RadTextBox not giving text

Hi all,
I've got a problem with radtextbox in my page. If I use javascript to insert text in a RadTextBox I can do it easily and it works well, but if I try to access thata text server-side, radtextbox.text property is ALWAYS empty, even if I type into it, not only if I set it using Javascript.

My text box is defined as follow
<telerik:RadTextBox TextMode="MultiLine" runat="server" ID="txtNote" MaxLength="512" Rows="5" Width="100%" />

Kind regards
Riccardo

Install into GAC on Server 2008 r2?

Hi,

I have been unsuccessful in my attempts to install Telerik.Web.ui.dll into the GAC on our Win 2008 server r2. I have tried everything from drag drop to windows\assembly (doesn't show an error, doesn't install) to gacutil from 2.0 sdk (error with telerik assy being greater than current assembly) to gacutil 4.0 from VS 2010 tools. I am running my sites under .NET 4.0 and have set all application pools to use .NET 4.0.

Is there any way to do this other than placing the telerik.web.ui.dll in each bin folder for each app?

Thanks!

Using a ValidationSummar in a RadToolTip

Hello,
I would like to use a RadToolTip to add, modify items from a RadGrid.
It works well but when I add to the radtooltip a RequiredFieldValidator and ValidationSummary, the radtooltip doesn't work.

Could you help me ?

Here are the javascript an HTML:

<

telerik:RadCodeBlock ID="RadCodeBlock1" runat="server">

function

CloseToolTip()

{

var tooltip = Telerik.Web.UI.RadToolTip.getCurrent();

if(tooltip)

{ tooltip.hide(); };

}

function

OkToolTip()

{

CloseToolTip();

ajaxManager.ajaxRequest(

"RT_LOT");

}

</

script>

</

telerik:RadCodeBlock>

<

telerik:RadToolTip ID="RT_LOT" runat="server" HideEvent="FromCode" Modal="True"

Position="Center" RelativeTo="BrowserWindow" ShowCallout="False">

<br />

<tr>

<td><asp:Label ID="RT_LOT_LibLabel" runat="server"></asp:Label></td>
<td><asp:RequiredFieldValidator ID="RT_LOT_RFV" runat="server" Display="Dynamic" ErrorMessage="Erreur"

ControlToValidate="RT_LOT_Lib" SetFocusOnError="True">*</asp:RequiredFieldValidator></td>

</tr>

<tr>

</tr>

<tr>

<td><input id="RT_LOT_Ok" runat="server" type="button" value="Ok" onclick="OkToolTip();"

style="width: 80px; color: #008000; font-weight: bold;" /></td>

<td><input id="RT_LOT_AnnBt" type="button" value="Annuler" onclick="CloseToolTip();"

style="width: 80px; color: #FF0000; font-weight: bold;" /></td>

</tr>

</table>

</telerik:RadToolTip>

Here is the code behind:
// Ajaxifying

protected

void Page_Load(object sender, EventArgs e)

{

try

{

radAjaxManager.AjaxRequest += new RadAjaxControl.AjaxRequestDelegate(manager_AjaxRequest);

radAjaxManager.AjaxSettings.AddAjaxSetting(toolBar, RT_LOT);
}

catch (Exception err)

{...

}

// open the RadToolTip from a toolbar:

protected

void toolBar_ButtonClick(object sender, RadToolBarEventArgs e)

{

try

{

switch (e.Item.Value)

{

case @"CRT":
...

RT_LOT.Show();

break;

}

catch (Exception err)

{...

}

}
// get the data from the RadToolTip

protected

void manager_AjaxRequest(object sender, Telerik.Web.UI.AjaxRequestEventArgs e)

{

try

{

if (e.Argument == @"RT_LOT")

{

... };

}

catch (Exception err)

{ ...

}

Many thanks...
Bernard

People consitently pick on every expand link just to see no data associated with it, can this be changed to be hidden.

Passing Extra Parameters to Web Method from ClientSettings DataBinding

Is it possible to pass parameters other than row index, max rows, filter, and sort to the Web Method? I can't seem to find any examples. I have a RadGrid successfully using a Web Service to do client-side data binding, but I need it to pass in some extra parameters.

I'm thinking that I *might* be able to do this by passing the other parameters as part of the filter parameters and then handling that in the Web Service, but that just seems like a hack. :-)

IgnorePaging=true not working on expot to excel

Hi there,

I export the radgrid to excel. Using the following code...
<ExportSettings FileName="Program_Accounts" OpenInNewWindow="true" IgnorePaging="true"></ExportSettings>

RadGrid1.ExportSettings.ExportOnlyData = true;
RadGrid1.ExportSettings.IgnorePaging = true;
RadGrid1.ExportSettings.OpenInNewWindow = true;

This RadGrid1.ExportSettings.IgnorePaging = true is not exporting all the pages to excel. i can't figure out why?. While binding the grid all the records gets binded.

Is there any scenario only first page alone will be exported even after specifing IgnorePaging = true on design and codebehind

Please help me why after giving IgnorePaging = true its not exporting all the records in the grid.

Thanks!.
