FilterTemplate filter value remains "All"

[Lenny_shp]

http://www.telerik.com/help/aspnet-ajax/radgrid-filter-template.html
The first time run it's correctly displaying "All", after I select a different dropdown item, the grid filters correctly, but the FilterDropDown still indicates "All".    How do I make it display the value that was selected?

Update:  It works now after I change it to use the client side version of example:

                    OnClientSelectedIndexChanged="TitleIndexChanged" SelectedValue='<%# TryCast(Container,GridItem).OwnerTableView.GetColumn("Application").CurrentFilterValue %>'


The Server side still has the issue:

<FilterTemplate>

<telerik:RadComboBox runat="server" ID="FilterCombo" DataSourceID="srcApplication" AppendDataBoundItems="true"

DataValueField="Application" DataTextField="Application" AutoPostBack="true"                         SelectedValue='<%# TryCast(Container,GridItem).OwnerTableView.GetColumn("Application").CurrentFilterValue %>'

OnSelectedIndexChanged="FilterCombo_SelectedIndexChanged">

<Items>

<telerik:RadComboBoxItem Text="All" />

</Items>

</telerik:RadComboBox>

</FilterTemplate>

</telerik:GridBoundColumn>

    Protected Sub FilterCombo_SelectedIndexChanged(ByVal o As Object, ByVal e As RadComboBoxSelectedIndexChangedEventArgs)
        Dim filterExpression As String
        filterExpression = "([Application] = '" + e.Value + "')"
        RadGrid1.MasterTableView.FilterExpression = filterExpression
        RadGrid1.MasterTableView.Rebind()
    End Sub

Hello Leonid,

To achieve the desired functionality I suggest that you use the approach in the following live demo.
Try to follow this scenario and let me know how it goes and if any other questions arise.

It does work with the javascript embedded client side, but only if filtering is on by default.
 I also tried to move the s"elect change"  function server side and the event never fired.

By default - I show my grids w/o the Filters, then a user can check a box to show them.

Client side when the filters are shown is says my "onchange" function is not found.
Server side - it never fires an autopostback.

If I dynamically turn on filtering - I get   Microsoft JScript runtime error: 'StatusIndexChanged' is undefined

 

OnClientSelectedIndexChanged="StatusIndexChanged"

 

 

Why doesn't 

 

OnSelectedIndexChanged="StatusIndexChanged"  call the server function - or how can I set the drop down list to be set for autopostback ?

 

In my codebehind - I Tried to set the autopostback:

 

Dim StatusDDL As RadComboBox = CType(filteringItem("Status").Controls(0), RadComboBox)

 

StatusDDL.Width = Unit.Pixel(100)

StatusDDL.AutoPostBack =

True

 

StatusDDL.DropDownWidth = Unit.Pixel(100)

But i get an error - Unable to cast object of type 'System.Web.UI.LiteralControl' to type 'Telerik.Web.UI.RadComboBox'.

Hi Rob,

Unfortunately we can not determine the exact cause for the issue you encountered without a working application which demonstrate it. At this point I will ask you to open a formal support ticket and send us a simple working project with reproduced this erroneous behavior. We will examine it in detail and will get back to you with our findings.

Best wishes,

Was there a solution for this bug? I have the same issue, but would like to use the code behind since I need this for multiple GridDropDownColumns. The filter works, but the index resets to the first entry. I've tested the code by manually setting e.value to "" while debugging.

.ascx Code:
            <telerik:GridDropDownColumn DataField="PRIORITY_ID" HeaderText="Job Priority"
                SortExpression="PRIORITY_ID" UniqueName="PRIORITY_ID"
                DataSourceID="sqlDSPriority" ListTextField="PRIORITY_NAME" ListValueField="PRIORITY_ID">
                <FilterTemplate>
                    <telerik:RadComboBox runat="server" ID="FilterPriorityID" AutoPostBack="true"
                        DataSourceID="sqlDSPriority" DataTextField="PRIORITY_NAME" DataValueField="PRIORITY_ID"
                        OnSelectedIndexChanged="FilterCombo_SelectedIndexChanged" AppendDataBoundItems="true">
                        <Items>
                            <telerik:RadComboBoxItem />
                        </Items>
                    </telerik:RadComboBox>
                </FilterTemplate>
            </telerik:GridDropDownColumn>

.ascx.cs Code:
        // Event handler for filtering the GridDropDownColumn
        // Note - The DataValueField has to equal the unique name of the GridDropDownColumn in order for
        //        this event handler to work.
        protected void FilterCombo_SelectedIndexChanged(object o, RadComboBoxSelectedIndexChangedEventArgs e)
        {
            // Check if we are clearing the filter expression
            if (string.IsNullOrEmpty(e.Value))
            {
                // Clear the filter expression
                RadGrid1.MasterTableView.FilterExpression = string.Empty;
            }
            else
            {
                // Set the filter expression
                RadGrid1.MasterTableView.FilterExpression = "([" + (o as RadComboBox).DataValueField + "] = '" + e.Value + "')";
            }

            // Rebind the data
            RadGrid1.MasterTableView.Rebind();
        }

Hello Gunjan,

To achieve the desired functionality, I suggest that you save the selected item OnSelectedIndexChange and retrieve the data OnPreRender event.
Give a try on the following code snippet and let me know how it goes.

ASPX:

 <telerik:GridDropDownColumn DataField="ContinentName" HeaderText="Continent" UniqueName="ContinentName"
                        ListValueField="ContinentName" ListTextField="ContinentName" DataSourceID="SqlDataSource1">
                        <FilterTemplate>
                            <telerik:RadComboBox ID="rcbContinents"
                                AppendDataBoundItems="true"
                                runat="server"
                                AutoPostBack="true"
                                DataSourceID="SqlDataSource1"
                                DataTextField="ContinentName"
                                DataValueField="ContinentName"
                                Skin="Vista"
                                OnSelectedIndexChanged="rcbContinents_SelectedIndexChanged"
                                OnPreRender="rcbContinents_PreRender">
                                <Items>
                                    <telerik:RadComboBoxItem Text="All" Value="" />
                                </Items>
                            </telerik:RadComboBox>
                        </FilterTemplate>
                    </telerik:GridDropDownColumn>

C#

protected void rcbContinents_SelectedIndexChanged(object o, Telerik.Web.UI.RadComboBoxSelectedIndexChangedEventArgs e)
    {
        RadComboBox continentsCombo = o as RadComboBox;

        //save the combo selected value
        ViewState["continentsComboValue"] = continentsCombo.SelectedValue;

        //filter the grid
        RadGrid1.MasterTableView.FilterExpression = "ContinentName LIKE '%" + continentsCombo.SelectedValue + "%'";
        RadGrid1.Rebind();
    }

    protected void rcbContinents_PreRender(object sender, EventArgs e)
    {
        //persist the combo selected value
        if (ViewState["continentsComboValue"] != null)
        {
            RadComboBox continentsCombo = sender as RadComboBox;
            continentsCombo.SelectedValue = ViewState["continentsComboValue"].ToString();
        }
    }

I hope this helps.

Thank you for the solution. I've added the PreRender function and it's now saving the selected index. My filter value is an integer, so the filter expression in your code will not work for me:

Original:
        RadGrid1.MasterTableView.FilterExpression = "ContinentName LIKE '%" + continentsCombo.SelectedValue + "%'";

New:
        RadGrid1.MasterTableView.FilterExpression = "ContinentName = " + continentsCombo.SelectedValue;

I had to modify my code to allow for multiple column filters, which is working, but only when a drop down filter is selected last. I enabled the auto-filtering for the grid view, which allows multiple columns to be filtered at once. When filtering on a non-drop down filter column, the filter expression seems to be removing the drop down list filter from the expression. Is this a bug or am I doing something wrong in my code?

Hi Gunjan,

If you want to customize filtering using your own custom statements, clear the FilterExpression string (to prevent the default filtering) and bind the grid to a filtered data set.

For more information, please refer to the following articles:
Basic filtering
Custom option for filtering (FilterListOptions -> VaryByDataTypeAllowCustom)
Operating with the FilterExpression of Telerik RadGrid manually

Thanks for the help. I was looking into other methods of filtering, and found that setting the filter expression of the column to work with my custom drop-down filter lists. The problem is rebinding the filtered data in the radgrid.

Steps:
1) Select an item from the drop-down filter list
2) Radgrid refreshes and data does not look filtered
3) On another column (GridDataBoundColumn) enter a filter expression
4) Radgrid refreshes filtering the data w/ both expressions.

Debugging my the PreRender handler (previous code to load drop down value from viewstate) the filter expression of the masterview contains the correct filter expression of the drop-down filter list. Shouldn't the Rebind() method work, or is there another method I need to call in order to filter the data?

Thanks,

Gunjan

C# code:

        protected void FilterCombo_SelectedIndexChanged(object o, RadComboBoxSelectedIndexChangedEventArgs e)
        {
            RadComboBox rcbFilter = o as RadComboBox;
            string rcbFilterExpr = "([" + rcbFilter.DataValueField + "] = " + rcbFilter.SelectedValue + ")";

            // Save the selected value
            ViewState[rcbFilter.ID] = rcbFilter.SelectedValue;

            // Add the filter expression
            foreach (GridColumn gc in this.RadGrid1.MasterTableView.Columns)
            {
                if (gc.UniqueName.Equals(rcbFilter.DataValueField))
                {
                    // Check if we are clearing the filter
                    if (string.IsNullOrEmpty(rcbFilter.SelectedValue))
                    {
                        gc.CurrentFilterFunction = GridKnownFunction.NoFilter;
                        gc.CurrentFilterValue = string.Empty;
                    }
                    else
                    {
                        gc.CurrentFilterFunction = GridKnownFunction.EqualTo;
                        gc.CurrentFilterValue = rcbFilter.SelectedValue;
                    }

                    // Apply the column filter
                    this.RadGrid1.Rebind();

                    // Column found, break from the loop
                    break;
                }
            }

[Gunjan]

I figured out how to do it. I'm using the FireCommandEvent() to filter the custom drop-down filter. Please let me know if this is a suitable method. Also, I'm comparing the "DataValueField" with the "UniqueName", but was wondering if there is a better method.

Thanks for the help,

Gunjan

I am getting an error:

When I try to change index on the filter template of RadComboBox on server side.

However, if I use client side script, I get following error:
Selection out of range Parameter name: value.

I need help.

I've moved my filtering to client-side with help from telerik support. Make sure you set the column of the FilterIndexChanged() function to the DataValueField of the radcombobox.

Hope this helps,

But the above event does not fire.  Am I missing something?

Please Disregard the last post. I found my error.  I was using OnClientSelectedIndexChanged vs. OnSelectedIndexChanged. 
Thanks, Pete

Hi Pete,

I am glad that you could solve the problem on your own.
