How can i hold gridview row selected values into a string in asp.net

I have gridview control it contains 6 columns when i click 6th column row of gridview i need to selecte that contains columns row text into a string. how can i take here i am taking commandargument is a string and how can i take another column names text
my code:
<asp:GridView ID="GridView1" Width="950px" CssClass="Grid" runat="server" AutoGenerateColumns="false" OnRowCommand="GridView1_RowCommand" >
<Columns>
<asp:GridView ID="GridView1" Width="950px" CssClass="Grid" runat="server" AutoGenerateColumns="false" >
<Columns>
<asp:BoundField DataField="ID" HeaderText="" ItemStyle-ForeColor="White" />
<asp:BoundField DataField="Name" HeaderText="Name" />
<asp:BoundField DataField="SName" HeaderText="SName" />
<asp:BoundField DataField="Date" HeaderText="Date" />
<asp:BoundField DataField="Size" HeaderText="Size(MB)" />
<asp:BoundField DataField="Time" HeaderText="Time" />
<asp:TemplateField HeaderText="FileName">
<ItemTemplate>
<asp:LinkButton ID="lnkDownload" runat="server" CausesValidation="False" CommandArgument='<%# Eval("FileName") %>'
CommandName="Download" Text='<%# Eval("FileName") %>' />
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="S.No." Visible="false">
<ItemTemplate>
<asp:Label ID="lblID" runat="server" Text='<%#Bind("ID") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
{
string ID1;
if (e.CommandName == "Download")
{
GridViewRow gvr = (GridViewRow)((Control)e.CommandSource).NamingContainer;
int rowIndex = gvr.RowIndex;
Label Itemid = (Label)GridView1.Rows[rowIndex].FindControl("lblID");
ID1 = (Itemid).Text;
Session["ID"] = ID1;
string filename = e.CommandArgument.ToString();
//here how can i hold another column text
}
}

I have a easiest way to do this same thing...
<asp:Label ID="lblName" runat="server" Text='<%#Eval("ID").ToString() +", "+ Eval("OtherCoulmn").ToString() %>'></asp:Label>
--- hope it helps
Also the best way is to do something like this
((MyObject)Container.DataItem).MyProperty where MyObject is the Model which you bind with grid and property which you wan to use in rowcommand its clean .

Simply follow the bellow code sample:
protected void btnEdit_Click(object sender, EventArgs e)
{
Button btn = sender as Button;
GridViewRow gvr = (GridViewRow)btn.NamingContainer;
Label lblId = gvCipamMember.Rows[gvr.RowIndex].FindControl("lblPersonId") as Label;
cmd = new SqlCommand("SELECT Id,Res_Person,Email_ID,Mobile_NO,Cipam_Flag FROM Responsibilty_Master WHERE Id=#Id", con.MyConnection);
cmd.Parameters.AddWithValue("#Id", Convert.ToInt32(lblId.Text.ToString()));
dt = new DataTable();
con.MyConnection.Open();
dt.Load(cmd.ExecuteReader());
if (dt.Rows.Count > 0)
{
txtPersonName.Text = dt.Rows[0]["Res_Person"].ToString();
txtEmail.Text = dt.Rows[0]["Email_ID"].ToString();
txtMobileNo.Text = dt.Rows[0]["Mobile_NO"].ToString();
if(Convert.ToBoolean(dt.Rows[0]["Cipam_Flag"].ToString())==true)
{
chkbCipamFlag.Checked = true;
}
}
}

finding label in itemTemplate and bind data from code behind

I wanted to display value in a label (label inside itemTemplate)
i have tried this approach
string s = null;
SelfCollectNameSpace.SelfCollect address = new SelfCollectNameSpace.SelfCollect();
s = address.getSelfCollectAddress(orderNoTracking);
if (string.IsNullOrEmpty(s) == false)
{
foreach (GridViewRow row in GridView1.Rows)
{
string LabelText = ((Label)row.FindControl("labelSelf")).Text;
LabelText = s;
Response.Write(LabelText+"test");
}
}
but nothing is shown in the label inside the gridview. IT should display the value of s.
Next approach was
string s = null;
SelfCollectNameSpace.SelfCollect address = new SelfCollectNameSpace.SelfCollect();
s = address.getSelfCollectAddress(orderNoTracking);
Label labelSelfCollect = GridView1.FindControl("labelSelf") as Label;
labelSelfCollect.Text = "Self Collect at "+ s;
I got this error
System.NullReferenceException: Object reference not set to an instance of an object.
and the last approach that i have used is
string s = null;
SelfCollectNameSpace.SelfCollect address = new SelfCollectNameSpace.SelfCollect();
s = address.getSelfCollectAddress(orderNoTracking);
if (string.IsNullOrEmpty(s) == false)
{
foreach (GridViewRow row in GridView1.Rows)
{
if (row.RowType == DataControlRowType.DataRow)
{
Label labelcollect = row.FindControl("labelSelf") as Label;
labelcollect.Text = "self collect at "+ s;
}
}
}
using this method also it shows nothing.How should i assign the s value into this labelSelf(label inside itemTemplate)?

Thank you.

Use GridView1_OnRowDataBound instead of foreach (GridViewRow row in GridView1.Rows). Apart from that your first approach is correct. You're simply not assigning the Text property there but reading from it.
SelfCollectNameSpace.SelfCollect address = new SelfCollectNameSpace.SelfCollect();
protected void MyGrid_RowDataBound(object sender, GridViewRowEventArgs e)
{
if(e.Row.RowType == DataControlRowType.DataRow)
{
Label labelSelf = (Label)e.Row.FindControl("labelSelf");
labelSelf.Text = address.getSelfCollectAddress(orderNoTracking); // maybe you need to retrieve the orderNoTracking from another control in this row or from it's datasource
}
}

Remove Hyperlink of specif cell in gridview

I've created a gridview, which all values (footer included) are hyperlinks, to export a detail in Excel.
All is working fine, except, when the value is 0, I don't want to permit the hyperlink, so it doesn't create a empty excel.
<asp:GridView ID="dtlist" runat="server" CellPadding="0" CssClass="table tabela caixa " CellSpacing="0" OnRowDataBound="dtlist_RowDataBound" AutoGenerateColumns="false" GridLines="Vertical" BorderStyle="Solid" ShowFooter="true" >
<Columns >
<asp:TemplateField HeaderText="Name">
<ItemTemplate>
<asp:Label ID="Label2" runat="server" Text='<%# Eval("name") %>'></asp:Label>
</ItemTemplate>
<FooterTemplate>
<asp:Label ID="LabelT" runat="server" Text="Total"></asp:Label>
</FooterTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Value">
<ItemTemplate>
<asp:HyperLink runat="server" ID="lnkA" NavigateUrl='<%# String.Format("/Export?name={0}, Eval("name")) %>' Text='<%# Eval("value","{0:#####,##0.00 €}") %>' />
<asp:Label runat="server" ID="lblA" Text='<%# Eval("value","{0:#####,##0.00 €}") %>' Visible="false" />
</ItemTemplate>
<ItemStyle CssClass="alinha-direita" />
<FooterTemplate>
<asp:HyperLink runat="server" ID="lnkTA" />
</FooterTemplate>
<FooterStyle CssClass="alinha-direita" />
<HeaderStyle CssClass="alinha-meio" />
</asp:TemplateField>
</Columns>
</asp:GridView>
This is the RowDataBound:
protected void dtlist_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.Header)
{
Total = 0;
}
if (e.Row.RowType == DataControlRowType.DataRow)
{
HyperLink hA = (HyperLink)e.Row.FindControl("lnkA");
Label lA = (Label)e.Row.FindControl("lblA");
if (hA.Text.ToDecimal() == 0)
{
hA.Visible = false;
lA.Visible = true;
}
Total += ((DataRowView)e.Row.DataItem).Row["Ano0"].ToDecimal();
}
if (e.Row.RowType == DataControlRowType.Footer)
{
HyperLink tA = (HyperLink)e.Row.FindControl("lnkTA");
tA.NavigateUrl = String.Format("/ExportStock?name={0}","ZZZZ");
tA.Text = Total0.StringEuro();
}
}
I've tried to ask on the e.Row.RowType == DataControlRowType.DataRow, if the value of the Hyperlink is 0, but if one value on the column is 0 it disables all hyperlinks on that column.
How can I remove only for the 0 cell?
Thanks.

How to specify which control to use in the gridview rowupdate

I have a gridview and several template fields and several rowcommands. I would like to use the built in update row command but the problem I'm running into is making it so my application isn't functioning correctly.
Problem: In one of my edititem template fields I have both a Label control and a dropdown control. The reason for this is that I need to hide/show one or the other depending on the rowcommand is triggered. When I use the built in edit rowcommand I hide the dropdown and display the dropdownlist. So everything works there. However, when update rowcommand is triggered it is using the label value which is not visible and is bound to display the month rather than the full date that is needed. I use the drop down list to display the month to the user and the selected value is the full date. For some odd reason it wants to use the label value instead of the drop down list selected value even though I specify the update parameter in the code behind. If I remove the label from the commissionmonth column then everything works just fine except for the fact that on my other row commands the drop down list I would have to display a drop down list instead of the wanted label.
If any of you know how to specify the control to use in the update rowcommand or somehow dynamically change that column to read only on certain row commands I would greatly appreciate it!

Trying to Add Insert Row to Footer in GridView ASP.net

I'm trying to give the user the ability to create a new record from the footer row and my event handler doesn't seem to be working... or maybe I'm going at this all wrong.
The insert button that I enabled in the gridview doesn't work either...checkout the site at http://aisched.engr.oregonstate.edu/admin/courses.aspx
Here is my code in front and behind:
public partial class admin_courses : System.Web.UI.Page
{
public Table table;
ListDictionary listValues = new ListDictionary();
TextBox textBox1 = new TextBox(); //Name
TextBox textBox2 = new TextBox(); //CR
TextBox textBox3 = new TextBox(); //CourseNum
TextBox textBox4 = new TextBox(); //Dept
protected void Page_Init()
{
}
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType != DataControlRowType.Footer) return; //Escape if not footer
textBox1.ID = "name";
textBox1.Width = 250;
textBox2.ID = "credit_hours";
textBox2.Width = 25;
textBox3.ID = "dept";
textBox3.Width = 30;
textBox4.ID = "class";
textBox4.Width = 25;
LinkButton add = new LinkButton();
add.ID = "add";

I couldn't make it work without writing code manually to do the Insert. Handling the AddLinkButton_Click event in the Page_Load event by examining the EventTarget hidden field to see if it ends with 'addlinkbutton' feels quite wrong, but it works.

A Sample pseudo code which can add from grid view footer, Initially data's are saved under View State, Using button click event to check the ViewState and insert the new data to the table.
