Usercontrol not updated on click of button residing in another user control

I am facing problem of user control not updated.

Problem Narration:
As per my and client's requirement:
I've created two user control.
One user control having a drop down.
Another user control having few no of controls and its event.
Both user control i've used in my one web page twice.
FilterDropDown and FilterDropDownGridContact is two user control.(having only a drop down)

For partial postback I've used following AjaxSettings.

<telerik:RadAjaxManager ID="RadAjaxManager1" DefaultLoadingPanelID="RadAjaxLoadingPanel1"

runat="server">

<AjaxSettings>

<telerik:AjaxSetting AjaxControlID="btnSave">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="FilterDropDown" />

<telerik:AjaxUpdatedControl ControlID="FilterDropDownGridContact" />

</UpdatedControls>

</telerik:AjaxSetting>

</AjaxSettings>

</telerik:RadAjaxManager>

<telerik:RadAjaxLoadingPanel ID="RadAjaxLoadingPanel1" runat="server">

</telerik:RadAjaxLoadingPanel>

Below is code of user controls how i used in first place:

<UserControl:FilterDropDown ID="FilterDropDown" runat="server" GridID="gridLocation"

EnableViewState="true" pageName="UserProfile" PlaceHolderID="ContentPlaceHolder1" />

<UserControl:Filter ID="Filter" runat="server" GridID="gridLocation" EnableViewState="true"

PlaceHolderID="ContentPlaceHolder1" />

Below is code of user controls how i used in second time:

<UserControl:FilterDropDown ID="FilterDropDownGridContact" runat="server" GridID="gridClientContact"

EnableViewState="true" pageName="ClientContact" PlaceHolderID="ContentPlaceHolder1" />

<UserControl:Filter ID="FilterGridContact" runat="server" GridID="gridClientContact" EnableViewState="true"

PlaceHolderID="ContentPlaceHolder1" />

Below are the events attached in code behind:

protected void Page_Load(object sender, EventArgs e)

{

FilterDropDown.drpFilterChange += new EventHandler(drpFilter_SelectedIndexChange);

Filter.SaveFilter += new

EventHandler(SaveFilter); //attached with btnSave button

Filter.ClearFilterSelection += new EventHandler(ClearFilterSelection);

Filter.DeleteFilter += new

EventHandler(DeleteFilter);

FilterDropDownGridContact.drpFilterChange += new EventHandler(FilterDropDownGridContact_SelectedIndexChange);

FilterGridContact.SaveFilter += new

EventHandler(SaveContactFilter);//attached with btnSave button

FilterGridContact.ClearFilterSelection += new EventHandler(ClearContactFilterSelection);

FilterGridContact.DeleteFilter += new EventHandler(DeleteContactFilter);

//Other stuffs

}

When I debug my projects, all custom events fires and get updated data in code behind and in database too.
But it display old(Not updated) data on web page or drop down.

e.g.



Now when I click on btnSave of first user control event fires and as per ajax setting dropdown user control updates.



But, when I click on btnSave of second user control events fires but user control is not updated.

 

So, Whats issue??

 

Is there any way, so that i can update ajax setting such as update first
user control when respective user control's btnSave fires and so on.

Changing timeslot background color programmatically breaks hover background color

Hi,
I am setting background color of RadScheduler's time slot based on some data source attribute.

protected void Schedule_TimeSlotCreated(object sender, TimeSlotCreatedEventArgs e)
    {
              ................
   If(condition == 1)
                   e.TimeSlot.Control.BackColor = Color.White;
               else
      e.TimeSlot.Control.BackColor = Color.Grey;
                ....
}
On doing so, it is breaking hover background color (especially height). now, when I hover over a timeslot, it partially highlights it as seen in the image attached. How can I give a background color to time slot and also highlight 100% width and hieght of timeslot on hover?

Thanks,
Prava

set date on change

How do I set the date selected in txPayDate to txtPaydate1 on change? For example I have this:

<telerik:RadDatePicker ID="txtPayDate" Runat="server" OnDateSelected="OnDateSelected">

</telerik:RadDatePicker>

<telerik:RadDatePicker ID="txtPayDate1" Runat="server" >

</telerik:RadDatePicker>

I tried this in javascript:

function OnDateSelected(sender, e)

{

var dateInput = $find('<%= txtPayDate1.ClientID %>');

dateInput.set_value(args.get_newDate().format("MM/dd/yyyy"));

}

I tried this in code behind:

txtPayDate1.DateInput.SelectedDate = txtPayDate.DateInput.SelectedDate

a few hours on something that would take me 10 seconds in access.

RadGrid filter templates

Hello,

First, I wish you a happy new year ! :-)

Secondly, I am trying to include in the code of my RadGrid the filter template which is being shown here : http://demos.telerik.com/aspnet-ajax/grid/examples/programming/filtertemplate/defaultcs.aspx

But it seems that to fill the DropDown boxes , you are accessing the database each time by defining SqlDataSource objects (for example SqlDataSource1 in the code sample :

<asp:SqlDataSource ID="SqlDataSource1" ConnectionString="<%$ ConnectionStrings:NorthwindConnectionString %>"

ProviderName="System.Data.SqlClient" SelectCommand="SELECT CustomerID, ContactName, ContactTitle, City, Country, Bool FROM Customers"

runat="server"></asp:SqlDataSource>

What I want is to have in each dropdown box only the values that really appear into the corresponding RadGrid column (data from RadGrid datasource) and not all the available values from the database. For example, if I only have 3 different records in the grid, I just want to have the three corresponding values in my drop down boxes.

So can an you tell me how to define my DataSource for all DropDonwn boxes to achieve that ?I have been looking at ObjectDataSource but it seems that by using SqlDataSource or ObjectDataSource, il will always have to send an SQL request to the database. That's exactly what I want to avoid, as I already used an SQL request to retrieve the data when populating the RadGrid ...

Thank you for your help.

grd_itemdataboundcommand on grid with details table

Hi, I was wondering how I could go about the code behind on this. I have my grid which display records and can filter by active, inactive, etc... then when I want to look at further details, the details table does not populate and now I am getting an error on:

If

e.Item.ItemType = GridItemType.Item OrElse e.Item.ItemType = GridItemType.AlternatingItem Then

Dim record As table 1 = e.Item.DataItem<----------

that says:

Unable to cast object of type 'xxx.Model.database.table2' to type 'xxx.Model.database.table1' .

what is going on here?
