using (SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString))

con.Open();

DataTable dt = new DataTable("dt");
cmd.Fill(dt);

I clicked only 1 check box value but it is blocking the whole column.help me out from the problem
If I'm understanding the question correctly, the problem is that all five checkboxes in the row are checked, regardless of what the value of hour is. This is because you are using
Checked='<%#Convert.ToBoolean((int)Eval("hour"))%>'
to set the value of the checkbox. You are converting the integer value of hour to a boolean value. Convert.ToBoolean will translate any non-zero integer to true, so as long as hour isn't zero, the checkbox will be checked.
Working example:
Creating datasource in code-behind:
DataTable dt = new DataTable("dt");
dt.Columns.Add("datee", typeof(string));
dt.Columns.Add("hour", typeof(int));
dt.Rows.Add("06-Jul-15 12:00:00 AM",1);
dt.Rows.Add("07-Jul-15 12:00:00 AM",2);
dt.Rows.Add("08-Jul-15 12:00:00 AM",3);
dt.Rows.Add("09-Jul-15 12:00:00 AM",4);
dt.Rows.Add("10-Jul-15 12:00:00 AM",5);
GridView1.DataSource = dt;
GridView1.DataBind();

I am currently developing an online shopping cart project.
I would like the program to display the GetTotal() in a label outside of the GridView.

All values in the GridView are passed on via session from another page, excluding Price and TotalUnitPrice, where calculations are carried out in the script below:
<script runat="server">
decimal TotalUnitPrice;
decimal GetUnitPrice(decimal Price)
{
TotalUnitPrice += Price;
return Price;
}
decimal GetTotal()
{
return TotalUnitPrice;
}
</script>
Any ideas on how to do this? The reason is that I would like the program to obtain the value of GetTotal()via the label and charge the user based on it.
Your GetTotal() in binding in GridView footer Label 16 so you can get it from there and set to outside Label:
// check if GridView is not empty
if (GridView1.Rows.Count != 0)
{
string total = ((Label)GridView1.FooterRow.FindControl("16")).Text;
LabelOutside.Text = total;
}

There is a button below the grid. on click of the button I need to get the values.
protected void LinkButton1_Click(object sender, EventArgs e)
{
foreach (GridViewRow item in GdvTestData.Rows)
{
CheckBox chk = (item.FindControl("CheckBox3") as CheckBox);
if (chk.Checked)
{
string conn = item.Cells[1].Text;
}
}
}
But am getting null value for string conn = item.Cells[1].Text;
where am I going wrong
Grid contains the different row type like header row , data row and footer row. You need to get content from the data row only then please check the row type first if it is a data row then try to get cell values. GridViewRow.RowType Property
foreach(GridViewRow item in GdvTestData.Rows) {
// check row is datarow
if (item.RowType == DataControlRowType.DataRow) {
CheckBox chk = (item.FindControl("CheckBox3") as CheckBox);
if (chk.Checked)
{
Label MyLabel = (Label)item.FindControl("lbl_conn");
string conn = MyLabel.Text;
}
}
}
all my commands are working properly but the problem is
after I execute my Search command then I click the select link button on my GridView, My Gridview is refreshing and select the first row in the grid view and not the one that I searched.. example: first I run the Index Page then the GridView get all the record from database(10 populated record) and show to the index.. (No Problem)
then I type the firstname of the user to search it then i click the search button then the it filtered and show to gridview again here's the image
then I click the "Select" link button from Gridview and this what happened
that's what happened .. I clicked the select link button on "marcy's record" then it refreshed and get the value of RASI's Record on the first row...
but when my click select without searching it worked just fine
here's my code for search button
string strconn;
strconn = "select * from User_TBL_DB where (Firstname like '%'+#search+'%' and Middlename like '%'+#search2+'%' and Lastname like '%'+#search3+'%')";
SqlCommand xp = new SqlCommand(strconn, conn);
xp.Parameters.Add("#search", SqlDbType.NVarChar).Value = firstname_search.Text;
xp.Parameters.Add("#search2", SqlDbType.NVarChar).Value = middlename_search.Text;
xp.Parameters.Add("#search3", SqlDbType.NVarChar).Value = lastname_search.Text;
conn.Open();
xp.ExecuteNonQuery();
SqlDataAdapter da = new SqlDataAdapter();
da.SelectCommand = xp;
DataSet ds = new DataSet();
da.Fill(ds, "Name");
GridView1.DataSource = ds;
GridView1.DataBind();
conn.Close();
and here's my code for select link button on gridview
row = GridView1.SelectedRow;
firstname_tb.Text = (row.FindControl("lbl_Firstname") as Label).Text;
middlename_tb.Text = (row.FindControl("lbl_Middlename") as Label).Text;
lastname_tb.Text = (row.FindControl("lbl_Lastname") as Label).Text;
age_tb.Text = (row.FindControl("lbl_Age") as Label).Text;
id_tb.Text = (row.FindControl("lbl_ID") as Label).Text;
string gender = (row.FindControl("lbl_Sex") as Label).Text;
if (gender == "FEMALE")
{
female_rb.Checked = true;
male_rb.Checked = false;
}
else
{
male_rb.Checked = true;
female_rb.Checked = false;
}

I am fill it using datatable on edit call this method
protected void GridView1_RowEditing(object sender,GridViewEditEventArgs e)
{
GridView1.EditIndex = e.NewEditIndex;
BindData();
}
and on update call update method
protected void GridView1_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
//Retrieve the table from the session object.
DataTable dt = (DataTable)Session["All_Topics"];
GridViewRow row = (GridViewRow)GridView1.Rows[e.RowIndex];

d1 = (TextBox)row.FindControl("TextBox1");
d2 = (TextBox)row.FindControl("TextBox2");

dt.Rows[row.DataItemIndex]["Sunday"] = d2.Text;
dt.Rows[row.DataItemIndex]["Monday"] = d3.Text;
dt.Rows[row.DataItemIndex]["Tuesday"] = d4.Text;
dt.Rows[row.DataItemIndex]["Wednesday"] = d5.Text;
}
the problem is when read data from the textbox it is always null. How can I solve this problem.
Hey please Make sure that do not re-binding the GridView on the PostBack of the page. This may be the cause of problem.
Always bind your grid on page load in side the below code.
if (!Page.IsPostBack ){
// Code to bind the Grid
// BindData();
}
when you are click on Row Update Command it is firstly go to the page load event and on page load if you are not binding your grid like the given manner your grid is rebind and you will get null from text box.
Hope it will helps you.
When the user changes the text in the textbox's in the edit template and clicks update, when I try to grab those new values it still is graving the old value of the text box.

The response is showing me that the value being grabbed is still the origonal text value of the box. Not what you typed into the box.
In your grid view row updating event add the following condition
protected void GridView1_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
if (e.Row.RowState == DataControlRowState.Edit )
{
int key = Convert.ToInt32(GridView1.DataKeys[e.RowIndex].Value);
Label CompanyID = (Label)GridView1.Rows[e.RowIndex].FindControl("txtCompanyID");
TextBox thisIssueDate = (TextBox)(GridView1.Rows[e.RowIndex].FindControl("txtIssueDate"));
TextBox NoticeIntentResponseDue = (TextBox)GridView1.Rows[e.RowIndex].FindControl("txtNoticeIntentResponseDue");
Response.Write(NoticeIntentResponseDue.Text + " " + thisIssueDate.Text);
Response.End();
TextBox DeadlineForQuestions = (TextBox)GridView1.Rows[e.RowIndex].FindControl("txtDeadlineForQuestions");
TextBox BidsDue = (TextBox)GridView1.Rows[e.RowIndex].FindControl("txtBidsDue");
TextBox ShortlistNotice = (TextBox)GridView1.Rows[e.RowIndex].FindControl("txtShortlistNotice");
TextBox FinalSelection = (TextBox)GridView1.Rows[e.RowIndex].FindControl("txtFinalSelection");
}
}
Update:
the problem looks like that you have also bind your Edit Item template columns with the data from data table, and when you are getting the data in the code behind you are not getting the updated data which the user updates in edit mode and u still getting the old data. If you remove the Binding from the Edit Item Template feilds then your code will work.
I figured it out, Derek was right. It had to do with the Binding Data on postback in page load. I binded the data every time instead of just the first time. Thanks
