How would I go about adding a select all checkboxes header element to a check box column?  I'd settle for a button at this point as well.

Thanks,

I am manually building a radgridview with a childgridview with custom objects but I am not clear on how to retrieve the child rows value on press of a button.  I am adding a decimal column that I want to retrieve the user input.

Below is the code that populated the radgridview.

Thanks.



BindingList<LoadLine> loadLines = new BindingList<LoadLine>();
            BindingList<PartLocation> partLocations = new BindingList<PartLocation>();

GridViewTemplate locationsTemplate = new GridViewTemplate(this.radGridViewLoadDetailLoadLines);
                locationsTemplate.AutoGenerateColumns = false;

                #region Manually Add Columns for Child Table

                GridViewDataColumn columnPartId = new GridViewDataColumn();
                columnPartId.UniqueName = "PartId";
                columnPartId.FieldAlias = "PartId";
                columnPartId.FieldName = "PartId";
                locationsTemplate.Columns.Add(columnPartId);

                GridViewDataColumn columnLocationId = new GridViewDataColumn();
                columnLocationId.UniqueName = "LocationId";
                columnLocationId.FieldAlias = "LocationId";
                columnLocationId.FieldName = "LocationId";
                locationsTemplate.Columns.Add(columnLocationId);

                GridViewDataColumn columnAvailableQty = new GridViewDataColumn();
                columnAvailableQty.UniqueName = "AvailableQty";
                columnAvailableQty.FieldAlias = "AvailableQty";
                columnAvailableQty.FieldName = "AvailableQty";
                locationsTemplate.Columns.Add(columnAvailableQty);

                GridViewDecimalColumn columnQtyToAllocate = new GridViewDecimalColumn();
                columnQtyToAllocate.UniqueName = "QtyToAllocate";
                columnQtyToAllocate.HeaderText = "Qty To Load";
                locationsTemplate.Columns.Add(columnQtyToAllocate);

                #endregion

                locationsTemplate.DataSource = partLocations;
                locationsTemplate.AllowAddNewRow = false;
                locationsTemplate.AllowAutoSizeColumns = true;
                locationsTemplate.AutoSizeColumnsMode = GridViewAutoSizeColumnsMode.Fill;

                this.radGridViewLoadDetailLoadLines.MasterGridViewTemplate.ChildGridViewTemplates.Add(locationsTemplate);
                GridViewRelation relation = new GridViewRelation(this.radGridViewLoadDetailLoadLines.MasterGridViewTemplate);
                relation.RelationName = "Load Line Part Locations";
                relation.ParentColumnNames.Add("PartId");
                relation.ChildColumnNames.Add("PartId");
                relation.ChildTemplate = locationsTemplate;
                this.radGridViewLoadDetailLoadLines.Relations.Add(relation);

this.radGridViewLoadDetailLoadLines.DataSource = loadLines;

Not sure if I'm doing this the wrong way, or if there is a bug in the control, but I can't seem to set the enabled or readonly property to disable text entry for a time.  Is there something I'm doing wrong or a workaround?

I tried
Element.Enabled = false;
Element.TextBoxItem.Enabled = false;
Element.TextBoxItem.ReadOnly = true;
Element.TextBoxItem.HostedControl.Enabled = false;

None seemed to work.

Hello

I am trying to create a toolbar similar to the visual studio toolbox where everything will be in groups.

In visual studio when you right click to add a new group, once added the caption comes up as editable!

Is there a built in way of making the caption editable on the panel bars group element?

Or do you have any suggestions of the best way of going about it?

Thanks

Bex

I have a form using the radRibbonBar and it works fine but I have one annoying problem. In order to make the form look right I need to hide the blue title bar on the form - this means setting the text property to nothing and turning off the control box. The form looks good but the button associated with it that appears in the taskbar has no text in it. I've set the text property of the ribbonbar but this isn't reflected in the button.

Is there a way to set the button text independently of the form?

I've tried setting the text property after the form has loaded but this made no difference.

Thanks for any suggestions,
Martin.

Hello,

I need a help,please. I have some RadComboBoxElements in my RadGridView in sense of previously posted ProgressBarInGrid project. And I have to AddHandler of RadComboBox.DropDownOpened/Closed events, but the RadComboBoxElement has not this events like the normal RadComboBox does. But other RadComboBox events such as SelectedIndexChanged are included and work well. If there is a ellegant way(Because these elements are DropDownList i could handle click_event and check if isdroppeddown but this part solution does not handle if someone open the list and then close it by clicking somewhere on form ) of Handling these events, please post it. Thanks.

Hey guys,

Someone had asked about showing a form in a Carousel or Rotator - don't remember which. Anyway, that got me thinking...hmmmm....though you may not be able to show an entire form in those controls, you can display a RadPanel in those controls. So then it occurred to me that you could create a RadPanel on a different form, then populate the Carousel or Rotator with that panel. This allows you to put the entire contents of the RadPanel from Form2 on Form1.

Here's what I mean....

Consider this:
- Create two forms - Form1 and Form2
- On Form1, add a RadRotator and a button to change rotator pages (button click, radRotator1.Next();)
- On Form2, add two RadPanels and some RadButtons or other rad controls on each panel
- Back on Form1, create these two methods:

private RadPanel GetPanel(Form form, string panelName)
{
  RadPanel panel = (RadPanel)form.Controls[panelName];
  if (panel == null)
  {
    panel = new RadPanel();
    panel.Text = "UNKNOWN PANEL: " + panelName;
  }

  return panel;
}

private void PopulateRotator()
{
  //create instance of Form2
  Form2 form2 = new Form2();

  //get radPanel1 from Form2
  Telerik.WinControls.UI.RadPanel panel = this.GetPanel(form2, "radPanel1");
  radRotator1.RotatorElement.Items.Add(new RadHostItem(panel));

  //get radPanel2 from Form2
  panel = this.GetPanel(form2, "radPanel2");
  //add the second panel to the rotator
  radRotator1.RotatorElement.Items.Add(new RadHostItem(panel));

  radRotator1.OpacityAnimation = true;
  radRotator1.Next();
}
       
       
- Finally, add the Form_Load event in Form1 and call the PopulateRotator() method.

DISCLAIMER: Just an idea. You'll need to add error handling and stuff...and eh...did I mention this was only an idea?!!!!!  :-)

In many applications now, if you click the upper left corner of a grid/table, it will select the entire table.  Is this possible in the GridView?
