Linq datasource parameters not working with Radgrid

Hi

I'm using rad grid and implemented parameters for insert,update and where.
But created parameters for update not updated the database. Insert and where parameters are working perfectly.

Please look at the code how I implemented in the project,

<asp:LinqDataSource ID="ldsDList" runat="server" <br> ContextTypeName="MDataContext" <br

>                        EnableDelete="True" EnableInsert="True" EnableUpdate="True" EntityTypeName="" <

br> TableName="DLists"><br> <InsertParameters><br> <asp:ControlParameter ControlID="HFUser" Name="EnteredBy" <br> PropertyName="Value" Type="Int32" /><br> <asp:Parameter Name="DateEntered" Type="DateTime" /><br> </InsertParameters><br> <UpdateParameters><br> <asp:ControlParameter ControlID="HFUser" Name="ModifiedBy" <br> PropertyName="Value" Type="Int32" DbType="Int32" /><br> <asp:Parameter Name="DateModified" Type="DateTime" /><br> </UpdateParameters><br> </asp:LinqDataSource>

Protected Sub ldsDList_ContextCreating(sender As Object, e As System.Web.UI.WebControls.LinqDataSourceContextEventArgs) Handles ldsDList.ContextCreating<br> If e.Operation = DataSourceOperation.Insert Then<br> Me.ldsDList.InsertParameters("DateEntered").DefaultValue = DateTime.Now.ToString()<br> ElseIf e.Operation = DataSourceOperation.Update Then<br> Me.ldsDList.UpdateParameters("DateModified").DefaultValue = DateTime.Now.ToString()<br> End If<br> End Sub

Accessing Controls Inside Templates of ControlGroups or ContextualTabGroup

Hi members,
i am still new in testing telerik great controls and one of my favourites is the RibbonBar-Control.
I can follow the example "Find the RadComboBox server sde" at http://www.telerik.com/help/aspnet-ajax/ribbonbar-templates-accessing-controls-server-side.html, but dont know, how to access controls, when they are
a) in a RibbonBarContextualTabGroup
or
b) in a RibbonBarControlGroup

The solution (as described in the upper link) with:

Dim tab2 As RibbonBarTab = RadRibbonBar1.FindTabByValue("Tab2")
Dim combobox1 As RadComboBox = DirectCast(tab2.Groups(0).Items(0).FindControl("RadComboBox1"), RadComboBox)

doesn't work, when the control is in a RibbonBarContextualTabGroup or RibbonBarControlGroup.

Thanks for any help!!!

Related ComboBox controls - Url issue

Hi,

I have two related combobox controls . The second combobox (disabled by default) becomes enabled by selecting an item in the first combobox.
By selecting an item in the first control, the sencond one become enabled and a TEXT is added to the URL (View attached screen-shot). What is that? and how can I hide it (always). I mean, I don't need that the URL be affected by the web controls.

Regards,

Exponential Javascript execution when loading grid with NumericColumns in Edit Mode

Hi,

we have a Grid with a couple of GridNumericColumns.
We want to load all rows in this Grid in edit mode when the page loads.

With about 50 items in the grid, the page loads relatively fast without about 1 seconds of Javascript execution measured in the Internet Explorer Developer Toolbar.

With 150 items there is noticeable lag in the browser after the items are displayed. Dev Toolbar profiler registers about 6 seconds of Javascript execution.

Wotj 250 items loaded the browser hangs on load, we get a long loading Javascript warning from Internet Explorer, and the profiler shows about 20 seconds of Javascript execution.

When removing the GridNumericColumns and replacing them with regular GridBoundColumns the rendering is blazing fast again (Profiler registers < 50ms of Javascript exeuction).

Here is sample code for you to reproduce the issue:

<telerik:RadScriptManager runat="server" ID="sm1">

</telerik:RadScriptManager>

<telerik:RadTextBox ID="itemcount" Label="ItemCount" runat="server"></telerik:RadTextBox>

<asp:Button runat="server" OnClick="OnClick" Text="Reload"/>

Org Chart Load On Demand

Hi,

I am trying to implement the load on demand functionality in Org Chart control.
From what I understand from the link1 and link2 is that the whole data (including the data which has already been rendered) needs to be rebound to the control each time a node is expanded. Please correct me if my understanding is wrong. If not, is it possible to implement it in such a way that if a node is expanded, only the children of that node needs to be fetched and bound to the control.
My primary objective is to bind a huge data set to the orgchart control without affecting the performance.
Thanks!

<telerik:RadButton runat="server" ID="btnResetInteriourFrontViewPhoto" AutoPostBack="False" OnClientClicked="interiourFrontViewPhotoClearImage"></telerik:RadButton>

</div>

On the client side I have the following Javascript:

function onLeftPhotoUploaded(sender, args) {

$find("<%=radAjaxManager.ClientID %>").ajaxRequest();

$telerik.$(".invalidLeftPhoto").html("");

$telerik.$("#lblLeftPhotoViewRequired").html("");

setTimeout(function () {

sender.deleteFileInputAt(0);

}, 10);

}

function onLeftPhotoValidationFailed(sender, args) {

$telerik.$('.invalidLeftPhoto').html('<%= MasterController.GetLabelValue("text.fileTooBig") %>').addClass("error");

sender.deleteFileInputAt(0);

}

function onRightPhotoUploaded(sender, args) {

$find("<%=radAjaxManager.ClientID %>").ajaxRequest();

$telerik.$(".invalidRightPhoto").html("");

$telerik.$("#lblRightPhotoViewRequired").html("");

setTimeout(function () {

console.log(sender._uploadedFiles.length);

sender.deleteFileInputAt(0);

}, 10);

}

function onRightPhotoValidationFailed(sender, args) {

$telerik.$('.invalidRightPhoto').html('<%= MasterController.GetLabelValue("text.fileTooBig") %>').addClass("error");

sender.deleteFileInputAt(0);

}

On the server side I have the following code:

protected void LeftViewPhotoFileUploaded(object sender, FileUploadedEventArgs e)

{

string path = Path.Combine(ConfigurationManager.AppSettings["SaveLocation"], PartnerId.ToString(), CarId.ToString(), ConfigurationManager.AppSettings["GeneralPictureLocation"]);

e.File.SaveAs(Path.Combine(path, "linkerflank.png"));

byte[] array = CreateThumbnail(path, "linkerflank.png");

leftViewPhoto.DataValue = array;

}

protected void RightViewPhotoFileUploaded(object sender, FileUploadedEventArgs e)

{

string path = Path.Combine(ConfigurationManager.AppSettings["SaveLocation"], PartnerId.ToString(), CarId.ToString(), ConfigurationManager.AppSettings["GeneralPictureLocation"]);

e.File.SaveAs(Path.Combine(path, "rechterflank.png"));

byte[] array = CreateThumbnail(path, "rechterflank.png");

rightViewPhoto.DataValue = array;

}

The problem is that when I delete an existing photo from an area, and then upload another photo to another area , the "old" photo is also rendered.I suppose that I can fix this with some cache settings on to the control.Can you help me with this bug?

Thank you.
