Hi,

I am using a grid with a button that opens a modal popup window. When I click the button the grid is overlayed, but not the entire screen - just the grid. Then when the popup opens the rest of the screen is overlayed.
How can I control the first overlay and make it overlay the entire screen, directly when the user clicks on the button?

Excerpt from my page:

 <telerik:GridEditCommandColumn UniqueName="actionsCommandColumn" EditText="Go" ButtonType="PushButton" HeaderStyle-CssClass="RadGridHeaderStyle">
                          <HeaderStyle Font-Bold="True" Width="9%" />
                        </telerik:GridEditCommandColumn>
                    </Columns>
                    <EditFormSettings EditFormType="WebUserControl" PopUpSettings-Modal="true" UserControlName="CustomControls\QuoteAndPolicyActions.ascx"
                        CaptionFormatString="Select an Action">
                        <EditColumn UniqueName="EditCommandColumn1" FilterControlAltText="Filter EditCommandColumn column"
                            Visible="false">
                        </EditColumn>
                    </EditFormSettings>

Thanks for your help,
Nicolas

Hierarchical grid and stored procedures

I am currently looking at the following demo,

http://demos.telerik.com/aspnet-ajax/grid/examples/programming/hierarchy/defaultvb.aspx

Which show how to build a hierarchial grid programmaticaly. The problem I have is that I wish to use a datatable populated from a stored procedure for the grids. I have tried the following,

Private Sub Page_Init(ByVal sender As Object, ByVal e As EventArgs) Handles MyBase.Init

buildGrid()

End Sub

Sub buildGrid()

Dim state As String = drp_state.SelectedValue

If state = "" Then

state = 0

End If

Dim dt As DataTable = myDataAccessClass.data1(param1, param2)

Datasource = dt

GridDataKeyNames = "ID"

' masterTableCreation builds and adds the columns, no issue with this.

masterTableCreation()

Dim dtSub As DataTable = myDataAccessClass.data1(param3)

hierarchyTable(dtSub, "", "ID", "ID")

End Sub

Public Sub hierarchyTable(ByVal dt As DataTable, ByVal datakeys As String, ByVal masterKeyField As String, ByVal detailKeyField As String)

Dim hierarchyTable As New GridTableView(RadGrid1)

' set the datasouce

hierarchyTable.DataSource = dt

hierarchyTable.Width = Unit.Percentage(100)

Dim datakeysArray() As String

If datakeys <> "" Then

datakeysArray = datakeys.Split(",".ToArray())

hierarchyTable.DataKeyNames = datakeysArray

End If

Dim relationFields As GridRelationFields = New GridRelationFields()

relationFields.MasterKeyField = masterKeyField

relationFields.DetailKeyField = detailKeyField

hierarchyTable.ParentTableRelation.Add(relationFields)

RadGrid1.MasterTableView.DetailTables.Add(hierarchyTable)

'add columns

Dim boundColumn As GridBoundColumn

hierarchyTable.Columns.Clear()

For i As Int32 = 0 To Datasource.Columns.Count - 1

Dim column As DataColumn = Datasource.Columns(i)

Dim colDataType As String = column.DataType.ToString().ToLower().Replace("system.", "")

boundColumn = New GridBoundColumn

hierarchyTable.Columns.Add(boundColumn)

boundColumn.DataField = column.ColumnName

boundColumn.HeaderText = column.ColumnName.Replace("_", " ").ToLower()

boundColumn.DataFormatString = "<nobr>{0}</nobr>"

boundColumn.ItemStyle.HorizontalAlign = HorizontalAlign.Left

Next

End Sub

<telerik:RadGrid ID="RadGrid1" runat="server" AutoGenerateColumns="False" AllowSorting="True" AllowPaging="True" PageSize="5" GridLines="None" ShowGroupPanel="True">

<MasterTableView AllowMultiColumnSorting="True" GroupLoadMode="Server">

</MasterTableView>

<PagerStyle Mode="NextPrevNumericAndAdvanced"></PagerStyle>

<ClientSettings AllowDragToGroup="true" />

</telerik:RadGrid>

The grid will expand to show the child table, however with no data. Any pointers would be much appreciated.

Filtering in Hierarchy Question.

Hello,

I have a quick question. I would like to know if it is possible to implement Column Filtering for Hierarchy Data using the NeedDataSource event and the Self-Referencing method for generating the Hierarchy.

In the NeedDataSource event handler I have only this :

RadGrid1.DataSource = ClassLibrary1.Service.Getdata().Where(x => x.Monthdate == DateTime.Parse("2010-12-01 00:00:00.000"));

This returns a subset of my data and the Grid is displayed fine, with working sorting and paging and hierarchy browsing.

The problem occurs on Filtering, where a AsyncPostbackError exception event is raised with this information for the inner exception property :

        Message   "Object reference not set to an instance of an object."
        Stack Trace :

at Telerik.Web.UI.GridColumn.set_CurrentFilterValue(String value)

at Telerik.Web.UI.RadGrid.RaisePostBackEvent(String eventArgument)

at System.Web.UI.Page.RaisePostBackEvent(IPostBackEventHandler sourceControl, String eventArgument)

at System.Web.UI.Page.RaisePostBackEvent(NameValueCollection postData)

at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfte

I read that Hierarchy Filtering is not possible with the basic data binding method calling DataBind(). I am not using that method, so If you could tell me if the approach used is a correct one or the errors I'm getting are triggered by some other problem?

Thanks in Advance.

RadWindow

Here is my problem:

I have RadWindow with NavigateUrl

function ShowDriverWindow(sender, eventArgs) {

var hack = "499628";

var url = "DriverInfo.aspx?hack=" + hack;

var oWnd = radopen(url, "RadWindowDriverInfo");

eventArgs.set_cancel(true);

}

I pass the parameter "hack" to the navigate page.
On this page i have LINQ querry to get info about this driver in Page_Load().

var driverInfo = (from dr in db.T_DRIVERs

where dr.HACK_ID == int.Parse(hackId)

select new {

...

dr.MEDALLION_ID,

...

}).Single();

then I set the Selected Value in RadComboBox according to the LINQ querry

RadComboBoxSteadyMedl.SelectedValue =

driverInfo.MEDALLION_ID.ToString();

And now my problems start. I have "Save" button. When i change value in RadComboBox and click "Save" i still have predefined value. So
no changes are done.

If I Don't set the driver's medallion in Page_Load() everything works fine! after selecting new item in ComboBox I have new "selected value" in SaveButton_Click.

Any ideas???

RadGrid Batch Update - Disable Textbox in a TemplateColumn

I'm working on the RadGrid batch update like the one shown in one of the demos. I need to disable textbox in a template column of the RadGrid based on the condition.

If the column was a BoundColumn I would use the following code in the Grid's PreRender event. But how to handle this with the batch update Grid and a TemplateColumn.

Private Sub RadGrid1_PreRender(ByVal sender As Object, ByVal e As System.EventArgs) Handles RadGrid1.PreRender

Dim status As String = Request.QueryString(0)

If status = "Future" Then

For Each column As GridColumn In RadGrid1.Columns

If (column.UniqueName = "Start_Dt") Then

CType(column, GridBoundColumn).ReadOnly = False

CType(column, GridBoundColumn).DataFormatString = "{0:D}"

Exit For

End If

Next

Else

For Each column As GridColumn In RadGrid1.Columns

If (column.UniqueName = "BoundDate") Then

CType(column, GridBoundColumn).ReadOnly = True

CType(column, GridBoundColumn).DataFormatString = "{0:D}"

Exit For

End If

Next

End If

End Sub

Thank you!!

How to run a Javascript when toggling RadScheduler View

I've got a RadScheduler with a height set by Javascript. I'd like to run some additional Javascript function (to maintain the height) when a user clicks to toggle the view between Day / Week / Month / Timeline. Is there some client event that fires when these buttons are clicked, or some other way to maintain a height parameter that has been set on the client side?
