[Solved] Click on column header

[Gerard Kerbourch]

Hi,

How to detect header column click event ?

I  couldn't find the appropriate event in grid properties...

In order to do that, I've put a label in each column header, and handle MouseLeftButtonUp event.
But of course it is not a good solution.

Does someone have better solution/idea ?

Thanks

Hi Gerard ,

You may use the following approach :

using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Animation;
using System.Windows.Shapes;
using Telerik.Windows.Controls.GridView;
using Telerik.Windows.Controls;

namespace StarColumnProblem
{
    public partial class MainPage : UserControl
    {
        public MainPage()
        {
            InitializeComponent();
            this.AddHandler(GridViewHeaderCell.MouseLeftButtonDownEvent, new MouseButtonEventHandler(MouseDownOnHeaderCell), true);
        }

        private void MouseDownOnHeaderCell(object sender, MouseEventArgs args)
        {
            GridViewHeaderCell cellClicked = ((FrameworkElement)args.OriginalSource).ParentOfType<GridViewHeaderCell>();

            if (cellClicked == null)
                return;

            MessageBox.Show(cellClicked.Column.UniqueName);
        }
    }

I am late, but thank you for response, it's ok now.

I have another problem with the GridView.

I want to get the double click on a line, but when I click at least 2 times in a row, I get an error that I can not control.
The GridView is loaded by this method:

It seems that the problem just because I do not meet property 'path' in the binding. But I can't find a solution, except perhaps the one below, but I did not understand ... :

Thank you for your help

Hi Gerard,

You can try my DataTable instead.

All the best,

New question...

how to convert in vb.net this code (data.cs class) :

 foreach (var row in this.Rows)
                {
                    var item = Activator.CreateInstance(type);
                    propertyInfos.ForEach(p => p.SetValue(item, row[p.Name], null));

                    list.Add(item);
                }

thanks

I already tried but it's not good, the results :

For Each row As var In Me.Rows
    Dim item As var = Activator.CreateInstance(type)
    propertyInfos.ForEach(Function(p As ) p.SetValue(item, row(p.Name), Nothing))

    list.Add(item)
Next

Finally, I managed to translate. My translation simplified :

                    Dim p As System.Reflection.PropertyInfo
                    For Each p In propertyInfos
                        If row.ContainsKey(p.Name) Then
                            p.SetValue(item, row(p.Name), Nothing)
                        End If
                    Next

Thanks
