<asp:GridView runat="server" ID="gridUserAccounts" SkinID="gridviewSkin" PageSize="5">
<Columns>
<asp:BoundField HeaderText="User Name" DataField="UserName" />
<asp:BoundField HeaderText="Email" SortExpression="Email" DataField="Email" />

</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
Code behind for this is
if (!Page.IsPostBack)
{
gridUserAccounts.DataSource = Membership.GetAllUsers();
gridUserAccounts.DataBind();
}
Now, at 'manage-user-detail.aspx' page i am catching the query string but it doen't work like this
if (!IsPostBack)
{
string userKey1 = Request.QueryString["UserName"];
Guid UserID = new Guid(Membership.GetUser(userKey1).ProviderUserKey.ToString());
//Guid userKey = new Guid(userKey1);
MembershipUser mu = Membership.GetUser(UserID);
//string userName = mu.UserName;
lblKey.Text = mu.UserName;
}
Nothing is showing up in label. Why?
I solve the problem with following code
string userName = Membership.GetUser(Request.QueryString["UserName"].ToString()).UserName;
statusLabel.Text = userName;
From my experience the only way to get the querystring is like so:
Request.QueryString.Item("UserName");
I see that in your code you left out Item.

I've done my research here and I can now succesfully get a value of a hidden boundfield column in my gridview. The problem is I can't target the a hidden column of the row that I selected.
can I use GridView1.SelectedRow.Cells[7].Text; something like that on a hidden column.Is it possible?
here is my code:
protected void GridView1_SelectedIndexChanged(object sender, EventArgs e)
{
//GridView1.Columns[7].Visible = true;
//stock_id_gridview_1();
foreach (GridViewRow row in GridView1.Rows)
{
string id = GridView1.DataKeys[row.RowIndex]["id"].ToString();
con.Open();
cmd = new SqlCommand(#"SELECT transaction_id,transaction_number
FROM stocks_history
WHERE id = #id", con);
cmd.Parameters.AddWithValue("#id", id);
rdr = cmd.ExecuteReader();
if (rdr.HasRows)
{
while (rdr.Read())
{
transaction_id = rdr["transaction_id"].ToString();
//lbl_test_id.Text = rdr["transaction_id"].ToString();
transaction_number = rdr["transaction_number"].ToString();
lbl_test_id.Text = transaction_id + " " + transaction_number;
}
}
con.Close();
}
here is my gridview:

If You use attribute DataKeyNames, you can take value from invisible column like
Use Attribute
<asp:GridView runat="server" ID="GridView" DataKeyNames="id">
</asp:GridView>
And you can access the data
var id = GridView.DataKeys[RowIndex].Values[KeyIndex]
To get selected row hidden column value
var id = GridView.DataKeys[GridView.SelectedRow.RowIndex].Values[0];
I want to access the HyperLinkField column of the GridView from code behind but I am unable to do so.
I have the column in my dataset but I am still not able to use it.
My HyperLinkField column is named Status.
Here is what I tried:
UltraWebGrid1.DataSource = ObjPriDsGrid;
UltraWebGrid1.DataBind();
string StrPriStatus = "";
for (int IntPriI = 0; IntPriI < UltraWebGrid1.Rows.Count; IntPriI++)
{
if (UltraWebGrid1.Rows[IntPriI].Cells[6].Text.Trim() != null)
{
StrPriStatus = UltraWebGrid1.Rows[IntPriI].Cells[6].Text.Trim();
}
else
{
}
if (StrPriStatus == "5")
{
UltraWebGrid1.Rows[IntPriI].Cells[8].Text = ""; // Not getting status column here
}
}
Here is my GridView:
<asp:GridView ID="UltraWebGrid1" ShowHeader="true" runat="server" AutoGenerateColumns="false"

Columns like HyperLinkField and CheckBoxField behave a little differently than BoundField. They don't just simply contain text like BoundField. You have to get the control within the cell. You can get the child controls of the cell using the Controls collection. We know that specifically for a HyperLinkField, the HyperLink will be the first control in the collection.
HyperLink hyp = (HyperLink)UltraWebGrid1.Rows[IntPriI].Cells[12].Controls[0];
Can you try it like this
if (StrPriStatus == "5")
{
HyperLink HyperLinkObj = (HyperLink)UltraWebGrid1.Rows[IntPriI].Cells[12].Controls[0];
HyperLinkObj.Text = "";
}
Hi i did look at search result for " DataTable must be set prior to using DataView." but none of their solutions fixed my problem or pointed me in the right direction.
Were am i going wrong here, when i press a header to sort out the gridview table i just get an error and no sorting. The error is the same as my title for this post.
EDIT: Not sure if its relevant but i populate the gridview on page load from a MS SQL database

Seems to me that the problem is within SortGridView method. You try to use the very same DTSorting property you attempt to set as the table constructor parameter. If it is null at this point it will most definitely throw an exception. DataView needs an existing DataTable instance to work with.
I should also mention that the current implementation will likely create multiple DataTable instances that won't ever get disposed of. One thing for sure is that you aren't disposing of the DataView object you are creating so that you get your sorted table.
If I were you I would rethink how data should be bound. Storing a DataTable object in ViewState is bad practice. The full table will be serialized back and forth between the client and the server, resulting in performance loss.
I suggest you read about it here: View State Overview
I am having trouble accessing an asp.NET HiddenField from a Gridview ItemTemplate in the codebehind. I need to be able to read the values that these hiddenfields contain so that I can execute the delete method.

HiddenField Email = GridView1.FindControl("HiddenEmail") as HiddenField;
string username = Username.Value;
string email = Email.Value;
AdminAccess.DeleteMemberApplication(username, email);
}
Any help would be greatly appreciated.
The HiddenField controls are going to be part of a <td> which is one of the <tr> the GridView renders. The GridView control's FindControl only knows of it's immediate children and as the Hidden controls are two levels below that, it's not going to find them. Instead, start from the sender and try to find its sibling Hidden controls. Replace the two HiddenControl lines in the event handler as below:
HiddenField Username = (HiddenField) ((Button)sender).Parent.Controls.FindControl("HiddenUsername");
HiddenField Email = (HiddenField) ((Button)sender).Parent.Controls.FindControl("HiddenEmail");
And it should get the values you are looking for to delete the data in that row.
Just use CommandArgument of button
<asp:TemplateField HeaderText="Edit" AccessibleHeaderText="Edit">
<ItemTemplate>
<asp:HyperLink ID="EditUsername" runat="server" NavigateUrl='<%# Link.ToMemberAdmin(Eval("Username").ToString())%>'

CommandArgument='<%#Eval("Username")+"^"+Eval("Email") %>'/>
</ItemTemplate>
</asp:TemplateField>
protected void DeleteButton_Click(object sender, EventArgs e)
{
var btn = sender as Button;
var args = btn.CommandArgument.Split('^');
string username = args[0];
string email = args[1];
AdminAccess.DeleteMemberApplication(username, email);
}

Try
GridViewRow gRow = (GridViewRow)(sender as Control).Parent.Parent;
string trying_to_get = string.Empty;
if (gRow != null)
{
trying_to_get = gRow.Cells[0].Text;
}
