fill gridview cell-by-cell
- by raging_boner
I want to populate GridView below with images:
<asp:GridView ID="GrdDynamic" runat="server" AutoGenerateColumns="False">
<Columns>
</Columns>
</asp:GridView>
The code below iterates through directory, then I collect image titles and want them to be populated in gridview. code in bold is not working well, gridview is only filled with the last image in list.
List<string> imagelist = new List<string>();
protected void Page_Load(object sender, EventArgs e)
{
foreach (String image in Directory.GetFiles(Server.MapPath("example/")))
{
imagelist.Add("~/example/" + Path.GetFileName(image));
}
loadDynamicGrid(imagelist);
}
private void loadDynamicGrid(List<string> list)
{
DataTable dt = new DataTable();
DataColumn dcol = new DataColumn(NAME, typeof(System.String));
dt.Columns.Add(dcol);
dcol = new DataColumn("NAME1", typeof(System.String));
dt.Columns.Add(dcol);
dcol = new DataColumn("NAME2", typeof(System.String));
dt.Columns.Add(dcol);
dcol = new DataColumn("NAME3", typeof(System.String));
dt.Columns.Add(dcol);
DataRow drow = dt.NewRow();
dt.Rows.Add();
dt.Rows.Add();
**for (int i = 0; i < dt.Rows.Count; i++)
{
for (int j = 0; j < dt.Columns.Count; j++)
{
foreach (string value in list)
{
dt.Rows[i][j] = value;
}
}
}**
foreach (DataColumn col in dt.Columns)
{
ImageField bfield = new ImageField();
bfield.DataImageUrlField = NAME;
bfield.HeaderText = col.ColumnName;
GrdDynamic.Columns.Add(bfield);
}
GrdDynamic.DataSource = dt;
GrdDynamic.DataBind();
}
how to fill gridview cell-by-cell only with available amount of images?
i know it is easy, i tried various methods like: dt.Rows.Add(list); and some other attempts, but they didn't work. i'm very stupid.
i'd be glad for any help.
