ExpressionItemCreated gets fired even for existing expressions

When I add an expression, the ExpressionItemCreated gets fired not only for the expression I'm adding, but for all existing expressions as well. Is this normal behavior?

RadGrid Filter

Hello everyone,

I would like to know how it's possible to choose which filters we need. In fact at the beginning, we have NoFilter, Contains, DoesNotContain (too much)... And I would like only Contais and EqualTo. So how it works?

Thank you.

how to send data into function using onclientselectedindexchanged

oComboBox.OnClientSelectedIndexChanged = "ShowHideTextbox('" & oComboBox.ClientID & "','" & oTextbox.ClientID & "','" & oLabel.ClientID & "')"

^ doesn't work and I see on API I should just have a function name there such as this?
oComboBox.OnClientSelectedIndexChanged = "ShowHideTextbox"

inside my js function I see I can do this
var item = eventArgs.get_item();

but how can I assign my 3 values into arguments called into the function?

Change cell font color on RadGrid Rebind()

Hi,

The text color of my cells is not updated when I call the Rebind() of my RadGrid.

I've implemented my logic as the following :

- I fill my grid datasource in the NeedDataSource event

- I set the style logic in the ItemDataBound event

Protected Sub RgPermisMontage_ItemDataBound(sender As Object, e As Telerik.Web.UI.GridItemEventArgs) Handles RgPermisMontage.ItemDataBound

If TypeOf e.Item Is GridHeaderItem Then

'''

ElseIf TypeOf e.Item Is GridGroupHeaderItem Then

'''

ElseIf TypeOf e.Item Is GridDataItem Then

Dim item As GridDataItem = e.Item

If item("ysnDepotPrev").Text Then

item("dtDepot").ForeColor = Color.FromArgb(218, 95, 37)

item("dtDepot").Font.Italic = True

Else

item("dtDepot").ForeColor = Color.Black

item("dtDepot").Font.Italic = False

End If

'''

End If

End Sub

Then I update my grid source so I call the Rebind() to force the RadGrid to raise NeedDataSource event and ItemDataBound.

My cell value is well updated but the cell style not.

Do you have any ideas ?

Disable RadGrid Databinding

Hi, I have a problem with my grid. This grid is showed to the user, in a popup, when he click on a link.

This is my grid:

<div id="dialog" >

<telerik:RadGrid ID="RadGrid1" RenderMode="Lightweight"

ClientDataSourceID="RadClientDataSource1"

AllowPaging="false" AllowSorting="false" AllowFilteringByColumn="false"

PageSize="5" runat="server" >

<MasterTableView DataKeyNames="Name" ClientDataKeyNames="Name" >

<Columns>

<telerik:GridBoundColumn DataField="Name" HeaderText="Name">

</telerik:GridBoundColumn>

</Columns>

</MasterTableView>

</ClientSettings>--%>

</telerik:RadGrid>

</div>

and this is my RadClientDataSource:

<telerik:RadClientDataSource ID="RadClientDataSource1" runat="server" >

<ClientEvents OnCustomParameter="ParameterMap" OnDataParse="Parse" />

<DataSource>

<WebServiceDataSourceSettings BaseUrl="../ReportService.svc/">

<Select Url="GetFlusso" DataType="JSON" RequestType="Post" ContentType="application/json; charset=utf-8"

EnableCaching="false" />

</WebServiceDataSourceSettings>

</DataSource>

<Schema ResponseType="JSON" >

<Model>

<telerik:ClientDataSourceModelField FieldName="Name" DataType="String" />

</Model>

</Schema>

</telerik:RadClientDataSource>

This is my link (created with javascript):

"<a href='javascript: openScartiDialog(" + id + ");'><em>CLICK</em></a>"

where id is a parameter for a select method on web service.

Now, these are the functions that parse to/from my web service:

function ParameterMap(sender, args) {

if (args.get_type() == "read" && args.get_data()) {

var dialog = $("#dialog");

var id = dialog.id;

if (id != undefined) {

var request = {

InputContract: {

IdFlusso: id

}

};

args.set_parameterFormat(kendo.stringify(request));

}

} else {}

}

function Parse(sender, args) {

var response = args.get_response().Output;

if (response) {

if (response.length > 0) {

args.set_parsedData(response);

} else {

var model = [];

}

All works. My Web Service works (I have tried with other grids).

The problem is: the request on the server (performed by the RadClientDataSource, called by the RadGrid) is made on page load.

I want to avoid this, I just want that the grid is loaded, showed on the link click (indeed, I want to pass the id parameter). But I don't know how.

To be more clear, this is the rest of my implementation: the js code for showing/hiding the popup and for set the id.

$(function () {

$("#dialog").dialog({ autoOpen: false, modal: true, show: "blind", hide: "blind", width: "auto",

buttons: {

"OK": function () {

$(this).dialog("close");

},

"Annulla": function () {

$(this).dialog("close");

}

});

function openScartiDialog(id) {

var div = $("#dialog");

div.attr('id', id);

div.dialog("open");

var grid = $telerik.findGrid("RadGrid1");

var m = grid.get_masterTableView();

m.rebind();

return false;

}
