Cannot bind to KeyValueConfigurationCollection

[Ricky]

Hi, I try to bind a gridview to an instance of KeyValueConfigurationCollection as follows:

private void WebHRSnifferForm_Load(object sender, EventArgs e)
        {
            dataBind104ComSettingGrid();

        }
        private void dataBind104ComSettingGrid()
        {
            // QueryStringParams is type of KeyValueConfigurationCollection
            Grid104CompSetting.DataSource = webHRConfig.OneZeroFour.Company.QueryStringParams.GetEnumerator();
        }

But it seems the girdview cannot locate the properties exposed by KeyValueConfigurationElement that is contained within KeyValueConfigurationCollection. So no columns are created.

Is there anything I should implement to let gridview bind to KeyValueConfigurationCollection.

Thanks a lot.
Ricky.

Hello Ricky,

Thank you for writing.

The RadGridView currently does not support Hashtable types of collections like the KeyValueConfigurationCollection.

You can use this workaround for the time being:

private BindingList<KeyValueElement> confList;
private KeyValueConfigurationCollection config;

private void Form3_Load(object sender, EventArgs e)
{
    config = new KeyValueConfigurationCollection();
    config.Add("TestKey1", "TestValue1");
    config.Add("TestKey2", "TestValue2");
    config.Add("TestKey3", "TestValue3");
    config.Add("TestKey4", "TestValue4");
    config.Add("TestKey5", "TestValue5");
    config.Add("TestKey6", "TestValue6");
    config.Add("TestKey7", "TestValue7");

    confList = new BindingList<KeyValueElement>();
    foreach(KeyValueConfigurationElement elem in config)
    {
        confList.Add(new KeyValueElement(elem.Key, elem.Value));
    }

    radGridView1.DataSource = confList;

    //make changes to collection............
    config.Clear();
    foreach(KeyValueElement elem in confList)
    {
        config.Add(new KeyValueConfigurationElement(elem.Key,elem.Value));
    }
}

public class KeyValueElement
{
    private string key;
    private string val;

    public KeyValueElement()
    {
        this.key = "";
        this.val = "";
    }

    public KeyValueElement(string key, string value)
    {
        this.key = key;
        this.val = value;
    }

    public string Value
    {
      get { return val; }
      set { val = value; }
    }

    public string Key
    {
        get { return key; }
        set { key = value; }
    }
}

I hope this helps. Please contact us again if we could be of any additional service.

All the best,
