Check all items on pageload

Hi

I tried to check all items on pageload. I used below source code.

for (int i = 0; i < objList.Count; i++)

{

cboLocation.Items.Add(new RadComboBoxItem(objList[i].Name, objList[i].ID));

cboLocation.Items[i].Checked = true;

}

It worked and show "All Items Checked" text on local. But when I publish to server, it did not show "All Items Checked" text and display items with "," delimiter. Can anyone advice me on this?

Thank you.

Best regards,

Ei Wai

Get value from sql database and bind to binary image..

I have a table in sql server with a field called imageData type is nvarbinary(max)

I have a binary image in a radwindow.

I use the radAsyncUploader to save the image in the database.

Once the image is saved, I want to display the image to the user next to the radAsyncUploader tool (right side).

I try setting the DataValue property of the binaryImage control but that does not seem to work.. Any ideas?

protected void LinkButtonSaveImage_Click(object sender, EventArgs e)

{

//Handle Uploaded images

if (!Object.Equals(Context.Cache.Get(Session.SessionID + "UploadedFile"), null))

{

var fileType = this.AsyncUpload1.UploadedFiles[0].ContentType;

User user = (User)Session["currentUser"];

AttachmentRepository attachmentRepo = new AttachmentRepository();

Stream fileStream = ((MemoryStream)Context.Cache.Remove(Session.SessionID + "UploadedFile"));

byte[] attachmentBytes = new byte[fileStream.Length];

fileStream.Read(attachmentBytes, 0, Convert.ToInt32(fileStream.Length));

var attachmentService = new AttachmentService(attachmentRepo, user);

attachmentService.SetAttachment(attachmentBytes, fileStream, fileType);

RadBinaryImage1.DataValue = attachmentBytes;

}

How to Shift the Ticks on an ItemSlider to line up with the slider Text?

I have an RadSlider (ItemSlider):

<telerik:RadSlider ID="RadSlider1" runat="server" ItemType="item" Width="325px"
Height="45px" AnimationDuration="400" CssClass="ItemSlider"
ThumbsInteractionMode="Free" TrackPosition="BottomRight" Value="5" >
<Items>
<telerik:RadSliderItem Text="1" Value="1"></telerik:RadSliderItem>
<telerik:RadSliderItem Text="2" Value="2"></telerik:RadSliderItem>
<telerik:RadSliderItem Text="3" Value="3"></telerik:RadSliderItem>
<telerik:RadSliderItem Text="4" Value="4"></telerik:RadSliderItem>
<telerik:RadSliderItem Text="5" Value="5"></telerik:RadSliderItem>
<telerik:RadSliderItem Text="6" Value="6"></telerik:RadSliderItem>
<telerik:RadSliderItem Text="7" Value="7"></telerik:RadSliderItem>
<telerik:RadSliderItem Text="8" Value="8"></telerik:RadSliderItem>

<telerik:RadSliderItem Text="10" Value="10"></telerik:RadSliderItem>
</Items>
</telerik:RadSlider>

How do I shift the "ticks" so that they line up exactly with the "Text"?

Requirements: I need the ability to click and have the slide go to my click position. I also need tick marks that line up with the slider Text.

Return footer text from web service

I would like to fill in some custom footer information after search results are returned from a web service. In the RadComboBox it was as easy as setting the RadcomboBoxData.Message property - how does one go about doing it for a SearchBox? I would like to display either the number of items found + total search time, or a message saying "Please enter 3 characters to search".

One possible solution is to return only 1 item with the message to display, and a null value; then upon client items requesting has ended look through the results in javascript, remove it if it fits the critieria and set the footer - but I don't even see any client events for when the search results are received.

Thank you in advance,
John

DropDownList does not trigger selectedIndexChanged on postback

I have a telerik DDL like so:

<telerik:RadDropDownList ID="rddlNames" runat="server" DataSourceID="NamesDataSource" DataTextField="Name" DataValueField="ID"

OnSelectedIndexChanged="rddlNames_SelectedIndexChanged" OnDataBound="rddlNames_DataBound" AutoPostBack="True" CausesValidation="false"></

telerik:RadDropDownList>



protected void rddlNames_SelectedIndexChanged(object sender, Telerik.Web.UI.DropDownListEventArgs e)
        {
            radTileList.Visible = true;
            radTileK.NavigateUrl = "KSignOut.aspx?DC=" + rddlNames.SelectedItem.Text;
            radTileT.NavigateUrl = "TSignOut.aspx?DC=" + rddlNames.SelectedItem.Text;
            radTileManageT.NavigateUrl = "ManageT.aspx?DC=" + rddlNames.SelectedItem.Text;
            radTileManageK.NavigateUrl = "ManageK.aspx?DC=" + rddlNames.SelectedItem.Text;
            radTileManageR.NavigateUrl = "ManageR.aspx?DC=" + rddlNames.SelectedItem.Text;
        }
 
        protected void rddlNames_DataBound(object sender, EventArgs e)
        {
            rddl.Items.Insert(0,new Telerik.Web.UI.DropDownListItem("---"));
                rddlNames.Items[0].Enabled = false;// Attributes.Add("disabled", "disabled");
            rddlNames.Items[0].Selected = true;
        }

There is one major issue with it in that the selectedIndexChanged doesn't trigger when navigating to the root of the website i.e. http://locahost:1234

But if I navigate to http://localhost:1234/Default it works fine.

This is causing huge confusion among the users which keep reporting the website as not working.

Please suggest a fix for this as it is quite urgent.

Thank you.

can't change 'task' title for editing a task popup

when you double click on a task in the gantt chart, it's easy enough to change the contents of the editor popup that comes up using the gantt's editable => template feature. This does not allow you to change the title though, which still says 'task' at the top. Where can you change that?

RadWindow Loading Panel

Greetings,

I have applied a site-wide skin in my web.config file like so:

I have specified a loading panel in my master page(s) like so:

<telerik:RadAjaxLoadingPanel runat="server" ID="MainLoadingPanel" CssClass="load-panel" IsSticky="true" Skin="Metro" />

Please note the difference in skins. My objective is to have all loading panels observe the Metro skin while all other controls side-wide observe the Default skin. As it currently stands, the Default skin is applied to the loading panel when opening a Rad Window. All other actions display the Metro loading panel as desired - it's only the loading panel that is visible when opening a Rad Window that fails. What am I doing wrong?

Many Thanks,

Paul
