Ok, so I’m having a really weird problem with the GridView control in a project I've been working on. I’ve been trying to figure out what is going on all day and I haven’t been able to. Basically I’m trying to swap out the standard DataGridView for the telerik grid. When I put the control on a form or user control it formats the grid really strangely. I haven’t done anything beyond setting the Dock property so it should be set with the default styling’s. I have attached some screen shots showing the problem. The first one is from my project (I attached it to a data source so I can show how the formatting looks), the second is from a brand new project. I did the same thing on each.

Anyone have any thoughts on what this could be? Maybe something is the project is overwriting the theme? I was also having an issue with the standard grid where it wouldn’t allow users to resize the columns, even though the option was set in the user control and explicitly on the form.

My goal is ultimately to put it in a user control but I've also tried directly on a form and both produce the same result.  I've tried toggling read only on and off with no luck. I even checked the read only appearance in the working grid and it doesn't look anything like it. Its definitely enabled and I can pull data back and interact with the grid, it just looks funny. It appears to have all the right functionality but it is acting strange when added to the grid or control. In the designer code it is just doing a dim of the instance instead of a friend withevents as in other controls. I am not able to reproduce the issue in a new project so the more I think about it I wonder if there is something in the guts of the program overwriting something. I just don't know where that could be. Any suggestions would be greatly appreciated. Thank you.

hi dear telerik support team.

i got a problem , i have a radGridView .
in my gridView there is a rowValidating event.
but there is a problem , when the user needs to delete a row, rowValidating fires!

I created a list view using a database. My question is that some of the items are not grouped is there a way i can remove them from the list or even if there grouped not display them?
example: data
fruit
apple red ----(blank)
orange orange soft
tangerine orange soft
banana yellow soft
grape purple soft

1. is there a way i can have just a list of the orange fruits?
2. is there a way to draw the list with just soft type and not display apple.

Three days ago I put a thread here, and suddenly it disappeared ("oops server error"). I'm not going to write my post once again since I am not being payed for it.

Here is a copy from the google cache, and additional attachments. I hope it was just a "server error".

Hi,

I am facing some issues in datagrid checkbox column.

1. I have crated master template an having a checkbox column e.g and it has some child template as well which i create dynamically
           GridViewCheckBoxColumn1.EnableExpressionEditor = False
            GridViewCheckBoxColumn1.FieldName = "DeleteItem"
            GridViewCheckBoxColumn1.HeaderText = "Delete"
            GridViewCheckBoxColumn1.MinWidth = 20
            GridViewCheckBoxColumn1.Name = "radchkDelete"
            GridViewTextBoxColumn4.EnableExpressionEditor = False
It is allowing me to check only one checkbox(row) at a time and when i am trying to check another checkbox(row)  it is unchecking my previous checked column..why this..?
2.I am checking one checkbox and trying to scroll horizontally ..it is clearing my checked column...why this..?
3.I am using some events like
code:
  Private Sub rdgrdvSeachAddUpt_CellEditorInitialized(ByVal sender As Object, ByVal e As Telerik.WinControls.UI.GridViewCellEventArgs) Handles rdgrdvSeachAddUpt.CellEditorInitialized
            Dim lobjMessage As New Message

                    If editorElement IsNot Nothing Then

Can you please help me in point#1,2....

Hi There,

I have a grid which has a custom gridbehavior so that if the user hits Shift+Down the current cell is copied to the next row
if the current row is the last visible row, it creates a new row

that part works ok.

the grid will often have an active filter, and if a user hits shift+down and a new row is created, i'm handling RowsChanged so that i can make the new row match the filter.

despite this happening, the new row still does not show up in the grid, its as if i need to re-apply the filter

can you recommend the best way to handle this?

Thanks,
Matt

can anyone help me ?

Best regards

I had a requirement to place a value (Eg: 160 (100)) on CharSeriesItem label. I would like to have two different font sizes for the values. Please suggest.

C# Code:
ChartSeriesItem item = new ChartSeriesItem();
TextBlock txt1 = new TextBlock();
        txt1.Text = "Test1"
        txt1.Appearance.TextProperties.Font = new Font("Segoe UI", 9, System.Drawing.FontStyle.Bold);
        item.Label.Add(txt1);

       TextBlock txt2 = new TextBlock("txt2");
       txt2.Text = "Test2";
       txt2.Appearance.TextProperties.Font = new Font("Segoe UI", 7, System.Drawing.FontStyle.Bold);
       item.Label.Add(txt2);

Hi,

I've been trying to add images to items in an instance of the RadMenu, and it looks like you don't allow people to set the height or width of an image that is associated with an instance of RadMenuItem? Is there a way to do this, or do you actually have to create individual images, specially sized to 16x16 or whatever, for each of your menu items?

Thanks,

Russ
