Hi,

I reprduced the filter template for the date range in this demo:

Demo

It works, but I want to put this template in a UserControl because I have over 20 grid that will use this template.

But for some reason, the grid doesn't filter when my JS is inside my user control.

Could you please send me a sample project with an example? I am working with VS 2008 in VB,

Thanks.

Hello,

Please move this JS from Usercontrol to page.

Don't worry Its not an issue, But it is the general behavior of .net.

Note : When we used UpdatePanel/RadAJaxManager at that time USerControl's JS is not load in page.

Thanks,

Hi,

That's what I did. I put the JS outside the Usercontrol and inside the GridFilterTemplate which is in my PAGE as you can see in my GridColumn. If I move the JS outside the template, it can't cast the "Container" to GridItem. If I must move my JS outside the FilterTemplate, how can I get "ToPicker" and "FromPicker" ?

Thanks.

Hi Jocelyn,

Since you are using a GridDateTimeColumn, you could simply enable its range filtering to achieve the requested functionality instead of using a filter template:

<telerik:GridDateTimeColumn ... EnableRangeFiltering="true">

I hope this will prove helpful.

Hi,

the main reason why I was using a Template, this is because I wanted to have the second DatePicker on a new line. But I guess I will use EnableDateRangeFilter and try to add a "<br />" in code-behind.

Thanks for your help.

Edit: I ended up with this solution:

Private Sub gridCommuns_ItemDataBound(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridItemEventArgs) Handles gridCommuns.ItemDataBound

    If TypeOf e.Item Is GridFilteringItem Then

        Dim eItem As GridFilteringItem = DirectCast(e.Item, GridFilteringItem)

        Dim colDate As GridTableCell = eItem("colDernierRemp")



        SetDateRangeMessage(colDate)

    End If

End Sub

        Public Sub SetDateRangeMessage(ByVal col As GridTableCell)

            Dim fromLabel As LiteralControl = DirectCast(col.Controls(0), LiteralControl)

            Dim toLabel As LiteralControl = DirectCast(col.Controls(3), LiteralControl)

            fromLabel.Text = "<div class='alignLeft' style='width: 35px;'>" & GetMessageEx(1617).TexteHTML & ": " & "</div>"

            toLabel.Text = "<div class='spacer'></div><div class='alignLeft' style='width: 35px;'>" & GetMessageEx(1618).TexteHTML & ": " & "</div>"

        End Sub

Hello,

I tired my solution above and I have some bugs that I am unable to find a solution with the property "EnableRangeFilter".

1) If I set a date range like "From: 2012-12-18 To: 2012-12-18" I should get all date that have 2012-12-18 in the date column, but that's not what I get. I guess it check for the Time. If so, how can I ignore Time in the filter.

2) If I filter and after that I clear the two DatePicker and press enter, I want it to clear the filter, but nothing happens.

Thanks.

Hello Jocelyn,

1. Define the picker type:

<telerik:GridDateTimeColumn ... PickerType="DatePicker">

2. You can use the following approach:

protected void RadGrid1_ItemCreated(object sender, GridItemEventArgs e)

{

    if (e.Item is GridFilteringItem)

    {

        GridFilteringItem filterItem = e.Item as GridFilteringItem;

        RadDatePicker startPicker = filterItem["OrderDate"].Controls[1] as RadDatePicker;

        RadDatePicker endPicker = filterItem["OrderDate"].Controls[4] as RadDatePicker;

        string arguments = "dateInputKeyPressed(event,'" + startPicker.ClientID + "','" + endPicker.ClientID + "');";

        startPicker.DateInput.Attributes.Add("onkeypress", arguments);

        endPicker.DateInput.Attributes.Add("onkeypress", arguments);

    }

}

JavaScript:

function dateInputKeyPressed(event, startPickerID, endPickerID) {

    if (event.keyCode == 13) {

        if ($find(startPickerID).get_dateInput().get_textBoxValue() == "" &&

            $find(endPickerID).get_dateInput().get_textBoxValue() == "") {

            $find("<%=RadGrid1.ClientID%>").get_masterTableView().filter("OrderDate", "", "NoFilter");

        }

    }

}

I hope this helps. Please give it a try and let me know about the result.

All the best,
Eyup

Hi Eyup,

Yes it works, but I have a last issue that I can't solve. My column is bound to a field as a Date which contains a time like "#2012-04-21 05:24:32# but I have a "DateFormatString='{0:yyyy-MM-dd}' so it only shows the date without time. If i try to filter "From 2012-04-21 to 2012-04-21" it will not show the row with the date above because I guess it filter like this "From 2012-04-21 00:00:00 to 2012-04-21 00:00:00". How can I ignore the time in the filter?

Thanks.

Hello Jocelyn,

Please try enabling the following property:

<telerik:GridDateTimeColumn ... EnableTimeIndependentFiltering="true">

And let me know if it works for you.

Hi Eyup,

that's a simple solution. I don't know why I didn't see this property.

Thanks for your help!

Hi,

I am using the EnableRangeFiltering="true" but, for some strange reasons, I can't see the From: To: labels for either Datepicker. Any idea?

Many thanks

Hello Nuno,

This is strange, indeed. I am sending a sample RadGrid web site you can run to verify that they should be displayed as expected.
