is a better way to achieve this.

Thanks a lot in advanced.

How to set the padding on a child grid in a hierarchical grid?

The default padding on the default theme for the child grid on a heirarchical grid has a padding box that is quite wide. I'd like to to set it to 0, but the child is created at runtime. How do I access this property?
