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.

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?

setting 100% height for MultipleExpandedItems expandmode

is it possible to set 100% height on the panelbar for MultipleExpandedItems. I want a UI style in which i have a panelbar occupying 100% height with multipleexpandeditems mode. There can be 2-3 panelitems inside that and inside each panelitem there would be a treeview control which should also occupy 100% height of that panelitem. In such a way that scrollbars of treeview are visible and not of the panelitem. I tried but somehow 100% was not working. Is this a known limitation or any workarounds exists?

Modifying ButtonSprites.gif -- Right Side of Button?

Hi!

We customized the button by modifying the ButtonSprites file with the below CSS. Everything seems to work for the most part, but we can't seem to get access to the image at the right. CustomizedSearchButton.PNG shows the result of the CSS change (using the file ButtonSprites.png as the background.) We did attempt to see where the button is pulling from in the file ButtonSprites2.png -- however, it appears that the right side of the button does not use any part of this file. We did skin the app with the Windows 7 theme, but we want to override the background image.

Is this possible? Where is it pulling the right side of the button from?

Thanks!
Michael

Setting Localization in Config File

Hi,

we evaluate the use of the RadEditor in our SharePoint-Site. How can I set the localization to German? I've seen many code snippets how to set the language in aspx-files, and tried to mimic this in the config files, but adding the following line to the ListConfigFile and the ConfigFile did not have the indended result:

<property name="Language">de-DE</property><BR>

Is there another way for setting the localization?

Thanks for your help.

Problem with client configuration

Hi. I am currently using the following version of the Telerik Asp.Net Ajax Controls.
Latest Version: 2008.1 619 (Jun 19, 2008)

We have developed a site for a number of customers, which has been running with no problems that we are aware of. Our largest customer has decided to opt in to an extra feature of the site which was developed with Ajax and the Ajax tools, and are not having any luck.

They are a large financial institution and all of their web access is through IBM's Tivoli Access Manager and WebSEAL.

We have ascertained that if they access the site directly and do not go through WebSEAL, the site will run fine. We are struggling to assist because we do not have any environment to replicate this, and we cannot replicate the error.

I am hoping that perhaps someone in Telerik or another client will have had an issue similar to this in the past and may be able to offer assistance either for something we could change in our code, or they could change in Tivoli, which would enable the Telerik controls to work ok.

The specific error they are encoutering is as follows (I have had to doctor some information out).

column header and row data wraps while hiding column from Header Context Menu

Hi,

For many grids in our project, there are around 40 columns, so we were trying to use the gridpersister to save the settings for individual user, so that the user can customize the number of columns they want to see everytime.
Saving and loading grid setting works fine. The problem is when the user tries to hide thie column from the header contextmenu, the arrangement of the columns are lost. I have used wrap="false" for Column header and Item properties in the gid. After hiding 1 or 2 column, most of the headers and coluns are wrapped.
The problem is very prominent in IE7, almost all the columns and all the row data are wrapped. I am using the following code for columns. I cannot use fixed width header as my coulmn values vary from 40 to 400 characters and I don't want white space in the column.

<HeaderStyle VerticalAlign="Bottom" HorizontalAlign="Left" />

<ItemStyle Wrap="False" VerticalAlign="Top" HorizontalAlign="Left"/>

Please suggest what to do.
