Filtering with other date format don't work

[Hans van Rijnswoud]

Hi,

We use in the Grid different column with the date format : dd-MM-yyyy (01-02-2009).
The standard filtering don't work.
I read different post and the documentation ( with many broken links) about this problem but i don't found any solution.

Do you have a nice sample to implement the filter with different format date who's work.
I use for the date only the filter Equal To.

Bellow my code:

     <telerik:RadGrid ID="RadGrid1" runat="server" Skin="Office2007"
                        GridLines="None" PageSize="13" Height="455px" OnNeedDataSource="RadGrid1_OnNeedDataSource"
                        AutoGenerateColumns="false" OnInit="RadGrid_Init" AllowSorting="true" AllowPaging="true" EnableViewState="false"
                        PagerStyle-AlwaysVisible="true" AllowFilteringByColumn="true" FilterItemStyle-HorizontalAlign="Left">
                        <MasterTableView DataKeyNames="ReactionId" Width="100%" IsFilterItemExpanded="true" AllowFilteringByColumn="true">
                            <Columns>
                                <telerik:GridBoundColumn DataField="ReactionId" HeaderText="Id" AllowFiltering="false" UniqueName="ReactionId" SortExpression="ReactionId">
                                    <HeaderStyle HorizontalAlign="Left" Width="20" />
                                    <ItemStyle HorizontalAlign="Left" Width="20" Wrap="false" Height="20px" />
                                </telerik:GridBoundColumn>
                                <telerik:GridTemplateColumn UniqueName="VacancyName" DataField="VacancyName" InitializeTemplatesFirst="false" SortExpression="VacancyName" AllowFiltering="true">
                                    <HeaderTemplate>
                                        <asp:LinkButton ID="btnVacancyName" Text="Vacaturetitel" ToolTip="Sorteren per vacaturetitel" CommandName="Sort" CommandArgument="VacancyName" runat="server"></asp:LinkButton>
                                    </HeaderTemplate>
                                    <HeaderStyle HorizontalAlign="Left" />
                                    <ItemTemplate>
                                         <telerik:RadCodeBlock ID="RadCodeBlock1" runat="server">
                                            <asp:LinkButton ID="btn_EditReaction" runat="server" CommandArgument='<%#Eval("ReactionId")%>' CssClass="lnk" CommandName="EditReaction" OnClick="Edit_OnClick" CausesValidation="false"><%#Eval("VacancyName")%></asp:LinkButton>
                                         </telerik:RadCodeBlock>
                                    </ItemTemplate>
                                    <ItemStyle Width="100%" HorizontalAlign="left" />
                                </telerik:GridTemplateColumn>
                                <telerik:GridBoundColumn DataField="StatusName" HeaderText="Status" UniqueName="StatusName" SortExpression="StatusName">
                                    <ItemStyle HorizontalAlign="Left" Wrap="false" />
                                </telerik:GridBoundColumn>
                                <telerik:GridBoundColumn DataField="ReactionDate" HeaderText="Reactiedatum" UniqueName="ReactionDate" DataType="System.DateTime" DataFormatString="{0:dd-MM-yyyy}" SortExpression="ReactionDate">
                                    <ItemStyle HorizontalAlign="Left" Wrap="false" />
                                </telerik:GridBoundColumn>
                            </Columns>
                        </MasterTableView>
                        <PagerStyle Mode="NextPrevAndNumeric" NextPageText="Volgende pagina" PrevPageText="Vorige pagina" NextPagesToolTip="Volgende pagina" PrevPagesToolTip="Vorige pagina" PagerTextFormat="Pagina: {4}  Pagina {0} tot {3} op {5}"  />
                        <GroupingSettings CaseSensitive="false" />
                        <FilterMenu EnableTheming="true" Skin="Office2007">
                            <collapseAnimation Duration="200" Type="OutQuint" />
                        </FilterMenu>
                        <ClientSettings AllowDragToGroup="False" EnableRowHoverStyle="true"></ClientSettings>
                    </telerik:RadGrid>

and the filter code :

/// <summary>
        /// reduce menu filter options
        /// </summary>
        /// <param name="sender">object</param>
        /// <param name="e">EventArgs</param>
        /// translation:
        /// NoFilter = Geen filter
        /// Contains = Bevat het woord
        /// Equal to = Gelijk aan
        /// StartsWith = Begint met
        /// EndsWith = Eindigd met
        protected void RadGrid_Init(object sender, EventArgs e)
        {
            GridFilterMenu menu = RadGrid1.FilterMenu;
            int i = 0;
            while (i < menu.Items.Count)
            {
                if (menu.Items[i].Text == "NoFilter")
                {
                    menu.Items[i].Text = "Geen filter";
                    i++;
                }
                else if (menu.Items[i].Text == "Contains")
                {
                    menu.Items[i].Text = "Bevat het woord";
                    i++;

                }
                else if (menu.Items[i].Text == "EqualTo")
                {
                    menu.Items[i].Text = "Gelijk aan";
                    i++;
                }
                else if (menu.Items[i].Text == "StartsWith")
                {
                    menu.Items[i].Text = "Begint met";
                    i++;
                }
                else if (menu.Items[i].Text == "EndsWith")
                {
                    menu.Items[i].Text = "Eindigd met";
                    i++;
                }
                else
                {
                    menu.Items.RemoveAt(i);
                }
            }
        }

Thanks for your help.

Hi Edwin Blom,

When you apply the following DateTime format - dd/MM/yyyy the filter criteria will be retained on paging/sorting operation. Note, however, the OrderDate column with be filtered "separately" from the rest of the grid columns, meaning that:

• the filters for the other columns in the grid will be cleared when you choose filter pattern for the OrderDate column
• the OrderDate column filter will be cleared when you specify filter for some other column

For more details review the following help topic:
Filtering for DateTime bound column with DataFormatString different than mm/dd/yyyy

I hope this information helps.
