Best way to programatically alter filters

Hi there,

I need to do some changing (not just creating an initial filter) of filters from 'outside' the radgrid (like adding a filter based on another dropdown). For example adding a filter to an already filtered grid from some event that occurs. I've seen things on using the filterExpression property, but I think that might get hairy if a filter is already applied and I want to manipulate it via string editing that property. Is there a better, more API-centric way to add/remove filters from external influences rather than hacking the filterExpression string?

Any pointers would be appreciated.

Thanks!

John

[Solved] Get column width after databind

I have columns that are sized to fit the data, I am not setting the widths. With this format, is there a way to find the widths of the columns once all of the data has been bound to the grid?

I'm trying to truncate text and append an ellipsis (...), but the user can choose to hide or show columns, so I can't hard code the columns widths. I need to find a way to find the widths, and calculate the number of characters to allow from that.

rgResults.Columns[i].HeaderStyle.Width.Value

is returning 0.0

Clicking checkbox on node quickly doesn't always work properly

Using version 2013.1.417.35 and Internet Explorer 10.

If you attempt to check/uncheck the checkbox of a node in a RadTreeView quickly, the node does not always successfully check or uncheck. (No postbacks occur.) Is there a reason for this, or is it a small bug?

Thanks,
Kyle

[Solved] ItemCreated event trigger

I need to know if there is a way to determine what is triggering my ItemCreated event when I have a GridEditableItem in edit mode and the user is clicking the "Update" button, "cancel Button" or neither. On my page, the itemCreated event is being triggered when the user clicks the update or cancel button when my GridEditableItem is in editmode. This is fine. However, the event is also triggered if another control on my page is clicked while my GridEditableItem is in edit mode and it's click event forces a page load. If this happens, I could run into a situation where my grid row is open for update/cancel, a new page is loaded and my grid row remains open for update/cancel after the page has been refreshed (which I do not want). I want to force "cancel" the edit mode when this happens, before the page is refreshed. Since I'm able to capture the logical flow of activity in the ItemCreatedEvent when the user does something on my page that is outside of the update/cancel activity of my row, I need to be able to determine what type of activity is firing off the ItemCreated event (update/cancel or neither) in order to assess whether to manually kick off the cancel event through the item's FireCommand method or not. Is there a way to do this?

RadComboBox loadondemand resets position when data is fetched.

Hi.

As stated in the title, the position keeps resetting to the 1st element in the combobox as soon as new data is added to the combobox. Below is the itemrequested code I use.

Protected Sub cboInstrument_ItemsRequested(ByVal sender As Object, ByVal e As RadComboBoxItemsRequestedEventArgs)

Try

Dim oSender As Telerik.Web.UI.RadComboBox = DirectCast(sender, Telerik.Web.UI.RadComboBox)

oSender.DataValueField = "Name"

oSender.DataTextField = "Name"

Dim data As List(Of Instrument)

If Not String.IsNullOrWhiteSpace(ExchangeComboBox.SelectedValue) Then

data = GetData(ExchangeComboBox.SelectedValue, e.Text, False)

Dim itemOffset As Integer = e.NumberOfItems

Dim endOffset As Integer = Math.Min(itemOffset + ItemsPerRequest, data.Count)

'e.EndOfItems = endOffset = IIf(data.Count = 1, 0, data.Count)

e.EndOfItems = endOffset = data.Count

For i As Integer = itemOffset To endOffset - 1

oSender.Items.Add(New RadComboBoxItem(String.Format("{0} - {1}", data(i).Symbol, data(i).Name), data(i).ExchangeSymbolKey))

Next

e.Message = GetStatusMessage(endOffset, data.Count)

Else

Dim endOffset As Integer = 0

oSender.Items.Add(New RadComboBoxItem("Select an Exchange", Nothing))

e.Message = GetStatusMessage(endOffset, 0)

End If

Catch exc As Exception

ProcessModuleLoadException(Me, exc)

End Try

End Sub

Any help will be greatly appreciated.

Regards

[Solved] get_masterTableView not working

I've had a tough time trying to figure out how to access my grid on client side. I've tried everything I could find, and nothing seems to work. I FINALLY got my grid object ($find didn't work for me), but now get_masterTableView() isn't doing anything. If I step through the javascript, it steps into the line and just disappears into some WebResource.axd abyss and never returns. I don't get any javascript errors.

If I try to run the function in the console, it says "undefined is not a function".

Here's my code

<script type="text/javascript">

function GridCreated(grid) {

var mtv = grid.get_masterTableView();

var pageIndex = mtv.get_currentPageIndex();

alert(pageIndex);

}

</script>

<radG:RadGrid ID="rgResults" runat="server" AllowMultiRowSelection="True" AllowPaging="True"

AllowSorting="True" EnableAJAX="False" GridLines="None" OnItemCommand="rgResults_ItemCommand" OnItemDataBound="rgResults_ItemDataBound"

PageSize="20"

Skin="Default" Width="100%" OnPageIndexChanged="rgResults_PageIndexChanged" OnSortCommand="rgResults_SortCommand" OnInit="rgResults_Init" OnPreRender="rgResults_PreRender">

<ClientSettings ApplyStylesOnClient="True">

<ClientEvents OnGridCreated="GridCreated(this);" />

</ClientSettings>

<ItemStyle CssClass="griditemtext" />

<FooterStyle CssClass="gridfootertext" />

</ExpandCollapseColumn>
