How to set FilterExpression manually using dates

I want to do something like

RadGrid1.MasterTableView.FilterExpression = "SubmitDate >= '01/10/2008' and SubmitDate <= '02/01/2008'";
RadGrid1.Rebind();

But I get an error (something about a character literal can't be greater than 1 character). SubmitDate is a DatTime field in the db.

Maybe this can't be done, not sure.

Any Ideas on how I can accomplish this?

Thanks

hierarchy grid refresh issue

I have a hierarchy grid that is populated on demand (server side) using the NeedDataSource and DetailTableDataBind events (single level detail table) based on your example provided in the documentation.

Everything works fine but I have noticed that if 2 child levels are opened/expanded at the same time the second one does not refresh correctly. When I click to expand to see the details in another row I have correct number of pages but no data in the grid.

If I only have one sub level expanded/opened at the time everything works fine – for example I close/hide the details before I open/expand another row.

What else do I need to do to fix the refresh issue.

RadFormDecorator is not really free? It prompt me to buy it.

Today i am happy to found telerik's FormDecorator to style my standard asp.net web control, and it's free, there is no reason i don't give it a try.

I open a new blank new ASP.NET 4.0 project to test, but after a 10+ times postback.
telerik control's response.write a prompt message about : ( To remove this message, please purchase a developer version )

I have Attached a screenshot below.

Below is the markup of my test project.
And i have few question,

1. Is it the RadScriptManager1 and RadSkinManager1 not include in free FormDecorator suite?
2. I have remove the RadScriptManager1 ,but it show error :
"The control with ID 'RadFormDecorator1' requires a ScriptManager on the page. The ScriptManager must appear before any controls that need it."
So, do i have to use the classic ScriptManager come from ASP.NET 4.0?

3. Where can i add my free license information for register? web.config? of place a app_license.dll in /bin folder like "De*Express" and "Comp*nentArt" ?

[Solved] can't hide expand and collapse images in radgrid

Hi

I am using the radgrid 5.1.2.0 and I can't hide the plus and minus images in the group header. I have been following the example in this help file

ms-help://telerik.radgrid.51.Net2/telerik.radgrid.51.Net2/grdPreventGroupsExpansion.html

but it's not working

I've set the client settings on the grid like so:

<

rad:RadGrid id="dgStock" runat="server" Width="400px" Skin="Windows"

<

ClientSettings Resizing-AllowColumnResize="true" />

then i have this in the code behind

Protected Sub RadGrid1_ColumnCreated(ByVal sender As Object, ByVal e As Telerik.WebControls.GridColumnCreatedEventArgs) Handles dgStock.ColumnCreated

If TypeOf e.Column Is GridGroupSplitterColumn Then

e.Column.HeaderStyle.Width = Unit.Pixel(1)

e.Column.ItemStyle.Width = Unit.Pixel(1)

e.Column.Resizable =

False

End If

End Sub

but the expand collapse buttons are still there.

I also tried adding this code

Private Sub RadGrid1_PreRender(ByVal sender As Object, ByVal e As System.EventArgs) Handles dgStock.PreRender

For Each column As GridColumn In dgStock.MasterTableView.RenderColumns

If (TypeOf column Is GridGroupSplitterColumn) Then

column.HeaderStyle.Width = Unit.Pixel(1)

column.ItemStyle.Width = Unit.Pixel(1)

column.Resizable =

False

End If

The grouping of the grid is achieved as shown below

<

GroupByExpressions>

<

rad:GridGroupByExpression><SelectFields>

<

rad:GridGroupByField FieldName="StockType" FieldAlias="StockType" FormatString="" HeaderText=""></rad:GridGroupByField>

</

SelectFields>

<

GroupByFields>

<

rad:GridGroupByField FieldName="StockType" FieldAlias="StockType" FormatString="" HeaderText=""></rad:GridGroupByField>

</

GroupByFields>

</

rad:GridGroupByExpression>

</

GroupByExpressions>

Many thanks for your help

ComboBox Filter doesn't work

Hi there,

I am sure it is something very trivial, but I've spent couple of hours on that already and I think I am missing some obvious thing at that point.

I am trying to have something similar to next demo: http://demos.telerik.com/aspnet-ajax/combobox/examples/functionality/filteringcombo/defaultcs.aspx

However, filtering just doesn't work at all. Typing in the ComboBox is not doing anything.

Here is my sample application:

<telerik:RadScriptManager ID="m1" runat="server"/>

<telerik:RadComboBox ID="b1" runat="server" AutoPostBack="true"

AllowCustomText="true" Filter="Contains"

Style="vertical-align: middle;" Width="100px" Label="Filter:">

<Items>

<telerik:RadComboBoxItem Text="None" Value="0" />

<telerik:RadComboBoxItem Text="Contains" Value="1"/>

<telerik:RadComboBoxItem Text="StartsWith" Value="2" />

</Items>

</telerik:RadComboBox>

As you can see example is very simple and there is literally nothing in there.

I also tried setting

DataTextField to Text or Value. Doesn't matter - still no results.

I also tried to do DataBind() from server side code to ObservableCollection<string> and Dictionary<string,string> with no results as well.



Please advise.



Thanks,

Nick

Left align export buttons

Hello,

I am setting up a grid similar to the one found at :

http://demos.telerik.com/aspnet-ajax/grid/examples/generalfeatures/exporting/defaultvb.aspx

Except, I would like to have the export button on the left side instead of far right.

Is that possible?

Thank you,

Sadiq N.

Getting radgrid first, to be inserted dataitem on client

HI,

I need to traverse through radgrid dataitems on client to perform some logic. It looks like my code works fine in readonly and update mode, however it does not work when
I am trying to insert any item in the grid. Basically I do not know how to get reference to the "to be inserted item".

For example, if I am inserting first item in the grid then
masterTableView.get_dataItems().length returns 0.
So the Question is:
1. how do I reference the "To be inserted item"
2. how do I get a reference an element/control inside "To be inserted item")
Please Help...

Here is my javascript function:

function getTaxableOrderSubTotal()

{

var taxableOrderSubTotalAmnt = 0.00;

var radGrid = $find('<%= RadGrid1.ClientID %>');

var masterTableView;

var tableViewRows;

var length = 0;

if (radGrid) {

masterTableView = radGrid.get_masterTableView();

}

if (masterTableView) {

tableViewRows = masterTableView.get_dataItems();
