Hello!

I am attempting to send the an ID value from one RadGrid Row to a RadGrid in a modal window as a DataKey using rowIndex. 

I sucessfully get the cell value but right now it is just sending it to OwnerTableView rather than my modal window grid.

aspx.cs code:

I only want the modal Grid to populate with values that also have that ID (multiple values).

Any thoughts on this?

Hi 

Im using Radgrid ExportToExcel() but getting this vulnerability caused the exported file to be broken 

is there any workaround for this?

Hi Team,

Telerik 2021.3.914.45,Edge Browser,.Net FramworkVersion- 4.8

Getting error with ArrayList GetAllNodes()

ArrayList allNodes = _treeView.GetAllNodes();    //Gettting error 
 for (int i = 0; i < allNodes.Count; i++)
                    {
                        RadTreeNode node = allNodes[i];                                      //Getting Error
                        if (node.Checked && node.Parent == null)
                    }

Tried with below changes:
 List<Telerik.Web.UI.RadTreeNode> allNodes = (List<Telerik.Web.UI.RadTreeNode>)_treeView.GetAllNodes();

Can anyone help me out to resolve the above issue  with sample code?

I am preparing dynamic grid using VB.net and RAD grid where columns are getting generated in Run Time. I am trying to apply filter (inbuilt filter) on multiple column at time but application is throwing exception (is neither a DataColumn nor a DataRelation for table Table). This error occurs when I try to apply filter. I am unable to identify root cause. Any input would be appreciated. I am using NeedDataSource() event of Radgrid and this event is throwing above mentioned exception on applying filter.

.Telerik page setting:

<telerik:RadGrid ID="gridData" runat="server" OnGridExporting="grid_GridExporting" RenderMode="Auto" ClientIDMode="AutoID" >
                    </telerik:RadGrid>

Code-behibd setting:

On page_load():

If Not ds Is Nothing Then
                DefineGridStructure(Session("DynamicResultReportGridData"))
                gridData.DataBind()

end

--------------------------

   Private Sub DefineGridStructure(ByVal allCloumnData As DataSet)

        'Dim grid As New RadGrid()

        gridData.DataSource = allCloumnData
        Session.Add("DynamicResultReportGridData", allCloumnData)
        gridData.Skin = "Default"
        gridData.Width = Unit.Percentage(100)
        gridData.PageSize = 15
        gridData.AllowPaging = True
        gridData.AllowFilteringByColumn = True
        gridData.PagerStyle.Mode = GridPagerMode.NextPrevAndNumeric
        gridData.AutoGenerateColumns = False

        'Add Customers table
        gridData.MasterTableView.Width = Unit.Percentage(100)

        Dim intVal As Integer = allCloumnData.Tables(0).Columns.Count
        For a = 0 To intVal - 1
            Dim boundColumn As New GridBoundColumn()
            boundColumn.DataField = allCloumnData.Tables(0).Columns(a).Caption().Trim().ToString()
            boundColumn.HeaderText = allCloumnData.Tables(0).Columns(a).Caption().Trim().ToString()
            boundColumn.UniqueName = allCloumnData.Tables(0).Columns(a).Caption().Trim().ToString()
            boundColumn.ItemStyle.CssClass = "text2"

            boundColumn.HeaderStyle.CssClass = "GridHeader"
            boundColumn.AllowFiltering = True
            gridData.MasterTableView.Columns.Add(boundColumn)
        Next
    End Sub

----------------------------------------------------

Protected Sub gridData_NeedDataSource(ByVal Source As Object, ByVal e As Telerik.Web.UI.GridNeedDataSourceEventArgs) Handles gridData.NeedDataSource

        gridDiv.Visible = True
        gridDiv1.Visible = True
        gridData.Visible = True
        Dim allCloumnData As DataSet = Session("DynamicResultReportGridData")
        If allCloumnData Is Nothing Then
        Else
            gridData.DataSource = allCloumnData
        End If


    End Sub

Hi Team,

We have migrated all RadTreeView Classic to RadTreeView Ajax Controls.

https://docs.telerik.com/devtools/aspnet-ajax/controls/treeview/appearance-and-styling/migrating-skins 

Modified existing skin as per above document but could not find anything related to SingleSelect_Hover,SingleSelect_Select,Disabled.

 private const string SINGLE_SELECT_HOVER_CSS_CLASS = "TreeNodeOver_SingleSelect";
        private const string SINGLE_SELECT_CSS_CLASS = "TreeNodeSelect_SingleSelect";
        private const string DISABLED_CSS_CLASS = "TreeNodeDisabled";
