Hello,

I was wondering if anyone has any experience reloading a HostWindow.  I can get the HostWindows I need from my DockWindows, gather the info I need from it, close the the HostWindow, make my new calculations, create a new HostWindow and add it to the Dock.  However, this just puts the new HostWindow on the most recent document that had focus.  What I want is for the new HostWindow to show up/refresh in the same spot.  Does anyone know if this is possible?  

This is what I was thinking; but it leaves the old HostWindow in the Dock and does not seem to add the "new" HostWindow to the dock.
//set the current window to a host window, if not a host window will return null
HostWindow hw = this.dockMain.DockWindows[i] as HostWindow;
 
//creates new form in hostwindow
hw = new HostWindow(createRightForm(tempModel, formName));

If you need anymore info from me just let me know.  Thanks.

Hello Aditya,

The best solution in this case is just to replace the content of the current HostWindow:

//set the current window to a host window, if not a host window will return null
HostWindow hw = this.dockMain.DockWindows[i] as HostWindow;
Form form = createRightForm(tempModel, formName);
form.TopLevel = false;
form.FormBorderStyle = System.Windows.Forms.FormBorderStyle.None;
form.Dock = DockStyle.Fill;
hw.Controls.Clear();
hw.Controls.Add(form);

I hope this helps. Let me know if you need further assistance.

Hi Julian,

Thanks for the response.  However, I attempted your code but it seems to close the host window; I am not sure why.  Here is my code (I removed some of the commented out/old code): 

//re-run model
        private void miRunModel_Click(object sender, EventArgs e)
        {
            Cursor = Cursors.WaitCursor;
 
            int modelID = (int)currentNode.Value;
 
            Model tempModel = modelList.Where(d => d.modelID == modelID).FirstOrDefault();
             
            tempModel.getSignals();
 
            string selModelName = tempModel.modelName;
 
            //go through # of windows
            for (int i = 0; i < this.dockMain.DockWindows.Count; i++)
            {
                //set the current window to a host window, if not a host window will return null
                HostWindow hw = this.dockMain.DockWindows[i] as HostWindow;
                 
                if (hw != null)
                {
                    //split text of host window to get model and form type
                    string[] hwText = hw.Text.Split(':');
                    string modelName = hwText[0];
                    string formName = hwText[1].Trim();
 
                    //check if model names are the same
                    if (selModelName == modelName)
                    {
                        Form newForm = createRightForm(tempModel, formName);
 
                        newForm.TopLevel = false;
                        newForm.FormBorderStyle = System.Windows.Forms.FormBorderStyle.None;
                        newForm.Dock = DockStyle.Fill;
 
                        hw.Controls.Clear();
                        hw.Controls.Add(newForm);
                    }
                }
            }
            Cursor = Cursors.Arrow;
        }

Let me know if I am doing something wrong.  Thanks.

Hi Aditya,

The only missing code in this situation is Show() method of newly created Form:

private void miRunModel_Click(object sender, EventArgs e)
{
    Cursor = Cursors.WaitCursor;
 
    int modelID = (int)currentNode.Value;
 
    Model tempModel = modelList.Where(d => d.modelID == modelID).FirstOrDefault();
 
    tempModel.getSignals();
 
    string selModelName = tempModel.modelName;
 
    //go through # of windows
    for (int i = 0; i < this.dockMain.DockWindows.Count; i++)
    {
    //set the current window to a host window, if not a host window will return null
    HostWindow hw = this.dockMain.DockWindows[i] as HostWindow;
 
    if (hw != null)
    {
        //split text of host window to get model and form type
        string[] hwText = hw.Text.Split(':');
        string modelName = hwText[0];
        string formName = hwText[1].Trim();
 
        //check if model names are the same
        if (selModelName == modelName)
        {
        Form newForm = createRightForm(tempModel, formName);
 
        newForm.TopLevel = false;
        newForm.FormBorderStyle = System.Windows.Forms.FormBorderStyle.None;
        newForm.Dock = DockStyle.Fill;
 
        hw.Controls.Clear();
        hw.Controls.Add(newForm);
        newForm.Show();
        }
    }
    }
    Cursor = Cursors.Arrow;
}

If you continue to experience the same issue, please send me a sample project with your settings to investigate it locally. Please note that you have to open a new support ticket in order to be able to attach your files.

Thank you for your cooperation.
