How to link two columns with different datasources

I have run into an interesting issue.

I have a datagrid that I have linked to an OrganizationName data source. Inside the OrganizationName object, we have setup a link to another object called OrgnanizationNameType.

On the datagrid, I want to have two columns. The first column is linked to the OrganizationName data source and the second column is linked to the OrganizationNameType data source.

When the datagrid loads, I need to to have the value of the OrganizationNameType to be linked to the value inside the OrganizationName object. I need this done in a drop down for easy editing.

Is this possible?

RadPopupForm

Hi!

I've reinstalled my computer, and now my project won't build.
"The type or namespace name 'RadPopupForm' could not be found (are you missing a using directive or an assembly reference?)"

I'm using VS 2005 and WinForms 2010.1.10.308_dev

If I comment out this section, everything else is ok. And it was ok before reinstalling windows7.

    
                    private void radComboBoxAgreement_DropDownOpened(object sender, EventArgs e) 
        
                    { 
        
                        //getting the popup form which size should be set   
        
                        RadPopupForm popup = (RadPopupForm)radComboBoxAgreement.Items[0].ElementTree.Control; 
        
                        int desiredWidth = (int)radComboBoxAgreement.ComboBoxElement.ListBoxElement.Viewport.DesiredSize.Width; 
        
                        RadScrollLayoutPanel scrollPanel = (RadScrollLayoutPanel)radComboBoxAgreement.ComboBoxElement.ListBoxElement.Children[2]; 
        
                        if (desiredWidth > radComboBoxAgreement.Width) 
        
                        { 
        
                            if (scrollPanel.CanVerticalScroll) 
        
                            { 
        
                                desiredWidth += radComboBoxAgreement.ComboBoxElement.ListBoxElement.ScrollThickness; 
        
                            } 
        
                            //adding border width (both left and right) of the inner listbox element.    
        
                            desiredWidth += radComboBoxAgreement.ComboBoxElement.ListBoxElement.BorderThickness.Horizontal; 
        
                            popup.Size = new Size(desiredWidth, popup.Height); 
        
                        } 
        
                    }

linear time-line

What is the best way to plot dates on a linear time-line? -e.g. Say I have 2 data points on Monday, none on Tues/Wed, and 3 on Thurs; I want the chart to group these in a way that's easy to see the dispersion of data over the week - now it just shows 5 evenly spaced points.
I could just add data; except my resolution is 1 second and the timescale could be months...

Prevent Toolwindow from resizing

I'm sure this must be simple, but I can't figure out how to do it.

When I resize a raddock with a toolwindow on the side, the toolwindow resizes proportionately along with the whole dock. I want to keep the toolwindow on the side the same size always, and allow the "slack" to be taken up by the other toolwindows.

I can't seem to find a MaximumSize property for the Toolwindow.

How do I do this?

RadGridView Filtering issue

I am experiencing some issues with allowing the user to filter data in the grid. We are using Telerik.WinControls.GridView, v8.2.0.0. In the designer, i have the following code:

this.grdAuditDetails.MasterGridViewTemplate.Columns.Add(gridViewTextBoxColumn1);

this.grdAuditDetails.MasterGridViewTemplate.Columns.Add(gridViewTextBoxColumn2);

this.grdAuditDetails.MasterGridViewTemplate.Columns.Add(gridViewTextBoxColumn3);

this.grdAuditDetails.MasterGridViewTemplate.Columns.Add(gridViewTextBoxColumn4);

this.grdAuditDetails.MasterGridViewTemplate.Columns.Add(gridViewTextBoxColumn5);

this.grdAuditDetails.MasterGridViewTemplate.Columns.Add(gridViewTextBoxColumn6);

this.grdAuditDetails.MasterGridViewTemplate.Columns.Add(gridViewTextBoxColumn7);

this.grdAuditDetails.EnableFiltering = true;

this.grdAuditDetails.MasterGridViewTemplate.EnableFiltering = true;

this.grdAuditDetails.MasterGridViewTemplate.EnableGrouping = false;

this.grdAuditDetails.MultiSelect = false;

this.grdAuditDetails.Name = "grdAuditDetails";

this.grdAuditDetails.ReadOnly = true;

this.grdAuditDetails.RightToLeft = System.Windows.Forms.RightToLeft.No;

//

this.grdAuditDetails.RootElement.ForeColor = System.Drawing.SystemColors.GradientActiveCaption;

this.grdAuditDetails.ShowGroupPanel = false;

this.grdAuditDetails.Size = new System.Drawing.Size(791, 590);

this.grdAuditDetails.TabIndex = 94;

this.grdAuditDetails.TabStop = false;

this.grdAuditDetails.Text = "radGridViewPreview";

this.grdAuditDetails.ThemeName = "Breeze";

((Telerik.WinControls.UI.

GridTableElement)(this.grdAuditDetails.GetChildAt(0))).CellSpacing = -1;

((Telerik.WinControls.UI.

GridTableElement)(this.grdAuditDetails.GetChildAt(0))).TableHeaderHeight = 26;

((Telerik.WinControls.UI.

GridTableElement)(this.grdAuditDetails.GetChildAt(0))).BorderColor = System.Drawing.Color.FromArgb(((int)(((byte)(255)))), ((int)(((byte)(255)))), ((int)(((byte)(246)))));

((Telerik.WinControls.UI.

GridTableElement)(this.grdAuditDetails.GetChildAt(0))).Padding = new System.Windows.Forms.Padding(3);

On the form, i can see the filter icons for the fields, but when the user speicifies how they want to filter and add their criteria, nothing happens. Can anyone please help me out with this issue?

Thanks!
