Application of filter causes an error

Hello,

I have used a Telerik gridview in my winform. I have enabled paging & filter for the grid by default. After successful data binding with grid, when I apply filter to any column i.e select any specific option or specify specific condition than I get an un-handled exception. Please review the below steps for bug reproduction.

RadarChart - Setting line thickness and color

Hi again,

I have successfully implemented a radar area line chart as per attached image. I have the following questions:

(a) How I can programmatically change the thickness of the displayed line?

(b) How I can change the colour of each category line depending on the value, e.g. value =100 will be red, value =10 will be blue and so on.

Regards,

George

RichTextBox

Hi there,

I'm trying the RichTextBox and something doesn't seem right. In the properties window if I add a value for the Text property and run the app it doesn't show.
Same if I dynamically add a RichTextBox at runtime and try and apply a value to the text property... nothing shows up.

Questions:
1. Why doesn't the text property work?
2. Does winforms come with the equivalent of Asp.net for Ajax RadEditor and is RichTextBox it?

Regards,
Jacques

Issues with DefaultValuesNeeded event

On adding new row in RadGridView, I am assigning DefaultValues in DefaultValuesNeeded event. When I start typing in the new row, the default values appear but the moment I hit enter on the row ( so that it is added to the current grid ) , all the default values just disappear.
I have created columns dynamically.

Please tell me what is the issue or am I missing anything ?

Below is my code.

grid code:

private void BindGrid()

{

this.ExportSettingGridView.AllowAddNewRow = false;

this.ExportSettingGridView.AutoGenerateColumns = false;

this.ExportSettingGridView.AutoSizeColumnsMode = GridViewAutoSizeColumnsMode.Fill;

this.ExportSettingGridView.ShowGroupPanel = false;

this.ExportSettingGridView.MasterTemplate.EnableGrouping = false;

this.ExportSettingGridView.EnableHotTracking = true;

//Settings Name column

GridViewTextBoxColumn nameCol = new GridViewTextBoxColumn();

nameCol.FieldName = "Name";

nameCol.Name = "Name";

nameCol.HeaderText = "Export Setting";

this.ExportSettingGridView.Columns.Add(nameCol);

//Settings Na Option Combo Box

GridViewComboBoxColumn naDataOptionCol = new GridViewComboBoxColumn();

naDataOptionCol.FieldName = "NaData.NaDataOption";

naDataOptionCol.Name = "NaData.NaDataOption";

naDataOptionCol.HeaderText = "NA Data Option";

naDataOptionCol.DataSource = Enum.GetValues(typeof(NADataOption));

naDataOptionCol.DataType = typeof(NADataOption);

naDataOptionCol.DataSourceNullValue = NADataOption.BLANKROW;

this.ExportSettingGridView.Columns.Add(naDataOptionCol);

//Setting NA Option Custom Text field Columns

GridViewTextBoxColumn naDataOptionCustomCol = new GridViewTextBoxColumn();

naDataOptionCustomCol.FieldName = "NaData.Custom";

naDataOptionCustomCol.Name = "NaData.Custom";

naDataOptionCustomCol.HeaderText = "NA Data Option Custom";

this.ExportSettingGridView.Columns.Add(naDataOptionCustomCol);

//Setting IncludePartialLastPeriod

GridViewComboBoxColumn includePartialLastPeriodCol = new GridViewComboBoxColumn();

includePartialLastPeriodCol.FieldName = "IncludePartialLastPeriod";

includePartialLastPeriodCol.HeaderText = "Include Partial Last Period";

includePartialLastPeriodCol.Name = "IncludePartialLastPeriod";

includePartialLastPeriodCol.DataSource = new String[] { "True", "False" };

includePartialLastPeriodCol.DataType = typeof(bool);

this.ExportSettingGridView.Columns.Add(includePartialLastPeriodCol);

//Setting Sorting Column

GridViewComboBoxColumn sortingCol = new GridViewComboBoxColumn();

sortingCol.FieldName = "Sorting";

sortingCol.HeaderText = "Sorting";

sortingCol.Name = "Sorting";

sortingCol.DataSource = new String[] { "ASC", "DESC" };

this.ExportSettingGridView.Columns.Add(sortingCol);

//Setting Data Load Position

GridViewComboBoxColumn dataPostionOptionsCol = new GridViewComboBoxColumn();

dataPostionOptionsCol.FieldName = "DataLoadPosition.CursorLocation";

dataPostionOptionsCol.Name = "DataLoadPosition.CursorLocation";

dataPostionOptionsCol.HeaderText = "Cursor Location";

dataPostionOptionsCol.DataSource = new String[] { "True", "False" };

dataPostionOptionsCol.DataType = typeof(bool);

dataPostionOptionsCol.DropDownStyle = Telerik.WinControls.RadDropDownStyle.DropDownList;

this.ExportSettingGridView.Columns.Add(dataPostionOptionsCol);

//Setting Data Load Cell location

GridViewTextBoxColumn cellCol = new GridViewTextBoxColumn();

cellCol.FieldName = "DataLoadPosition.Cell";

cellCol.Name = "DataLoadPosition.Cell";

cellCol.HeaderText = "Cell Location";

this.ExportSettingGridView.Columns.Add(cellCol);

this.ExportSettingGridView.BestFitColumns();

}

          private void newButton_Click(object sender, EventArgs e)

          {

            this.ExportSettingGridView.AllowAddNewRow = !this.ExportSettingGridView.AllowAddNewRow;

          } 



        private void ExportSettingGridView_DefaultValuesNeeded(object sender, GridViewRowEventArgs e)

        {

            if (e.Row != null && e.Row is GridViewNewRowInfo)

            {

                e.Row.Cells["NaData.NaDataOption"].Value = currentProfile.NaData.NaDataOption;

                e.Row.Cells["NaData.Custom"].Value = currentProfile.NaData.Custom;

                e.Row.Cells["DataLoadPosition.CursorLocation"].Value = currentProfile.DataLoadPosition.CursorLocation;

                e.Row.Cells["DataLoadPosition.Cell"].Value = currentProfile.DataLoadPosition.Cell;

            }

        }

How to maintain multilevel hierarchy in GridView

hello everyone..
am using telerik radGridView for windows forms. I need to have atleast of 3 levels of hierarchy in my grid. And, it is essential for me to follow "Load-on-Demand" method to bind the inner grids.
Currently am doing this:

private void Form2_Load(object sender, EventArgs e)
{
this.radGridView1.MasterTemplate.AutoSizeColumnsMode = GridViewAutoSizeColumnsMode.Fill;

//First Child Template Begins

GridViewTemplate firstLevelTemplate = new GridViewTemplate();
firstLevelTemplate.Columns.Add("Name", "Name", "Name");
firstLevelTemplate.Columns.Add("Owner", "Owner", "Owner");
firstLevelTemplate.Columns.Add("Parent", "Parent", "Parent");

//First Child Template Ends

this.radGridView1.Templates.Add(firstLevelTemplate);
this.radGridView1.Templates[0].HierarchyDataProvider = new GridViewEventDataProvider(firstLevelTemplate);
this.radGridView1.RowSourceNeeded += new GridViewRowSourceNeededEventHandler(radGridView1_RowSourceNeeded);
}

void radGridView1_RowSourceNeeded(object sender, GridViewRowSourceNeededEventArgs e)
{
string serverInstance = e.ParentRow.Cells[0].Value.ToString();
ServerConnection conn = new ServerConnection();
conn.ServerInstance = serverInstance;
Server srv = new Server(conn);

DatabaseCollection DBs = srv.Databases;
foreach (Database db in DBs)
{
GridViewRowInfo row = e.Template.Rows.NewRow();
row.Cells[0].Value = db.Name;
row.Cells[1].Value = db.Owner;
row.Cells[2].Value = db.Parent.Name;

e.SourceCollection.Add(row);
}

}

It beautifully adds the two levels! I want a third level now. How to do that?? I tried adding GridViewTemplate to e.Template.Templates, but no luck..please help me..
