asp.net Gridview does not display

I try to bind my list of objects to my datasource.
But as I switched from autogeneratecolums to boundfields, the whole grid is not displayed anymore.
Is there something I miss to let this work proper?
asp:
<asp:GridView ID="grid_article"
AutoGenerateColumns="false"
runat="server"
GridLines="None"
AllowPaging="true"
CssClass="mGrid"
PagerStyle-CssClass="pgr"
AlternatingRowStyle-CssClass="alt"
OnPageIndexChanging="ArticleGrid_PageIndexChanging">
<Columns>
<asp:TemplateField HeaderText="Select">
<ItemTemplate>
<asp:CheckBox ID="cbSelect" runat="server" ReadOnly="false"></asp:CheckBox>
</ItemTemplate>
</asp:TemplateField>
<asp:BoundField DataField="itemNumber" HeaderText="Product Number" ReadOnly="true"></asp:BoundField>
<asp:BoundField DataField="name" HeaderText="Product Name" ReadOnly="true"></asp:BoundField>
<asp:BoundField DataField="description" HeaderText="Product Description" ReadOnly="true"></asp:BoundField>
<asp:BoundField DataField="purchasePrice" HeaderText="Purchase Price" ReadOnly="true"></asp:BoundField>
<asp:BoundField DataField="salesPrice" HeaderText="Sales Price" ReadOnly="true"></asp:BoundField>
</Columns>
</asp:GridView>
code behind:
if (articles != null)
{
if (articles.Count != 0)
{
DataTable dt = new DataTable();
dt.Columns.Add("itemNumber");
dt.Columns.Add("name");
dt.Columns.Add("description");
dt.Columns.Add("purchasePrice");
dt.Columns.Add("salesPrice");
foreach (AccessoryDTO item in articles)
{
DataRow dr = dt.NewRow();
dr["itemNumber"] = item.itemNumber;
dr["name"] = item.name;
dr["description"] = item.description;
dr["purchasePrice"] = item.purchasePrice + " " + item.currency;
dr["salesPrice"] = item.salesPrice + " " + item.currency;
dt.Rows.Add(dr);
}
grid_article.DataSource = dt;
show_record_count(articles.Count);
grid_article.DataBind();
}
else
{
grid_article.DataSource = null;
grid_article.DataBind();
}
}

try like this code that i worked with in sharepoint 2013 :

How can I add a row above the BoundField in ASP.NET GridView [duplicate]

Closed 7 years ago.
I want to add a row above the BoundField. This is my GridView:

<RowStyle HorizontalAlign="Left" VerticalAlign="Top" />
<SelectedRowStyle HorizontalAlign="Left"></SelectedRowStyle>
</asp:GridView>
At the moment it looks like that, but now I want to add a row above:
It should look like that, how can I add a row above the BoundField HeaderText?
I would like to do it right in the aspx file if it's even possible.

I made a method inside the codebehind.
This is my code now and it works.
protected void grdvProductChurn_RowCreated(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.Header)
{
GridView HeaderGrid = (GridView)sender;
GridViewRow HeaderGridRow = new GridViewRow(0, 0, DataControlRowType.Header, DataControlRowState.Insert);
TableCell HeaderCell = new TableCell();
HeaderCell.Text = "";
HeaderCell.ColumnSpan = 2;
HeaderGridRow.Cells.Add(HeaderCell);
HeaderCell = new TableCell();
HeaderCell.Text = "Anzahl";
HeaderCell.ColumnSpan = 6;
HeaderGridRow.Cells.Add(HeaderCell);
grdvProductChurn.Controls[0].Controls.AddAt(0, HeaderGridRow);
}
}

You can try it with this example :
protected void HeaderTest(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.Header)
{
GridView HeaderGrid = (GridView)sender;
GridViewRow HeaderGridRow = new GridViewRow(0, 0, DataControlRowType.Header, DataControlRowState.Insert);
TableCell HeaderCell = new TableCell();
HeaderCell.Text = "Test";
HeaderCell.ColumnSpan = 6;
HeaderGridRow.Cells.Add(HeaderCell);
HeaderCell = new TableCell();
HeaderCell.Text = "Test1";
HeaderCell.ColumnSpan = 4;
HeaderGridRow.Cells.Add(HeaderCell);
grdvProductChurn.Controls[0].Controls.AddAt(0, HeaderGridRow);
}
}
From : How to add Header and Subheader in Gridview

You can add it like following-
protected void Page_Load(object sender, EventArgs e)
{
DataTable dt = new DataTable();
DataColumn dc = new DataColumn();
if (dt.Columns.Count == 0)
{
dt.Columns.Add("Produktgruppe", typeof(string));
dt.Columns.Add("Produkt", typeof(string));
dt.Columns.Add("Jan", typeof(string));
dt.Columns.Add("Feb", typeof(string));
dt.Columns.Add("March", typeof(string));
dt.Columns.Add("may", typeof(string));
dt.Columns.Add("Jun", typeof(string));
}
DataRow NewRow = dt.NewRow();
NewRow[0] = " ";
NewRow[1] = "Anzahl";
dt.Rows.Add(NewRow);
GridView1.DataSource = dt;
GridViewl.DataBind();
}
I hope this can help you.

for (int k = 1; k <= dt.Rows.Count; k++)
dr[k] = dt.Rows[k - 1][j];
dtnew.Rows.Add(dr);

I guess you need to swap the rows and columns of Datatable.
If that is what you need then please refer this link. It will help you

set values to TextBox in Item template of gridview

I'm working with Outward Challan Detail, in which I need to show the results on a form by a gridview.
My problem is that I don't know how to assign values to textbox existing in the gridview.
How could I assign values in the textbox inside my templates fields that are in my gridview by using dataReader or DataSet?

}
}

You should directly bind the DataTable Column to TextBox inside the TemplateField like...
<asp:TextBox ID="txtDispatchQuantity" runat="server" Text='<%# Eval("ColumnNameInDataSetTable") %>' />
This directly binds the values to TextBoxes. You can do this for all other TextBoxes.

TextBox txtDispatchQuantity = (TextBox)e.Row.FindControl("txtDispatchQuantity");
var dataRow = (DataRowView)e.Row.DataItem;
var Dispatch_Qty = "Dispatch_Qty";
var check = dataRow.Row.Table.Columns.Cast<DataColumn>().Any(x => x.ColumnName.Equals(Dispatch_Qty, StringComparison.InvariantCultureIgnoreCase));
if (check)
{
// Property available
txtDispatchQuantity.Text =ds1.Tables[0].Rows[0][7].ToString();
}

protected void gvOutDCItemDetails_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
//if ((e.Row.RowState & DataControlRowState.Edit) > 0)
//{
DropDownList ddList = (DropDownList)e.Row.FindControl("ddrProcess");
//bind dropdownlist
SqlCommand cmd = new SqlCommand("sp_getProcess", con1);
cmd.CommandType = CommandType.StoredProcedure;
SqlDataAdapter da = new SqlDataAdapter(cmd);
DataSet ds = new DataSet();
da.Fill(ds);
DataTable dt = ds.Tables[0];
//DataTable dt = con1.GetData("Select category_name from category");
ddList.DataSource = dt;
ddList.DataTextField = "PName";
ddList.DataValueField = "Process_Id";
ddList.DataBind();
ddList.Items.Insert(0,new ListItem("--SELECT--","0"));
TextBox txtDispatchQuantity = (TextBox)e.Row.FindControl("txtDispatchQuantity");
var dataRow = (DataRowView)e.Row.DataItem;
var Dispatch_Qty = "Dispatch_Qty";
var check = dataRow.Row.Table.Columns.Cast<DataColumn>().Any(x => x.ColumnName.Equals(Dispatch_Qty, StringComparison.InvariantCultureIgnoreCase));
if (check)
{
// Property available
txtDispatchQuantity.Text =ds1.Tables[0].Rows[0][7].ToString();
}
}
if (e.Row.RowType == DataControlRowType.Footer)
{
// Label lblTotalPrice = (Label)e.Row.FindControl("Total_Amount");
//lblTotalPrice.Text = total.ToString();
// txttotalAmount.Text = Total.ToString();
}
}

A short way with Simple and Inner Select, For use in ASPX code with no Code Behind:
....
<ItemTemplate>
<tr>
<td>
<asp:Label ID="Label1" runat="server" Text='<%# Eval("COrder") %>' />
</td>
<td>
<asp:Label ID="TitleLabel" runat="server" Text='<%# Eval("CText") %>' />
</td>
<td>
Delete
</td>
</tr>
</ItemTemplate>
....
<asp:SqlDataSource ID="SqlDataSource2" runat="server" ConnectionString="<%$ ConnectionStrings:ConnectionString %>" SelectCommand="SELECT [RId],[CId],[COrder],[CText]=(SELECT [Title] from [Categories] where [ID]=[HomeProduct].[CId]) FROM [HomeProduct] ORDER BY [COrder] DESC"></asp:SqlDataSource>

Gridview bound to datatable edit dropdownlist C#

I have a GridView that is bound to a DataTable, and when you select edit, I can get the values to change. However, one field needs to be a dropdownlist and not a textbox. Here's the code I have so far.
protected void griditems_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
DataTable dt = (DataTable)Session["table"];
//Update the values.
GridViewRow row = griditems.Rows[e.RowIndex];
dt.Rows[row.DataItemIndex]["Part"] = ((TextBox)(row.Cells[1].Controls[0])).Text.ToUpper();
dt.Rows[row.DataItemIndex]["Quantity"] = ((TextBox)(row.Cells[2].Controls[0])).Text;
dt.Rows[row.DataItemIndex]["Ship-To"] = ((TextBox)(row.Cells[3].Controls[0])).Text.ToUpper();
dt.Rows[row.DataItemIndex]["Requested Date"] = ((TextBox)(row.Cells[4].Controls[0])).Text;
//dt.Rows[row.DataItemIndex]["Shipping Method"] = ((TextBox)(row.Cells[5].Controls[0])).Text;
DropDownList cmbType = (DropDownList)griditems.Rows[e.RowIndex].FindControl("Shipping Method");
griditems.EditIndex = -1;
BindData();
}
}
When I uncomment the line for the shipping method to be a textbox, it does just as it says, a textbox, not a dropdownlist. I have tried changing it to a DropDownList with no luck.
In the aspx file:
<asp:GridView ID="griditems" runat="server"
onrowdeleting="griditems_RowDeleting" onrowediting="griditems_RowEditing"
onrowupdating="griditems_RowUpdating" AllowPaging="True" onpageindexchanging="griditems_PageIndexChanging"
onrowcancelingedit="griditems_RowCancelingEdit" ViewStateMode="Enabled" Caption="Order Details"
AutoGenerateDeleteButton="True" AutoGenerateEditButton="True"
onrowdatabound="griditems_RowDataBound" >
<EditRowStyle BackColor="#FF9900" BorderStyle="Double" /></asp:GridView>
and when the table is generated:
public void CreateTable()
{
DataTable table = new DataTable();
if (Session["table"] != null)
table = (DataTable)Session["table"];
else
{
table.Columns.Add("Part", typeof(string));
table.Columns.Add("Quantity", typeof(Int32));
table.Columns.Add("Ship-To", typeof(string));
table.Columns.Add("Requested Date", typeof(string));
table.Columns.Add("Shipping Method", typeof(string));
}

ScreenShot:

you can go ahead with the help of this:
dt.Rows[row.DataItemIndex]["Shipping Method"] = ((DropDownList)row.FindControl("DropdownList1")).SelectedItem;
EDIT:
dt.Rows[row.DataItemIndex]["Shipping Method"] = ((DropDownList)
(row.Cells[5].Controls[0])).SelectedItem.ToString();
