Need Help on RadComboBox Multi Checkbox Filtering Not Working

Hello Telerik Team,

I can't seem to make multiple checkbox filtering work on a RadComboBox inside a RadGrid using a Filter Template.

I have been working on the examples given on the thread below for several days already..

http://www.telerik.com/forums/how-to-persist-dropdownlist-selected-index-and-value-on-postback-from-radgrid-filtertemplate#GW3MyQLmVEmy8XzsmrHzeQ

Particularly, I used Eyup's sample solution of RadGridFilterComboClientAndServerDataBinding and modified the DataSource to have advance data binding, as I need to populate my RadComboBox in the code behind. But this sample code only supported single item filtering..

So I used the code coming from SearchMultipleValues.aspx and SearchMultipleValues.aspx.cs to implement the multi checkbox filtering. This code can be found on Eyup's post below, inside RadGridFilterMultipleChecked.zip:

http://www.telerik.com/support/code-library/multi-selection-radcombobox-for-filtering-grid#2351833

Please check my combined aspx code and code behind below.

I added a new column, "Quantity", which will be filtered using multi checkbox filtering. This is our focus which is not working.. This column is populated inside the GetGridSource(). Filter values are binded to the RadComboBox using RadComboBoxQuantity_DataBinding event, setting it to the same data source of the RadGrid. (I know I should bind distinct values here, but just for the purpose of an example I haven't updated the code yet.)

 

Selecting several items from the combobox and clicking ImageButton1, multi checkbox filtering does not work..

 

Note: I put Filter="Contains" in the RadComboBox property as I read somewhere here and in the documentation that this will enable the textfield in the combo box so the user can type, which I also need.

 

I am currently stuck using Telerik.Web.UI, Version=2012.3.1308.35. Would anyone know why the multi checkbox filtering does not work?

Any help is appreciated.. Thank you in advance.

Formatting with other styled controls

I am trying to have the AutoCompleteBox fit in with the other controls on my form.  Note that the textbox is not style similarly to the other textboxes.  Is there some technique to obtain consistency?  

<telerik:RadFormDecorator ID="RadFormDecorator1" runat="server" DecoratedControls="All" Skin="Web20" />
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox><br />
<asp:TextBox ID="TextBox2" runat="server"></asp:TextBox><br />
<telerik:RadAutoCompleteBox ID="RadAutoCompleteBox1" runat="server" Skin="Web20"></telerik:RadAutoCompleteBox><br />
<asp:TextBox ID="TextBox3" runat="server"></asp:TextBox><br />
<asp:TextBox ID="TextBox4" runat="server"></asp:TextBox>

 

The screenshot attached show first without the RadDecorator and then with (note that it does not make it better.

CODE:

I load a datatable (I did see the data in it) and then bind in a button event

grdReport.DataSource = dtReport;
grdReport.DataBind();

Session["Report"] = dtReport;
Session.Timeout = 30;

 

 protected void grdReport_PageIndexChanged(object sender, GridPageChangedEventArgs e)
        {
            //**********
            //pagination
            //**********
            DataTable dt = (DataTable)Session["Report"];
            grdReport.DataSource = dt;
            grdReport.Rebind(); // DataBind();  // note I have tried DataBind and Rebind here
        }

I get no grid when a page is selected.

Thanks for your help in advance.

Last Character in showing in Search on some machines

I'm having an issue where on some of the clients when they type in the RadAutoComplete the last character they type isn't registering. I'll attach screen shots from two machines with the same search term and different results. Has anybody else reported this behavior? I'm just loading the search list in code behind it is really straight forward.

<telerik:radautocompletebox runat="server" Style="width: 200px;" id="acbInsured" MaxResultCount="20" DataTextField="CompanyName"     DataValueField="ClientKey">
</telerik:radautocompletebox>

 public void SetInsuredSearchDatasource(IEnumerable<Contact> searchResults)
        {
            acbInsured.DataSource = searchResults.ToArray();
            acbInsured.DataBind();
        }

 

public override void OnLoad()
        {
            SetInsuredSearchDatasource(_reportService.GetInsuredNameSearchResults());

...

 

I'm at a bit of a loss as to why it happens on some but not others (Same browser).

How to get the ContextMenu Items inside an ItemTemplate to fill the full available horizontal space

Hello,

i use a split button, which has a RadContextMenu attached to it. Inside the RadContextMenu, there is one RadMenuItem which contains an ItemTemplate with multiple RadCheckBoxes.

How is it possible that the RadCheckBoxes inside the ContentTemplate uses the full available width? So there should be no padding/margin in the ContextMenu and the Checkbox stretches horizontally to use all of the existing space. I uploaded an example of how it looks like right now in the attachments of this post.

 

 

Code:

<telerik:RadButton EnableSplitButton="true" ID="btn4" AutoPostBack="true"runat="server" Text="Example Button Text" OnClientClicked="OnClickedRadButton" CommandName="cmdBt4"   OnClick="btn4_Click" CausesValidation="true">
</telerik:RadButton>
<telerik:RadContextMenu id="rcmBtn4" runat="server">
   <Items>
      <telerik:RadMenuItem>
         <ItemTemplate>
            <p>
               <telerik:RadCheckBox runat="server" ID="rcb1" CausesValidation="false" Checked="true" Text="als Excel-Datei (.xlsx) exportieren" AutoPostBack="false" />
            </p>
            <p>
               <telerik:RadCheckBox runat="server" ID="rcb2" CausesValidation="false" Checked="true" Text="Checkbox Text 2" AutoPostBack="false" />
            </p>
         </ItemTemplate>
      </telerik:RadMenuItem>
   </Items>
</telerik:RadContextMenu>

RadChart multiple-series x-axis labels
I have a requirement to put multiple series into a chart. Each series should have a label & the item in the series should also have a label on the x-axis.
 I cannot find any samples that would help me with this and have been banging my head at it for the day.

 I've attached a sample of what our graph should look like. Any help on this would be great!


Thanks
