Nested Grid

Hello,

Hope someone can help me out, i'm struggling with some thing that i want to do.

I have

public class AttributeValue

{

public string Name {get;set;}

public string Value {get;set;}

}

public class Entry

{

public string EntryName {get;set;}

public List<AttributeValue> Attributes {get;set;}

}

All i want to do is binding a List<Entry> to a RadGrid and then show the Attributes as a columns. i'm thinking about having the Attributes radgrid inside the Entry radgrid.

<telerik:RadGrid ID="rgEntry" runat="server">

<MasterTableView>

<Columns>

<telerik:GridTemplateColumn>

<ItemTemplate>

<telerik:RadGrid ShowHeader="false" ShowFooter="false" runat="server" ID="rgAttributes">

</telerik:RadGrid>

</ItemTemplate>

<HeaderTemplate>

</HeaderTemplate>

</telerik:GridTemplateColumn>

</Columns>

</MasterTableView>

</telerik:RadGrid>

Do you think i'm in the right way ? Or should i used Hierarchical Rad Grid or NestedViewTemplate ?

Thanks in advance

Know the records after filtering

Is there a way to know which records are returned after applying a filter? I need to gather all values of the key field when the records in the grid changes.

I have tried collecting the key value of each record in ItemDataBound event but that only returned records in one page. When there are more than one page, records in subsequent pages cannot be accessed through ItemDataBound.

RadGrid - Column Sort Behavior

I would like to change the sort behavior of the columns in my RadGrid. Currently, when you click on a column, it sorts ascending. I agree this is probably by design, but of course my client wants the column sorting descending when you first click the column. Is this something that can easily be done? A grid property??

Thanks in advance.

Column chooser support

I would like to implement a column chooser for the RADTreeList as the standard control does not have this functionality. Just wondered if anyone else has already done this and what method/control they have used. I had thought of using the RADWindow as this seemed to be a simple popup window which I could display when invoked (maybe from a context menu).

Unfortunately it seems that the RADWindow is not quite what I thought - I really wanted a simple popup container window. Thanks for any other suggestions?

RadGrid, RadWindow and RadComboxBox combination

Hi,

I already read this :
http://demos.telerik.com/aspnet-ajax/controls/examples/integration/gridandwindow/defaultcs.aspx?product=grid

Basically i want to do the same thing, maybe you can point me to an example.

What i want to do is :
I have a RadGrid that has 3 RadComboBox (in edit and insert mode).

For each radcombobox i want to have a hyperlink "Add new Item" that basically opens a new RadWindow (with a user controls inside), and when the user insert the new item, the radcombobox will be automatically updated, sorted and the new value selected without refreshing the page.

If anyone can hook me up with how to do this or any example ?

Thanks in advance

[Solved] RadMenu Skin Bug?

Hello,

Not all the skins have this error but I have noticed Outlook and WebBlue do. I'm not sure how to explain it which is why I have attached a screen shot. I am using Telerik version: 2010.1.519.35 and I have seen this in IE 7-9 as well as Safari 5.0.3 and Firefox 5.
Here is the code:

<telerik:RadMenu ID="RadMenu1" Skin="WebBlue" OnClientItemClicking="myClickFunction" runat="server" Flow="Horizontal">

<ExpandAnimation Type="InOutQuad" />

</telerik:RadMenu>

GridGroupByException: Expression cannot be null or empty

I have a RADGrid that requires that it's columns get removed and replaced per the context under which the data is being loaded. When the grid first loads, the Grouping operation runs fine. However, when the context changes and the Grid structure is reinitialized, when I try to group by any column I get the GridGroupByException: Expression cannot be null or empty error.

I start out with a Radgrid without column definitions. When the page loads, I invoke a procedure that first clears the Grids grouping, context menu, data binding and column settings then it runs an initialization routine to configure the grid for the data that will be loaded.

Here's the code for the ClearGridSettings method that's run first:

Private Sub ClearGridSettings()

' - Clear Grouping/Sort Levels

' - Clear Context Menus

' - Clear Data Bindings

' - Clear Columns

With grdSubmission

'Clear Grouping/Sort Levels

.MasterTableView.GroupByExpressions.Clear()

.MasterTableView.SortExpressions.Clear()

'Clear Context Menus

.ClientSettings.ClientEvents.OnRowContextMenu = ""

'Clear Data Bindings

.DataSource = ""

.DataBind()

'Clear Columns

.Columns.Clear()

End With

End Sub

Here's the code for the first Intialization:

Private Sub InitializeSubmissionGrid(ByVal GridViewSchema As Int16)

'##########################################

'Initialize Data Grid for Submission Claims Review

' - Reset Grid

' - Get GridView Schema for Submissions Claim Listing

' - Implement Column Structure

' - Set Miscellaneous Parameters

'###########################################

ClearGridSettings()

'Get Grid View Schema for Submissions View

Dim objDW As New DWGlobals

Dim ds As DataSet = objDW.GetGridViewSchema(GridViewSchema)

With grdSubmission

'Add Columns to Grid

For Each objRow As DataRow In ds.Tables(0).Rows

Dim objCol As New GridBoundColumn()

.MasterTableView.Columns.Add(objCol)

objCol.DataField = objRow("ColName")

objCol.HeaderText = objRow("ColName")

If Not IsDBNull(objRow("FormatString")) Then

objCol.DataFormatString = objRow("FormatString")

End If

objCol = Nothing

Next

' Set Miscellaneous parameters

.ClientSettings.Resizing.AllowResizeToFit = True

.ClientSettings.Resizing.AllowColumnResize = True

.ClientSettings.Scrolling.AllowScroll = True

.ClientSettings.Scrolling.UseStaticHeaders = True

.AutoGenerateColumns = False

.MasterTableView.GroupsDefaultExpanded = False

.MasterTableView.GridLines = GridLines.Both

.MasterTableView.AllowFilteringByColumn = False

.MasterTableView.Caption = txtSubmLabel.Text & "...(Claim Qty: " & txtClaimQty.Text & " )"

End With

End Sub

Here's the initialization code for the context change that's causing the error:

Private Sub InitializeFindingsGrid(ByVal GridViewSchema As Int16)

'##########################################

'Initialize Data Grid for Validation Findings Review

' - Reset Grid

' - Get GridView Schema for Validation Findings Listing

' - Implement Column Structure

' - Set Miscellaneous Parameters

'###########################################

ClearGridSettings()

'Get Grid View Schema for Submissions View

Dim objDW As New DWGlobals

Dim ds As DataSet = objDW.GetGridViewSchema(GridViewSchema)

objDW = Nothing

Dim exp As New GridGroupByExpression()

Dim gbf As New GridGroupByField()

With grdSubmission

'Add Columns to Grid

For Each objRow As DataRow In ds.Tables(0).Rows

Dim objCol As New GridBoundColumn()

objCol.DataField = objRow("ColName")

objCol.HeaderText = objRow("ColName")

objCol.UniqueName = objRow("ColName")

If Not IsDBNull(objRow("FormatString")) Then

objCol.DataFormatString = objRow("FormatString")

End If

objCol.GroupByExpression = objRow("ColName")

'Add GroupByField to GroupByExpression

'gbf = New GridGroupByField

'With gbf

' .FieldName = objRow("ColName")

' .HeaderText = objRow("ColName")

' .HeaderValueSeparator = " HeaderValSep "

' .Aggregate = GridAggregateFunction.Count

'End With

'exp.SelectFields.Add(gbf)

.MasterTableView.Columns.Add(objCol)

objCol = Nothing

Next

'Add GroupByExpression object to table

' .MasterTableView.GroupByExpressions.Add(exp)

' Set Miscellaneous parameters

.ClientSettings.Resizing.AllowResizeToFit = True

.ClientSettings.Resizing.AllowColumnResize = True

.ClientSettings.Scrolling.AllowScroll = True

.ClientSettings.Scrolling.UseStaticHeaders = True

.AutoGenerateColumns = False

.MasterTableView.GroupsDefaultExpanded = False

.MasterTableView.GridLines = GridLines.Both

.MasterTableView.AllowFilteringByColumn = False

.MasterTableView.Caption = "Findings For " & txtSubmLabel.Text & _

"...( " & txtFindingType.Text & ")"

'Enable Grid Options for Findings Review

.AllowMultiRowSelection = True

.ClientSettings.Selecting.AllowRowSelect = True

.ClientSettings.Selecting.EnableDragToSelectRows = True

.ClientSettings.ClientEvents.OnRowContextMenu = "RowContextMenu"

End With

exp = Nothing

gbf = Nothing

End Sub

As you can see by the commented out section I tried to explicitly set GridGroupByFields but that didn't work either. I also tried setting the GroupByExpression on a column by column basis with the same result.

What am I missing?
