Hi, very basic question for noob, I searched & tried to find someone just doing a basic gridview row save...thing

I have a RadGridView bound to a  SQL database

I am wondering what the generally accepted method is, of updating a row to the database?

A button to fire off an update statement?

 

Thanks,

Rich

Greetings,

Is there any StartMenu event such as clicking event to control?

As it isn't considered a ribbonbar's tab, it can not be controlled using tab events.

 

Greetings,

I have a Radlistview, a Textbox, and a Button. User enters a decimal or non-decimal number in the Textbox (For example, 3.1) and clicks the button.

Here is the clicking event of the button :

 

I did a test :

1- Adding the first item to RadlistView with textbox value set to 20.

2- Adding the Second item to RadlistView with textbox value set to 2.1.

 

As sorting direction is set to Ascending (also tested with descending), 2.1 should be placed as the first item because it is smaller than 20. But it doesn't work.

I appreciate any solution to this issue. Thanks

 

 

How to create gridviewtemplate dynamically in winforms?

The sample code below is with statically created gridviewtemplate, how to make it dynamically with 'n' number of gridviewtemplate from code?

            radGridView1.DataSource = dt;

            GridViewTemplate firstChildtemplate = new GridViewTemplate();
            firstChildtemplate.DataSource = dt1;
            radGridView1.MasterTemplate.Templates.Add(firstChildtemplate);

            GridViewRelation relation = new GridViewRelation(radGridView1.MasterTemplate);
            relation.ChildTemplate = firstChildtemplate;
            relation.RelationName = "HeaderDetails";
            relation.ParentColumnNames.Add("HeaderID");
            relation.ChildColumnNames.Add("ParentHeaderID");
            radGridView1.Relations.Add(relation);


            GridViewTemplate secondChildtemplate = new GridViewTemplate();
            secondChildtemplate.DataSource = dt2;
            firstChildtemplate.Templates.Add(secondChildtemplate);

            GridViewRelation relation2 = new GridViewRelation(firstChildtemplate);
            relation2.ChildTemplate = secondChildtemplate;
            relation2.RelationName = "CAPFieldDetails";
            relation2.ParentColumnNames.Add("HeaderID");
            relation2.ChildColumnNames.Add("ParentHeaderID");
            radGridView1.Relations.Add(relation2);

Hello,

 Am using Rad grid view with Multi column combo box.

 I created a Column type as GridViewMultiComboBoxColumn, attached the data source, also included the displaymember, valuemember,dropdwonstyle as RadDropDownStyle.DropDown. and added the column to the grid.

I am facing a problem that if i type in the  GridView MultiComboBox Column, the control is not filtering and showing result.

I got a documentation  saying

The drop-down element is an object of type MultiColumnComboBoxElement. Use this element to set the drop-down style, animation and sizing as you would do for the regular combobox.  
The EditorControl property of the MultiColumnComboBoxElement gives you a reference to the RadGridView control. Using that reference you can obtain the RadGridView object and work as with normal RadGridView control. Refer to RadGridView documentation for additional information on RadGridView.

The current version has one limitation that you should consider:
You cannot use the auto-complete mode of RadDropDownList
The RadGridView control hosted in the drop-down does not allow editing operations
The RadGridView control hosted in the drop-down does not support filtering, grouping and sorting operations.

kindly confirm me is it a limitation or do i need to include something else in my code.

I am including the code snip shot for your ref. 

bool isColumnAdded=false; 

private void Form1_Load(object sender, EventArgs e)
        {
            filldata();​

     }

 

private void filldata()
        {
            SqlCommand cmmdata = new SqlCommand();
            cmmdata.Connection = constkbal;
            cmmdata.CommandText = "select top 50 stockno from itemmaster";
            SqlDataReader srdtls = cmmdata.ExecuteReader();
            DataTable dtdetails = new DataTable();
            dtdetails.Load(srdtls);
            srdtls.Close();
            GridViewMultiComboBoxColumn col = new GridViewMultiComboBoxColumn();
            col.DataSource = dtdetails;
            col.DisplayMember = "stockno";
            col.ValueMember = "stockno";
            col.FieldName = "stockno";
            col.HeaderText = "stockno";
            col.Width = 400;
            col.DropDownStyle = RadDropDownStyle.DropDown;
            col.FilteringMode = GridViewFilteringMode.DisplayMember;
            
            this.griditemdisplay.Columns.Add(col);
     }

private void griditemdisplay_CellBeginEdit(object sender, GridViewCellCancelEventArgs e)
        {
            if (this.griditemdisplay.CurrentColumn is GridViewMultiComboBoxColumn)
            {
                if (!isColumnAdded)
                {
                    isColumnAdded = true;
                    RadMultiColumnComboBoxElement serchengineElement = (RadMultiColumnComboBoxElement)this.griditemdisplay.ActiveEditor;
                    serchengineElement.DropDownSizingMode = SizingMode.UpDownAndRightBottom;
                    serchengineElement.DropDownMinSize = new Size(550, 300);
                    serchengineElement.DropDownMaxSize = new Size(550, 300);
                    serchengineElement.EditorControl.MasterTemplate.AutoGenerateColumns = false;
                    serchengineElement.AutoCompleteMode = System.Windows.Forms.AutoCompleteMode.SuggestAppend;
                    serchengineElement.AutoSizeDropDownToBestFit = false;
                    serchengineElement.DropDownAnimationEnabled = false;
                    serchengineElement.EditorControl.Columns.Add(new GridViewTextBoxColumn("Stockno"));
                    FilterDescriptor filtercustomername = new FilterDescriptor("Stockno", FilterOperator.Contains, string.Empty);
                    serchengineElement.EditorControl.FilterDescriptors.Add(filtercustomername);

                }
            }

        }​​

 

 

 

 

 

Is it possible to have a custom shaped screen tip? 

I have created a custom screen tip class, set the Shape property of the element to be a shape and it appears to work visually but it's leaving a grey background in the spots where I want it to be transparent. See attached. 

 

I have also tried doing the same but with an image, making the background of the image transparent, but the same thing happens. 

 

Thanks. 

 

 

Hello, Is it possible to merge a commandbar from a child with the parent commandbar?

Hello,

I have a DocumentWindow (part of a RadDock) which has a FlowLayoutPanel inside of it set to Dock Fill.  The FlowLayoutPanel has the FlowDirection set to "TopDown".

Inside the FlowLayoutPanel I want to have full width Panels.  The Panels themselves are meant to act as containers for "comment boxes" which will are to be stacked vertically in the DocumentWindow (see poor ascii art below).  I've set the Panel "Anchor" property to "Left-Right" but the Panels will not expand to fit the entire FlowLayoutPanel.

My questions are:

1.  Should this work?
2.   If not, what is a good way to do this type of layout?

Thank you!

Best Regards,

Ed


Here is what I'm trying to acheive (the box made of '+' signs is the FlowLayoutPanel which is inside of a DocumentWindow)

In a RadMap I have several layers with each layer showing a different category of items, each with its own colored icon. 
For each layer I would like to change the color of the round icon containing the number of elements per cluster, is this possible? 
I would have expected a Behavior property on each MapLayer object,

 

I'd like to position a Shape's text outside of the shape itself. Can this be accomplished?

Initially I thought I might have to have a separate Label shape associated with every shape, to achieve this. I also need to apply alignment, e.g. left, center, right, so perhaps a separate Label shape would be better, then group it with its shape (as they are inseparable).
