Automatic URL Encoding?

[Augusto]

Hello,

I have a lot of Grids that display correctly strings from a database that contains Chinese and Japanese characters as well as German and French accents. I have to build links from this items in the Grids to display the details in another page.

The URL passed to the new page has the Chinese/Japanese/etc characters: http://test.aspx?Os=Microsoft Windows 7 旗舰版

Because the way IE works I need this URL to be encoded or when I read back the Os variable it will return the value Microsoft Windows 7 ????.

I know I can accomplish this via the following Sub:

Protected Sub MyGrid_ItemDataBound(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridItemEventArgs) Handles MyGrid.ItemDataBound
        If e.Item.ItemType = GridItemType.Item Or e.Item.ItemType = GridItemType.AlternatingItem Then
            Dim dataItem As GridDataItem = CType(e.Item, GridDataItem)
            Dim currentRow As DataRowView = DirectCast(e.Item.DataItem, DataRowView)
            For Each col As GridColumn In RadgridWinServerOSCount.Columns
                If col.UniqueName = "columnOS" Then
                    Dim strTxt As String = currentRow.Row("Operating_System").ToString
                    Dim NewUrl As String
                    NewUrl = Server.UrlEncode(strTxt)
                    CType(dataItem("columnOS").Controls(0), HyperLink).NavigateUrl = "~/test.aspx?Os=" & NewUrl
                End If
            Next
        End If
    End Sub

However this is kind of unpractical as the application I'm handling have around 25 different Grids where this needs to be changed, hence, even by creating a function to re-write the URL it's going to require a lot of code and the maintenance would be too cumbersome.

I was wondering if there's a way to "automatically" URL encode the GridHyperLinkColumn items in the Grid, I looked throught the documentation but I couldn't find anything relevant. I think to optionally allow this encoding for GridHyperLinkColumn would be really handy.

Thanks!

Hi Augusto,

Such a feature is not available in the hyperlink column of RadGrid and I am afraid the code-behind solution is the only one available.

Thanks Tsvetoslav,

I suspected that. Will it be possible for you guys to consider adding a feature for RadGrid to enable URL encoding as an option? It will be a great addition for those people that need Japanese, Chinese, Cirilyc language sets and use IE.

Thanks,

Augusto.

Hi Augusto,

Unfortunately, for the time being our development team has deemed it not necessary to implement such a feature. However, if more customers express an interest in it we will give it due consideration.

You can also try inheriting from the GridHyperlinkColumn

I'm trying something along these lines. Haven't started testing yet, so we'll see how it goes...

public class GridEncodableHyperlinkColumn : GridHyperLinkColumn {

        public bool URLEncodeLinks { get; set; }

        public GridEncodableHyperlinkColumn() : base() {
            URLEncodeLinks = true;
        }

        protected override string FormatDataNavigateUrlValue(object[] dataUrlValues) {
            if (URLEncodeLinks) {
                for (int i = 0; i < dataUrlValues.Length; i++ ) {
                    if (dataUrlValues[i] != null && dataUrlValues[i] is string && !string.IsNullOrEmpty((string)dataUrlValues[i])) {
                        string dataUrlValue = HttpContext.Current.Server.UrlEncode((string)dataUrlValues[i]);
                        dataUrlValues[i] = dataUrlValue;

                    }
                }
            }

            return base.FormatDataNavigateUrlValue(dataUrlValues);
        }
    }

...then just use that instead of the GridHyperLinkColumn.

Hi, is it still the case that in the latest version of the GridHyperLinkColumn it does not URL encode the DataNavigateUrlFields, so I have to do this myself manually eg in code behind?

If so, please consider adding this capability as it is rather clumsy to do manually when the whole point of the DataNavigateUrlFields and DataNavigateUrlFormatString properties is for the control config to be 100% declarative.

Thanks
