Looking for a recommendation of the best way to accomplish this: I have a RadWindow that users can use to navigate between a few different pages within the RadWindow. They navigate by clicking ASP HyperLinks.

What I would like to be able to do is put a "back" button on each page that allows them to return to the previous page. I thought using ViewStates might be a solution, but I'm not sure how to implement it.

I appreciate any feedback.

Is it possible...

Is it possible to allow users to upload an entire folder using the built-in document manager? I have a case where a user is responsible for uploading new video tutorials, and those tutorials have many "chapters", so each set of videos are approximately 15 files each per folder. Ideally I'd love to allow the user to just dump the folder, and not each file by file. Is this possible?

Finding asp.net controls on RadPageView with Javascript

I have a question regarding how to find and get the value of asp.net controls that are located within a RadPageView using Javascript. I have a form where I use the RadTabStrip in conjunction with the RadMultiPage. Each tab and RadPageView contain a User control which contains several asp.net label controls that display various data.

I need to access the values of several of these fields using Javascript. To do so, I had a javascript routine that got a reference to the PageView on the currently selected tab as follows:

// This function returns a reference to the pageview of the currenlty selected tab.

function GetCurrPageView() {

var rtabCarrLoc = $find("<%= rtabCarrierInfo.ClientID %>");

var rselectedtab = rtabCarrLoc.get_selectedTab();

if (rselectedtab) {

var rpageview = rselectedtab.get_pageView();

return rpageview;

}

The plan was then to use that reference to find, for example, a label control and extract its value. This proved difficult since the RadPageView does not seem to provide any methods to find controls contained within it.

I opened a support ticket with Telerik to solve this problem. They provided a solution to extract the contents of a label by using a unique CSS class by which I could find the label and get the contents. See the following for an example:

// Get and set the location name.

var rpageview = GetCurrPageView();

if (rpageview) {

var lblLocName = $telerik.$(".cdhdr-carrlocationheader", rpageview._element).html();

if (lblLocName) {

var DULocName = document.getElementById("<%= lblDataUpdLocName.ClientID %>");

DULocName.innerText = lblLocName;

}

The ".cdhdr-carrlocationheader" is the custom css class assigned to the label control that I extracted the value for. This works althought they never did explain exactly how. I have no idea what the "$telerik.$" function is, the parameters it offers, or how it works.

Anyway, my problem now is that I would also like to be able to find some "HiddenFields" on the pageview and extract their values. The above solution will not work for them since you cannot assign a CSS class to a Hiddenfield.

Does anyone know how I could do this? Any help would be greatly appreciated.

How to get the *actual* data value on ItemDataBound event

I have wired up an ItemDataBound handler for my radgrid. Pretty simple standard fare (see code snippet below). However, I've noticed while stepping through the debugger on this that when the column value that I'm retrieving is an empty string, I'm actually getting back " "... so my code never thinks it's an empty string... I realize I could code something that looks for " " but that seems fragile.

So I was wondering how I would access not the value from the radgrid column (which appears to be applying some formatting or whatever), but the actual, true blue underlying value from the data source.

Any references on how to do so would be greatly appreciated.

protected void gvMain_ItemDataBound(object sender, GridItemEventArgs e)

{

if (e.Item is GridDataItem)

{

GridDataItem gridRow = (GridDataItem)e.Item;

bool hasEamil = (gridRow["Email"].Text.Length > 0);

}

radgrid is auto incrementing column headers

When there are multiple column headers with the same name, the radgrid keeps adding a number to the end of the header. For example if I have repeating column headers that are aa, bb, cc, aa, bb, cc, aa, bb, cc the radgrid displayes them as aa, bb, cc, aa1, bb1, cc1, aa2, bb2, cc2 and so on. Is there a way to turn this off.
This is my code:
<telerik:RadGrid ID="RadGrid1" runat="server" DataSourceID="SqlDataSource3" Skin="Simple"
                CellSpacing="0" GridLines="None" Font-Size="8pt" CellPadding="0" Wrap="False">
                <MasterTableView DataSourceID="SqlDataSource3" CommandItemDisplay="Top" Font-Size="8" CellPadding="0" Wrap="False">
                    <ItemStyle Wrap="False" />
                    <CommandItemTemplate>
                        <%=gridHeader%>
                    </CommandItemTemplate>
                    <CommandItemSettings ShowExportToWordButton="true" ShowExportToExcelButton="true"
                        ShowExportToCsvButton="true" />
                    <RowIndicatorColumn FilterControlAltText="Filter RowIndicator column">
                        <HeaderStyle Width="20px"></HeaderStyle>
                    </RowIndicatorColumn>
                    <ExpandCollapseColumn FilterControlAltText="Filter ExpandColumn column">
                        <HeaderStyle Width="20px"></HeaderStyle>
                    </ExpandCollapseColumn>
                    <EditFormSettings>
                        <EditColumn FilterControlAltText="Filter EditCommandColumn column">
                        </EditColumn>
                    </EditFormSettings>
                </MasterTableView>
                <HeaderStyle Font-Size="8pt" Font-Underline="False" Wrap="False" />
                <FilterMenu EnableImageSprites="False">
                </FilterMenu>

            </telerik:RadGrid>
