Hi All,

Can i have feature like "Virtual scrolling and paging" in RadListView similar to RadGrid?
I have large amount of data to bind with ListView and it is taking too long to bind.
Is there any option for lazy binding data when user scroll within listview?(server side)

Thanks,
Dipal

Hello Telerik Team

Hi,

We have recently updated telerik controls. Earlier We were using 2009 version. Now we updated to 2012 3.5 version. After Updating the telerik treeview controls and applying skins, there are lot of gap between two nodes. Earlier it was not like that. It was having proper gaps between two nodes. As we have around 500 nodes, Height of page is now increased and user has to scroll for getting desired node.

Can you provide us the proper skin\stylesheet which will minimize the gap between two nodes?

Thanks,
Ankit Trivedi

Community,

I have a RadGrid that I define my columns. Most of them are visible and read only; however, a few are updated. I also have a few columns that are not visible. I use these in my SQL update as my primary key. When you enter the RadGrid I automatically enable edit in every row of the entire grid for the editable columns. When a user is done doing a bulk update, they click my Update All button and the following code is ran:

protected void RadGrid1_ItemCommand(object source, Telerik.Web.UI.GridCommandEventArgs e)
    {
        if (e.CommandName == "EditAll")
        {
            foreach (GridItem item in RadGrid1.MasterTableView.Items)
            {
                if (item is GridEditableItem)
                {
                    GridEditableItem editableItem = item as GridDataItem;
                    editableItem.Edit = true;
                }
            }
        }
        if (e.CommandName == "UpdateAll")
        {
            //-- foreach (GridEditableItem editedItem in RadGrid1.EditItems)
            foreach (GridDataItem dataItem in RadGrid1.MasterTableView.Items)
            {
                Hashtable newValues = new Hashtable();
                e.Item.OwnerTableView.ExtractValuesFromItem(newValues, dataItem);
                SqlDataSource1.UpdateCommand = String.Format("UPDATE MY_TABLE SET AOScan_Num='{0}', PLANNED_REMEDIATION_STATUS_ID='{1}', " +
                    "ServiceNow_Num='{2}', TICKET_CREATION_DATE='{3}' WHERE QID='{4}' AND IP='{5}' AND PORT='{6}'",
                    newValues["AOScan_Num"], 
                    newValues["PLANNED_REMEDIATION_STATUS_ID"], 
                    newValues["ServiceNow_Num"], 
                    newValues["TICKET_CREATION_DATE"],
                    dataItem["QID"].Text, 
                    dataItem["IP"].Text, 
                    Convert.ToInt32(dataItem["PORT"].Text));
                SqlDataSource1.Update();
                dataItem.Edit = false;
            }
        }
        RadGrid1.Rebind(); 
    }

The problem I am running into is, when my code executes the SQL it returns the correct values from RadGrid for each row; however, the fields that are not visible and not editable are empty instead of holding the correct value. I was hoping someone has an idea of what might be going on.

Kind Regards,

Ben

Hi there,

At the moment I am using both the auto-generated edit form and the FormTemplate for my grid.
When I use the FormTemplate I want to have the update and cancel buttons the same skin for the buttons as the ones from the auto-generated edit form.

At the moment I use the code below inside the FormTemplate for the Cancel button.
Is there a way the button does not use the ImageUrl="~/Images/Cancel.gif" property but the skin set of my project?

Regards,

Marcel

 

<asp:ImageButton ID="ibCancel"

ImageUrl="~/Images/Cancel.gif"                                              

runat="server" Text="Cancel" CausesValidation="false" CommandName="Cancel" />

Hi there,

I am looking for a way to style the first column of my grid.
I want to have the backcolor of all the cells of the first column the same as the backcolor of the grid header depending of the skin used.

So if I use the skin 'Default' all the cells of the first column should have the backcolor of the grid header of the skin 'Default'.

Does anybody know how to do this?

Regards,

Marcel

Hi,

I got problem with asp:RequiredFieldValidator for RadEditor, but this only happen in IE (I'm using IE 9).
This is my code :


The validator doesn't work.
It seems like the ID "txtBody" is not attributed to the RadEditor. But I'm not sure.
Can you help me?

Hi,

For some reason, IE will not display my autocomplete with the DropDownHeight that I specify for my RadAutocompleteBox.
The DropDownWidth works just fine but the height does not at all.

I have set the Dropdownheight to "100" and I expect that when I type in something that results in a lot of suggestion items, The suggestions list will be 100px tall with a scrollbar in the control itself. But what is happening is that the suggestions list is just one tall list with no scrollbar and instead the scrollbar appears for the entire browser's client area

In the code behind, if I read the value of the  DropDownHeight property of the control it returns 100px which is what I expect, but for some reason the rendering is not honoring that value :(

I have checked that I have no css overriding any of the a RadAutoCompleteBox properties so I am not sure where to go next. 
FYI: here is the code snippet for my autocomplete box which is basically a straight copy from one of the demo pages on telerik.


Any pointers or suggestions on how to get to the bottom of this and fix it will be highly appreciated

Thanks

I am using paired ListBox objects.  When an item is transferred from one to the other, the item row where the transferred item is moved from remains highlighted.  Assume three items in the left ListBox and none in the right.  Click on the top item in the left list box and transfer it to the right.  The result is two items in the left ListBox and one in the right, as expected.  What is unexpected is that the top item in the left ListBox is now highlighted.  I have tried to address the issue in the OnClientTransferred handler with the following:

 sourceBox.clearSelection();
destinationBox.clearSelection();
for (i = 0; i < sourceBox.get_items().get_count(); i++)
{
        var item = sourceBox.getItem(i);
        item.unselect();
        item._unhighlight();
}

That did not resolve the issue.  The following is the tag used to declare the RadListBox:

<telerik:RadListBox ID="lstUnassignedSecurity" runat="server" Width="210px" Height="150px" AutoPostBack="false" 
SelectionMode="Multiple" AllowTransfer="true" TransferToID="lstAssignedSecurity" AutoPostBackOnTransfer="False"
EnableDragAndDrop="true" OnClientTransferred="listTransferring" ButtonSettings-ShowTransferAll="false">
    <Items>
    </Items>
</telerik:RadListBox>.
