Hi,
I am having data in Session and casting it to a Datatable.
and I want to delete some of the rows from that Datatable based on a comparison (please the code below).
it doesnt give the expected result.
could you please advise me on this??

DataTable dtchange = (DataTable)Session["Data"];
DataSet ds = getdata(txt_HideDual.Text.ToString());
if (dtchange.Rows.Count != 0)
{
for (int i = 0; i < dtchange.Rows.Count; i++)
{
for (int j = 0; j < ds.Tables[0].Rows.Count; j++)
{
if (dtchange.Rows[i]["Name"].ToString() == ds.Tables[0].Rows[j]["Name"].ToString())
{
//dtchange.Rows.RemoveAt(i); --- This doesnt work
dtchange.Rows[i].Delete();
dtchange.AcceptChanges();
}
}
}
Session["Data"] = dtchange;
}

Thanking you,

AGM Raja

Columns Not visible when enabling static headers and Frozen coumns

Hi,

we are displaing more than 120 columns in the Radgrid which are generated dynamically from the Store Procedure. we have enabled sorting, Filtering and DragandDrop.

The issue is that, some of the columns in the right most side is not visible when scrolling.

I have even set the Header Item style width and Filter Control width. Still it doesn' t work.

Any fix or work around for this?

Best Regards,
satz

GridView - CommandButton Move to Another Grid

I wrote an application for a client earlier this year that enables drag and drop functionality between two grids (assigned measures and available measures). The drag and drop works for most of their associates but for a few, it's not functional and they would like me to create a secondary way for them to select and move measures.

They asked for a single button that would allow them to select one or more rows in the available grid, click the button, and move selected rows to the assigned grid, but I thought in my research earlier this year that I found that wasn't possible. Is it? Or is it possible to create a command column in each grid with, for example, an arrow pointing to the other grid that when clicked would move the row?

Looking for a push in the right direction on this and examples would be greatly appreciated.

Thanks!

Grid Hierarchy with unknown -unlimited- hierarchy levels

I'm making a grid that displays file system directories and files as a hierarchy
The problem is it only works fine for only the first level of hierarchy, what I should do to make this supports unlimited levels.

here is my code:

ASPX:

<div>

<telerik:RadGrid ID="RadGrid1" runat="server" AllowMultiRowEdit="True"

AutoGenerateHierarchy="True" CellSpacing="0" GridLines="None"

Skin="Windows7" ondetailtabledatabind="RadGrid1_DetailTableDataBind">

<MasterTableView DataKeyNames="FullName,IsDirectory,ParentDirectory">

<DetailTables>

<telerik:GridTableView AutoGenerateColumns="true" DataKeyNames="FullName,IsDirectory,ParentDirectory">

</telerik:GridTableView>

</DetailTables>

</MasterTableView>

</telerik:RadGrid>

</div>

Code File:

public partial class Default : System.Web.UI.Page

{

protected void Page_Load(object sender, EventArgs e)

{

if (!IsPostBack)

{

List<FileWrapper> dirs = new DirectoryInfo("C://").GetDirectories().Select(obj => new FileWrapper(obj, true)).ToList();

List<FileWrapper> files = new DirectoryInfo("C://").GetFiles().Select(obj => new FileWrapper(obj, true)).ToList();

dirs.AddRange(files);

RadGrid1.DataSource = dirs;

RadGrid1.DataBind();

}

protected void RadGrid1_DetailTableDataBind(object sender, GridDetailTableDataBindEventArgs e)

{

GridDataItem dataItem = (GridDataItem)e.DetailTableView.ParentItem;

bool isDirectory = bool.Parse(dataItem.GetDataKeyValue("IsDirectory").ToString());

string FullName = dataItem.GetDataKeyValue("FullName").ToString();

if (isDirectory)

{

DirectoryInfo d = new DirectoryInfo(FullName);

List<FileWrapper> dirs = d.GetDirectories().Select(obj => new FileWrapper(obj, false)).ToList();

List<FileWrapper> files = d.GetFiles().Select(obj => new FileWrapper(obj, false)).ToList();

dirs.AddRange(files);

e.DetailTableView.DataSource = dirs;

}

public class FileWrapper

{

public string Name { get; set; }

public string FullName { get; set; }

public bool IsDirectory { get; set; }

public DateTime CreationTime { get; set; }

public string ParentDirectory { get; set; }

public List<FileWrapper> Children { get; set; }

public FileWrapper(object o, bool isRoot)

{

if (o is FileInfo)

{

FileInfo f = (FileInfo)o;

Name = f.Name;

FullName = f.FullName;

CreationTime = f.CreationTime;

IsDirectory = false;

if (!isRoot)

{

ParentDirectory = f.Directory.FullName;

}

if (o is DirectoryInfo)

{

DirectoryInfo d = (DirectoryInfo)o;

Name = d.Name;

FullName = d.FullName;

CreationTime = d.CreationTime;

IsDirectory = true;

if (!isRoot)

{

ParentDirectory = d.Parent.FullName;

}

How to disable Audio Code option on SocialShare SendEmail

Have deployed a website to Azure websites and one of the pages has a SocialShare Send Email button. The popup send email form includes the Radcaptcha and by default has the "Get Audio Code" option.

When visiting the page I get a message "This web page wants to run the following add-on: 'Windows Media Player" It took me awhile to figure out why and than noticed that the popup form generated from SocialShare SendEmail has the Audio code option.

So when debugging the page (on the basis that a user chooses not to select the Allow) when proceeding to redirect the page I get error: "An unhandled exception of type 'System.NullReferenceException' occurred in System.Speech.dll"

(note I don't get this error when running local).

I am assuming this is being caused by the SocialShare Radcaptcha needing the add-on and errors out without it.

In any case I am happy to disable the AudioCode option as I have also done this on another Radcaptcha on the same page.

Is there a way to disable the Audiocode option on SocialShare Send Email button?

Thanks

Only show ProgressArea when uploading files

Hi,

I have a simple page with a RadUpload, RadProgressArea and RadProgressManager.
When visitors upload one or more files, click on 'Upload Files', the files start uploading and the RadProgressArea
appears.

So far so good.

After uploading, I do a Request.RawUrl, meaning it reloads the page, binds a grid and shows the uploaded files.

Inside this grid there is a Download button. When you click this button, the file will be downloaded (forced with the Save As dialog).
When you click this buttons, the RadProgressArea appears again, and can't be cancelled or whatever.

I don't want this thing to show up, but only when actually uploading files.

Can I do something about it?

Thanks,
Daniel

setting validation group

I have a radtabstrip that I use as a wizard.
Each tab is a usercontrol. The user can navigate between the tabs using the prev and next buttons on the page or by clicking on the tabs.

I have a customvalidator on each of my tabs. They seem to work fine on the prev/next buttons. However when i use the tabs to navigate the validation does not work right the first time.

I am setting my validationgroup for the tabstrip as below:

<telerik:RadTabStrip ID="rtsBeneficiaryChange" SelectedIndex="0" runat="server" MultiPageID="rmBeneficiaryChange"

OnTabClick="rtsBeneficiaryChange_TabClick" EnableEmbeddedSkins="false" Skin="MBen"

OnClientTabSelected="UpdateValidationGroup"

CausesValidation="true" AutoPostBack="true">

</telerik:RadTabStrip>

script:

function UpdateValidationGroup(sender, args) {

// args.set_cancel(!Page_IsValid);

var tabStrip = sender;

var selectedTab = tabStrip.get_selectedTab();

if (selectedTab != null)

tabStrip.ValidationGroup = selectedTab.get_value();
