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,
