I have a GridView that I populate manually using OpenFileDialog...

        Dim fname As String = ""

        If (dlgImportClients.ShowDialog() = Windows.Forms.DialogResult.OK) Then
            fname = dlgImportClients.FileName
        End If

        Dim TextLine As String = ""
        Dim SplitLine() As String

        If System.IO.File.Exists(fname) = True Then
            Dim objReader As New System.IO.StreamReader(fname)

            Do While objReader.Peek() <> -1
                TextLine = objReader.ReadLine()

                'need to add false for checkbox column
                TextLine = "False," + TextLine

                SplitLine = Split(TextLine, ",")

                dgvClients.ColumnCount = SplitLine.Count
                dgvClients.MasterGridViewTemplate.AllowAddNewRow = False
                dgvClients.ReadOnly = False
                dgvClients.Columns(0).IsVisible = True

                'if .RowCount = 0 then we are processing the first row
                If dgvClients.RowCount = 0 Then
                    For i = 1 To SplitLine.Count - 1
                        With dgvClients
                            .Columns(i).HeaderText = SplitLine(i).ToString
                            .Columns(i).BestFit()
                        End With
                    Next
                End If
                dgvClients.Rows.Add(SplitLine)
            Loop

            'stupid but the only way I could get the datagridview to populate correctly
            If dgvClients.RowCount > 1 Then
                dgvClients.Rows.RemoveAt(0)
            End If
        Else
            RadMessageBox.SetThemeName("Breeze")
            RadMessageBox.Show("File Does Not Exist")
        End If

I am loading the .CSV file to the GridView so that it can be reviewed, cleaned up, and then imported into Clients table within the customers database.

I'm kinda stumped as to the best way to get the data in the GridView into the database. Could just be a brain fart or I may be going about this totally wrong. Any insight would be greatly appreciated.

Hi, I have a question...
I'm using ADO Entity FrameWork and displays information in a GridView, all filters work correctly...
When I get the information with the Entity Framework, I put a top... I mean, if i have 50 records in a table, only I get 20.
Code:
var table = Context.Table.Top(20);
GridView1.DataSource = table;

I want to do is put other filter options (custom filter) in the menu of filters to obtain the others 30 records. I mean, how can I put other options in the menu filter and specify my own code to make another type of filter?

because The default filters only filter the records displayed.

my apologies for my english I hope to have explained..
Thanks!!

Hi!

I have got a datetimepicker (the textbox) with a theme created by me. I have also got a calendar with a theme created by me.

I want to use this calendar with the datetimepicker.

At the moment I have the datetimepicker and when I click on its box appears the default calendar theme and I would like to appear my one I have mentioned before.

How can I do this?because as far as I know with visual style builder when I try to make changes in the datetimepicker properties is not possible to change the calendar which is joined to it.

I hope you have understood what I want to get.

Thank you in advance.

After upgrading my project Q1 2009 SP1 when I bring up the designeer I receive all kinds of errors about no such property registered for various rad controls (such as RadButton, RadScrollBarElement, etc.)

The project will compile and run howerver.  What can I do to correct this.

I've looked around, but I can't seem to find either a text property to change the text, or a property to just hide the auto-created "Click here to add new row" Row in an empty GridView.

I'm using a RadGridView control to display data that comes from a hand held scanner and is created on the fly.  Because of this, I have no data source for the grid, I just define the columns and use AddRow() to display my data. The grid also allows editing of the data in the gird before saving.

Is there a way to turn this off?

I'm trying to evaluate Telerik WinForm controls for our organisation with potential for large license purchase.

I've created a simple Form which inherits from RadForm and added a RadRibbonBar. I need to hide the RadForm title so that the ribbon bar appears correctly, however when I maximize the Form the RadForm menu reappears incorrectly at the very top of the screen, showing only half of the title bar (it should be invisible). I've tried using the RadRibbonForm template with the same results. I've tried searching the forums but without much success. This looks like a bug! Any suggestions?

Environment:
Visual Studio 2008 / NET 3.5
o/s: Windows Vista

I previously had Q3 2008 installed updated to Q1 2009 and now the save/load layout do not work. Actually the save works and creates the layout file but the load has no effect. Work fine before the update. Also noticed the demo only has a Save button, no Load button....

 

Can someone confirm that the load layout is broken or if I need to keep diggin..

the program doesn't crash, its just on this piece of code that I get the error message:


before the while loop wasn't there and only existed with one line of code : rgvAllItems.MasterGridViewTemplate.Columns.Clear();

after some advice here on the forum to change it with the while loop I still got the same error message.
Strange thing is that the count of the columns is greater as zero so this should be giving any problems?

got the same message with this piece of code:
           
just clearing the gridview for a rebind of other data, which is done without a problem. But I'm getting these errors in my log file on regular basis. So I'm curious what is happening since I have no idea If I'm doing something wrong here or not.

thanks in advanced

Hello,

In my hierarchy gridview I have a columncombobox in my heading of my grid. So when I select a value in the combobox it is set to the hole structure of my grid.
Now I was wondering and I added it, that if I select more then one row and select a value of the combobox the value is being set only to the selected items in my grid.

All goes well until I selected an item to much. I wanted to deselect it, but that doesn't work. I need to select an item that isn't select.
But now all items are unselected except of one item. I searched on how I should handle this. but I didn't find it.

thanks in advanced

Hi

How do I clear previously created conditional formatting items from the ConditionalFormattingObject

Which were created using:

Dim con1 As ConditionalFormattingObject = New ConditionalFormattingObject("white rule", ConditionTypes.Contains, Me.RadTextBox1.Text.ToLower, Me.RadTextBox1.Text.ToLower, True)

            c1.RowBackColor = Color.Green

            RadGridView1.MasterGridViewTemplate.Columns.FindByDataField("Country").ConditionalFormattingObjectList.Add(c1)

Thanks

Joe
