Cant access the radComboBox objects on a form

Hi, im using C# and linq

I have to store the values of the selected items from my RadComboBoxes into a database.

I have a form with 15+ comboBoxes which get populated from the database on_load, i also have a "Save" button that should be saving selectedValues of those boxes into another database. When i enter the "Click" event for my "Save" button i do not have access to any of the comboBox objects.
And when i say i do not have access to the object,i have a Box with the ID="cboAccount", i cannot call cboAccount.SelectedValue for example.

So i tried the following just to check if i could get access to the selected values

RadComboBox oops = new RadComboBox();

oops.ID = "cboAccount";

Response.Write("<script language='javascript'>alert('" + Server.HtmlEncode(oops.SelectedValue) + "')</script>");

but once the message displays the message is blank.

I already know how to insert data into a database with linq i just need to know how can i access the actual ComboBox Objects and the selected values so i can insert the data into the database.

thanx

RadComboBox within RadWindow

Hello and Thank you for your help in advance,

I am facing an issue where I have two rad windows, and each rad window contains a radcombobox.
These rad windows are opened on the client and are basically just two small forms.
There are submit buttons in each rad window which provide a post back and a stored procedure call.
The problem I am seeing is that it takes a page refresh from browser two these the results in either radcombobox - even though I have autopostback (they are set as default) set to true on both submit buttons. Each stored procedure affects the other combo box data.
The rad windows are on the same page - and not on different pages. I would like to keep it this way - is there any way that this result could be achieved?

The Control DataSource or (DataSourceID) is not set

Hello,

I've the following code to bind:

var lstEmployees = employeeRepository.All.Select(employee => new { employee.Id, employee.Name });

txtEmployee.DataSource = lstEmployees.ToList();

txtEmployee.DataTextField = "Name";

txtEmployee.DataValueField = "Id";

txtEmployee.DataBind();

This code is called in the Page_Load() event inside the

if (!IsPostBack) block.

This triggers the error "The Control DataSource or (DataSourceID) is not set" when I start typing into it.
What I noticed is, when I move the binding code outside the if (!IsPostBack) block, it works correctly.

[Solved] Export to Excel number format

I have the following problem.

When a number in the grid is formatted in the format used in France (10 123 in stead of 10.123) and when i export to excel, excel does not see this as a number, because of the space.

Is there a way that it will always be exported as 10123, so without any formatting?

RadGrid customValidation client side JS get edit item values

Hi

I'm trying to implement a clientside custom validation for my rad grid, and while I have managed to write the javascript function that gets called when the custom validator is fired, I am not sure how to access the edit form controls inside the function.

Here's a stripped down version of my markup.
Basically the grid has a "location" column and a "Storage Location" column and I use a FormTemplate based edit form for the insert/edit.
When inserting a record, I need to validate that only one of these two is selected.

<telerik:RadGrid

SkinID="myTemplate"

ID="myGrid"

runat="server"

DataSourceID="myDataSourceID"

OnInsertCommand="OnInserting"

OnUpdateCommand="OnUpdating">

<MasterTableView

DataKeyNames="myDataKey">

<CommandItemSettings

AddNewRecordText="Assign Location" />

<EditFormSettings

CaptionFormatString="Edit Location"

InsertCaption="Add New Location"

EditFormType="Template">

<FormTemplate>

<table id="Table10">

<tr>

<td>

<des:LocalizableLabel

ID="Location"

runat="server"

Text="Location"></des:LocalizableLabel>

</td>

<td>

<aec:TelerikAutoCompleteBox

ID="locationsAutoComplete"

runat="server"

DataSourceID="sqlLocationAutocomplete"

DataTextField="Name"

DataValueField="Location_ID"

Filter="Contains"

TextSettings-SelectionMode="Single"

InputType="Text">

</aec:TelerikAutoCompleteBox>

</td>

</tr>

<tr>

<td>

<des:LocalizableLabel

ID="StorageLocation"

runat="server"

Text="Storage Location"></des:LocalizableLabel>

</td>

<td>

<aec:TelerikDropDown

runat="server"

DataField="Storage_Location"

DataTextField="Storage_Location"

DataValueField="Storage_Location"

DataSourceID="sqlStorageLocation"

ID="storageLocationDropDown">

</aec:TelerikDropDown>

<asp:CustomValidator

runat="server"

ID="customValidator1"

ClientValidationFunction="EquipmentLocation_ClientValidate"

OnServerValidate="validateLocation"

ControlToValidate="storageLocationDropDown"

ErrorMessage="Must select either Location or Storage Location."

Display="static">

</asp:CustomValidator>

</td>

</tr>

</table>

<AERadGrid:EditFormSaveCancelButtons

ID="locationAssignEditFormButtons"

runat="Server">

</AERadGrid:EditFormSaveCancelButtons>

</FormTemplate>

</EditFormSettings>

<Columns>

<telerik:GridBoundColumn

UniqueName="Location_Name"

HeaderText="Location"

DataField="Location_Name">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn

UniqueName="Storage_Location"

HeaderText="Storage Location"

DataField="Storage_Location">

</telerik:GridBoundColumn>

</Columns>

</MasterTableView>

</telerik:RadGrid>

Here's the JS

function EquipmentLocation_ClientValidate(source, args) {

//get a reference to the calling validator control

var CustomValidator1 = source.id;

/* get the values of the location auto complete and the storage location ddl and compare.*/

var storageLocation = args.Value;

var location = ?? //GET the value out of the autocomplete box....how?

}

Now the JS function does get called as expected, in which I want to check the selected values in the autocomplete and the dropdown and allow only one to be selected. The value of the drop down is directly available in the args, but I'm not sure how I can get the value out of the autocompletebox on the edit form.

How do we get it?

Thanks
