RadUpload input placement chrome/firefox bug?

I found that the radupload gets translated into a series of input tags.

the input type=file is just chilling at position: absolute; left: 0px; top: -5000px;

this happens while the hover over is not fired.

The problem with this is that my page is rather large and -5000 px before the upload
is some checkbox

So when i click on the checkbox a File browse fires and i'm prompted to upload
a file instead of just checking the current checkbox.

Is there a fix for this? I tried hiding the input but that renders the control useless.

Upload (Obsolete)

Get Reference To A DetailsView column on the DetailTableDataBind

Hi

I have a RadGrid with Master and Detail views. The load mode for the details view is HierarchLoadMode="ServerOnDemand". I am binding the details view on the RadGrid DetailTableDataBind event.

I am trying to set the value of one of the detail fields to a value from the master table view but can't figure out how to get a reference to the detail row/field being bound.

Thank you for your assistance

Tracy

Private Sub rgvDataExceptions_DetailTableDataBind(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridDetailTableDataBindEventArgs) Handles rgvDataExceptions.DetailTableDataBind

Dim SelectedRow As GridDataItem = CType(e.DetailTableView.ParentItem, GridDataItem)

Dim intException As Int32 = SelectedRow.GetDataKeyValue("ExceptionID")

Dim detailTable As GridTableView = DirectCast(SelectedRow.ChildItem.NestedTableViews(0), GridTableView)

SQLDS_DataExceptionsMessage.SelectParameters.Clear()

SQLDS_DataExceptionsMessage.SelectParameters.Add("intExceptionId", intException)

e.DetailTableView.DataSource = SQLDS_DataExceptionsMessage

'Get value from master table row

Dim strExceptionMessage As String = SelectedRow("ExceptionMessage").Text 



            I would then like to set the bltExceptionMessage,which is a bulled list that is in a template column of the details view

'Dim bltMessages As BulletedList = DirectCast(SelectedRow.FindControl("bltExceptionMessage"), BulletedList)

'Dim aryMessages As New ArrayList

'aryMessages.AddRange(Split(strExceptionMessage, "~"))

'bltMessages.DataSource = aryMessages

'bltMessages.DataBind()

End Sub

DestroyOnClose not working

I originally posted this as a reply to a year old post.

I have a RadWindowManager with DestroyOnClose='true' but on every postback, even after closing the window theRadWindowManager's Windows collection still contains the window. I do not have VisibleOnPageLoad set. Instead, on every load, I run the following javascript.

function openPromoteWindows(RadWindowManagerId) {

var oManager = $find(RadWindowManagerId);

var oWindows = oManager.GetWindows();

for (i = 0; i < oWindows.length; i++) {

var oWindow = oWindows[i];

oWindow.show();

oWindow.Minimize();

oWindow.get_popupElement().style.zIndex = 10000 + i;

}

This successfully opens all the windows minimized inside a taskbar. The problem is that since closed windows are still in the Windows Collection, they reappear.

I did write some code called "OnClientClose that does successfully delete the window from the windows collection on the client side, but it doesn't persist. That code is below:

function rwmPromote_Close(sender, eventargs) {

var rwm = $find(window['rwmPromoteId']);

var oWindows = rwm.GetWindows();

var i;

for (i = 0; i < oWindows.length; i++) {

var oWindow = oWindows[i];

if (oWindow == sender)

break;

}

if (i < oWindows.length) {

rwm._windows.splice(i, 1);

}

This code was added in desperation to try and get the information persisted to the server side. I tried setting EnableViewState to false, but as expected that makes it forget about all Windows in the Windows collection except for ones added during that postback, which means it does forget about closed windows but also forgets about minimized windows.

I am about to add a HiddenField which will contain the ClientIDs of all Windows and then I will use that server side to deduce which windows, if any, were closed. While I am hopeful this will work, I am sure it's not the way it is supposed to work.

Added later! I have implemented the HiddenField solution as follows and it works successfully, but I don't think this is the proper way to achieve my goal.

function rwmPromote_Close(sender, eventargs) {

var rwm = $find(window['rwmPromoteId']);

var hf = $get(window['hfWindowIdsId']);

hf.value = '';

var oWindows = rwm.GetWindows();

var i;

for (i = 0; i < oWindows.length; i++) {

var oWindow = oWindows[i];

if (oWindow == sender)

break;

}

if (i < oWindows.length) {

rwm._windows.splice(i, 1);

oWindows = rwm.GetWindows();

for (i = 0; i < oWindows.length; i++) {

hf.value += oWindows[i].id + ',';

}

and in the code behind.

// At the conclusion of every postback

hfWindowIds.Value = "";

foreach (RadWindow rw in rwmPromote.Windows)

{

hfWindowIds.Value += rw.ClientID + ',';

}

// And then on the ValueChanged event for the HiddenField

protected void hfWindowIds_ValueChanged(object sender, EventArgs e)

{

char[] sep = {','};

string[] WindowIds = ((HiddenField)sender).Value.Split(sep, StringSplitOptions.RemoveEmptyEntries);

List<RadWindow> rwList = new List<RadWindow>();

foreach (RadWindow rw in rwmPromote.Windows)

{

if (!WindowIds.Contains(rw.ClientID)) rwList.Add(rw); // No longer open client side

}

foreach (RadWindow rw in rwList)

rwmPromote.Windows.Remove(rw); // Remove each closed window

}

This is all working, but I would pre3fer to know the "correct" way to achieve my goal.

Suggestions welcomed!!

ExportCellFormatting and PDF

I am trying to horizontally align specific cells when exporting the same as their ItemStyle in the markup. I've followed several links and have it working for Excel but PDF does not.

The ExportCellFormatting event handler does not appear to fire when exporting to PDF like it does for Excel. I believe this event is supposed to be a replacement for the deprecated ExcelExportCellFormatting event, but I would think based off the name and the deprecation of its predecessor that this should fire for PDFs as well.

ExportCellFormatting is the only event that I've found thus far where the cell's HorizontalAlign is set (off the e.FormattedColumn.ItemStyle) -- if I check the cell's HorizontalAlign in either the ItemCreated or ItemCommand event handlers it is always HorizontalAlign.NotSet. The PdfExporting event only exposes the raw HTML, which I can manipulate, but that is tedious.

I am able to get basic formatting to occur for PDF so long as it isn't related to checking something set in the markup. For example, I can detect whether the ItemType is an Item or AlternatingItem and set the inline style accordingly for alternating rows, and set the basic font, font size, and header formatting.

How can I format what's exported to PDF based on the formatted columns, specifically the horizontal alignment of individual cells? Below are code samples of what I have working so far.

<jha:RadGrid ID="grdVendors" runat="server" DataSourceID="odsVendors"

OnItemDataBound="grdVendors_ItemDataBound" OnItemCommand="grdVendors_ItemCommand"

OnExportCellFormatting="grdVendors_ExportCellFormatting" OnItemCreated="grdVendors_ItemCreated" OnPdfExporting="grdVendors_PdfExporting">

<MasterTableView DataKeyNames="VendorID">

<Columns>

<telerik:GridBoundColumn HeaderText="ID" DataField="VendorID" Visible="false" />

<telerik:GridBoundColumn HeaderText="First Name" DataField="FirstName" />

<telerik:GridBoundColumn HeaderText="Last Name" DataField="LastName" />

<telerik:GridBoundColumn HeaderText="City" DataField="City" />

<telerik:GridBoundColumn HeaderText="State" DataField="State" ItemStyle-HorizontalAlign="Center" />

<telerik:GridBoundColumn UniqueName="CreatedOn" HeaderText="Created On" DataField="CreatedDateTime"

DataFormatString="{0:MM/dd/yyyy}" ItemStyle-HorizontalAlign="Right" />

</Columns>

</MasterTableView>

</jha:RadGrid>

protected void grdVendors_ItemCommand(object sender, GridCommandEventArgs e)

{

switch (e.CommandName)

{

case RadGrid.ExportToExcelCommandName:

case RadGrid.ExportToPdfCommandName:

grdVendors.CssClass = "export";

string title = "Foo";

GridExportSettings settings = grdVendors.ExportSettings;

settings.ExportOnlyData = true;

settings.OpenInNewWindow = true;

settings.IgnorePaging = true;

settings.HideStructureColumns = true;

settings.FileName = string.Format("{0} {1:yyyy-MM-dd}", title, DateTime.Now);

// PDF

settings.Pdf.DefaultFontFamily = "Tahoma";

settings.Pdf.PageTitle = title;

settings.Pdf.Title = title;

settings.Pdf.AllowPrinting = true;

settings.Pdf.AllowAdd = false;

settings.Pdf.AllowCopy = true;

settings.Pdf.AllowModify = false;

settings.Pdf.PageWidth = Unit.Parse("297mm");

settings.Pdf.PageTopMargin = Unit.Parse("20mm");

settings.Pdf.PageHeaderMargin = Unit.Parse("10mm");

settings.Pdf.PageBottomMargin = Unit.Parse("10mm");

settings.Pdf.PageLeftMargin = Unit.Parse("10mm");

settings.Pdf.PageRightMargin = Unit.Parse("10mm");

break;

}

protected void grdVendors_ExportCellFormatting(object sender, ExportCellFormattingEventArgs e)

{

/// Never fires when exporting to PDF

switch (e.FormattedColumn.ItemStyle.HorizontalAlign)

{

case HorizontalAlign.Left:

e.Cell.Style["text-align"] = "left";

break;

case HorizontalAlign.Center:

e.Cell.Style["text-align"] = "center";

break;

case HorizontalAlign.Right:

e.Cell.Style["text-align"] = "right";

break;

}

if (e.FormattedColumn.UniqueName == "PostalCode")

e.Cell.Style["mso-number-format"] = @"\@";

}

protected void grdVendors_ItemCreated(object sender, GridItemEventArgs e)

{

if (grdVendors.CssClass.Contains("export"))

{

if (e.Item is GridDataItem)

{

foreach (TableCell cell in e.Item.Cells)

{

if (e.Item.ItemType == GridItemType.AlternatingItem)

cell.Style["background-color"] = "#E6EFF7";

else

cell.Style["background-color"] = "#FFFFFF";

}

else if (e.Item is GridHeaderItem)

{

Table table = e.Item.Parent.Parent as Table;

table.Style["font-family"] = "Tahoma";

table.Style["font-size"] = "8pt";

foreach (TableCell cell in e.Item.Cells)

{

cell.Style["border-color"] = "#FFFFFF";

cell.Style["background-color"] = "#EEEEEE";

cell.Style["text-align"] = "left";

cell.Style["color"] = "#274777";

cell.Style["font-weight"] = "bold";

}

Configure RadSplitter into Sections

I am working with the RadSplitter, and I have the following requirement:

<RadSplitter>
<RadToolBar> - spans across entire width of RadSplitter
<RadPane Width="20%" />
<RadSplitBar />
<RadPane Width="80%" />
</RadSplitter>

Is it possible to have a RadToolBar span the entire length of a RadSplitter at the top, with two RadPanes below the RadToolBar?

- similiar to how an html table can be customized;

Thanks in advance for any insight;

License question

Hi,
I'm wondering if the license gives possibility of creation of CMS which uses the telerik controls?
What is the meaning of "design time" working with controls. If I create the CMS where on the web page users will be able to create their own websites and I design modules which are based on telerik controls does this mean that I do not respect the license? Or the "design time" working with controls mean that they are used in the IDE like Visual Studio?

Can't find modified item in Update command

Hi all,

I got a grid with some lines. I am using an edit column and handle the update command, but I can't find the modified row in the "e". I guess it is somewhere in the e.Item.DataItem, but I can't see it.

Anyone can help me?
