dynamic row in radgrid

[Ali Uğur]

Hi there,

I have a radgrid which is created dynamically in C#. Now I want to add a new dynamic row which should be different in every row. I have managed adding a new link coloumn, however it seems same in every row.

Here is the code;

        public void Gridi_Getir()
        {
            DataSet musteriDataSet = new DataSet();
            musteriDataSet = bllMusteri.MusteriGetir();
            DataView musteriDataView = musteriDataSet.Tables["Musteriler"].DefaultView;
            RadGrid1.DataSource = musteriDataView;

            for (int i = 0; i < musteriDataView.Count; i++)
            {
                dtoMusteri musteri = new dtoMusteri();
                musteri.MusteriID = Convert.ToInt32(musteriDataView[i].Row.ItemArray[0]);
                HesapKartlariniGetir(musteri, i);
            }

            RadGrid1.DataBind();
        }

        public void HesapKartlariniGetir(dtoMusteri musteri, int k)
        {
            ArrayList hesapKartlari = bllMusteriHesapKarti.MusteriIDyeGoreMusteriHesapKartiGetir(musteri.MusteriID);

            for (int i = 0; i < hesapKartlari.Count; i++)
            {
                //TableCell cell = new TableCell();

                //cell.Text = ((CoalSoft.DTO.dtoMusteriHesapKarti)(hesapKartlari[i])).MusteriHesapKartiAdi;

                GridHyperLinkColumn column = new GridHyperLinkColumn();
                //column.InitializeCell(cell, i, RadGrid1.Items[k]);
                column.ItemStyle.Font.Name = "Tahoma";
                column.Text = ((CoalSoft.DTO.dtoMusteriHesapKarti)(hesapKartlari[i])).MusteriHesapKartiAdi;
                column.NavigateUrl = "MusteriHesapKartiDetay.aspx?MusteriHesapKartID=" + ((CoalSoft.DTO.dtoMusteriHesapKarti)(hesapKartlari[i])).MusteriHesapKartiID;

                RadGrid1.Columns.Insert(i + 4, column);
            }
        }

Thanks.

Any ideas?

Hello Ali,

You can add a GridTemplateColumn to your grid and initialize a customizable ITemplate object for the ItemTemplate of the column. Using the DataBinding event of the controls in the template, you can get a reference to the GridDataItem instance for which the template is initialized. There, you can customize your controls as much as you need based on item data values:

public class MyGridTemplateColumnTemplate : ITemplate

{

    #region ITemplate Members

 

    public void InstantiateIn(Control container)

    {

        TextBox textBox = new TextBox();

        textBox.ID = "TextBox1";

        textBox.DataBinding += new EventHandler(textBox_DataBinding);

        container.Controls.Add(textBox);

    }

 

    void textBox_DataBinding(object sender, EventArgs e)

    {

        TextBox textBox = (TextBox)sender;

        GridDataItem item = (GridDataItem)item.NamingContainer;

        int itemId = (int)DataBinder.Eval(item.DataItem, "ID");

        //In this way, you can access data values and customize

        //the control firing DataBinding event for each cell

    }

 

    #endregion

}


This is the general approach in customizing databound controls in template columns. If you give us some more details on what exactly is your scenario and what you need to implement, we might be able to suggest a more specific approach.
