Steps:

1. Go to Telerik Web UI MultiColumnComboBox WebForms MultiColumnComboBox Overview Demo | Telerik UI for ASP.NET AJAX

2. Enter "ha" select some records

3. Click out of the dropdown to close it

4. Textbox keeps "ha" but the message below reads that You have selected Thomas Hardy whose ID is AROUT. They are a Sales Representative at Around the Horn however, nothing has been selected.

Is it expected ?
If it's a bug and having a long cycle to fixing bugs could you recommend any workaround?

Hi, I have a Timeline view RadScheduler, and I would like to access some of the cells based on resource name and time slot.
Please see the image for reference.
I searched forums and most questions are about how to set the background color of time slots, and I checked documentation the time slot represents the whole row/column of a specific time for all resources. But in my case I only want to set the time slot of specified resource, aka a single cell or coulple of cells.
Could anyone help me?

Hi All!

I am using custom filter for my RadGrid (I wouldn't post the code here anymore) but my problem is, everything is working fine, but when I change page on the radGrid, it doesn't show anything , but when I click the filter button again it displays the results again 

I tried putting this on my code: 
      protected void RadGrid1_PageIndexChanged(object sender, GridPageChangedEventArgs e)
        {
            RadGrid1.CurrentPageIndex = e.NewPageIndex;
            DBcontrols.filterRadGrid();
            DBcontrols.filterRadGridUsingRange();
            RadGrid1.DataBind();
        }


still No avail, how do I retain the Databind even when changing pages?

I am using a RadTextBox for a simple messaging form, and if the user leaves a field blank, I use a CustomValidator to set the control IsValid=true.  This is great and it uses the invalid style (pink background) and little icon and brings the user's attention to the field.

protected void valMissingFields_ServerValidate(object source, ServerValidateEventArgs args)
{
    txtMessageSubject.Text = txtMessageSubject.Text.Trim();
    txtMessageBody.Text = txtMessageBody.Text.Trim();

    txtMessageSubject.Invalid = (txtMessageSubject.Text == "");
    txtMessageBody.Invalid = (txtMessageBody.Text == "");

    args.IsValid = (!txtMessageSubject.Invalid && !txtMessageBody.Invalid);
}

I thought the InvalidStyleDuration would make it go away after a few seconds (3000 ms = 3 seconds):

<table cellspacing="0" cellpadding="0" style="width:100%;">
    <tr valign="top">
        <td style="width:90px;">
            Message:
        </td>
        <td>
            <telerik:RadTextBox ID="txtMessageBody" runat="server" 
                Width="100%" MaxLength="1000" TextMode="MultiLine" Rows="25" 
                InvalidStyleDuration="3000" 
                EnableEmbeddedSkins="false" Skin="MyCustomSkin"></telerik:RadTextBox><br />
        </td>
        <td style="width:20px; text-align:right;">
            <span class="required">*</span>
        </td>
    </tr>
</table>

But it does not.

Instead, the user is stuck typing into the text box with bright red bold lettering.  

Am I misunderstanding how this works?

As a workaround, I thought I'd use the OnClientEvents for OnValueChanging to make it switch the Invalid indication off, but apparently that event only fires when focus moves away from the control.

I'm using the RadSpreadsheet component and saving it's content following this instructions here:

Telerik RadControls Access the Spreadsheet workbook on the server - Telerik UI for ASP.NET AJAX

 

So, my code behind is like this:

protected void Page_Load(object sender, EventArgs e)
{
    if (Page.IsCallback && Request.Params["__CALLBACKID"] == RadSpreadsheet1.UniqueID)
    {
        Workbook workbook = Telerik.Web.Spreadsheet.Workbook.FromJson(Request.Params["__CALLBACKPARAM"]);
        SaveWorkBook(workbook);
    }

}

 

With this code I'm able to save the spreadsheet just fine. But it's not saving the images I add using the Insert Image button (from telerik component). The images are simply not being passed through.

How can I work around that? Thank you!

I inherited a .NET website using RadAjax.Net2.dlls. Currently only supported in IE compatibility mode from my understanding.  I would like to upgrade to a version that works in current browsers.  The website is using .NET 2.0 but we are upgrading the framework to 2.8 if possible.   I appreciate any recommendations on upgrade path.

Greetings,

I am currently working on an ASP.NET WebForms application, which uses a Telerik RadTreeView.

The treeview uses has the tri state checkboxes active and gets populated server side. We first create a tree of stations (around 2500), which can contain other stations. After that, we populate the tree with datapoints by iterating over all stations and adding the datapoints with the Node.Add() Method.

So the structure is as follows:

Station
- Station 1
- Station 2
   - Station 4
      - DataPoint
      - DataPoint
   - Station 5

The checkboxes are used to show if any datapoint is already selected in the treeview and to select additional datapoints for a grouping.
There are multiple groups which can be switched between to see a different selection in the tree.

Therefore, it is necessary to add every datapoint that was already selected (and saved) to show the tri-state checkboxes correctly on page load.
After that a load on demand is possible.

What I tried so far:

  • Loading the stations and inserting the datapoints (20k objects) before adding the root node to the RadTreeView
    • Building the station tree is fast, but adding the root node to the RadTreeView Control takes about 600 seconds
  • Loading the stations and inserting the datapoints (20k objects) after adding the root node to the RadTreeView

    • Building the station tree is fast, but addings the nodes the the RadTreeView Control takes a long time

  • Loading the stations and adding the minimal amount of datapoints to display everything checked correctly with tri state checkboxes
    • Building the station tree is fast, but on every change of the grouping the tree will be walked completly to attach datapoints which were selected in the new grouping but where not present from the older groupings (or loaded on demand)

So my question is, is there a faster way to load about 20k objects into the tree, so on the change of grouping no new datapoints need to be loaded?

Or am I thinking this very wrong currently? Thank you in advance!

Hi, my grid has many columns and some of them have very long header texts.

I already set <Resizing AllowColumnResize="true" AllowResizeToFit="true" ResizeGridOnColumnResize="true"  />

However the header text are still clipped.

I would like to set the long header text to be shown as whole instead of clipped.

Please help! Thanks!
