can anyone suggest a way of persisting the visiblilty of a node after postback.

I am using javascript to node.set_visible(false) and using a tree.trackChanges() and tree.commitChanges() around my code...

All other settings such as enabled/disabled and css styles are honoured on each node... but this setting does not seem to be... am I missing something?

1. I have RadGrid
2. I have DetailTable 
3. All master rows have detail rows
4. All rows expanded

Why get_nestedViews()[0] have value only for first row in master grid?!

                var grid = $find("<%=masterGrid.ClientID %>");
                 var rows = grid.get_masterTableView().get_dataItems();

                    for (var i = 0; i < rows.length; i++) {
                        if (rows[i].get_nestedViews().length > 0)
                        {
                            var nestedView = rows[i].get_nestedViews()[0];
                            .......
                        }                        

Dear Team,

I have a rad Grid, with in which I have created a  checkbox column and assing the Data to this grid. The check box is getting check or unchecked according to the Data. Perferct till here.

<telerik:GridTemplateColumn HeaderText="IsIndividual" UniqueName="IsIndividual" ReadOnly="true">
<ItemTemplate>
<asp:CheckBox ID="chkboxIsIndividual" runat="server" />
</ItemTemplate>
</telerik:GridTemplateColumn>

But this check box appears editable, I can uncheck/ check it in the Grid. But I want this column to be read Only. The grid should show checked/unchecked as per the data but should not allow to edit this checkbox. When I try to make the enable property to false, all the records a show checked, which is incorrect :(


Below is the code in the
radCBTransactionDetails_ItemCreated to check/uncheck the checkbox.

if (column.UniqueName == "IsIndividual" && column is GridTemplateColumn)
{
CheckBox chk = (CheckBox)e.Item.FindControl("chkboxIsIndividual");
// chk.Enabled = false;
if (gridItem.OwnerTableView.DataKeyValues[gridItem.ItemIndex]["IsIndividual"].ToString().ToUpper().Equals("TRUE"))
{
chk.Checked = true;
//chk.Enabled = false;
editLink.Text = "ViewIndividual";
}
else if (gridItem.OwnerTableView.DataKeyValues[gridItem.ItemIndex]["IsIndividual"].ToString().ToUpper().Equals("FALSE"))
{
chk.Checked = false;
//chk.Enabled = true;
editLink.Text = "Bulk";

}
}​

Please help me with this asap.

Hello,

I have a RadEditor that is supposed to use the Image Manager that allows them to upload and insert pictures. Here is my code for formatting it from the C# side. The imgPath created is a virtual path.



I create a string that creates the virtual path in imgPath, then if the directory does not exist, I create it so the imgPath exists for sure. Then I attempt to set the View and Upload path of the image manager to have those folders. However, when I open the image manager, this is what I see: (attached .png image)

The way it looks it seems that my paths are not being set. Why is this? The imgPath is the correct virtualPath. 

  

my raddropdowntree appears always at the top of html DOM , before the form , with absolute position

        }

    .rmSlide {
        display: inline-block !important;
        padding-left : 154px;
    }
}


It behaves too bad on hover effect and Sub Menu item always comes on top instead of inline with its parent item.

Can any one help me out?

I am having a problem with clearing filter value. I need to set ListOfFilterValues = Nothing for a GridBoundColumn. My code is as follows:

If TypeOf column Is GridBoundColumn Then
     Dim boundColumn As GridBoundColumn = TryCast(column, GridBoundColumn)
     boundColumn.FilterListOptions = GridFilterListOptions.AllowAllFilters
     DirectCast(column, Telerik.Web.UI.GridBoundColumn).ListOfFilterValues = Nothing

End If

However I am getting the error

Error 1 'Telerik.Web.UI.GridColumn.Protected Friend Property ListOfFilterValues As String()' is not accessible in this context because it is 'Protected Friend'. 

Any solution?

Thanks
