I know this topic has been brought up before, but I believe it is one of the most important features that should be included in the next release of RadControls for WinForms. Will Aero glass ever be incorporated into Telerik's RadRibbon? Other ribbon vendors have achieved this already... I think at least Telerik could figure out how they do it and provide it to us :) Are there any setbacks or challenges preventing you from implementing this feautre? I would love this so much, and anything you could do to make this happen would be amazing!

Thanks,

Multiple fields as DisplayMember

Hi everyone,

Is there a way to show more than one field? As far as I can tell 'DisplayMember' only allows one field, but I'd like to display multiple.

I made the same application with RadTree in WebForm and there I could easily change the text in the 'NodeBound' event. I didn't find this in WinForm.

Thanks
Thomas

Picture Stretch

We have our grid working very nicely now. Just one issue I need to work through.

Is there any way to stop a picture stretching out of proportion? I need to allow the picture to grow if column and row size is increased but keep the proportions.

Any help much appreciated.

Crash when add new row

Hi!,

Have a very simple example, binding custom collection to grid. And have a button, in event handler of it "bindingsource.AddNew();". Problem is when you sort grid, then try to add new row, I got "Object reference not set to an instance of an object." exception.

Here is the code, it is very simple:

    
            public partial class Form1 : Form  
        
                {  
        
                    public Form1()  
        
                    {  
        
                        InitializeComponent();  
        
                    }  
        
                    private void Form1_Load(object sender, EventArgs e)  
        
                    {  
        
                        InitEmployeeGrid();  
        
                        InitActions();  
        
                        BindData();  
        
                    }  
        
                    private void InitEmployeeGrid()  
        
                    {  
        
                        gridView.MasterGridViewTemplate.AllowAddNewRow = false;  
        
                        gridView.MasterGridViewTemplate.AutoGenerateColumns = false;  
        
                        GridViewTextBoxColumn nameColumn = new GridViewTextBoxColumn();  
        
                        nameColumn.FieldName = "Name";  
        
                        nameColumn.HeaderText = "Name";  
        
                        nameColumn.UniqueName = "nameColumn";  
        
                        gridView.Columns.Add(nameColumn);  
        
                    }  
        
                    public void InitActions()  
        
                    {  
        
                        addToolbarButton.Click += new EventHandler(addToolbarButton_Click);  
        
                        cancelToolbarButton.Click += new EventHandler(cancelToolbarButton_Click);  
        
                    }  
        
                    void cancelToolbarButton_Click(object sender, EventArgs e)  
        
                    {  
        
                        if (gridView.DataSource != null)  
        
                        {  
        
                            (gridView.DataSource as BindingSource).CancelEdit();  
        
                            gridView.CancelEdit();  
        
                        }  
        
                    }  
        
                    void addToolbarButton_Click(object sender, EventArgs e)  
        
                    {  
        
                        if (gridView.DataSource != null)  
        
                        {  
        
                            (gridView.DataSource as BindingSource).AddNew();  
        
                            gridView.BeginEdit();  
        
                        }  
        
                    }  
        
                    private void BindData()  
        
                    {  
        
                        employeeBindingSource.DataSource = CreateDataSource();  
        
                        gridView.DataSource = employeeBindingSource;  
        
                    }  
        
                    private object CreateDataSource()  
        
                    {  
        
                        List<Employee> result = new List<Employee>();  
        
                        result.Add(new Employee("Georg"));  
        
                        result.Add(new Employee("Mike"));  
        
                        result.Add(new Employee("Timothy"));  
        
                        return result;  
        
                    }  
        
                }

Can anybody help me with this ? Thanks.

[Solved] Getting xml from GridView datasource

Hi there,

I'm trying to generate xml from the datasource of rad gridview. Following is how I'm binding data to the grid:

radgvParticulars.MasterGridViewTemplate.DataSource = dsTODetails.Tables[1];

I'm wrote the following code to extract the xml from the datasource:

DataSet ds = (DataSet)radgvParticulars.DataSource;
string strXml = ds.GetXml();

This throws an InvalidCastException - "Unable to cast DataTable object to DataSet object". Then I tried the same by writing the below code:

DataTable dt = new DataTable();
dt = (DataTable)radgvParticulars.DataSource;
DataSet dsnew = new DataSet();
dsnew.Tables.Add(dt);
string strXml = dsnew.GetXml();

But this throws another exception: "DataTable already belongs to another DataSet".

I'm unable to proceed further. Pls help.

Regards,
Pramod Goutham.
