[Solved] Document Manager and Filenames with non-printable characters

Hi,

Today we had an interesting problem that I'm hoping you'll be able to help me fix.

One of our clients, using the Rad Editor (ASP.NET), clicked on the Document Manager and the listing displayed no files.

However the folder that was being accessed had 77 files.

Upon trying to find out why they weren't being displayed, I discovered that one of the file names had a non-printable character in it.

So, once I renamed the file the listing of files worked fine.

The question is:
How do I fix the filenames of files being uploaded so that files are not stored on our servers that may contain non-printable characters?
And
Even if they do contain non-printable characters, how do I get the Document Manager to display the folder of files anyway (with or without the offending file)?

Thanks,
Cameron

Bind control when filtering

So using the RadControl, I think I managed to get it to filter the datetime correctly so it can only do Dates even when times are included in the data source.This is calling the OnItemCommand event for the control.
But, when I do a datasource and a bind(), no results are shown even though the data does exist in the datasource

The control does filtering based on AJAX Requests I believe so how can I follow this convention?
At the end of the day, The data in this scenario is being filtered on the server end and wish to rebind this.

or alternatively, can someone tell me how I can do the date filtering on clientside using the GridDateTimeColumn, so I can obtain the FilterType and the current selected date then finally do a filter?

Thanks

GridBoundColumn DateTime javascript error on between filter.

I am attempting to apply a date range filter to a GridBoundColumn bound to a DateTime.

<telerik:GridBoundColumn DataField="Created" FilterControlAltText="Filter Created column"

HeaderText="Created" SortExpression="Created" UniqueName="Created">

<FilterTemplate>

<telerik:RadDatePicker ID="ToCreatedDatePicker" runat="server" Width="85px"

MinDate="01-01-2012" DbSelectedDate='<%# EndCreatedDate %>' ClientEvents-OnDateSelected="ToDateSelected"/>

to

<telerik:RadDatePicker ID="FromCreatedDatePicker" runat="server" Width="85px"

MinDate="01-01-2000" DbSelectedDate='<%# StartCreatedDate %>' ClientEvents-OnDateSelected="FromDateSelected"/>

<telerik:RadScriptBlock ID="scriptFilterEventDate" runat="server">

<script type="text/javascript">

function FromDateSelected(sender, args) {

var tableView = $find("<%# ((GridItem)Container).OwnerTableView.ClientID %>");

var ToPicker = $find('<%# ((GridItem)Container).FindControl("ToCreatedDatePicker").ClientID %>');

var fromDate = FormatSelectedDate(sender);

var toDate = FormatSelectedDate(ToPicker);

if (toDate != '') {

tableView.filter("Created", fromDate + " " + toDate, "Between");

}

function ToDateSelected(sender, args) {

var tableView = $find("<%# ((GridItem)Container).OwnerTableView.ClientID %>");

var FromPicker = $find('<%# ((GridItem)Container).FindControl("FromCreatedDatePicker").ClientID %>');

var fromDate = FormatSelectedDate(FromPicker);

var toDate = FormatSelectedDate(sender);

if (fromDate != '') {

tableView.filter("Created", fromDate + " " + toDate, "Between");

}

function FormatSelectedDate(picker) {

var date = picker.get_selectedDate();

var dateInput = picker.get_dateInput();

var formattedDate = dateInput.get_dateFormatInfo().FormatDate(date, dateInput.get_displayDateFormat());

return formattedDate;

}

</script>

</telerik:RadScriptBlock>

</FilterTemplate>

</telerik:GridBoundColumn>

When the filter is applied I receive the following error message from javascript console.

Uncaught Sys.WebForms.PageRequestManagerServerErrorException: Sys.WebForms.PageRequestManagerServerErrorException: String was not recognized as a valid DateTime.

Sys.WebForms.PageRequestManager._endPostBackTelerik.Web.UI.WebResource.axd:15

Sys.Net.WebRequest.completedTelerik.Web.UI.WebResource.axd:6

_onReadyStateChange

The filter is not applied when this error is received

Any idea what I'm doing wrong here..

Filtering between dates

Hi.
Following some examples, I found this:

http://www.telerik.com/community/code-library/aspnet-ajax/general/filtering-range-with-raddatepicker-instances-in-a-custom-filtering-column.aspx

I am trying to filter a data source between 2 selected dates.

I am almost there with the implementation of the solution however the problem is, even when the dates are selected, the SelectedDate on the ItemCommand event is null (Nothing in VB.NET)

any ideas where I have gone wrong?

<telerik:GridTemplateColumn HeaderStyle-HorizontalAlign="Center"

HeaderText="DateFilter" SortExpression="DateTime" UniqueName="DateFilter"

AllowFiltering="true" ShowFilterIcon="true" AutoPostBackOnFilter="false" DataType="System.DateTime"

DataField="DateTime" ItemStyle-HorizontalAlign="Left">

<HeaderStyle Width="90px"></HeaderStyle>

<ItemStyle HorizontalAlign="Left" Width="90px"></ItemStyle>

<FilterTemplate>

<telerik:RadComboBox ID="ddlDateFilter" runat="server" DropDownWidth="200px">

<Items>

<telerik:RadComboBoxItem Text="" Selected="true" />

</Items>

<ItemTemplate>

From <telerik:RadDatePicker ID="RadDatePickerFrom" runat="server" onclick="PreventDropDownClose(event);">

</telerik:RadDatePicker>

To <telerik:RadDatePicker ID="RadDatePickerTo" runat="server" onclick="PreventDropDownClose(event);">

</telerik:RadDatePicker>

<asp:Button ID="cmdFilterDates" runat="server" Text="Filter" CommandName="FilterDates" />

</ItemTemplate>

</telerik:RadComboBox>

</FilterTemplate>

</telerik:GridTemplateColumn>

Code:

Protected Sub grdShiftObservation_OnItemCommand(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridCommandEventArgs) Handles grdShiftObservation.ItemCommand

If String.Equals(e.CommandName, "filterdates", StringComparison.OrdinalIgnoreCase) Then

Dim cell As TableCell = CType(e.Item, Telerik.Web.UI.GridFilteringItem)("DateFilter")

Dim dateFilterComboBox As RadComboBox = CType(cell.Controls(0).FindControl("ddlDateFilter"), RadComboBox)

Dim dateFrom As RadDatePicker = CType(dateFilterComboBox.SelectedItem.FindControl("RadDatePickerFrom"), RadDatePicker)

Dim dateTo As RadDatePicker = CType(dateFilterComboBox.SelectedItem.FindControl("RadDatePickerTo"), RadDatePicker)

End If

End Sub

dateFrom and dateTo show "Nothing"

any ideas? I want to be able to obtain the dates the user has selected.

Find FilterCriteria clientside

Hi.
using RadControls I believe - how can I get the filter type chosen by the user on clientside, so I can do a filter based upon that.
We hit a problem with date filtering so if we do an Equals, it will not find the date since the time is not considered when performing the filtering.

Example:

telerik:GridDateTimeColumn FilterControlWidth="60px" AllowFiltering="true" AutoPostBackOnFilter="false"

CurrentFilterFunction="Contains" HeaderStyle-HorizontalAlign="Center" DataField="DateTime"

HeaderText="Date" SortExpression="DateTime" ShowFilterIcon="true" UniqueName="DateTime"

PickerType="DatePicker" DataFormatString="{0:g}" DataType="System.DateTime">

<HeaderStyle Width="100px" HorizontalAlign="center"></HeaderStyle>

<ItemStyle HorizontalAlign="center" Width="100px"></ItemStyle>

</telerik:GridDateTimeColumn>

So we have the datetimes showing.
But at this point, how can I intercept the filtering on the clientside, so I can then also get the input they have entered to filter textbox/datepicker then append say "00:00:00" to that value, finally doing the filter.

how can I do this?

Grid does not show results when binding

Using RadControls I believe.
We have a DateTimePicker and need to do custom filtering on Date only.
I have implemented the code on the ItemCommand event and then I filter a dataset and then finally set the datasource to the grid and bind. I know there are results in there but the grid shows "no results"

any ideas?

<telerik:GridDateTimeColumn FilterControlWidth="60px" AllowFiltering="true" AutoPostBackOnFilter="false"

CurrentFilterFunction="Contains" HeaderStyle-HorizontalAlign="Center" DataField="DateTime"

HeaderText="Date" SortExpression="DateTime" ShowFilterIcon="true" UniqueName="DateTime"

PickerType="DatePicker" DataFormatString="{0:g}" DataType="System.DateTime">

<HeaderStyle Width="100px" HorizontalAlign="center"></HeaderStyle>

<ItemStyle HorizontalAlign="center" Width="100px"></ItemStyle>

</telerik:GridDateTimeColumn>

Code:

Protected Sub grdShiftObservation_OnItemCommand(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridCommandEventArgs) Handles grdShiftObservation.ItemCommand

If e.CommandName = RadGrid.FilterCommandName Then

Dim filterPair As Pair = DirectCast(e.CommandArgument, Pair)

Select Case filterPair.Second.ToString()

Case "DateTime"

Dim filterOption As String = CType(e.CommandArgument, Pair).First

Dim filterItem As GridFilteringItem = CType(e.Item, GridFilteringItem)

Dim currentPattern As String = CType(filterItem(CType(e.CommandArgument, Pair).Second).Controls(0), RadDatePicker).SelectedDate

If Not String.IsNullOrEmpty(currentPattern) Then

Dim dt As DateTime = Convert.ToDateTime(currentPattern)

Dim dtFromString As String = dt.ToString("MM/dd/yyyy") & " 00:00:00" ' i.e the date they selected in the picker

Dim dtToString As String = dt.AddDays(1).ToString("MM/dd/yyyy") & " 00:00:00"

Dim filterPatternAssist As String = String.Empty

Dim dateColumn As GridBoundColumn = CType(e.Item.OwnerTableView.GetColumnSafe("DateTime"), GridBoundColumn)

Select Case filterOption

Case "EqualTo"

dtFromString = "DateTime >= #" & dtFromString & "# AND DateTime < #" & dtToString & "#"

dateColumn.CurrentFilterFunction = GridKnownFunction.EqualTo

Case "NotEqualTo"

dtFromString = "Not DateTime = #" & dtFromString & "#"

dateColumn.CurrentFilterFunction = GridKnownFunction.NotEqualTo

Case "GreaterThan"

dtFromString = "DateTime > #" & dtFromString & "#"

dateColumn.CurrentFilterFunction = GridKnownFunction.GreaterThan

Case "LessThan"

dtFromString = "DateTime < #" & dtFromString & "#"

dateColumn.CurrentFilterFunction = GridKnownFunction.LessThan

Case "GreaterThanOrEqualTo"

dtFromString = "DateTime >= #" & dtFromString & "#"

dateColumn.CurrentFilterFunction = GridKnownFunction.GreaterThanOrEqualTo

Case "LessThanOrEqualTo"

dtFromString = "DateTime <= #" & dtFromString & "#"

dateColumn.CurrentFilterFunction = GridKnownFunction.LessThanOrEqualTo

Case "Between"

dtFromString = "#" & dtFromString & "' <= DateTime AND DateTime <= #" & filterPatternAssist & "#"

dateColumn.CurrentFilterFunction = GridKnownFunction.Between

Case "NoFilter"

dtFromString = String.Empty

dateColumn.CurrentFilterFunction = GridKnownFunction.NoFilter

Case "NotBetween"

dtFromString = "DateTime <= #" & dtFromString & "' OR DateTime >= #" & filterPatternAssist & "#"

dateColumn.CurrentFilterFunction = GridKnownFunction.NotBetween

Case "IsNull"

Case "NotIsNull"

Case "Contains"

dtFromString = String.Empty

dateColumn.CurrentFilterFunction = GridKnownFunction.NoFilter

End Select

FilterGrid(dtFromString)

End If

End Select

End If

End Sub

Private Sub FilterGrid(ByVal strFilter As String)

Dim ds As DataSet = GetData()

Dim dvFilter As DataView = ds.Tables(0).DefaultView

dvFilter.RowFilter = strFilter

grdShiftObservation.DataSource = dvFilter.ToTable()

grdShiftObservation.DataBind()

End Sub

I know dvFilter.ToTable() at this point shows me say 5 rows filtered but when the grid is displayed, it shows no results.

what am I doing wrong? How else can I show the filtered results? I am trying to fix lack of support on the control which does not filter datetime values with date only specified hence the customisation above.

[Solved] Any alternatives to resizing height of grid client size?

I've implemented the solution described here already: http://www.telerik.com/help/aspnet-ajax/grid-resizing-in-splitter.html.

However there are a number of drawbacks. Are there any other options for implementing a resizable RadGrid?
