RadGrid_ItemCommand get a column's value when I know only the first 3 characters of the column name

Hello
I have a radgrid which is build from a cross table.
I need the get column's value, from the Radgrid_ItemCommand. The thing is that I don't know the whole name of the column. I only know the first 3 characters ("TRA") of the column.
Here is my code

    
            Private Sub RadGrid1_ItemCommand(ByVal source As Object, ByVal e As Telerik.Web.UI.GridCommandEventArgs) Handles RadGrid1.ItemCommand  
        
                    If e.CommandName = "UpdateAll" Then 
        
                        For Each editedItem As GridEditableItem In RadGrid1.EditItems  
        
                            Dim newValues As New Hashtable()  
        
                            e.Item.OwnerTableView.ExtractValuesFromItem(newValues, editedItem)  
        
                            SqlDsIntervenant.InsertCommand = String.Format("INSERT INTO T_COMPTENCES_TRANVERSALES (FICHE, MAT, GRP, NO_INTERV, COMPTENCES, NOM, PRENOM) VALUES (" & newValues("FICHE") & ",'" & newValues("MAT") & "', '" & newValues("GRP") & "', '" & newValues("NO_INTERV") & "', '" & newValues("COMPTENCES") & "','" & newValues("NOM") & "','" & newValues("PNOM") & "')")  
        
                            SqlDsIntervenant.Insert()  
        
                            editedItem.Edit = False 
        
                        Next 
        
                    End If 
        
                    RadGrid1.Rebind()  
        
                End Sub

Does somebody know how to get that?
Thank you!

radUpload present in a ajax panel bar

Hi i am using a radUpload control in a ajaxify panelbar. I came to know across seeing many forums since there is no post back the upload control always gives the count as "0". Later when i searched across i got a link which said how to used the upload control in the ajaxify panel bar. I tried the way but didn't get any changes. The link is
"http://www.telerik.com/help/aspnet-ajax/upload_uploadingajax.html"

in the topic "Alternative workaround for RadAjaxPanel (and RadGrid classic)"
I have a doubt in this code.. the CodeBehind says to create a click event..

protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostback)
{
   GetPostBackEventReference(this);
   ButtonSubmit.Attributes.Add( "onclick",
     string.Format("realPostBack('{0}', ''); return false;", ButtonSubmit.UniqueID));
}
}

The script code is

function realPostBack(eventTarget, eventArgument)
{
   __doPostBack(eventTarget, eventArgument);
}

Why do we send a single argument. i mean we just send the eventTarget and get eventArgument also which is always null. I am not clear in this.. if some one gets this to work please help me out in this as i am stuck in it.. and more over the solution given here is not working for me. :(

thanks in advance

[Solved] Additional rows not styled when changing page size

I use GridColumn Collection editor to set CSS classes because I need to style columns differently (just right/left alignment of text actually).

If default pagesize is 10 and I use the page control to select 20 or 50 then rows 11-20 / 11-50 are not styled.
If default pagesize is 20 and I select 50 then 21-50 are not styled.

If I do not set CSS classes in GridColumn Collection editor and instead set a css class in RadGrid properties then all additional rows are styled but then all columns are of course styled using same class.

Has anyone encountered this problem? What can be done to fix it?

Close /open in vb code ; to implement' add more to this page'

I have to close a rad doc,in a button press

What should I do for this?

We can close rad docs using close button on the right hand side of every raddock

But I want to close a rad dock in a button click

I am expecting some thing like

Sub Button1_click(………..)

RaddockLayout.findcontrol(“raddoc1”).close()

End sub

I also need a way to open a rad doc in another button click

It this two possible?

The reason why I asking this is because

I am trying to implement some thing like in the site

http://www.bbc.co.uk/ press “Add more to this page”

It shows only the web part for which we ticked.

One solution is to load docs dynamically (in vb codes) depending up on check boxex.

But I don’t like to load all dynamically.

NB:I am implementing personalization well working

Error when all context menus are not visible

Hi,
I have a page with a tree-view and two context menus that are not visible by default. When I select an item in the tree, I get a javascript error: 'Telerik.Web.UI.RadContextMenu is null or not an object'. I've fixed it for now by adding a "dummy" context-menu with no items in it (but with the Visible property set to 'true'), but I would like to know if there is a better solution.

Thanks.

Condiotional formatting with ItemTemplate

Hi,

I want to format an ItemTemplate conditionally but can't find a way to get archieve this.

I've read the Conditional Formatting for rows/cells on ItemDataBound topic but can't apply it to an ItemTemplate.

For example my aspx code:

    
                                <ItemTemplate> 
        
                                    <span style="display: block; float: left;"> 
        
                                        <%# Eval (Session["ntyp"].ToString())%> 
        
                                    </span>

                                    <span style="display: block; float: right;"> 
        
                                        <%# Eval("date")%> 
        
                                    </span> 
        
                                    <br /> 
        
                                    <span> 
        
                                        <%# Eval("subject")%> 
        
                                    </span> 
        
                                </ItemTemplate>

All what I want to do is, give the "subject" an individul style, depending on the value of "read" which is stored in the same table (not visible to users here) and could be empty or a string.

If I use a simple if statement checking the value using Eval("read") inside the ItemTemplate it trhows a TargetInvocationException.

Any help would be appreciated.

Regards

RagGrid, Encrypted Database Fields and Filtering

Hi, I was wondering if there is a solution for the following problem I'm having?

I have an asp.net function which encrypts data using AES 256bit. I'm then storing this encrypted data within varbinary fields in SQL Server.

The problem I'm having is filtering these values with RadGrid - the error reported is Sys.WebForms.PageRequestManagerServerErrorExcept is neither a DataColumn nor a DataRelation for table DefaultView.

For columns I'm using GridTemplateColumn type so I can decrypt and display the data correctly:

    
             <Columns> 
        
                 <telerik:GridTemplateColumn UniqueName="UserID" SortExpression="UserID" HeaderText="UserID" DataType="System.String">    
        
                    <ItemTemplate><%#cs_lib.Decrypt(Eval("UserID"), SqlDataSource1.SelectCommand, 3)%></ItemTemplate>    
        
                    <ItemStyle/>   
        
                    </telerik:GridTemplateColumn>  
        
                    <telerik:GridTemplateColumn UniqueName="FirstName" SortExpression="FirstName" HeaderText="FirstName" DataType="System.String">    
        
                    <ItemTemplate><%# cs_lib.Decrypt(Eval("FirstName"), sqlDataSource1.SelectCommand, 3) %></ItemTemplate>    
        
                    <ItemStyle/>   
        
                    </telerik:GridTemplateColumn>   
        
                      <telerik:GridTemplateColumn UniqueName="Surname" SortExpression="Surname" HeaderText="Surname" DataType="System.String">    
        
                    <ItemTemplate><%#cs_lib.Decrypt(Eval("Surname"), SqlDataSource1.SelectCommand, 3)%></ItemTemplate>    
        
                    <ItemStyle/>   
        
                    </telerik:GridTemplateColumn>   
        
                      <telerik:GridTemplateColumn UniqueName="EmailAddress" SortExpression="EmailAddress" HeaderText="EmailAddress" DataType="System.String">    
        
                    <ItemTemplate><%#cs_lib.Decrypt(Eval("EmailAddress"), SqlDataSource1.SelectCommand, 3)%></ItemTemplate>    
        
                    <ItemStyle/>   
        
                    </telerik:GridTemplateColumn>   
        
                    <telerik:GridDateTimeColumn DataField="DateCreated" DataType="System.DateTime"   
        
                        HeaderText="Created" SortExpression="DateCreated" UniqueName="DateCreated" ItemStyle-Width="175px" HeaderStyle-Width="175px"> 
        
                    </telerik:GridDateTimeColumn> 
        
                    <telerik:GridCheckBoxColumn DataField="SecurityAdmin" HeaderText="Security Admin"  
        
                        SortExpression="SecurityAdmin" UniqueName="SecurityAdmin"   
        
                        DataType="System.Boolean"> 
        
                    </telerik:GridCheckBoxColumn >         
        
                            <telerik:GridHyperLinkColumn AllowFiltering="False"  
        
                        DataNavigateUrlFields="UserID" Groupable="False" Text="Delete"  
        
                        UniqueName="DeleteColumn"> 
        
                    </telerik:GridHyperLinkColumn> 
        
                    <telerik:GridHyperLinkColumn AllowFiltering="False"  
        
                        DataNavigateUrlFields="UserID" Groupable="False" Text="Edit"  
        
                        UniqueName="EditColumn" DataNavigateUrlFormatString="edit.aspx?userid={0}"> 
        
                    </telerik:GridHyperLinkColumn> 
        
                    </Columns>

The filtering was working correctly before I started using varbinary fields types and AES encryption.

Is anyone aware of a possible solution for this?

Thanks
Mark

RadGrid Client Side binding and page size change

I have a radGrid and I am doing client-side binding. And I am using
PagerStyle Mode="NextPrevAndNumeric"

So when client changes the pageSize and I am trying to pass that information to my webservicerequest to get the new set of items as per that new pageSize as below

function RadGrid1_Command(sender, args) {
                //debugger;
                args.set_cancel(true);
                commandName = args.get_commandName();

                var searchText = $('.SearchText').val();
                var searchType = $('.SearchType').val();
                var searchId = $('.SearchID').val();
                var newPageSize = tableView.get_pageSize();
                tableView.set_pageSize(newPageSize);

                ISearchResultsService.getSearchResults(searchText, tableView.get_currentPageIndex(),
                            tableView.get_pageSize(), tableView.get_sortExpressions().toString(),
                            tableView.get_filterExpressions().toDynamicLinq(), searchType, searchId, updateGrid, onGetDataFailure2);
}

but I am manipulating columns in as below

function RadGrid1_RowDataBound(sender, args) {
                var imgbutton = args.get_item().findElement("img1"); // find control
                if (args.get_dataItem()["amazonThumbnailUrl"] != null && args.get_dataItem()["amazonThumbnailUrl"].toString() != "") {
                    imgbutton.src = args.get_dataItem()["amazonThumbnailUrl"].toString();
                }
                else {
                    imgbutton.src = "../Images/Listing/Thumbnails/" + args.get_dataItem()["ImageName"].toString();
                }
            }

But the HTML has only the initial pageSize and when it tries to rowDataBind the oldPageSize +1 it crashes since it cant find a value for Imgbutton in the above code, So what is work around for this situation to be able to change the pageSize in client side binding. I have also opened a support ticket, but thought posting here too for any workarounds?

Thanks
