[Solved] Masterpage and content page ScriptManager

Hello, I have a Master page with a ScriptManager for my RadPanel and in my content page I need a ScriptManager for my RadToolTipManager. But when I do that I have a error telling that I can only have one ScriptManager. So if I remove my ScriptManager in my content page, it's telling me that the RadToolTipManager need a ScriptManager to work. Is there a solution to my problem.

Thanks

Issue With Telerik Input Controls

Hello,

I have a shared user control. This UC is in one page and everything works fine. In the second page, the RadTextBox client-API get_value() method reports "", when it has a legitimate value. There is very little javascript on that page, and it's not targeting textboxes; it's in a page with 6 tabs. The controls work fine; I have RadCombo's and the drop downs work as you would expect. But no text, no selected value, nothing is being reported (I have a script to check if the page is an empty form). How do I even debug this to figure out what is going on, and why the value isn't being reported?

Thanks.

GridSettingPersister doesn't work correctly

Hello,
in my web application I have a problem using GridSettingsPersister. In the applcation I have different RadGrid and I want let the user modify them (move columns, change column order/visibility/size). So i followed the instruction at http://demos.telerik.com/aspnet-ajax/grid/examples/programming/savinggridsettingsonperuserbasis/defaultcs.aspx.

I want the user to access a single page where he can choose which RadGrid to modify. After he choses the RadGrid, the application loads the chosen view grid into a panel and let the user modify it. After that we can save the configuration string in database.

I've used the GridSettingsPersister class of the example.

My problem is this:
- I choose the radgrid and load the radgrid to modify into the panel
- I modify some column visibility (show only 3 columns for example)
- I correctly save the settings into db
- I load the configuration from database string (here all works fine)
- I add visibility to another column and retry to save
- Now I load the settings from the database string instead of havinf 4 columns I see all columns of grid (it seems a wrong configuration string has been saved into database)

I use the following code to:
-load configuration

public static void LoadGridConfiguration(RadGrid pRdg, long pIdGruppoUtente, bool loadDefaultString = false)

{

GridSettingsPersister gsp = new GridSettingsPersister(pRdg);

using (DMWEntities context = new DMWEntities())

{

long idControlloAspx = (from ctrl in context.ControlliAspx

where (ctrl.NomeControllo == pRdg.ID)

select ctrl.IdControlloAspx).SingleOrDefault();

if (idControlloAspx == 0)

{

throw new Exception("Grid Control not defined in database [ControlliAspx]");

}

var stringaConfigurazioneGruppoUtente = (from pg in context.ProprietaGriglie

where (pg.IdControlloAspx == idControlloAspx) && (pg.IdGruppoUtente == pIdGruppoUtente)

select new { pg.StringaConfigurazione, pg.StringaConfigurazioneDefault }).FirstOrDefault();

if (loadDefaultString)

{

gsp.LoadSettings(stringaConfigurazioneGruppoUtente.StringaConfigurazioneDefault);

}

else

{

gsp.LoadSettings(stringaConfigurazioneGruppoUtente.StringaConfigurazione);

}

-save configuration

protected void btnPersistConfiguration_Clicked(object sender, EventArgs e)

{

MachinaWeb.ServerControls.RadPageView paginaConComboIdGruppoUtente = (MachinaWeb.ServerControls.RadPageView)((System.Web.UI.Control)MachinaWeb.ServerControls.Utility.FindControlType((Control)sender,

typeof(MachinaWeb.ServerControls.RadPageView)));

MachinaWeb.ServerControls.RadGrid gridUC = (MachinaWeb.ServerControls.RadGrid)((System.Web.UI.Control)MachinaWeb.ServerControls.Utility.FindControlType((Control)sender,

typeof(MachinaWeb.ServerControls.RadGrid)));

long selectedGU = long.Parse( ((RadComboBox)paginaConComboIdGruppoUtente.FindControl("blccmbGruppoUtente")).SelectedValue );

//MessageBox.ShowTelerik(Page, this, "Configurazione salvata (Id Gruppo " + blccmbGruppoUtente.SelectedValue + ")");

string gridName = gridUC.ID;

using (DMWEntities context = new DMWEntities())

{

long idControlloAspx = (from ctrl in context.ControlliAspx

where (ctrl.NomeControllo == gridName)

select ctrl.IdControlloAspx).SingleOrDefault();

{

throw new Exception("Grid Control not defined in database [ControlliAspx]");

}

Radgrid checkbox problem

My problem is that when i move from radgrid page1 to page 2 DataBound event is not calling,where i have written my necessary code.

        protected void gdTools_DataBound(object sender, EventArgs e)
        {

            clsVehicleToolMaping vhcleToolMapping = new clsVehicleToolMaping();

           i have tried the databound event code in item_databound event but the problem is that

for (int k = 0; k < gdTools.Items.Count; k++)

when the control goes to the above code count is always shown as zero.so events are not happening that are inside the for loop

Performance issue in Dynamic page Binding

Hai

I need to bind lacs of record to a radgrid. Instead of binding all records in need data source at i am binding only 10 records to the first page. When the user clicks on pagination link, i fetch the next set of rows from db and bind it to the radgrid. I pass the row start and ending position as argument to the database. It will work fine if the record count is less.When i increase the data the performance is slow. How can i increase the speed.

In SP i create a temp table to select the top rows And from the temptable i get the last 10 rows that i required for the particular page.

Is there any way to select the row between the particular row number?

Thanks

Height incorrect when using OnClientLoad with RadAjaxManager

RESOLVED: See notes blow.

Dynamically adding a RadEditor to the page and then calling set_mode() in the OnClientLoad event causes RadEditor to render abnormally.

I've attached a screenshot of this behavior. Here is the code to reproduce the issue:

<%@ Page Language="VB" AutoEventWireup="false" CodeFile="Default.aspx.vb" Inherits="_Default" %>

<%@ Register Namespace="Telerik.Web.UI" Assembly="Telerik.Web.UI" TagPrefix="telerik" %>

<script runat="server" language="vbscript">

Protected Sub btn_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btn.Click

Dim div As New HtmlGenericControl("div")

div.Style("height") = "300px"

div.Style("border") = "1px solid #f00"

Dim edt As New RadEditor()

edt.Height = Unit.Pixel(300)

edt.OnClientLoad = "function(editor,args){ editor.set_mode(1); }"

div.Controls.Add(edt)

pnl.Controls.Add(div)

End Sub

</script>

Steps:
1. Click "Load Controls" button

Expected result:
RadEditor added to page with 300px height

Actual result:
RadEditor added to page with very large height

Notes:
Issue only occurs the first time "Load Controls" button is pressed. Subsequently pressing "Load Controls" will produce the expected results.

I was able to resolve this issue by adding a slight delay...

setTimeout(function() { editor.set_mode(1); }, 100);

Update on Grid with dropdown selected value

Hi together,

I have a little problem, i created a Grid with a SQL Data Source. In my Grid I display two Columns, the first is "ClassName from Table tblClass" and the second is "City" from tblCity. The selects are ok. Now if i update a row with this line

UpdateCommand="UPDATE [tblClass] SET [ClassName] = @ClassName, [FK_CityID] = 2 %> WHERE [PK_ClassID] = @original_PK_ClassID"

the Name will update with the text that i put in the textbox. But i don't know how i can tell to FK_CityID = "selected dropdown value"

In my Dropdown i have the Property ListValueField="PK_City_ID", so that means i have only to replace the fix ID that i have now with the selected dropdown value. But I have no idea how I can do it.

[Solved] Collapse after grouping

Dear Forum,

I have a RadGrid with drag-and-drop grouping enabled and a default top level grouping set. I'm using the Q1 2010 build with VS2008 and ASP.net 3.5 C#.

I collapsed all to the top level grouping using the example from
http://www.telerik.com/help/aspnet-ajax/grdcollapseallitemsongrouping.html

What I would like to do is to collapse all groups except for the last group the client selects each time the client drags and drops a new group to the group by bar.

Does anyone have an example of this or can anyone point me in the right direction.

Thank you,
Celeste

[Solved] Having trouble with ViewState and programatically added / removed columns

Hi!

I've been fiddling a bit with the new TreeList control, and manage to add some template columns dynamically.
It seems it's ok to remove a few and add more, but when I remove a lot and add less, I get an exception saying

Invalid column type: "TreeListTemplateColumn".

[Exception: Invalid column type: "TreeListTemplateColumn".]
   Telerik.Web.UI.RadTreeList.CreateColumnByType(String columnType) +184
   Telerik.Web.UI.TreeListColumnsCollection.System.Web.UI.IStateManager.LoadViewState(Object state) +350
   Telerik.Web.UI.RadTreeList.LoadViewState(Object savedState) +97
   System.Web.UI.Control.LoadViewStateRecursive(Object savedState) +183
   System.Web.UI.Control.LoadChildViewStateByIndex(ArrayList childState) +134
   System.Web.UI.Control.LoadViewStateRecursive(Object savedState) +221
   System.Web.UI.Control.LoadChildViewStateByIndex(ArrayList childState) +134
   System.Web.UI.Control.LoadViewStateRecursive(Object savedState) +221
   System.Web.UI.Page.LoadAllState() +312
   System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +1661

This also happens when "a lot" of columns has been added and I try to collapse a section.

I guess it's pretty easy to reproduce if you just fiddle a bit with the following page / code.
Try for instance to expand "A", then click "Month", and try to collapse "A".
Or just click "Month" then "Quarter".

[Solved] Win7 64 bit Javascript errors

Hi,

I upgrade my os WinXP to Win7 64 bit but when debug my web application gives some javascript errors. For example; I have to put my web page below this code for RadComboBox;

Telerik.Web.UI.RadComboBox.prototype._removeDropDown = function() {

var slide = this.get_dropDownElement().parentNode;

slide.parentNode.removeChild(slide);

if (this._disposeChildElements)

$telerik.disposeElement(slide);

if (!$telerik.isSafari)

slide.outerHTML = null;

this._dropDownElement = null;

};

But this code block is not run on RadTabstrip. When I click another tab which has no RadCombobox that gives an error. Also I get javascript errors in some pages redirecting. How to avoid this errors ?
