[Solved] Multiple RadCombobox in RadGrid

[Mehdi Baatout]

Hi all,
I work on a financial project and I am developping actually a window for accounting entry.
I am using a grid with EditMode="InPlace".
I have a problem in the column named BalanceAccountNumber :

<telerik:GridTemplateColumn HeaderText="Bal. Acc. Type" UniqueName="BalanceAccount" HeaderStyle-Width="150" >
                        <ItemTemplate>
                            <%# Guid.Parse(Eval("BalanceAccountTypeId").ToString()) != null?
                              ERPHR.BusinessObjects.FinBalanceAccountTypeRepository.GetNameByLanguage(Guid.Parse(Eval("BalanceAccountTypeId").ToString()), PageLanguage):"" %>
                        </ItemTemplate>
                        <EditItemTemplate>
                            <telerik:RadComboBox runat="server" ID="ddlBalanceAccountType" DataSourceID="edsBalanceAccounts" Width="140" AutoPostBack="true"
                                DataValueField="Id" DataTextField='<%# PageLanguage == ERPHR.AppUtilities.Enums.LanguageEnum.Arabic? "NameArabic": "NameEnglish" %>'>
                            </telerik:RadComboBox>
                        </EditItemTemplate>
                    </telerik:GridTemplateColumn>
                    <telerik:GridTemplateColumn UniqueName="BalanceAccountNumber" HeaderText="Bal. Acc. No" SortExpression="AccountNumber" ItemStyle-Width="150px">
                        <FooterTemplate>Template footer</FooterTemplate>
                        <FooterStyle VerticalAlign="Middle" HorizontalAlign="Center" />
                        <ItemTemplate>
                            <%# Guid.Parse(Eval("BalanceAccountId").ToString()) != null?
                              ERPHR.BusinessObjects.FinAccountRepository.GetAccountById(Guid.Parse(Eval("BalanceAccountId").ToString())).AccountNumber:"" %>
                        </ItemTemplate>
                        <EditItemTemplate>
                            <telerik:RadComboBox runat="server" ID="rcbBalanceAccountNumber" EnableLoadOnDemand="True" DataTextField="AccountNumber" DataValueField="Id" AutoPostBack="true"
                                HighlightTemplatedItems="true" Height="140px" Width="140" DropDownWidth="420px" OnItemsRequested="rcbBalanceAccountNumber_ItemsRequested">
                                <HeaderTemplate>
                                    <ul>
                                        <li class="col1">Account No</li>
                                        <li class="col2">Account Name</li>
                                    </ul>
                                </HeaderTemplate>
                                <ItemTemplate>
                                    <ul>
                                        <li class="col1">
                                            <%# DataBinder.Eval(Container, "Text")%>
                                        </li>
                                        <li class="col2">
                                            <%# DataBinder.Eval(Container, "Attributes['AccountName']")%>
                                        </li>
                                    </ul>
                                </ItemTemplate>
                            </telerik:RadComboBox>
                        </EditItemTemplate>
                    </telerik:GridTemplateColumn>

This column in edition or insertion is a RadCombox that the result is depending from the previous column(Balance Account Type):Balance Account Type in edition or insertion is also a RadComboBox and I need to retrieve in each time the SelectedValue of Balance Account Type RadComboBox to find her Balance account list. For that I am using this code :

protected void rcbBalanceAccountNumber_ItemsRequested(object sender, RadComboBoxItemsRequestedEventArgs e)
        {
            RadComboBox comboBox = sender as RadComboBox;
            RadComboBox rcbBalance = (RadComboBox)AccountPostingGrid.MasterTableView.GetInsertItem().FindControl("ddlBalanceAccountType");
            List<FinAccount> ListAccounts = BusinessObjects.FinAccountRepository.GetAccountByAccountNo(e.Text, Guid.Parse(rcbBalance.SelectedItem.Value));

            // Clear the default Item that has been re-created from ViewState at this point.
            comboBox.Items.Clear();

            foreach (FinAccount Account in ListAccounts)
            {
                RadComboBoxItem item = new RadComboBoxItem();
                item.Text = Account.AccountNumber;
                item.Value = Account.Id.ToString();
                item.Attributes.Add("AccountName", PageLanguage == LanguageEnum.Arabic ? Account.NameArabic : Account.NameEnglish);

                comboBox.Items.Add(item);
                item.DataBind();
            }
        }

My Problem is that I always the rcbBalance.SelectedItem.Value is the same : the value of the first Item of Balance Account Type RadComboBox.
Any idea about this problem????

Hi Mehdi,

Please try the following code snippet to access the RadcomboBox in the Template column:

C#:

protected void rcbBalanceAccountNumber_ItemsRequested(object sender, RadComboBoxItemsRequestedEventArgs e)
{
  RadComboBox comboBox = sender as RadComboBox;
  GridEditableItem edit = (GridEditableItem)comboBox.NamingContainer;
  RadComboBox rcbBalance = (RadComboBox)edit.FindControl("ddlBalanceAccountType");
  string valu = rcbBalance.SelectedItem.Value; // Get the Selected value of the BalanceAccountType
  // Your code
}

Thanks,
Princy

Hi Mehdi,

I was not able to replicate the issue, the code works fine at my end. Here is a sample that i tried:

ASPX:

<telerik:RadGrid ID="RadGrid1" runat="server" AutoGenerateColumns="False" DataSourceID="SqlDataSource1"AutoGenerateEditColumn="true" AllowPaging="true">

    <MasterTableView CommandItemDisplay="Top" EditMode="InPlace">

        <Columns>

            <telerik:GridTemplateColumn HeaderText="CustomerID" UniqueName="CustomerID" DataField="CustomerID">

                <ItemTemplate>

                    <%# Eval("CustomerID")%>

                </ItemTemplate>

                <EditItemTemplate>

                    <telerik:RadComboBox runat="server" ID="IDCombo" DataSourceID="SqlDataSource1" DataValueField="OrderID"
AutoPostBack="true" DataTextField="CustomerID">

                    </telerik:RadComboBox>

                </EditItemTemplate>

            </telerik:GridTemplateColumn>

            <telerik:GridTemplateColumn UniqueName="ShipCountry" HeaderText="ShipCountry" SortExpression="ShipCountry">

                <ItemTemplate>

                    <%# Eval("ShipCountry")%>

                </ItemTemplate>

                <EditItemTemplate>

                    <telerik:RadComboBox runat="server" ID="CountryCombo" EnableLoadOnDemand="True" DataTextField="ShipCountry" DataValueField="OrderId" AutoPostBack="true" HighlightTemplatedItems="true" OnItemsRequested="CountryCombo_ItemsRequested">

                        <HeaderTemplate>

                            <ul>

                                <li class="col1">OrderId</li>

                                <li class="col2">ShipCountry</li>

                            </ul>

                        </HeaderTemplate>

                        <ItemTemplate>

                            <ul>

                                <li class="col1">

                                    <%# Eval("OrderID")%>

                                </li>

                                <li class="col2">

                                    <%# Eval("ShipCountry")%>

                                </li>

                            </ul>

                        </ItemTemplate>

                    </telerik:RadComboBox>

                </EditItemTemplate>

            </telerik:GridTemplateColumn>

        </Columns>

    </MasterTableView>

</telerik:RadGrid>

C#:

protected void CountryCombo_ItemsRequested(object sender, RadComboBoxItemsRequestedEventArgs e)
{
 RadComboBox comboBox = sender as RadComboBox;
 GridEditableItem edit = (GridEditableItem)comboBox.NamingContainer;
 RadComboBox ID = (RadComboBox)edit.FindControl("IDCombo");
 string IDvalue = ID.SelectedItem.Value; // value of previous combobox
 // Your code
}

Thanks,

I have resolved the problem : My problem is that I have another column in the grid with required field, in all my tests I try to choose the balance type before filling this column.
The required field  block the postback to the server!!!
