How do I filter values of an Unbound WebCombo in a WebGrid?

Hello,

I made a workaround to get “DepartmentId” value that you might try.
I set the ComboMode to “MultipleColumns” and I add “DepartmentId” column to WebCombo as well.
In OnEnterEditMode client side event, I add a couple line of code the get the “DepartmentId” value.

Please kindly have review on the modified sample to see the result.

Thank you.

Hans.

Hi,

One problem with the code is eventually with different values it displays nothing which can be corrected by setting the values to display with style.display = "inline".

if (RowValue != WebComboValue)
{
	Row.RowElement.style.display = "none";
}
else
{
	Row.RowElement.style.display = "inline";
}

Now the next step is I want to filter based on the [Roles].[DepartmentId] column.

1. It probably needs to be added to the SqlDataSource2 SelectCommand.

<asp:SqlDataSource ID="SqlDataSource2" runat="server" ConnectionString="<%$ ConnectionStrings:SqlSampleConnection %>"
    SelectCommand="SELECT [RoleId], [RoleName], [DepartmentId] FROM [Roles]"></asp:SqlDataSource>

2. I do not want [Roles].[DepartmentId] to be displayed as a column in the DropDown

How do I reference the [Roles].[DepartmentId] Value in the OnEnterEditMode Event so I can Filter by it?

Thanks,

Doug

Hello,

I apologize for keep you waiting.

Basically, The SetAdditionalFilters() method can’t be used in Unbound WebCombo indeed. So it will make the issue occurs.

However, I have a workaround that you might try. I modified your validation code in OnEnterEditMode WebGrid’s client side event.
In that event, I try to get all rows in WebCombo result box and then I try to hide the row that doesn’t have the same value with WebCombo value.

Here’s the example snippet validation code:

function WebGrid1_OnEnterEditMode(controlId, TableName, editObject) {    var _WebGrid = ISGetObject(controlId);
    var _WebGridCell = editObject.ToCellObject();
    if (_WebGridCell.Name == "Roles") {
        var _WebCombo = editObject.element;
                
        //So I can get WebCombo rows
        _WebCombo.ShowDropDown(); 
                
        window.setTimeout(function () {
            //To get WebCombo value
            var WebComboValue = _WebCombo.Values[0].Value; 
            //To get WebCombo rows
            var WebComboRows = _WebCombo.GetRows();
            var RowsLength = WebComboRows.length;
                    
            for (i = 0; i < RowsLength; i++) {
                var Row = WebComboRows[i];
                var RowValue = Row.Value;
                        
                if (RowValue != WebComboValue)
                    Row.RowElement.style.display = "none";
            }
            //To hide the dropdown again
            _WebCombo.HideDropDown();
        }, 500);
    }
    return true;
}

I attached the modified sample as well. Hope this helps.
Thank you.

Regards,
Hans.

Hello,

Is your server still having problems? (Other people are getting responses.)

Since you already replied about server problems, does that mean I dropped out of your To Do queue?

Have you done any investigation prior to this reply?

Please respond.

Thanks,

Doug

Hi,

I replied to a posting that was answered and could not figure out how to un-answer it to make sure Support would look at it so I created this post. Please refer to:

http://www.intersoftpt.com/Community/WebGrid/How-do-I-set-multiple-values-for-an-Unbound-WebCombo-in-a-WebGrid-to-show-up-in-the-DropDown/

How do I filter the List Items in the Unbound WebCombo?

I tried to use the WebCombo Client Side Method SetAdditionalFilters in the WebGrid ClientSideEvent OnEnterEditMode based on a value in the row but on the first time a row

is selected it does not filter and on subsequent rows selected nothing is in the Drop Down List.

I modified the code Hans supplied with:

<ClientSideEvents
	OnEnterEditMode="WebGrid1_OnEnterEditMode"
/>

<script language="javascript" type="text/javascript">

	function WebGrid1_OnEnterEditMode(controlId, TableName, editObject)
	{
		var _WebGrid = ISGetObject(controlId);
		var _WebGridCell = editObject.ToCellObject();
		if (_WebGridCell.Name == "Roles")
		{
			var _WebCombo = editObject.element;
			var FilterValue_String ;
			var EmployeeID_String = _WebGridCell.Row.GetCell("EmployeeID").Value
			if (true)
			{
				switch (EmployeeID_String)
				{
					case "1":
						FilterValue_String = "1";
						break;
					default:
						FilterValue_String = "2";
				} 
				_WebCombo.SetAdditionalFilters("[RoleId] = " + FilterValue_String);
			}
			else
			{
				switch (EmployeeID_String)
				{
					case "1":
						FilterValue_String = "Research Staff";
						break;
					default:
						FilterValue_String = "Research Manager";
				}
				_WebCombo.SetAdditionalFilters("[RoleName] = " + "'" + FilterValue_String + "'");
			}
			_WebCombo.SetText(_WebGridCell.Text, true);
		}
		return true;
	}

</script>

Please see attached screenshots and code.

Thanks,

Doug
