Hello,

Thanks for all the answers to my questions thus far!

This time I'm having trouble setting the alternativerowcolor of a gridview programmatically after setting the datasource. Essentially something like this would be ideal:

radGridView1.TableElement.AlternatingRowColor = Color.Blue;

However, I can see no way of getting to the table element from the gridview, even through the rootelement, mastergridviewtemplate and gridelement properties...

Thanks for the help!

We want to show the close button on some tabs in the PageView, but not all. Can the closebutton visibility be specified pr tab, instead of as a property on the parent PageView?

I'm having problems using themes with Winfoms 2012 Q2, there're not working.
They don't appear in the combobox for the controls and if I manually change them programaticly.. they don't show up during running time.
What am I doing wrong? Is it some kind of bug of Q2, when will it be corrected.

Thank you in advance

Hi

I have a radgridview bounded to a list (i'm using entity framework for my db backend). i have some number and string fields and a list<string> field in my data list.

Now i want to convert that list<string> into comma separated string and then show it in it's grid column.

I know how to convert list into string(via string.join), but i don't know how could i tell to radgrid to show joint string.

So, which event of radgrid is a good place to change column or row data to display?

I mean an event that fires when radgrid is populating columns or rows data(with access to original bounded data).

Please help me.

I have the following forms
1- A MDI Child form which has a ribbon bar
2- A MDI Parent Form which also has a ribbon bar

Is it possible when opening the MDI Child form to have it's ribbon items be merged to the parent form ribbon (first tab)?,
the mdi child will have only one ribbon tab.

I have recently downloaded the the trial version of the Telerik .Net controls (2012 Q1).  I loved the demos but the Telerik controls are corrupting my Visual Studio installations so I can't properly evaluate the product.  In both Visual Studio 2008 and 2010 my toolbox takes on the order of 5-10 minutes to load.  The message I get is "Initializing Toolbox".  I ran devenv /log <filename> and isolated the issues to the Telerik tools.  This is an example of one of the log records.

I also get multiple instances of the Telerik controls showing in my Toolbox.  I have tried uninstalling and re-installing the Telerik controls.  When they were uninstalled Visual Studio ran fine.  After installing them again I had the same issues.  I would really like to evaluate this product but have been wasting a lot of time just trying to get it installed properly.  Is there something I am missing?

Hi! Sometime last year I installed Telerik Winforms Controls, and all worked fine. But then came the updates, and since then it's total chaos. In the toolbox are controls missing, although they're checked in the chooser. Other controls appear 2, 3 or even 4 times in the toolbox. And what's worse; I'm getting error messages such as these all the time:
---------------------------
Microsoft Visual Studio
---------------------------
Cannot find type Telerik.WinControls.Themes.Design.RadThemeDesignerDataAttribute in module Telerik.WinControls.dll.
---------------------------
Can I uninstall the whole thing and is there a download that allows me to re-install everything INCLUDING all updates in one go?

Hoping for a solution, because I'm getting pretty desperate...

hello,
I am manually loading the GridView and in CurrentRowChanged event of the gridView i am trying to fill the set of textboxes and label control with data present in the selected row of the  GridView.
Here are the codes:

1. manually Loading GridView data in a method
 private void loadAllUsers()
        {
          
            var obj = _dataAccess.GetAllMembers();
            if (obj != null && obj.Count > 0)
            {
 
                gvListUsers.Visible = true;
 
                gvListUsers.Columns.Clear();
                gvListUsers.AutoGenerateColumns = false;
                gvListUsers.MultiSelect = false;
                gvListUsers.EnableGrouping = true;
                gvListUsers.EnableCustomGrouping = true;                
                gvListUsers.ShowGroupedColumns = true;
                
 
                gvListUsers.DataSource = obj;
 
                var textBoxColumn = new GridViewTextBoxColumn();
                textBoxColumn.Name = "TextBoxColumn";
                textBoxColumn.HeaderText = "ID";
                textBoxColumn.FieldName = "MembershipID";
                textBoxColumn.Width = 50;
                gvListUsers.MasterTemplate.Columns.Add(textBoxColumn);
 
 
                var txtColumnUsername = new GridViewTextBoxColumn();
                txtColumnUsername.Name = "txtBoxColumnUsername";
                txtColumnUsername.HeaderText = "UserName";
                txtColumnUsername.FieldName = "Username";
                txtColumnUsername.Width = 120;
                gvListUsers.MasterTemplate.Columns.Add(txtColumnUsername);
                             
                var textBoxColumnFirstname = new GridViewTextBoxColumn();
                textBoxColumnFirstname.Name = "TextBoxColumnFirstname";
                textBoxColumnFirstname.HeaderText = "Firstname";
                textBoxColumnFirstname.FieldName = "FirstName";
                textBoxColumnFirstname.Width = 120;
                gvListUsers.MasterTemplate.Columns.Add(textBoxColumnFirstname);
 
                var textBoxColumnMiddlename = new GridViewTextBoxColumn();
                textBoxColumnMiddlename.Name = "TextBoxColumnMiddlename";
                textBoxColumnMiddlename.HeaderText = "Middlename";
                textBoxColumnMiddlename.FieldName = "MiddleName";
                textBoxColumnMiddlename.Width = 120;
                gvListUsers.MasterTemplate.Columns.Add(textBoxColumnMiddlename);
 
                var textBoxColumnLastName = new GridViewTextBoxColumn();
                textBoxColumnLastName.Name = "TextBoxColumnLastName";
                textBoxColumnLastName.HeaderText = "Lastname";
                textBoxColumnLastName.FieldName = "LastName";
                textBoxColumnLastName.Width = 120;
                gvListUsers.MasterTemplate.Columns.Add(textBoxColumnLastName);
 
                var textBoxColumnIsActive = new GridViewTextBoxColumn();
                textBoxColumnIsActive.Name = "TextBoxColumnIsActive";
                textBoxColumnIsActive.HeaderText = "Active";
                textBoxColumnIsActive.FieldName = "IsActive";
                textBoxColumnIsActive.Width = 100;
                gvListUsers.MasterTemplate.Columns.Add(textBoxColumnIsActive);
                //column formating
 
               
            }
            else
            {
                gvListUsers.Visible = false;
            }
        }
2. CurrentRowChanged Event: using this event i am assigning the currentrow data of gridview to different textboxes and label
control.
 private void gvListUsers_CurrentRowChanged(object sender, CurrentRowChangedEventArgs e)
        {
            UpdateInfo(this.gvListUsers.CurrentRow);
        }
 
        private void UpdateInfo(GridViewRowInfo currentRow)
        {
            if (currentRow != null && !(currentRow is GridViewNewRowInfo))
            {
		//gettting error "Object reference not set to an instance of an object."
                this.lblMembershipID.Text = this.GetSafeString(currentRow.Cells["MembershipID"].Value);
		this.txtUsername.Text = this.GetSafeString(currentRow.Cells["Username"].Value);
            }
        }
3.
	private string GetSafeString(object value)
        {
            if (value == null)
            {
                return string.Empty;
            }
            return value.ToString();
        }
4. i am getting "object reference not set to an instance of an object" error when am assigning currentrow
data to the label control and for textbox too. I am unable to track it why i am getting this error.
Kindly suggest me what can be done to resolve this issue.
Thanks!!!!
