Hi,

I have not found a method for capturing when a selected node changes as the OnSelectedNodeChanged provided by asp:TreeView.
Do you know how to capture this event?
Thank you,
Sonia.

Issue with setting grid to false

I've been trying to figure out how to delete a radgrid, but it seems the best solution is to set its visibility to false and work off of that.

So i tried that, and now lets say i have 4 grids:

Grid1
Grid2
Grid3
Grid4

And i delete Grid3, and now i am left with:

Grid1
Grid2
Grid4

And i have a button that you can click on, that shows all the grids and the data in the grid, if i don't delete any grids it works fine, but if i delete one of the grids, i get the following error when i click to PreviewAll grids.

Failed to load viewstate. The control tree into which viewstate is being loaded must match the control tree that was used to save viewstate during the previous request. For example, when adding controls dynamically, the controls added during a post-back must match the type and position of the controls added during the initial request.

Below is the code i am using to "Delete the grid" which is just setting the visibility to false:

public void DeleteGrid(object sender, EventArgs e, PlaceHolder ph)

{

LinkButton gridLink = (LinkButton)sender;

String gridNum = gridLink.ID.ToString().Split('-').Last();

System.Web.UI.Page currentPage;

currentPage = (System.Web.UI.Page)System.Web.HttpContext.Current.Handler;

RadGrid grid = (RadGrid)currentPage.FindControl("RadGrid" + gridNum);

Label lbl = (Label)currentPage.FindControl("Break-" + gridNum);

LinkButton lbd = (LinkButton)currentPage.FindControl("Delete-Grid-" + gridNum);

LinkButton lb = (LinkButton)currentPage.FindControl("Show-Grid-" + gridNum);

grid.Visible = false;

lbl.Visible = false;

lbd.Visible = false;

lb.Visible = false;

HttpContext.Current.Session.Add(gridNum, null);

}

PreviewAll grids method, which runs and shows all the grids

public void PreviewAll(PlaceHolder ph)

{

ph.Controls.Clear();

for (int i = 1; i <= Convert.ToInt32(GetSession()); i++)

{

if (HttpContext.Current.Session[i.ToString()] == null)

{

HttpContext.Current.Response.Write("Session " + i.ToString() + " is null");

}

else

{

LinkButton btn = new LinkButton();

btn.ID = "Modal-" + i.ToString();

btn.Text = "Show Room " + i.ToString();

btn.Click += (sender, e) => ShowPopUp(sender, e, i, ph);

DataTable table = (DataTable)HttpContext.Current.Session[i]; // Get the data table.

Label lbl = new Label();

lbl.ID = "Room-" + i.ToString();

lbl.Text = "Room " + i.ToString();

Label lblBreak = new Label();

lblBreak.ID = "Label-Break" + i.ToString();

lblBreak.Text = "<br/>";

ph.Controls.Add(lbl);

ph.Controls.Add(lblBreak);

ph.Controls.Add(btn);

ph.Controls.Add(lblBreak);

foreach (DataRow row in table.Rows) // Loop over the rows.

{

foreach (var item in row.ItemArray) // Loop over the items.

{

Label lblValue = new Label();

lblValue.ID = "Label-Value-" + item.ToString();

lblValue.Text = item.ToString();

Label lblBreak2 = new Label();

lblBreak2.ID = "Label-Break" + i.ToString();

lblBreak2.Text = "<br/>";

ph.Controls.Add(lblValue);

ph.Controls.Add(lblBreak2);

}

Any help is very much appreciated.

[Solved] Resource mapping with Exchange

Hi,

I have added a RadScheduler to my page, which loads several calendars from exchange. To realize that I used your Live Demo/Exchange example. Until now, this works fine.

As the calendars I'm reading from are meeting rooms, I would like to view them as resources. In another thread I have read the following: The mailboxes can be mapped to RadScheduler resources in the CreateAppointmentsFromCalendarItem method. You should inspect the mailbox of the calendar item and assign a corresponding resource.

I had a look in the code, but I don't seem to get this working. Does someone have a working example for this? I can't imagine that I'm the only one who wants to realize something like this.

Many thanks in advance!
