RadGridView Rows.AddNew() problem

[Bugra]

Hi everyone,

I'm trying to make a datagrid which allows custom components into cells. But when I call AddNew void, it gives me an error like this;

Constructor on type 'FCS.ManagementConsole.Main.Components.ucTextButtonElement' not found.

Here is my ucGridViewTextButtonCellElement.cs;

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using Telerik.WinControls.UI;
using Telerik.Reporting.Drawing;
using System.Drawing;

namespace FCS.ManagementConsole.Main.Components
{
    class ucGridViewTextButtonCellElement : GridDataCellElement
    {
        private ucTextButtonElement TextBoxButtonElement;
        public ucGridViewTextButtonCellElement(GridViewColumn column, GridRowElement row)
            : base(column, row)
        {
        }
        public override void Initialize(GridViewColumn column, GridRowElement row)
        {
            base.Initialize(column, row);
        }
         protected override Type ThemeEffectiveType
        {
            get
            {
                return typeof(GridDataCellElement);
            }
        }
         protected override void CreateChildElements()
         {
             base.CreateChildElements();
             TextBoxButtonElement = new ucTextButtonElement();
             TextBoxButtonElement.MinSize = new Size(50, 20);
             TextBoxButtonElement.Text = "Red";
             this.Children.Add(TextBoxButtonElement);
         }
    }
}

Here is my component class;

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using Telerik.WinControls.UI;

namespace FCS.ManagementConsole.Main.Components
{
    class ucTextButtonElement:RadTextBoxElement
    {
        public event EventHandler ButtonClick;
        public ucTextButtonElement()
        {
            RadButtonElement btn = new RadButtonElement();


            btn.Size = new System.Drawing.Size(25, 10);

            btn.Click += new EventHandler(btn_Click);

            btn.BringToFront();


            btn.Text = "...";

        }

        void btn_Click(object sender, EventArgs e)
        {
            EventHandler handler = ButtonClick;
            if (handler != null) handler(this, e);
        }
    }
}

Here is my ucGridViewTextBoxButtonColumn2.cs;

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using Telerik.WinControls.UI;

namespace FCS.ManagementConsole.Main.Components
{
    class ucGridViewTextBoxButtonColumn2 : GridViewDataColumn
    {
        public ucGridViewTextBoxButtonColumn2(string fieldName)
            : base(fieldName)
        {
        }
           public override Type GetCellType(GridViewRowInfo row)
        {
            if (row is GridViewDataRowInfo)
            {
                return typeof(ucTextButtonElement);
            }
            return base.GetCellType(row);
        }
    }
}

This the code that i get error;

     ucGridViewTextBoxButtonColumn2 grid = new ucGridViewTextBoxButtonColumn2("TextBoxColumn");
 radGridView1.Columns.Add(grid);

  radGridView1.Rows.AddNew();

Do you have any ideas?

Hello Bugra,

The problem is here:

public override Type GetCellType(GridViewRowInfo row)
{
    if (row is GridViewDataRowInfo)
    {
        return typeof(ucGridViewTextButtonCellElement);
    }

    return base.GetCellType(row);
}

Here instead of giving the CellType you have specified the elements type.

Hope this helps, if you have any other questions or comments, please let me know,
