FilterDescriptors.Expression allways empty

I have this piece of code very similar to the one in the demos but I allways get an empty string from FilterDescriptors.Expression

this.Confecciones.AllowFiltering = true;

this.ConfeccionesGV.FilterChanged += Confecciones_FilterChanged;

void ConfeccionesGV_FilterChanged(object sender, VirtualGridEventArgs e)
        {
            Filter();
        }

        private void Filter()
        {
            string filterExpression = this.ConfeccionesGV.FilterDescriptors.Expression;
            if (!string.IsNullOrEmpty(filterExpression))
                MessageBox.Show(filterExpression);
        }

RadAutoCompleteBox

Hi,

Is there any way to allow RadAutoCompleteBox auto suggestion item to select only unique items. For example, RadAutoCompleteBox has item A, item B and item C. I don't want user to choose Item A two times. Would like to remove previously selected item from auto suggestion list. For example Item A is already in the RadAutoCompleteBox.Items collection, want to show only item B and C in auto complete suggestion box. If not possible to do that, want to cancel the selection if existing item is selected again. Is it possible to do that?

Printing Radtree Nodes

Greetings,

I'm looking for VB.NET solutions to print Radtree content. I found some relevant threads :

How to Print

Printing RadTree content

But no success for me yet to implement any of the suggested methods . Is there any actual implementation of printing Radtree in VB.net as a sample code or project that demonstrates the printing method of RadTree content?

I also thought of Word automation in order to create a similar tree in Office word (using bulleted list) and then print the document, as Radtree nodes could be alternatives to bullets in Office Word's bulleted list.

Auto Scrolling When Performing Drag and Drop between GridViews

I've implemented drag and drop between two RadGridViews using RadGridViewDragDropService.

This works well, but I can't get Auto Scrolling to work when dragging from one gridview to another. It does work if I drag within the same gridview.

I do have AllowAutoScrollRowsWhileDragging set to true.

What could I be doing wrong?

RadGridView - Filter Programatically

I am using Q1 2008 Winforms

I have looked at the other threads relating to this issue and they either dead end or reference methods/properties that are no longer available.

I populated my RadGridView via DataSet
I also populate numerous comboboxes with that same Dataset.

I desire to select to select a combobox, choose an item within the combobox and on selectedindex changed filter the RadGridView accordingly.
I also want to be able to select as many comboboxes as i'd like to continuously filter down the RadGridView.

I cannot seem to find valid code for setting the filter expression programatically.

Please advise.

Context Menu Closing problem

Hello all,

My problem is this: I have a drop down list inside of a context menu. When the selected index changes, I want to open that specific page view (handled by GoToWindow() method) and close the drop down and the parent context menu.

However, I can't figure out a way to have the context menu know when I am clicking on something in the child DropDownList element.

Here's my code for the context menu opening:

private void MPLList_GridView_ContextMenuOpening(object sender, ContextMenuOpeningEventArgs e)

{

List<BPPriceMstr> myBP = new List<BPPriceMstr>();

FactoryOrder bpOrder = new FactoryOrder();

int index = MPLList_GridView.Rows.IndexOf(MPLList_GridView.CurrentRow);

bpOrder.AddOrderLine("CardCode", masterPriceLists[index].Business.CardCode);

BPPriceMstrFactory bpFactory = new BPPriceMstrFactory();

tmpDDL_MPLLists = bpFactory.BuildPriceMstr(bpOrder);

/////////////////////////////

//new code -- RRM and BRA

/////////////////////////////

//create empty drop down list

RadDropDownList mplDropDownList = new RadDropDownList();

mplDropDownList.Text = "Select MPL";

//iterate over all MPLs and add them to the drop down list

foreach (BPPriceMstr mpl in tmpDDL_MPLLists)

{

mplDropDownList.Items.Add(new RadListDataItem(mpl.StartDate.ToShortDateString() + " - " + mpl.EndDate.ToShortDateString()));

}

//add selected index changed event handler

mplDropDownList.SelectedIndexChanged += mplDropDownList_SelectedIndexChanged;

//create content item for drop down list

RadMenuContentItem contentItem = new RadMenuContentItem();

RadHostItem host = new RadHostItem(mplDropDownList);

//populate the drop down list

contentItem.ContentElement = host;

//set the size of the MPL drop down menu

contentItem.AutoSize = false;

contentItem.Size = new System.Drawing.Size(150, 100);

//here we add an arrow to select MPL from the drop down list.

//if only one MPL, there will be only one to choose from

RadMenuItem mplSpecific = new RadMenuItem();

mplSpecific.Text = "Open Specific Master Price List";

mplSpecific.Items.Add(contentItem);

RadMenuSeparatorItem separator = new RadMenuSeparatorItem();

e.ContextMenu.Items.Add(separator);

e.ContextMenu.Items.Add(mplSpecific);

}

Then, here is my method for when the selected index is changed for the drop down:

private void mplDropDownList_SelectedIndexChanged (object sender, Telerik.WinControls.UI.Data.PositionChangedEventArgs e)

{

//this method gets called whenever the DDL index is changed

//i.e. whenever a user selects a different MPL date range

RadDropDownList list = sender as RadDropDownList;

if(list != null && e.Position > -1)

{

//Console.WriteLine("New Selected Item: " + list.Items[e.Position]);

//get the mpl id for the MPL date range selected

int mplid = tmpDDL_MPLLists[e.Position].Id;

FactoryOrder myOrder = new FactoryOrder();

//create an order tuple to open the specific MPL page we want to view

myOrder.AddOrderLine("SpecificList", mplid.ToString());

//jump manager to pull up a specific MPL window tab

JumpOrder myJumpOrder = new JumpOrder();

myJumpOrder.factoryOrder = myOrder;

myJumpOrder.module = "MPL";

myJumpOrder.targetWin = "MPLS";

//issue: new MPLS tab should have date range populated

MainDockWin.mainJumpManager.PassJumpOrder(myJumpOrder);

MainDockWin.mainJumpManager.GoToWindow();

}

//need a way to hide the parent menu when sub-menu item is clicked and we jump...

//list.Visible = false;

//this only hides the MPL drop down list...

//how to hide the context menu?

//list.Parent.Visible = false;

//let the context menu know that there was a click...and close

list.Parent.Hide();

}

The list.Parent.Hide (or set Visible=false) only hides the drop down menu, not the overall context menu. list.Parent.Parent returns null. Any and all help is appreciated! Thanks

See attached screenshot for what I'm referring to as the behavior of my program.
