Hi,
I want to be able to upload and download files (.doc, .docx, .pdf) to binary field in SQL Server database using RadGrid and AsyncUpload. A row in the grid should have a download link in the first column and document name and description in other columns. When in edit mode, I need to be able to upload file using AsyncUpload and add document name and description through textboxes in different collumns.
Please, is there any example of such scenario?

RadAsyncUpload Control

Hi,

I need to use RadAsyncUpload to upload the files and then save the file into database in code-behind. Everything works fine except the "InputStream" throws a file not found exception. I looked at the folder where the files are uploaded. Originally, the file name contains a series of number then the actual file name. After post, the file got renamed back to the actual file name! That's why the UploadedFile.InputStream cannot find the file. If the file is renamed, the input stream should look for the file with the renamed file name.

I can go around this problem of course, but I think you guys should fix this issue. (I have the latest version of Telerik library.) By the way, I can't use the "OnFileUploaded" event because I need to create my own object first. Then, these files are the attachments of my object.

If you want to see some code:
.aspx:
<telerik:RadAsyncUpload runat="server" ID="rauAttachment" HideFileInput="true" MultipleFileSelection="Automatic" TargetFolder="~/UserFiles/Temp/" Localization-Select="Attach Files" Width="88" OnClientValidationFailed="RauValidationFailed" />

.aspx.cs: Submit button click event:
Stream stm = rauAttachment.UploadedFiles[0].InputStream; //File not found exception occurs.

Regards,

Roger

adding/deleting RibbonBarMenuItems javascript clientside

Hi All!

I am trying to insert/delete RibbonBarMenuItems in RibbonBarMenu using Javascript clientside.
I cannot find any documentation on how this is done.

I have tried doing it the same as it is done in RadMenu:
    menu.trackChanges();
    menu.get_items().add(item);
    menu.commitChanges();
but this attempt was unsuccessful.

Any help will be much appreciated.
Thanks in advance!!

Compare mime type againt file extension

How can I validate that the file I have uploaded has right mime type if compared with the file extension?

I want to support all browsers. It means well that I must do the validation on the server. Or?
And how should I do?

Right now I use RadUpload and validates against the file extensions, it works well. But like I say I also want to make sure that the file extension matches the mine type.

Grateful for the tips!
Best regards,
Foppa

Autopostback not firing on TabStrip with Multipage

Hi,

I've implemented a load-on-demand radtabstrip with radmultipage using the telerik demo. This works fine. Each tab shows an ascx control which holds a different Radgrid.
I then tried to implement the RenderSelectedPageOnly by setting this to "true" & setting AutoPostBack to "true" on the TabStrip.
However, this did not work. When i load my page, the default tab loads & when i click on to another tab then this loads correctly.
BUT if i click back on to a tab i already viewed, it displays a blank tab with no radgrid. I tried to trace the AutoPostBack but it does not seem to be firing.
All i want to do is render the selected page of the TabStrip but when another tab is selected (regardless of whether it has been rendered before) load the newly clicked Tabs page contents.
My code is as follows:

HTML:

<telerik:RadTabStrip OnClientTabSelecting="onTabSelecting" ID="RadTabStrip1" SelectedIndex="0" runat="server" MultiPageID="RadMultiPage1"

OnTabClick="RadTabStrip1_TabClick" Width="900px" AutoPostBack="true" >

</telerik:RadTabStrip>

<telerik:RadMultiPage ID="RadMultiPage1" runat="server" SelectedIndex="0" OnPageViewCreated="RadMultiPage1_PageViewCreated" Width="900px" RenderSelectedPageOnly="true" >

</telerik:RadMultiPage>

JAVASCRIPT:

function onTabSelecting(sender, args) {

if (args.get_tab().get_pageViewID()) {

args.get_tab().set_postBack(false);

}

.CS

protected void Page_Load(object sender, EventArgs e)

{

if (!Page.IsPostBack)

{

AddTab("MyForms");

AddPageView(RadTabStrip1.FindTabByText("MyForms"));

AddTab("MyApprovals");

AddTab("MySystemsApprovals");

AddTab("MyGateKeeperApprovals");

}

private void AddTab(string tabName)

{

RadTab tab = new RadTab();

tab.Text = tabName;

RadTabStrip1.Tabs.Add(tab);

}

private void AddPageView(RadTab tab)

{

RadPageView pageView = new RadPageView();

pageView.ID = tab.Text;

RadMultiPage1.PageViews.Add(pageView);

pageView.CssClass = "pageView";

tab.PageViewID = pageView.ID;

}

protected void RadTabStrip1_TabClick(object sender, RadTabStripEventArgs e)

{

AddPageView(e.Tab);

e.Tab.PageView.Selected = true;

}

protected void RadMultiPage1_PageViewCreated(object sender, RadMultiPageEventArgs e)

{

string userControlName = e.PageView.ID + "CS.ascx";

Control userControl = Page.LoadControl(userControlName);

userControl.ID = e.PageView.ID + "_userControl";

e.PageView.Controls.Add(userControl);

}

Can anyone tell me what i'm doing wrong or why the autopostback is not firing when a viewed tab is selected again?
Is there a different way of getting the TabStrip to render selected page only but reload a different tab when clicked on?

Regards,

Shuja

RadUploadAjax callback error : Source url returned error : 12002

Hi,

I have a RadProgressManager and RadProgressArea on my ASPX Page which opens in a RadWindow.
<telerik:RadProgressManager id="Radprogressmanager1" runat="server" RegisterForSubmit="false" />
<telerik:RadProgressArea id="RadProgressArea1" runat="server" />

We try to copy data from one table to another table when that copy is occuring the Progressmanager kicks in ans shows how much percent of copying is done.

After the copying is started it, progress bar is getting stuck in certain point and giving the attached error message.
RadUploadAjax callback error : Source url returned error : 12002.

I don't know why it is behaving like this.

I registered it correctly in web.config. Don't what is triggering this issue.

Any help would be appreciated.

Thanks,
