Regarding you case, you need to do the following:
When getting the DataRow, you need to cast it to Byte[] and convert it to a Base64 string like this:
dr["ImageFile"] = Convert.ToBase64String((Byte[])ds.Tables[0].Rows[0]["ImageFile"]);
Once you have the Base64 string, then you can apply it to your control like this:
<img src='data:image/jpg;base64, <%# Eval("ImageFile")%>' />

On deleting the Row of GridView not working properly

Whenever I delete a row from the gridview which I select to delete, the row above to the selected row gets deleted. Dont know why. Please see my code for deleting.

Code behind for your ref:-
protected void grdPostData_RowDeleting(object sender, GridViewDeleteEventArgs e)
{
bool IsDeleted = false;
int Id = Convert.ToInt32(grdPostData.DataKeys[e.RowIndex].Value.ToString());
using (SqlConnection conn = new SqlConnection(System.Configuration.ConfigurationManager.ConnectionStrings["DefaultCSRConnection"].ConnectionString))
{
using (SqlCommand cmd = new SqlCommand())
{
cmd.CommandText = "DELETE FROM tbl_Post WHERE Id=#Id";
cmd.Parameters.AddWithValue("#Id", Id);
cmd.Connection = conn;
conn.Open();
IsDeleted = cmd.ExecuteNonQuery() > 0;
conn.Close();
}
}
if (IsDeleted)
{
ScriptManager.RegisterStartupScript(this, this.GetType(), "alert", "alert('Page Succesfully deleted');window.location ='csrposts.aspx';", true);
grdPostData.DataBind();
}
else
{
Response.Write("Some error");
}
}
Please let me know where I am going wrong. I tried debugging the code and the Id was taking 0.
Gridview bindinf Code:-
public void BindGrid()
{
string strQuery = "Select Id, title, description, Active from tbl_Post Order by ID desc";
SqlCommand cmd = new SqlCommand(strQuery);
DataTable dt = GetData(cmd);
grdPostData.DataSource = dt;
grdPostData.DataBind();
}
private DataTable GetData(SqlCommand cmd)
{
DataTable dt = new DataTable();
SqlConnection conn = new SqlConnection(System.Configuration.ConfigurationManager.ConnectionStrings["DefaultCSRConnection"].ConnectionString);
SqlDataAdapter sda = new SqlDataAdapter();
cmd.CommandType = CommandType.Text;
cmd.Connection = conn;
try
{
conn.Open();
sda.SelectCommand = cmd;
sda.Fill(dt);
return dt;
}
catch (Exception ex)
{
throw ex;
}
finally
{
conn.Close();
sda.Dispose();
conn.Dispose();
}
}

Updated Solution. Completely Working. I am Creating those textboxes in DataBound and theirs a if condition that checks whether Gridview is Empty or Not.
If Gridview is empty then HeaderRow wont be created so that Gridview and Page is able to display else HeaderRow will be Displayed.
Hope this Works for You.

Row Deleting Code is Same.

Your code looks good. Hope its not a problem from database. Try this
Add this to Gridview
OnRowCommand="GridView_RowCommand"
CodeBehing:-
protected void GridView_RowCommand(object sender, GridViewCommandEventArgs e)
{
if(e.CommandName=="Delete")
{
// Get the value of command argument
int Id= convert.ToInt32(e.CommandArgument);
// Do whatever operation you want.
}
}
Alternatively:-
Add onclick event on your imagebutton of delete and try this
protected void ImageButton_Click(object sender, EventArgs e)
{
ImageButton btn = sender as ImageButton;
GridViewRow gRow = (GridViewRow)btn.NamingContainer;
int id =Convert.ToInt32((gRow.FindControl("lblId") as Label).Text);
}
Update:-
Change your itemtemplate to this
<asp:TemplateField HeaderText="Post Category" ItemStyle-Width="50">
<ItemTemplate>
<asp:DropDownList ID="ddlPostCategory" AppendDataBoundItems="true" runat="server"
AutoPostBack="false">
<%-- <asp:ListItem Text="Select" Value="0"></asp:ListItem>--%>
</asp:DropDownList>
<asp:Label ID="lblId" runat="server" Text='<%# Eval("Id") %>' </asp:Label>
</ItemTemplate>
</asp:TemplateField>
So Fetched Id will be visible next to dropdownlist. Make sure its displaying correct value

asp.net gridview Sorting by date

I am sorting my date with my sql query and I get a proper result.
But as I apply
gridview.UseAccessibleHeader = true;
gridview.HeaderRow.TableSection = TableRowSection.TableHeader;
to my gridview. The sorted data gets unsorted.

this.gridviewname.MasterTemplate.EnableSorting = true;
this.RadGridView1.MasterTemplate.EnableSorting = True
SortDescriptor descriptor = new SortDescriptor();
descriptor.PropertyName = "Yourcolumnname";
descriptor.Direction = ListSortDirection.Ascending;
this.gridviewname.MasterTemplate.SortDescriptors.Add(descriptor);
descriptorcolumnname As New SortDescriptor()
descriptorShipName.PropertyName = "columnname"
descriptorShipName.Direction = ListSortDirection.Ascending
try this

Try this code which is working fine for me.

Approve / reject through dropdownlist

Previously I tried to approve / reject through button and try to code it..
This is code when I add buttons of approve / reject
protected void GrdFileApprove_RowCommand(object sender, GridViewCommandEventArgs e)
{
if (e.CommandName == "_Approve")
{
//using (SqlConnection con = DataAccess.GetConnected())
using (SqlConnection con = new
SqlConnection(ConfigurationManager.ConnectionStrings
["mydms"].ConnectionString))
{
try
{
con.Open();
int rowindex = Convert.ToInt32(e.CommandArgument);
GridViewRow row = (GridViewRow)
((Control)e.CommandSource).NamingContainer;
Button Prove_Button = (Button)row.FindControl("BtnApprove");
SqlCommand cmd = new SqlCommand("approveee", con);
//cmd.CommandType = CommandType.StoredProcedure;
cmd.CommandType = CommandType.StoredProcedure;
//con.Execute("approve", new { UserID, DocID, ApproveID });
cmd.Parameters.Add(new SqlParameter("#UserID", UserID));
cmd.Parameters.Add(new SqlParameter("#DocID", DocID));
cmd.Parameters.Add(new SqlParameter("#ApproveID", ApproveID));
int result = cmd.ExecuteNonQuery();
if (result != 0)
{
GrdFileApprove.DataBind();
}
}
catch
{
apfi.Text = "Not Approve";
}
finally
{
con.Close();
}
}
}
else if (e.CommandName == "_Reject")
{
using (SqlConnection con = new
SqlConnection(ConfigurationManager.ConnectionStrings
["mydms"].ConnectionString))
{
try
{
con.Open();
int rowindex = Convert.ToInt32(e.CommandArgument);
GridViewRow row = (GridViewRow)
((Control)e.CommandSource).NamingContainer;
LinkButton Prove_Button = (LinkButton)row.FindControl("Button1");
SqlCommand cmd = new SqlCommand("sprejectapprove", con);
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.Add(new SqlParameter("#UserID",UserID));
cmd.Parameters.Add(new SqlParameter("#DocID", DocID));
cmd.Parameters.Add(new SqlParameter("#ApproveID", ApproveID));
int result = cmd.ExecuteNonQuery();
if (result != 0)
{
GrdFileApprove.DataBind();
}
}
catch
{
apfi.Text = "Rejct";
}
finally
{
con.Close();
}
}
}
}
and this grdiview when I add dropdown..
<asp:GridView ID="GrdFileApprove" runat="server" BackColor="White"

<HeaderStyle BackColor="#336666" Font-Bold="True" ForeColor="White" />
</asp:GridView>
Now I want to code of dropdown.. when I click on approve/reject it can be approve/reject
how to code it and how to approve or reject through dropdown..

I have changed markup for DropDownList4:
<asp:DropDownList ID="DropDownList4" runat="server" class="vpb_dropdown" AutoPostBack="true" OnSelectedIndexChanged="DropDownList4_SelectedIndexChanged">
<asp:ListItem Text="Approve" Value="Approve"></asp:ListItem>
<asp:ListItem Text="Reject" Value="Reject"></asp:ListItem>
</asp:DropDownList>
And in the code:
protected void DropDownList4_SelectedIndexChanged(object sender, EventArgs e)
{
DropDownList ddl = sender as DropDownList;
if (ddl.SelectedValue == "Approved")
{
//Code to approve
}
else if (ddl.SelectedValue == "Reject")
{
//Code to reject
}
}

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));
}
DataRow row = table.NewRow();
row["Part"] = part;
row["Quantity"] = qty;
row["Ship-To"] = shipto;
row["Requested Date"] = reqdate;
row["Shipping Method"] = shipmthd;
table.Rows.Add(row);
Session["table"] = table;
griditems.DataSource = table.DefaultView;
griditems.DataBind();
}

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();
