RadFilterDropDownEditor problem

[Barbaros Saglamtimur]

Hi,

I found some samples about RadFilterDropDownEditor like:

public class RadFilterDropDownEditor : RadFilterDataFieldEditor
{
    protected override void CopySettings(RadFilterDataFieldEditor baseEditor)
    {
        base.CopySettings(baseEditor);
        var editor = baseEditor as RadFilterDropDownEditor;
        if (editor != null)
        {
            DataSourceID = editor.DataSourceID;
            DataTextField = editor.DataTextField;
            DataValueField = editor.DataValueField;
        }
    }

    public override System.Collections.ArrayList ExtractValues()
    {
        ArrayList list = new ArrayList();
        list.Add(_combo.SelectedValue);
        return list;
    }

    public override void InitializeEditor(System.Web.UI.Control container)
    {
        _combo = new RadComboBox();

        _combo.DataTextField = DataTextField;
        _combo.DataValueField = DataValueField;
        _combo.DataSourceID = DataSourceID;

        container.Controls.Add(_combo);
    }


    public override void SetEditorValues(System.Collections.ArrayList values)
    {
        if (values != null && values.Count > 0)
        {
            if (values[0] == null)
                return;
            var item = _combo.FindItemByValue(values[0].ToString());
            if (item != null)
                item.Selected = true;
        }
    }

    public string DataTextField
    {
        get
        {
            return (string)ViewState["DataTextField"] ?? string.Empty;
        }
        set
        {
            ViewState["DataTextField"] = value;
        }
    }
    public string DataValueField
    {
        get
        {
            return (string)ViewState["DataValueField"] ?? string.Empty;
        }
        set
        {
            ViewState["DataValueField"] = value;
        }
    }
    public string DataSourceID
    {
        get
        {
            return (string)ViewState["DataSourceID"] ?? string.Empty;
        }
        set
        {
            ViewState["DataSourceID"] = value;
        }
    }
    private RadComboBox _combo;
}

But I faced 2 problems.
1-When I try to set its DataType to System.Int32, I receive "Input string was not in a correct format." error. But when I set it to System.String it works. (the result is = '1' -within single quotas- as expected as it is set to be string). I have checked DataTextField and DataValueField properties and they are referencing to proper fields and datatypes.

2-When I set its value from combobox and add another condition/expression it looses it value and select first value of the combobox.

Any thoughts?

Thanks in advance.

Hello Barbaros,

I tried to replicate the issue which you described, but to no avail.
Attached to this message, you will find the code which I used for testing.

Please, take a look at it and let me know if there are any differences at your end, which I may be leaving out.

Best wishes,

Thanks for your reply. This is interesting: If I set DataSourceId property to an EntityDataSource I face problems as mentioned. But if I use DataSource property as in your example and use DataTable everything works as expected.

Hi,

Iam using VS2005 and .Net 2.0. I just wanted to know if the RadFilterDropDownEditor code is going to work. I tried to run but the drop down is not showing up. To make it run what I should be doing.

Thanks,
Raji
