Hello

I am using a RadGridview (2012 Q1) and I wanted to know if there was a way to read/validate the group's total after a modification.

Format    Product    Pct
Can    1000    0.2
Can    1001    0.6
Can    1002    0.2
Plas    1003    0.8
Plas    1004    0.2

If a user modifies a percentage, I would like to wait saving to the database until he corrects another product to make sure the total is 100%

I am setting up my Gridview like this:

radGridView1.GroupDescriptors.Add(new GridGroupByExpression("Format Group By Format"));

GridViewSummaryRowItem item1 = new GridViewSummaryRowItem();

item1.Add(new GridViewSummaryItem("pct", "Total: {0:F2} ", GridAggregateFunction.Sum));

In another section of my program, I use radGridView1_CellValidating to save data on a modification (if e.OldValue.ToString() != e.Value.ToString()), but in that case, I didn't need any validation. In this scenario, I do need validation.

Is there a way to use the features of the current gridview to edit directly, or would it be better to build a new form with my format isolated, and fully validating on a button press? Or another workaround I haven't considered?

Thanks.
Philippe

Reset dock layout to designer settings: Best practice?

Hi,

In an MDI environment with (30+) childforms I'd like to be able to reset each child form to the standaard (designer) layout when the end user messed up by eg. hiding tool windows etc.

First of all, saving 60+ XML files (user dock + default dock) to each end user profile is not my preferred option. I saved the default, and the user dock XML to the registry for now, but I'm considering using a table in the database.
However saving/restoring the defaults is a potential bug, because when the app is updated and a form was changed by adding or deleting a tool/document window the "dock.LoadFromXml(dockSettings)" fails, since the xml in the registry reflects the 'old' pre-update form.

So 2 questions:
- Is there a way to reset the dock layout, without the LoadFromXml? That way I would not need to 'remember' the default designer settings. If not, what is the best practice to reset the updated forms in my updated app to the default?
- saving to a table, I would only need to save these 3 columns, or do I mis something?
   - form name
   - Dock XML info
   - UserId for particular settings (or eg. Guid.Empty for the default)

Kind regards,
Raoul

Setting SelectionMode and SortStyle at desing time show false selections in some situations

Hello,

I observed a behavior of RadListControl which shows false results. I could reproduce it with this code:

using System.Windows.Forms;

using Telerik.WinControls.Enumerations;

using Telerik.WinControls.UI;

namespace TestListboxSortAnSelection

{

public partial class Form1 : Form

{

public Form1()

{

InitializeComponent();

this.radListControl1.SelectionMode = SelectionMode.MultiExtended;

this.radListControl1.SortStyle = SortStyle.Ascending;

this.radListControl1.Items.Add(new RadListDataItem("Test 1"));

this.radListControl1.Items.Add(new RadListDataItem("Test 3") { Selected = true });

this.radListControl1.Items.Add(new RadListDataItem("Test 2") { Selected = true });

}

private void radButton1_Click(object sender, System.EventArgs e)

{

MessageBox.Show(string.Concat("Selected items: ",

this.radListControl1.SelectedItems.Count));

}

/// <summary>

/// Required method for Designer support - do not modify

/// the contents of this method with the code editor.

/// </summary>

private void InitializeComponent()

{

this.radListControl1 = new Telerik.WinControls.UI.RadListControl();

this.radButton1 = new Telerik.WinControls.UI.RadButton();

((System.ComponentModel.ISupportInitialize)(this.radListControl1)).BeginInit();

((System.ComponentModel.ISupportInitialize)(this.radButton1)).BeginInit();

this.SuspendLayout();

//

// radListControl1

//

this.radListControl1.CaseSensitiveSort = true;

this.radListControl1.ItemHeight = 18;

this.radListControl1.Location = new System.Drawing.Point(12, 12);

this.radListControl1.Name = "radListControl1";

this.radListControl1.Size = new System.Drawing.Size(431, 312);

this.radListControl1.TabIndex = 0;

this.radListControl1.Text = "radListControl1";

//

// radButton1

//

this.radButton1.Location = new System.Drawing.Point(313, 330);

this.radButton1.Name = "radButton1";

this.radButton1.Size = new System.Drawing.Size(130, 24);

this.radButton1.TabIndex = 1;

this.radButton1.Text = "radButton1";

this.radButton1.Click += new System.EventHandler(this.radButton1_Click);

//

// Form1

//

this.AutoScaleDimensions = new System.Drawing.SizeF(6F, 13F);

this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;

this.ClientSize = new System.Drawing.Size(455, 366);

this.Controls.Add(this.radButton1);

this.Controls.Add(this.radListControl1);

this.Name = "Form1";

this.Text = "Form1";

((System.ComponentModel.ISupportInitialize)(this.radListControl1)).EndInit();

((System.ComponentModel.ISupportInitialize)(this.radButton1)).EndInit();

this.ResumeLayout(false);

}

private Telerik.WinControls.UI.RadListControl radListControl1;

private Telerik.WinControls.UI.RadButton radButton1;

}

If SelectionMode is None, all works fine. Changing to One and SortStyle to Ascending it shows 2 selected items, but only 1 is selected. If SortStyle is Descending and Test 1 and 2 preselected then it shows also 2 selected items with one selected in list. Similar results occures with SelectionMode MultiSimple and MultiExtended. With SortStyle Ascending only 1 item is select on view and list. On SortStyle Descending it changes to 3 items on view and list.

The work around of this bug?! is to set SortStyle after adding the items to Items list (in code, not during design time).

Disable In-Place Editor

Hello,

I'm trying to disable the in-place editor in my RadScheduler (in winforms of course) but i can't find properties that allow this...
I know that it's possible with the Silvelight Telerik components but I can't find such a propertie with WinForms components.
I don't want that my users could create appointments in typing on the keybord.
I already disable the Edit Appointment Form by clicking on cells but i want to disable the in place editor too.
How can I do this ?

Thanks, Celine

No WinForms Update for 2012 Q2?

I was looking at the webinars coming up in June and I noticed that there is not one that includes any discussion of the WinForms controls for the 2012 Q2 release. Does this mean Telerik is ceasing development or enhancement of the WinForms controls?

Force update when checkboxcell value changes

With the RadGridView, if I have a checkboxcolumn and the user clicks on the checkbox, the value is not updated in my datasource (BindingList<> of business objects) until the user clicks off of the row. How can I force the update to happen immediately when they click on the checkbox? ValueChanging and ValueChanged don't seem to update my BindingList when I want them to.

Thanks!
