Customize telerik grid HeaderContextFilterMenu

Hi,

I am using telrik grid having 'EnableHeaderContextFilterMenu' enabled. I want to customize header context filter menu in order to add custom combo box instead of text box in filter menu option. I am using 'GridTemplateColumn' having rad combo box in 'FilterTemplate' as mentioned below:-

<telerik:GridTemplateColumn DataField="UserType" InitializeTemplatesFirst="false"
                                    HeaderText="User Type" HeaderStyle-Width="100px" UniqueName="UserType" SortExpression="UserType"
                                    AllowFiltering="true" AutoPostBackOnFilter="true" FilterControlWidth="80px">
                                    <HeaderTemplate>
                                        <table>
                                            <tr>
                                                <td>
                                                    <asp:LinkButton ID="lnkSort2" runat="server" CommandArgument="UserType" CommandName="Sort"
                                                        Text="User Type"></asp:LinkButton>
                                                </td>
                                                <td>
                                                    <img src="App_Themes/Default/img/fillter_icon.png" style="vertical-align: middle;
                                                        margin-left: 5px; cursor: pointer" onclick='ShowColumnHeaderMenu(event,"UserType")'
                                                        alt="Show context menu" />
                                                </td>
                                            </tr>
                                        </table>
                                    </HeaderTemplate>
                                    <ItemTemplate>
                                        <asp:Label ID="lblUserType" runat="server" Text='<%# Eval("UserType")%>'></asp:Label>
                                    </ItemTemplate>
                                    <FilterTemplate>
                                        <telerik:RadComboBox runat="server" ID="radCmbUserType" DataValueField="UserType"
                                            AutoPostBack="true" DataTextField="UserType" Width="90px">
                                        </telerik:RadComboBox>
                                    </FilterTemplate>
                                </telerik:GridTemplateColumn>

Below is the function which binds rad combo box with the values:-

private void LoadFilterCombo()
        {
            if (null != grdAccounts && grdAccounts.MasterTableView.GetItems(GridItemType.Item).Count() > 0)
            {
                RadComboBox cboUserType = ((RadComboBox)((GridFilteringItem)grdAccounts.MasterTableView.GetItems(GridItemType.FilteringItem)[0])["UserType"].FindControl("radCmbUserType"));

                foreach (int index in Enum.GetValues(typeof(CampaignService.UserType)))
                {
                    RadComboBoxItem item = new RadComboBoxItem();
                    item.Value = index.ToString();
                    item.Text = Enum.GetName(typeof(CampaignService.UserType), index);
                    cboUserType.Items.Add(item);
                }

            }
        }

I want this rad combo box to be displayed in 'HeaderContextFilter Menus' instead of default textbox as shown in attached image in order to apply filter as per selected values in combo box.

can you please suggest any solution on this?

Thanks and Regards,
Deepti

RadAjaxManager and Dynamically loaded controls

Hello.
I have a MasterPage setup in a Web Application.
Based on different button clicks i load dynamically different usercontrols in a contentplaceholder.

ContentPlaceHolder cph = this.FindControl("ContentPlaceHolder1") as ContentPlaceHolder;

UserControl uc = this.LoadControl("~/UserControls/" + strName + ".ascx") as UserControl;

if ((cph != null) && (uc != null))

{

uc.ID = strName;

cph.Controls.Clear();

cph.Controls.Add(uc);

IsControlAdded = true;

ViewState[IDS_USERCONTROL] = strName;

}

The problem is that i need in Site.Master to use some js code that exists in a dynamically loaded usercontrol.
That seems to be no problem for the first loaded usercontrol because the usercontrols html is included in the master page html.
The problem arrises when i dynimically load the second usercontrol i find out that the html and js from the first usercontrol loaded persists in the master page and the second usercontrol's js and html is not loaded.

If i add EnableAJAX="false" to the radajaxmanager it solves my problem .. but then again .. that beats the purpose of using ajaxmanager.

switch (index) {

case 0: //Person

var arr = GetSelectedPerson();

args.set_cancel(true);

break;

case 1: //Company

break;

case 2: //Group

var arr = GetSelectedGroups();

break;

This is a code snipplet from Site.Master
GetSelectedPerson and GetSelectedGroups are two js methods that exist in different usercontrols.

Calling FireCommandEvent to remove filtering on multiple columns

Hi,

I have country and city column in the radgrid and I have defined a template filters using radcombobox for both the columns. I am able to filter on both columns.

The only problem I have is when removing filtering.

Say I have filtered on both Country and city column and then I select All in the Country Filter column.

In the country combo selectedindexchanged event I am clearing the filtering using the following command

                    filterItem.FireCommandEvent("Filter", new Pair("NoFilter", "Country"));         

The problem is that the filtering on the city column is still active. So i modified the above code to this

                    filterItem.FireCommandEvent("Filter", new Pair("NoFilter", "Country"));         
            filterItem.FireCommandEvent("Filter", new Pair("NoFilter", "City"));         

THe above code does not work. The FireCommandEvent works only for the first line, not for the second. I tried switching the statement order. Is it possible to remove filtering on multiple columns by calling FireCommandEvent multiple times.

Thanks

Image not vertically aligning middle for a Hyperlink grid column

I'm using an image with a hyperlink grid column but I am unable to get the image to vertically align in the middle. It almost appears like the grid is placing the image in the column an an unbreakable space ( & nbsp ;) causing the image to be forced to the top.

Any thoughts?

ReadOnly Field causes no Updates on RadGrid

Hello Everyone,

I have two questions about Radgrid that I never understood completely. I'm using the new telerik 2011.3.1305.40. ASP.NET AJAX.
I Send a download Link with a simple example to illustrate my doubts. http://www.omnilab.com.br/documentos/ReadOnlyFields.rar
In the example I have one table with 4 fields. One of them is the primary key and identity field.

When I run the example, all happens fine, I can Edit and Update the table, however:

When I make the field "id_movie" readonly, the table no longer updates. Why this happens? How can I solve this?
If I change the type of field "control" to bit (to enable checkbox), the table no longer updates. Why this happens? How can I solve this?

I appreciate anyone to clarify those doubts to me.

Regards,
Marcio Nascimento

Rad Editor dialogs and local filesystem

I'm trying to build something like a "newsletter manager" that allows the user to compose an html formatted message and then send it to mailing lists.
In a real scenario, the user would insert Images and/or other "contents" (something that's not just typed text) selecting it from its local hard drive.
Onche the content file has been selected, and the user has choosen some of its properties (i.e. height/width for an image) I would like to process this file, maybe resize/compact it, then upload to a specific website folder, and then have the url to that file inserted in the editor content.

I hoped that this was what the RadEditor ImageDialog and similar do, but it doesn't seems so.
I'm I wrong ar I'm I missing something ?

What is the preferred tecnique to achieve that goal ?

thx
Ubaldo

RadNumericTextBox broken now when validating Currency values

Something changed re: RadNumericTextBoxes in the newest version of the Telerik Rad Ajax Controls (2012.2.607.40)

Our client-side/markup validators are all now broken on any currency validation as the "$" and the "," values are being passed thru instead of the raw value.

This change just happened with this new version of the Ajax controls and we have a lot of code that is now broken in production.

Need someone at Telerik to address this ASAP.

<telerik:RadNumericTextBox ID="rntbBudget" runat="server" CssClass="TextboxAnimated" Width="150px"

Type="Currency" DataType="Decimal" DbValue='<%# Eval("fldBudget") %>' NumberFormat-DecimalDigits="2" />

<asp:RequiredFieldValidator ID="rfvBudget" runat="server" ControlToValidate="rntbBudget"

ErrorMessage="Must enter a Budget amount!" Text="!" CssClass="errorMessage" />

<asp:CompareValidator ID="cvBudget" runat="server" ControlToValidate="rntbBudget" ValueToCompare="0.00"

Operator="GreaterThan" Type="Currency" ErrorMessage="The Budget amount must be greater than $0.00!" Text="!" CssClass="errorMessage" />

The above code now generates a validation error when it never did before.

Jerry

**EDIT**

Below is a workaround, for now:

<telerik:RadNumericTextBox ID="rntbBudget" runat="server" CssClass="TextboxAnimated" Width="150px"

Type="Number" DataType="Decimal" DbValue='<%# Eval("fldBudget") %>' NumberFormat-DecimalDigits="2" NumberFormat-GroupSeparator="" />

<asp:RequiredFieldValidator ID="rfvBudget" runat="server" ControlToValidate="rntbBudget"

ErrorMessage="Must enter a Budget amount!" Text="!" CssClass="errorMessage" />

<asp:CompareValidator ID="cvBudget" runat="server" ControlToValidate="rntbBudget" ValueToCompare="0.00"

Operator="GreaterThan" Type="Currency" ErrorMessage="The Budget amount must be greater than $0.00!" Text="!" CssClass="errorMessage" />

Notice the changes: The Type attribute on the RadNumericTextBox had to be changed from "Currency" to "Number" and the NumberFormat-GroupSeparator attributte had to be added but set to an empty string "".

This means a LOT of our production code now needs to be modified due to this underlying change in the RadNumericTextBox control.

Why did that change? There was no mention of it in the release notes either.
