Grid with LinQ with Selecting event

I have a grid that uses a LinqDataSource. The LinqDataSource uses the event Selecting to fill out the data retrieved. All works fine except that even though I am using a RadAjaxManager the grid still "blinks" when I use the paging controls instead of how the 300,000 row Telerik demo works. Will I not be able to accomplish that with the way I am doing it? My Linq query is a join. I have attached the code I use. If anyone has any tips, please let me know. I like the way the demo handles the postbacks.

[Solved] ClientSelectColumn: SelectAll(header) event

Hi All,

I am using 2009 q2 of Telerik.

I have a grid with client select column and I want to show an alert on uncheck of client select checkbox.

I captured the event deselecing for the checkbox and shown alert.

But the problem is when I do DeSelect All from header check box, I am getting alert for all the rows. I need an event for DeSelectAll so that I can set a flag and do not show alert for all rows, and show only one alert.

Which event I can use for DeSelect All?

Thanks.

Jimmy.

Sub Objects and Filtering

Hi Experts,

We have a Grid that we bind using the Simple Object collection.
The Format of the Object is such that:
ParentObject
            ChildObjectCollection
                        ChildObjectProperty

Hence when we bind our grid we provide the collection of ParentObject to it.
We have a GridBoundColumn there with following settings:
    .UniqueName = "MyColumn"

.DataField =

"ChildObject(0).sFullName" or "ChildObject.(0).sFullName"

.DataType =

GetType(String)

This work perfectly fine and we are able to see the data as required.
But the issue is that when we are trying to filter on this column its not responding at all and seems like its not able to find the column itself.Hence the grid is still intact with same number of rows.
We have also set the EnableLinqExpressions = false, hence filtering operation is more close to SQL version.
I also tried setting the FilterExpression manually before the NeedDataSource Event and check that expression is still there.But still same result.
Please let me know if you have ideas.
Thanks for your help in advance

Regards,
Aayam Singh

radgrid takes wrong class attributes

Hi

I'm having trouble getting the right data in my radgrid. I am working with an asp.net webapplication with C# and a WCF webservice. This webservice returns me a list of values which I have to put in class so I can show them in my radgrid. The problem is that the radgrid gets the wrong attributes. Can somebody take a look at this code and tell me what I'm doing wrong? Here's my code:

codebehind (c#):

                    foreach (string key in keys) {         
            if (lijst.TryGetValue(key, out value)) {         
                    properties.Add(new VO_ObjectPropertyHelper(key,value[0],value[1]));         
                  }         
            }         
                     
            rgProperties.DataSource = properties;         
            rgProperties.MasterTableView.DataSource = properties;         
                     

VO_ObjectHelper class:

                    public partial class VO_ObjectPropertyHelper {         
                    public string propID { get; set; }         
                    public string name { get; set; }         
                    public string value { get; set; }         
                     
                    public VO_ObjectPropertyHelper(string _propID, string _name, string _value) {         
                        this.propID = _propID;         
                        this.name = _name;         
                        this.value = _value;         
                    }         
                }         

webpage:

                    <telerik:RadGrid ID="rgProperties" runat="server" AutoGenerateColumns="False" GridLines="None" AllowSorting="True" ShowHeader="false" Skin="Vista">

RadGrid Ajaxed Postbacks the First Time

The following UserControl, OpportunityList.ascx, using the Ajaxed RadGrid refreshes the whole page the first time in when you click the Next button in the paging navigation bar. Subsequently, it works properly refereshing only the control itself. Is there a fix for this?

[By the way we bind the data to the radGrid in the UserControl's Page_PreRender event, otherwise we get the error
Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page. If there is a better way to work around this error, please let us know.]

I have checkboxes in rad combobox.
My first checkbox has the value All.
What I want is, I would like to select checkboxes for all when 'All' is selected,and if any one checkbox is deselected, then the check of 'All' should be deselected.

Below is the aspx code of rad combobox.
I want to achieve this through javascript.

<

radC:RadComboBox runat="server" ID="RadComboBox1" AllowCustomText="True" HighlightTemplatedItems="True"

Skin="WebBlue" SkinsPath="~/RadControls/ComboBox/Skins" UseEmbeddedScripts="False"

OnClientDropDownOpening="OnClientDropDownOpening" OnClientDropDownClosing="OnClientDropDownClosing"

OnClientSelectedIndexChanging="onSelectedIndexChanging" OnClientBlur="OnClientBlur"

DropDownWidth="140px" Height="110px" Width="120px">

<asp:CheckBox runat="server" ID="chk" onclick="checkboxClick();" Text='<%# DataBinder.Eval(Container, "Text") %>' />

</ItemTemplate>

<Items>

<radC:RadComboBoxItem Text="All" Value="0" ID="chbSelectAll" onclick="javascript:SelectAll();" runat="server" />

<radC:RadComboBoxItem Text="Unassigned" Value="1" runat="server" />

<radC:RadComboBoxItem Text="Assigned" Value="2" runat="server" />

<radC:RadComboBoxItem Text="Reassigned" Value="4" runat="server" />

<radC:RadComboBoxItem Text="Posted" Value="5" runat="server" />

</Items>

</radC:RadComboBox>

Persist state during postback

I use the PanelBar for navigation to other pages, which triggers a postback - thereby resetting the state of the PanelBar. I would like the PanelBar to persist the collapse/expand state of its items regardless of postbacks. I have tried the various fixes such as setting the PreventCollapse property on Items, trapping expand events client-side, etc but been unsuccessful in retaining state. It appears the only way to persist state is to write some sort of custom state handler that uses a hidden input field? Any advice would be appreciated.

Thanks!
Justin

btw: I am using the PanelBar in Sharepoint.

                    function companyDropDownClosed(sender, args) { 
        
                        var cboCompanybox = $telerik.toComboBox(sender); 
        
                        var selectIndex = cboCompanybox.get_selectedIndex(); 
        
                        cboUsers = $telerik.findComboBox('<%= Page.FindControlRecursive("cboUsers").ClientID %>'); 
        
                        if (selectIndex == -1) { 
        
                            cboUsers.clearSelection();

                        userCbo.trackChanges(); 
        
                        if (userCbo.get_items().get_count() == 0) { 
        
                            chkNewUser.trigger('click'); 
        
                            userCbo.disable(); 
        
                            userCbo.commitChanges(); 
        
                            return; 
        
                        } 
        
                        else { 
        
                            userCbo.enable(); 
        
                            var comboItem = new Telerik.Web.UI.RadComboBoxItem(); 
        
                            comboItem.set_text(""); 
        
                            comboItem.set_value(""); 
        
                            var items = userCbo.get_items() 
        
                            items.insert(0, comboItem); 
        
                            userCbo.commitChanges(); 
        
                            if (chkNewUser.attr("checked")) 
        
                                chkNewUser.trigger('click'); 
        
                        } 
        
                    var cnHidVal = $telerik.$('#' + '<%= Page.FindControlRecursive("selectedUser").ClientID %>'); 
        
                    if (cnHidVal.val() != "") { 
        
                        for (i = 0; i < userCbo.get_items().get_count(); i++) { 
        
                            var item = userCbo.get_items().getItem(i); 
        
                            if (item.get_value() == cnHidVal.val()) { 
        
                                item.select(); 
        
                            } 
        
                        } 
        
                    }

Then on the server side i have an Custom Validator which does the following

    
            protected void cboUsers_Validate(object sender, ServerValidateEventArgs args) 
        
                    {  
        
                        var newUserchecked = (System.Web.UI.WebControls.CheckBox)Page.FindControlRecursive("chkNewUser"); 
        
                        RadComboBox cboUsers = (RadComboBox)Page.FindControlRecursive("cboUsers"); 
        
                        args.IsValid = (newUserchecked.Checked) || (cboUsers.SelectedValue != "-1" && !newUserchecked.Checked); 
        
                    }

HTML Code here

    
            <telerik:RadComboBox runat="server" OnClientLoad="cboUser_Load" OnClientItemsRequested="cboUserItemsRequest" OnClientSelectedIndexChanged="cboUser_IndexChanged" 
        
                                                                    OnItemsRequested="cboUsers_ItemsRequested" Width="100%" ID="cboUsers" /> 
        
                                                                <asp:CustomValidator OnServerValidate="cboUsers_Validate" ErrorMessage="Please Select a User" ControlToValidate="cboUsers" 
        
                                                                    EnableClientScript="false" Display="None" runat="server" />

BUT on the server side code SelectedValue is "" i have got a work around which is to put the selected value into a hidden input field but i shouldn't have too.
