I ask this question because I think I have different problem with this : How to hide gridview column after databind?
My gridview has data from database. I don't set any "td" in my code, but html changes the gridview to table and have "td". The problem is, I don't want the cell or "td" is shown on the page, I just want to receive the data in the cell to show the image in the database.
This is code to retrieve data from database:
public static DataTable FetchAllImagesInfo(int id)
{
string sb = "Select img_content, Img_id, csrid FROM images WHERE Img_Id = " + id + ";";
SqlConnection conn = DatabaseFactory.GetConnection();
SqlDataAdapter da = new SqlDataAdapter(sb, conn);
DataTable dt = new DataTable();
da.Fill(dt);
return dt;
}
This is codebehind to bind GridView, here I tried to set Visible to true or false, but it doesn't work. I set column index manually because it's only has 3 column :
GridView1.DataSource = ProductAllLocationCatalog.FetchAllImagesInfo(_id);
GridView1.DataBind();
GridView1.Columns[0].Visible = true;
GridView1.Columns[1].Visible = false;
GridView1.Columns[2].Visible = false;
And, this is my aspx code :
<asp:GridView ID="GridView1" runat="server">
<Columns>
<asp:TemplateField runat="server">
<ItemTemplate runat="server">
<asp:Image ID="image1" runat="server" ImageUrl='<%#"Handler.ashx?csrid="+Eval("csrid") %>' style="max-height:400px; max-width:940px; text-align:center; margin:auto; display:block;" />
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
I just need the image from the database, not other. But if I only SELECT the image, gridview can not do DataBind(), and I can't get value of "csrid".
Thank you!
