what is the command of select in grid view asp.net

I have a GridView called gridview1
What I want is that if the user select or click on specific row some action will happen.
For example I want to get the value from that row and store it in a new variable.
How can I do it? I'm confused about what I should do to get the value?
protected void GridView1_SelectedIndexChanging(object sender, GridViewSelectEventArgs e)
{
string stuId = ?
}

<asp:GridView ID="GridView1" runat="server" HeaderStyle-BackColor="#3AC0F2" HeaderStyle-ForeColor="White"
AutoGenerateColumns="false" OnSelectedIndexChanged = "OnSelectedIndexChanged">
<Columns>
<asp:BoundField DataField="Name" HeaderText="Name" ItemStyle-Width="150" />
<asp:TemplateField HeaderText="Country" ItemStyle-Width="150">
<ItemTemplate>
<asp:Label ID="lblCountry" runat="server" Text='<%# Eval("Country") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:ButtonField Text="Select" CommandName="Select" ItemStyle-Width="150" />
</Columns>
</asp:GridView>
<br />
<u>Selected Row Values: </u>
<br />
<br />
<asp:Label ID="lblValues" runat="server" Text=""></asp:Label>
aspx.cs code
protected void Page_Load(object sender, EventArgs e)
{
if (!this.IsPostBack)
{
DataTable dt = new DataTable();
dt.Columns.AddRange(new DataColumn[3] { new DataColumn("Id"), new DataColumn("Name"), new DataColumn("Country") });
dt.Rows.Add(1, "John Hammond", "United States");
dt.Rows.Add(2, "Mudassar Khan", "India");
dt.Rows.Add(3, "Suzanne Mathews", "France");
dt.Rows.Add(4, "Robert Schidner", "Russia");
GridView1.DataSource = dt;
GridView1.DataBind();
}
}
protected void OnSelectedIndexChanged(object sender, EventArgs e)
{
//Accessing BoundField Column
string name = GridView1.SelectedRow.Cells[0].Text;
//Accessing TemplateField Column controls
string country = (GridView1.SelectedRow.FindControl("lblCountry") as Label).Text;
lblValues.Text = "<b>Name:</b> " + name + " <b>Country:</b> " + country;
}
you simply copy and paste your issue is resolve.

you could use like this:
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns = "false"
OnRowCommand = "OnRowCommand">
<Columns>
<asp:ButtonField CommandName = "ButtonField" DataTextField = "StudID"
ButtonType = "Button"/>
</Columns>
</asp:GridView>
protected void OnRowCommand(object sender, GridViewCommandEventArgs e)
{
int index = Convert.ToInt32(e.CommandArgument);
GridViewRow gvRow = GridView1.Rows[index];
}

Gridview Paging is not working when i use it in content place holder?

I dont know why paging is not working when i use master page. If I put the same code in another file which in not linked with master page it works like a charm. But when I link it to master page it doesn't work.

Please help me out. Any help would be highly appreciated.

Have you tried to create an empty master page to put the content into? I suspect your master page is breaking the GridView.

Problem Solved.
Actually button name was conflicting in grid view.
I was having a button and its ID was 'submit' and in my another page there was also a button named with the same ID. thats why gridview paging was not working.
R.I.P Coding.. :)

Gridview datasource is null after postback

I have a page with a gridview that show article groups,and textbox and search button for search groups.
in this page if user not search anything ,grid view only show main groups(with parentId 0)
and else show every group that group name's contain textbox value.
My problem is when I search ,and then I want to update some row,GridView1_RowUpdating not fired...
I found that the problem is that gridview datasource not bound successfully.
how I fix this problem?

when I try to update ,I get this error:
Index was out of range. Must be non-negative and less than the size of the collection.

Edit 2
Now I found that my problem is that gridview loses datasource on post back ,
I search but I not found solution.I don't want to use session or viewstate,because I have a lot of tables like above ,What is the solution?

set following property:
set AutoGenerateEditButton="False"
Try putting:
<asp:TemplateField>
<ItemTemplate>
<asp:Button id="btnEdit" runat="server" commandname="Edit" text="Edit" />
<asp:Button id="btnDelete" runat="server" commandname="Delete" text="Delete" />
</ItemTemplate>
<EditItemTemplate>
<asp:Button id="btnUpdate" runat="server" commandname="Update" text="Update" />
<asp:Button id="btnCancel" runat="server" commandname="Cancel" text="Cancel" />
</EditItemTemplate>
</asp:TemplateField>
In place of :
<asp:CommandField CausesValidation="false" ButtonType="Image" EditImageUrl="~/Icon/silk/application_edit.gif"
ShowEditButton="True" CancelImageUrl="~/Icon/silk/arrow_undo.gif" UpdateImageUrl="~/Icon/silk/accept.gif"

GridView Delete Row

I'm trying to delete a row in a gridview (the data is not in the database yet), so it should be a simple delete row, if anybody can please point me in the right direction....
This is what I have done:
else if (e.CommandName == "DeletePart")
{
int index = Convert.ToInt32(e.CommandArgument); //#1 line
GridView1.DeleteRow(index); //#2 line
}
The error that I am receiving is : "Input string was not in a correct format." (this happens on #1 line)...
This is how the gridview looks like: (use a linkbutton to do the delete)
<asp:GridView ID="GridView1" runat="server" AllowPaging="True"
EmptyDataText="No parts has been added to the model, please add a part."
BorderColor="Black" BorderStyle="Solid" BorderWidth="2px"
CellPadding="3" onrowcommand="GridView1_RowCommand"
onrowediting="GridView1_RowEditing" onrowdeleting="GridView1_RowDeleting">
<Columns>
<asp:TemplateField HeaderText="">
<ItemTemplate>
<asp:LinkButton ID="EditButton" runat="server" CssClass="EditButton" CommandName="Edit" Text="Edit" />
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="">
<ItemTemplate>
<asp:LinkButton ID="DeleteButton" runat="server" CssClass="DeleteButton" CommandName="DeletePart" CommandArgument='<%# Container.DataItemIndex %>' Text="Delete" />
</ItemTemplate>
</asp:TemplateField>
</Columns>
<HeaderStyle BackColor="#FFFFCC" BorderColor="Black" BorderStyle="Solid"
BorderWidth="2px" />
</asp:GridView>
Class of how the gridview populated and binded:
public int companyID = 0;
public int methodID = 0;
DataTable dt;
#region SQLConnections
string connectionString = ConfigurationManager.ConnectionStrings["SOSConnectionString"].ConnectionString;
SqlConnection conn;
#endregion
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{

}
else
{
dt = (DataTable)ViewState["DataTable"];
}
ViewState["DataTable"] = dt;
}
#region GridView
private void EmptyDataString()
{
TemplateBuilder tmpEmptyDataTemplate = new TemplateBuilder();
tmpEmptyDataTemplate.AppendLiteralString("No parts has been added to the model, please add a part.");
GridView1.EmptyDataTemplate = tmpEmptyDataTemplate;
GridView1.DataBind();
}
private void MakeDataTable()
{
dt.Columns.Add("Item");
dt.Columns.Add("Quantity");
dt.Columns.Add("Price P/Quantity");
}
private void AddToDataTable()
{
DataRow dr = dt.NewRow();
dr["Item"] = txtPart.Text;
dr["Quantity"] = numQuantity.Text;
dr["Price P/Quantity"] = txtPricePQ.Text;
dt.Rows.Add(dr);
}
private void BindGrid()
{
GridView1.DataSource = dt;
GridView1.DataBind();
}
protected void btnAddPart_Click(object sender, EventArgs e)
{
AddToDataTable();
BindGrid();
ClearNewParts();
}
#endregion
protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
{
if (e.CommandName == "Edit")
{
for (int i = 0; i < GridView1.Rows.Count; i++)
{
GridViewRow row = (GridViewRow)(((LinkButton)e.CommandSource).NamingContainer);
txtPart.Text = row.Cells[2].Text;
numQuantity.Text = row.Cells[3].Text;
txtPricePQ.Text = row.Cells[4].Text;
}
}
else if (e.CommandName == "DeletePart")
{
//int iCount = GridView1.Rows.Count;
//for (int i = 1; i <= iCount; i++)
//{
// GridView1.DeleteRow(i);
//}
// int rowIndex = Convert.ToInt32(GridView1.SelectedRow);
int index = Convert.ToInt32(e.CommandArgument);
GridView1.DeleteRow(index);
//int index = Convert.ToInt32(e.CommandArgument);
//GridView1.DeleteRow(rowIndex);
}
GridView1.DataBind();
}

Found the solution, only needed to do a databound.... Here is the working code:
else if (e.CommandName == "Delete")
{
int index = Convert.ToInt32(e.CommandArgument);
GridView1.DeleteRow(index);
((DataTable)ViewState["DataTable"]).Rows[index].Delete();
((DataTable)ViewState["DataTable"]).AcceptChanges();
GridView1.DataSource = (DataTable)ViewState["Data"];
GridView1.DataBind();
}

Seems like you didn't mention CommandArgument property in the GridView.
<asp:GridView runat="server" ID="gv"
CommandName="DeletePart"
CommandArgument='<%# Container.DataItemIndex %>'>
</asp:GridView>
Add the CommandArgument as shown above.

Try this..
In ASPX:
<asp:GridView runat="server" ID="Gridview1" CommandName="delete" CommandArgument='<%#Container.DataItem.Index %>'/>
Cs:
else if (e.CommandName == "DeletePart")
{
int index = Convert.ToInt32(e.CommandArgument);
GridView1.DeleteRow(index);
}

try int.TryParse , this will solve the input string fromat problem , but why is it occuring that you need to check the CommandArgument you are setting.
else if (e.CommandName == "DeletePart")
{
int index =-1;
if(int.TryParse(e.CommandArgument,out index)) //#1 line
GridView1.DeleteRow(index); //#2 line
}

Thy This:)
<asp:GridView ID="GridView1" runat="server" CssClass="gridview"
HorizontalAlign="Left" PagerSettings-Visible="true" AllowPaging="True"
PageSize ="5" Width="300px" >
<Columns>
<asp:CommandField ShowDeleteButton="True" ButtonType="Button" />
</Columns>
</asp:GridView>
then code behinde:
Protected Sub GridView1_RowDeleting(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewDeleteEventArgs) Handles GridView1.RowDeleting
DirectCast(ViewState("CurrentDataReference"), DataTable).Rows.RemoveAt(e.RowIndex)
GridView1.DataSource = DirectCast(ViewState("CurrentDataReference"), DataTable)
GridView1.DataBind()
End Sub

Gridview in Modal Popup Extender- Postback Issues?

I have a C# .Net application with a gridview within an Ajax Modal Popup (VS2008). I have the grid view set to return 10 records per page with paging enabled.
When the user clicks to change page within the gridview there is a postback which closes the modal window and then opens it again using ModalPopup.show();
Is there any way to avoid the postback of the whole page and just postback the gridview whilst keeping the modal window active? At the moment the postback of the whole page gives the impression of flicker...

thanks for your suggestion. I've put the gridview into a...
<asp:UpdatePanel>
<ContentTemplate>
The modal now stays however when I click a record in the grid view it doesn't close!
