Dynamic group

hi

based on the example you have http://demos.telerik.com/aspnet-ajax/scheduler/examples/resourceheadertemplates/defaultvb.aspx
where your 4 speakers has static settings in the resource style and mapping.

I am having an eviromment where my speakers are very dynamic. we engage many different speakers on an assignment basis and we insert speaker as we engage them and delete them when don't require their speaking engagement.

Grouping is done vertically and we uses Timeline to display speakers on the left without displaying time.

How do i go about it doing dynamically?

Thanks

calendarView.set_selectedDate(eventArgs.get_appointment().get_start());

Determine Column ID of Filtered Column

Hello,

I'm using filtering on my grid. When the user selects a filter the "Item_Command" event is triggered where I can retrieve the Filter pair from the command argument. From this argument I can get the "filterPair.first", "filterPair.second", ..etc. Using this approach I can get access to the column name that the user is filtering, but I need the associated Column ID. Is it possible to associate more data with this filter or command argument? Maybe I could add an attribute to the filter Textbox when the filter is created, then read it on ItemCommand?

Please let me know if you have suggestions on the best approach.

protected void grdSummary_ItemCommand(object source, GridCommandEventArgs e)

{

if (e.CommandName == RadGrid.FilterCommandName)

{

Pair filterPair = (Pair)e.CommandArgument;

string strOperator = filterPair.First; // Starts With, ..etc

string strColumn = filterPair.Second; // Column Filtering On

string searchValue = ((TextBox)(e.Item as GridFilteringItem)[filterPair.Second.ToString()].Controls[0]).Text;

           string columnId = ??

RadAjaxManager doesn't execute second request

I have a simple test project.

One panel executes a timer every 4 seconds (a long running task).

Another panel has a button that will redirect to another page.

Each panel is added to the radajaxmanager ajaxsettings

When the timer is executing, the button on the second panel never executes (although the loading panel is shown). So the new page isn't shown.

This is the code I use:

protected void Page_Load(object sender, EventArgs e)

{

RadAjaxManager1.RequestQueueSize = 3;

// Panel 1

Panel panel = new Panel();

panel.Height = 200;

panel.Width = 200;

panel.BorderColor = System.Drawing.Color.Green;

panel.BorderWidth = 3;

panel.BorderStyle = BorderStyle.Solid;

panel.ID = "NewPanel";

Label newLabel = new Label();

newLabel.ID = "NewLabel";

panel.Controls.Add(newLabel);

Timer newTimer = new Timer();

newTimer.ID = "newTimer";

newTimer.Interval = 4000;

newTimer.Enabled = true;

newTimer.Tick += newTimer_Tick;

panel.Controls.Add(newTimer);

RadButton newButton = new RadButton();

newButton.ID = "newButton";

newButton.Click += newButton_Click;

panel.Controls.Add(newButton);

form1.Controls.Add(panel);

// Panel 2

Panel panel2 = new Panel();

panel2.Height = 200;

panel2.Width = 200;

panel2.BorderColor = System.Drawing.Color.Beige;

panel2.BorderWidth = 3;

panel2.BorderStyle = BorderStyle.Solid;

panel2.ID = "NewPanel2";

Label newLabel2 = new Label();

newLabel2.ID = "NewLabel2";

panel2.Controls.Add(newLabel2);

RadButton newButton2 = new RadButton();

newButton2.ID = "newButton2";

newButton2.Click += newButton2_Click;

panel2.Controls.Add(newButton2);

form1.Controls.Add(panel2);

RadAjaxManager1.AjaxSettings.AddAjaxSetting(panel, panel);

RadAjaxManager1.AjaxSettings.AddAjaxSetting(panel2, panel2);

}

void newButton2_Click(object sender, EventArgs e)

{

System.Threading.Thread.Sleep(500);

this.Page.Response.Redirect("~/Test.aspx");

}

void newButton_Click(object sender, EventArgs e)

{

System.Threading.Thread.Sleep(500);

Label lbl = Page.FindControl("NewLabel") as Label;

lbl.Text = System.DateTime.Now.ToString();

}

void newTimer_Tick(object sender, EventArgs e)

{

System.Threading.Thread.Sleep(3000);

Label lbl = Page.FindControl("NewLabel") as Label;

lbl.Text = System.DateTime.Now.ToString();

}

RadAjaxLoadingPanel

Hi guys,
I have following code in aspx:

<

telerik:RadScriptManager ID="ScriptManager1" runat="server" />

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">

<telerik:AjaxSetting AjaxControlID="mainPanel">

<telerik:AjaxUpdatedControl ControlID="mainPanel" LoadingPanelID="RadAjaxLoadingPanel1" />

</UpdatedControls>

</telerik:AjaxSetting>

</AjaxSettings>

</telerik:RadAjaxManager>

<telerik:RadAjaxLoadingPanel ID="RadAjaxLoadingPanel1" EnableSkinTransparency ="true" runat="server">

</telerik:RadAjaxLoadingPanel>

I have following code in c#:

protected

void Button_Click(object sender, EventArgs e)

{

string reqno = string.Empty;

string status = string.Empty;

string fyear = FYear.ToString();

SecureQueryString param = new SecureQueryString();

param.Add(

"ReqnoId", reqno);

param.Add(

"StatusId", status);

param.Add(

"Fyear", fyear);

string url = "~/PerSession/PRRequest/PrincipalRequest.aspx?data=" + param.ToString();

Response.Redirect(url);

}

In VS2005 it works fine.When I converted to VS2010 and try to click on button above to redirect I am gettig this error:
Microsoft JScript runtime error: Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(), response filters, HttpModules, or server trace is enabled.
Details: Error parsing near '�'.

When I comment out this code:

<telerik:AjaxUpdatedControl ControlID="mainPanel" LoadingPanelID="RadAjaxLoadingPanel1" />

</UpdatedControls>

it works fine but progress bar now does not working.
Please help me to resolve this issue.

Creating multilevel Hierarchy grid in codebehind

Hi there everyone........Im trying to create a grid with dynamic hierarchy drill down levels in code behind....this is my code

SqlConnection cn = new SqlConnection(connStr);

SqlDataAdapter da = new SqlDataAdapter("SELECT MAX(node) AS node FROM tabs", cn);

DataTable dt = new DataTable();

if (cn.State == ConnectionState.Closed)

{

cn.Open();

}

try

{

da.Fill(dt);

}

catch { }

if (dt != null && dt.Rows.Count > 0)

{

Int32 node = Convert.ToInt32(dt.Rows[0]["node"].ToString());

RadGrid RadGrid1 = new RadGrid();

SqlDataSource sdsMaster = new SqlDataSource(connStr,"SELECT * FROM tabs WHERE active=1 AND idParentNode = '0' ORDER BY displayOrder");

sdsMaster.ID = "sqlDataSourceMaster";

phGridContainer.Controls.Add(sdsMaster);

RadGrid1.ID = "RadGrid1";

RadGrid1.DataSourceID = "SqlDataSourceMaster";

RadGrid1.MasterTableView.DataKeyNames = new string[] { "id" };

RadGrid1.Width = Unit.Percentage(98);

RadGrid1.PageSize = 3;

RadGrid1.AllowPaging = true;

RadGrid1.AllowSorting = true;

RadGrid1.PagerStyle.Mode = GridPagerMode.NextPrevAndNumeric;

RadGrid1.AutoGenerateColumns = false;

RadGrid1.ShowStatusBar = true;

RadGrid1.MasterTableView.PageSize = 10;

//Add columns

GridBoundColumn boundColumn;

boundColumn = new GridBoundColumn();

boundColumn.DataField = "id";

boundColumn.HeaderText = "ID";

RadGrid1.MasterTableView.Columns.Add(boundColumn);

boundColumn = new GridBoundColumn();

boundColumn.DataField = "label";

boundColumn.HeaderText = "Tab";

RadGrid1.MasterTableView.Columns.Add(boundColumn);

if (node > 0)

{

for (int i = 1; i <= node; i++)

{

SqlDataSource sds = new SqlDataSource(connStr,"SELECT * FROM Tabs WHERE active=1 AND idParentNode = @id ORDER BY displayOrder");

/*THIS IS THE PART IM HAVING ISSUES*/

sds.SelectParameters.Add("id", RadGrid1.MasterTableView.DataKeyValues[0].ToString());

sds.ID = "sqlDataSource" + i.ToString();

phGridContainer.Controls.Add(sds);

GridTableView tableViewDetail = new GridTableView(RadGrid1);

tableViewDetail.DataSourceID = "sqlDataSource" + i.ToString();

tableViewDetail.Width = Unit.Percentage(100);

tableViewDetail.DataKeyNames = new string[] { "id" };

GridRelationFields relationFields = new GridRelationFields();

relationFields.MasterKeyField = "id";

relationFields.DetailKeyField = "idParentNode";

tableViewDetail.ParentTableRelation.Add(relationFields);

RadGrid1.MasterTableView.DetailTables.Add(tableViewDetail);

//Add columns

boundColumn = new GridBoundColumn();

boundColumn.DataField = "id";

boundColumn.HeaderText = "ID";

tableViewDetail.Columns.Add(boundColumn);

boundColumn = new GridBoundColumn();

boundColumn.DataField = "label";

boundColumn.HeaderText = "Tab";

tableViewDetail.Columns.Add(boundColumn);

}

phGridContainer.Controls.Add(RadGrid1);

}

cn.Close();

How can i get the Parent datakey to be able to insert that parameter within my dynamically generated sqldatasource.....Is it possible to have this done using radgrid control?? I know i can use the Tree View control but I the requirements fit the rad grid one.

Thks in advance

Dynamic RadPageView

Hi, I am referring to this online demo for adding of usercontrols to radmultipage dynamically.
http://demos.telerik.com/aspnet-ajax/tabstrip/examples/applicationscenarios/dynamicpageview/defaultcs.aspx

here the control path is saved in radpageview id property, but in my case control path could be long, so I don't want to save it in ID field. Is there any other property I can use.

I tried using Attribute collection, but I am getting that collection as empty in

RadMultiPage1_PageViewCreated

Skin Update Failed

I have been trying to use the Visual Style Builder for the last 2 days to no avail. I build a new skin called "TEST", select Grid, and base it on the "Vista" skin. Any changes I make using the Colorize functionality works as expected, and saves the skin fine. The downloaded file works in any projects I use it in. However, if I try to fine tune the skin any changes I make cannot be saved. I get a pop up message that says (also see attached screenshot):

"Skin Update Failed! A server error has occurred. We have been notified and will try to resolve it ASAP. Sorry for the inconvenience."

I have reproduced this on the most recent versions of Firefox, Chrome, Safari, and IE9. BTW, IE9 doesn't give me the option to remove images or indicate that any are being used.

Since I hadn't seen a post on this, I figured I'd mention it...
