Telerik Grid Sorting Functionality not stable for Description Column(MultiLine Text)

In my page I have used telerik grid with sorting functionality. In that I have a many columns with different datatype(Single, multiline, date, etc..)
I have a bulk of data, which I have updated day to day. In that grid, the sorting functionality is working fine for all types of columns but the column (Description) which has multiline text does not sort stable.
Example: Some data starts with number(1, 2 , ..) and Character(A, B, C, ..) and Special Character with/without number/character(1\2 , 1#, 1 D, etc..)
The sorting functionality is working fine for contents starts with both number and Character.(i.e 0, 1, 2, ...,9, A, B, C,... Z)
But the contents starts with Special Character with/without number/character is does not sort stable.
Example: 0, 1, 10, A, B....Z, 1/2, 1#, 2 D, A, B, ..Z(i.e its having two manner of sorting.. 0 to Z and again 1/2 to Z)

Pls can Anyone Help me

Thanks

RadGrid DeleteCommand

Hello my dear RadGrid friends!

In my project I implemented a RadGrid with a custom data access, nothing like all the examples provided (direct sql, etc.). Here's my NeedDataSource method:

    
                    /// <summary> 
        
                    /// Defining the PartnerListGrid's data, i.e. providing a datascource 
        
                    /// </summary> 
        
                    /// <param name="source"></param> 
        
                    /// <param name="e"></param> 
        
                    protected void PartnerListGrid_NeedDataSource(object source, Telerik.Web.UI.GridNeedDataSourceEventArgs e) 
        
                    { 
        
                        PartnerAgent partneragent = new PartnerAgent(); 
        
                        Partner[] partners = partneragent.Load(); 
        
                        if (!displayMessages(partneragent)) 
        
                        { 
        
                            var partnerselects = from p in partners 
        
                                                 select new 
        
                                                 { 
        
                                                     ID = p.PartnerID, 
        
                                                     Name = p.Name, 
        
                                                     Type = p.Partnertype.Name, 
        
                                                     Contacts = String.Join("<br />", p.Contacts.Select<Contact, String>(cn => String.Concat(cn.Prename, " ", cn.Name)).ToArray()), 
        
                                                     Mainaddress = p.Mainaddress, 
        
                                                     Links = new HyperLink[] { new HyperLink() { Text = "Projekte" }, new HyperLink() { Text = "Passwörter" }, new HyperLink() { Text = "Keys" }, new HyperLink() { Text = "PCs" }, new HyperLink() { Text = "Server" }, new HyperLink() { Text = "Domains" } } 
        
                                                 }; 
        
                            PartnerListGrid.DataSource = partnerselects; 
        
                        } 
        
                    }

Now I want to get the provided row by in the DeleteCommand, but all I could find was a text-attribute from a cell containing something half-way similar like the DataItem.
Unfortunately, the DeleteCommand's DataItem is empty.
Looks like following:

    
                    protected void PartnerListGrid_DeleteCommand(object source, GridCommandEventArgs e) 
        
                    { 
        
                        GridDataItem x = ((RadGrid)source).Items[e.Item.ItemIndex]; 
        
                        var HereIsSomeDataAvailable = x.Cells[2].Text; 
        
                        // HOW??? 
        
                        /*var activerow = InformationAgent.CastByExample(x.Cells[2].Text, new { ID = Guid.Empty, Name = "", Type = "", Contacts = "", Mainaddress = "", Links = new HyperLink[] { new HyperLink() { Text = "test" }, new HyperLink() { Text = "test2" } } });
        
                        PartnerAgent partneragent = new PartnerAgent();
        
                        partneragent.deletePartner(activerow.ID);
        
                        displayMessages(partneragent);*/ 
        
                    }

The part on the bottom, commented out, is my previous try, however, unfortunately the data from the cell is not convertable to the previously generated anonymous type.

Please tell me if you need any further data to provide help.
And also don't hesitate to tell me if I've chosen a wrong/chaotic way to work with the RadGrid ^^

Thanks in advance for your help!
Best
Roman

Public Property on pageview

I need to pass some information across the tabs and save all that information to the database on the submit button.
I have some datatable and some other values that I need to pass on each tab.

I was trying to create a public property and access the properties on the last tab but those peoperties don't show up against the usercontrol.
Is it possible to access public properties? Is there any other way I can use the same datatable across all tabs?

RadMultiPage multiPage = (RadMultiPage)this.NamingContainer.FindControl("rmChange");

RadPageView pvStatus = multiPage.FindPageViewByID("Status");

Control ucStatus = pvMaritalStatus.FindControl("StatusUserControl");

CancelImageUrl does not work in hierarchy

Hello,
We use a grid with 2 levels with inline edit, and the same CancelImageUrl works fine on the first level, but not on the second level, where the default cancel image is always shown (see screenshot attached)

<radG:GridEditCommandColumn ButtonType="ImageButton" UniqueName="ChildEditCommandColumn" HeaderStyle-Width="3%" CancelImageUrl="~/App_Themes/Cerib/Images/Buttons/FlecheGauche.gif" />

Thanks

Also when the user click on that image button I would like to refresh the content of the user control to display the exact number of received messages.

<asp:ImageButton ID="BtnNotif" width="153" height="42" runat="server" />

<telerik:RadToolTip ID="RttNotifs" runat="server"

TargetControlID="BtnNotif" RelativeTo="Element"

ManualClose="true" ShowEvent="OnClick"

Position="BottomCenter" RenderInPageRoot="False"

Skin="Hotlinexxx" EnableEmbeddedSkins="false"

Width="300px" Height="200px" >

<uc1:notifications runat="server" ID="notifications" />

</telerik:RadToolTip

I don't know exactly how to do it and do not find any relevant example on the demo website, could you please let me know how you would take care of it ?

Thanks for your support,

Custom Filter keeping previous search

Hi,

Im using a custom filter and want to use my own filter function (wanted to use wildcard options like * and ?), I followed the indications of this link: http://www.telerik.com/help/aspnet-ajax/grid-custom-option-for-filtering.html and the custom filter works.

Nevertheless the grid keeps the previous filter values I used before, I mean, if I used the value "test*" for the name column it gets all the rows that the name starts with "test" but if I change the filter value and hit enter, the MasterTableView.FilterExpression value keeps the value of the filter I used before

Here is my code

aspx

<asp:SqlDataSource ID="ds" SelectCommand="SELECT * FROM table" runat="server"></asp:SqlDataSource>

<telerik:RadGrid ID="grd" runat="server" DataSourceID="ds" AutoGenerateDeleteColumn="false" AllowAutomaticDeletes="true" AllowFilteringByColumn="True" OnInit="RadGrid_Init" AllowMultiRowSelection="true" OnItemCreated="RadGrid_ItemCreated" OnItemCommand="RadGrid_ItemCommand">

<ClientSettings>

<Selecting AllowRowSelect="True"></Selecting>

<ClientEvents OnRowSelected="Grid_RowSelected" OnRowDeselected="Grid_RowDeselected" />

</ClientSettings>

<MasterTableView ClientDataKeyNames="ID" AutoGenerateColumns="False">

<Columns>

<telerik:GridBoundColumn DataField="Name" HeaderText="Event Name" CurrentFilterFunction="Custom" AutoPostBackOnFilter="true" ShowFilterIcon="false"></telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="Year" HeaderText="Event Year" CurrentFilterFunction="EqualTo" AutoPostBackOnFilter="true" ShowFilterIcon="false"

></telerik:GridBoundColumn>

</Columns>

</MasterTableView>

</telerik:RadGrid>

c#

protected void RadGrid_ItemCommand(object source, GridCommandEventArgs e)

{

if (e.CommandName == RadGrid.FilterCommandName)

{

Pair filterPair = (Pair)e.CommandArgument;

if (filterPair.First.ToString() != "EqualTo")

{

string colName = filterPair.Second.ToString();

TextBox tbPattern = (e.Item as GridFilteringItem)[colName].Controls[0] as TextBox;

string value = tbPattern.Text;

if (value != string.Empty)

{

e.Canceled = true;

string newFilter = string.Empty;

if (value.IndexOf("*") >= 0) newFilter = "(([" + filterPair.Second + "] LIKE '" + value.Replace("*","%") + "'))";

else if (value.IndexOf("?") >= 0) newFilter = "(([" + filterPair.Second + "] LIKE '" + value.Replace("?", "%") + "'))";

else newFilter = "(([" + filterPair.Second + "] ='" + value + "'))";

if (grd.MasterTableView.FilterExpression == "")

{

grd.MasterTableView.FilterExpression = newFilter;

}

else

{

grd.MasterTableView.FilterExpression = "((" + grd.MasterTableView.FilterExpression + ") AND (" + newFilter + "))";

}

grd.Rebind();

}

For instance, this is the value the grid is using after a couple of filter changes, the first value was 2010* and the second was *annu*.

MasterTableView.FilterExpression = "(((([EventName] LIKE '2010%'))) AND ((([EventName] LIKE '%annu%'))))"

I if clear the filter textbox, hit enter and then enter the new filter value it does clear the MasterTableView.FilterExpression value

Thanks
