Grid does perform sort or paging in ajax mode

Hi everyone,

I am obviously not seeing something here. I have a simple grid instance with its the necessary ajaxsettings declared:

Ajax Setting for grid:

<telerik:RadAjaxManager runat="Server" ID="RadAjaxManager1">

<AjaxSettings>

<telerik:AjaxSetting AjaxControlID="UserView">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="UserView" LoadingPanelID="RadAjaxLoadingPanel1" />

</UpdatedControls>

</telerik:AjaxSetting>

</AjaxSettings>

</telerik:RadAjaxManager>

Grid instance: (allowsort and allowpaging both = true)

<telerik:RadGrid ID="UserView" GridLines="None" runat="server" AllowPaging="True"

AutoGenerateColumns="False" Skin="Windows7" AllowSorting="true" Width="722" OnNeedDataSource="UserViewNeedDataSource" PageSize="20">

<telerik:GridBoundColumn DataField="FullName" HeaderText="Name" SortExpression="FullName"

UniqueName="FullNameColumn" />

<telerik:GridBoundColumn DataField="UserName" HeaderText="User Name" SortExpression="UserName"

UniqueName="AdUserNameColumn" />

<telerik:GridBoundColumn DataField="Domain" HeaderText="Domain" SortExpression="Domain"

UniqueName="AdDomainColumn" />

</Columns>

</MasterTableView>

</telerik:RadGrid>

<telerik:RadGrid ID="UserView" GridLines="None" runat="server" AllowPaging="True"

AutoGenerateColumns="False" Skin="Windows7" AllowSorting="true" Width="722" OnNeedDataSource="UserViewNeedDataSource" PageSize="20">

<PagerStyle Mode="NextPrevAndNumeric"/>

<MasterTableView Width="722">

<Columns>

<telerik:GridBoundColumn DataField="FullName" HeaderText="Name" SortExpression="FullName"

UniqueName="FullNameColumn" />

<telerik:GridBoundColumn DataField="UserName" HeaderText="User Name" SortExpression="UserName"

UniqueName="AdUserNameColumn" />

<telerik:GridBoundColumn DataField="Domain" HeaderText="Domain" SortExpression="Domain"

UniqueName="AdDomainColumn" />

</Columns>

</MasterTableView>

</telerik:RadGrid>

Assignment of data:

protected void Page_Load(object sender, EventArgs e)

{

if(!IsPostBack)

{

GetUsers();

}

private void GetUsers()

{

UserView.DataSource = _client.GetUsers(null);

}

And from the documentation, it says the OnNeedDataSource event will fire after a page or sort event, so I have a handler:

protected void UserViewNeedDataSource(object sender, GridNeedDataSourceEventArgs e)

{

GetUsers();

}

protected void UserViewNeedDataSource(object sender, GridNeedDataSourceEventArgs e)

{

GetUsers();

}

The ajax call is happening, the event handler is being hit, but nothing happens. No sort, no paging.

Feedback would be appreciated. Version of control suite: v2010.2.929.40

Cheers,

Derek

Rebinding a grid in NestedViewTemplate

I have a RadGrid (RadGrid1) that has a nestedViewTemplate. In this NestedViewTemplate, another grid (RadGrid2) is loaded.
RadGrid2 has an imagebutton in each row that opens a RadWindow, where the user can make modifcations to the row in RadGrid2.
When the RadWindow is closed (OnClientClose="refreshGrid" ), this function is run

function refreshGrid() {

var args = null;

args = document.getElementById("inpHidden").value;

if (args) {

var mgr = $find("<%= RadAjaxManager1.ClientID %>");

if (mgr) {

mgr.ajaxRequest(args);

}

The RadAjaxManager1_AjaxRequest method rebinds the grid in the NestedViewTemplate without reloading the main grid RadGrid1. This is the desired behavior and works fine. However, if I click on the image button again, the function can no longer find a reference to RadAjaxManager1, which is on the control that holds the Main grid

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server" OnAjaxRequest="RadAjaxManager1_AjaxRequest">

<AjaxSettings>

<telerik:AjaxSetting AjaxControlID="RadAjaxManager1">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="RadGrid2" />

</UpdatedControls>

</telerik:AjaxSetting>

<telerik:AjaxSetting AjaxControlID="RadGrid2">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="RadGrid2" />

</UpdatedControls>

</telerik:AjaxSetting>

</AjaxSettings>

</telerik:RadAjaxManager>

<telerik:RadAjaxPanel ID="RadAjaxPanel4" runat="server" Width="100%" LoadingPanelID="RadAjaxLoadingPanel4">

<telerik:RadAjaxLoadingPanel ID="RadAjaxLoadingPanel4" runat="server"">

telerik:RadAjaxLoadingPanel>

<telerik:RadGrid ID="RadGrid1" ....

Any idea why the manager can no longer be found?

I have a page with a radgrid on it. The grid gets loaded with different datasets from code behind. Is there a way to set default filters for dynamically added columns? From what I read, this is not supported.

not

Hello,
Ive Created rad-combobox in code-behind (.cs file) and assign "RadComboBoxItem" collection through dataset.
Like -

public void PopulateDROPDOWN(RadComboBox drp,string dataval,string datatxt,string selected,string strSQL)

{

DataSet objdr;

RadComboBoxItem mylist;

try

{

objdr=GetDataSet(strSQL);

drp.Items.Clear();

mylist = new RadComboBoxItem();

mylist.Value = "0";

mylist.Text = "Select";

if (selected == null)

{

mylist.Selected = true;

}

drp.Items.Add(mylist);

foreach (DataRow myDatarow in objdr.Tables["cnpl"].Rows)

{

mylist = new RadComboBoxItem();

mylist.Value = myDatarow[dataval].ToString();

mylist.Text = myDatarow[datatxt].ToString();

if (selected ==myDatarow[dataval].ToString())

{

mylist.Selected = true;

}

drp.Items.Add(mylist);

}

catch

{

drp.Items.Clear();

mylist = new RadComboBoxItem();

mylist.Text = "Error";

mylist.Value = "Error";

drp.Items.Add(mylist);

}

But when I used foll. code to get selectedValue from combobox , it gives selectedText.

string val = FRM.Page.Request["radCombo_drp"];

In above code, val = selectedText.
I want to assign val = selectedValue

Please Help,
Thanks in advance...

<ContentTemplate>

<asp:UpdatePanel ID="UpdatePanel1" runat="server">

<ContentTemplate>

<%-- INCLUDE CONTENT - WEATHER --%>

<content:Weather ID="Weather1" runat="server"></content:Weather></ContentTemplate>

</asp:UpdatePanel>

</ContentTemplate>

</telerik:RadDock>

<asp:XmlDataSource ID="XmlWeather" runat="server"></asp:XmlDataSource>

<telerik:RadComboBox ID="CityList" Runat="server" AutoPostBack="true">

RadDatePicker database insert problem

Hi all,

protected void btnSignUp_Click(object sender, EventArgs e)

{

try

{

string guid = System.Guid.NewGuid().ToString();

System.Guid g = new Guid(guid);

string txtName = (fvwSignUp.Row.FindControl("txtName") as TextBox).Text;

string txtEmail = (fvwSignUp.Row.FindControl("txtEmail") as TextBox).Text;

string txtPassword = (fvwSignUp.Row.FindControl("txtPassword") as TextBox).Text;

string rcbGender = (fvwSignUp.Row.FindControl("rcbGender") as RadComboBox).SelectedValue;

// DateTime rdpDate = (fvwSignUp.Row.FindControl("rdpDate") as RadDatePicker).SelectedDate;

strConnection = ConfigurationManager.ConnectionStrings["pfms"].ConnectionString;

dbConn = new SqlConnection(strConnection);

dbConn.Open();

SqlCommand da = new SqlCommand("insert into SignUp values(@UserID,@UserName,@Email,@Password,@Gender,@BirthDate)", dbConn);

da.Parameters.Add("@UserID", SqlDbType.VarChar, 200).Value =guid;

da.Parameters.Add("@UserName", SqlDbType.VarChar).Value = txtName;

da.Parameters.Add("@Email", SqlDbType.VarChar).Value = txtEmail;

da.Parameters.Add("@Password", SqlDbType.VarChar).Value = txtPassword;

da.Parameters.Add("@Gender", SqlDbType.Int).Value = rcbGender;

SqlParameter p1 = da.Parameters.Add("@BirthDate", SqlDbType.DateTime);

p1.Value = rdpDate.Value;

// DateTime dMyDate = rdpDate.Value;

da.ExecuteNonQuery();

fvwSignUp.ChangeMode(FormViewMode.ReadOnly);

}

finally

{

if (dbConn != null)

{

dbConn.Close();

bindData();

}

I have an error msg show that:-
Error 5 The name 'rdpDate' does not exist in the current context

if i declare this radDatePicker, another error msg will display which is:-

Error 5 'System.DateTime' does not contain a definition for 'Value' and no extension method 'Value' accepting a first argument of type 'System.DateTime' could be found (are you missing a using directive or an assembly reference?)

Any help is appreciated....

Best regards,
Nasri

Ajaxified controls do not flow

I have 2 RadTextBox controls that I want to flow one after the other on a page if there is room. They work correctly until I ajaxify them, then they line up, the second one below the first (even though there is room on the page for them to be side by side.
The only difference I see in the HTML code as it runs is that the ajaxified controls are each wrapped with an additional <div >.

<telerik:RadTextBox ID="rtbIncidentStartTime" runat="server" ReadOnly="true" BackColor="#F8F8F8" Label="Incident Start Time" Width="310px">
