Gridview linkbutton postbackurl change on page load event - c#

I have a gridview with a linkbutton, the url linkbutton is assigned using a code by replacing a key word with a name from the DB.
all works fine, except that when I click the back button in browser and try different link I get this error:
"The HTTP verb POST used to access path '/System.Web.UI.WebControls.Label' is not allowed"
below is my code:
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
Response.Cache.SetCacheability(HttpCacheability.NoCache);
GridView1.DataSourceID = "SqlDataSource1";
GridView1.DataBind();
foreach (GridViewRow row in GridView1.Rows)
{
if (row.RowType == DataControlRowType.DataRow)
{
var HyperLink = row.FindControl("LinkButton1") as LinkButton;
var RepID = row.FindControl("Label1") as Label;
if (RepID != null)
{
StringBuilder lnk = new StringBuilder("http://bhvwtwbis2/Ops/_layouts/ReportServer/RSViewerPage.aspx?rv:RelativeReportUrl=/Ops/GAPPBASE/Reports/kai.rdl&Source=http%3A%2F%2Fbhvwtwbis2%2FOps%2FGAPPBASE%2FForms%2FAllItems%2Easpx%3FRootFolder%3D%252FOps%252FGAPPBASE%252FReports%26FolderCTID%3D0x012000D833091DB062524DA7A0550847E4E075%26View%3D%7B8A039A42%2D111E%2D40C4%2D8489%2D0D7F32CEAF36%7D&DefaultItemOpen=1");
lnk.Replace("kai", RepID.Text + "x1");
HyperLink.PostBackUrl = lnk.ToString();
}

I think the problem might be that you're doing your binding at the Page_Load stage of the page life cycle. Try moving your foreach code to a
protected void gridview1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
var HyperLink = e.Row.FindControl("LinkButton1") as LinkButton;
//var RepID = row.FindControl("Label1") as Label;
//You should be able to access your field without referencing the label too
DataRow row = ((DataRowView)e.Row.DataItem).Row;
var myField = row.Field<string>("report_name");
if (RepID != null)
{
StringBuilder lnk = new StringBuilder("http://bhvwtwbis2/Ops/_layouts/ReportServer/RSViewerPage.aspx?rv:RelativeReportUrl=/Ops/GAPPBASE/Reports/kai.rdl&Source=http%3A%2F%2Fbhvwtwbis2%2FOps%2FGAPPBASE%2FForms%2FAllItems%2Easpx%3FRootFolder%3D%252FOps%252FGAPPBASE%252FReports%26FolderCTID%3D0x012000D833091DB062524DA7A0550847E4E075%26View%3D%7B8A039A42%2D111E%2D40C4%2D8489%2D0D7F32CEAF36%7D&DefaultItemOpen=1");
lnk.Replace("kai", myField + "x1");
HyperLink.PostBackUrl = lnk.ToString();
}
}
}

How can remove/replace substring from GridView Column?

I have below GridView:
I want to remove 0:00:00 from date column, if exists. I change dataformatstring but that remove 9:09:15 too.
I use auto-generate fields and DataBind on .cs file.
I tried Replace, but does not work:
e.Row.Cells[0].Text = e.Row.Cells[0].Text.Replace("0:00:00"," ");
How can I do that?
Gridview:
<asp:GridView ID="GridView4" runat="server" BackColor="White"

OleDbConnection Connection6;
using (Connection6 = new OleDbConnection("Provider=MSDAORA.1;Data Source=XXXXXX:1521/orcl;Persist Security Info=True;Password=XXXXXXX;User ID=XXXXXX;"))
{
string sqlQuery = "select * from db.user";
using (OleDbDataAdapter cmd = new OleDbDataAdapter(sqlQuery, Connection6))
{
Connection6.Open();
DataTable dt = new DataTable();
cmd.Fill(dt);
GridView4.DataSource = dt;
GridView4.DataBind();
Connection6.Close();
}
}
}
catch (Exception)

}
You can use RowDataBound event, then label control using findcontrol
<asp:GridView ID="GridView1" AutoGenerateColumns="false" runat="server"
onrowdatabound="GridView1_RowDataBound">
<Columns>
<asp:TemplateField HeaderText="Date">
<ItemTemplate>
<asp:Label ID="lblDate" Text='<%# Eval("Date") %>' runat="server"></asp:Label>
.....
</Columns>
</asp:GridView>
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
var lbl = e.Row.FindControl("lblDate") as Label;
lbl.Text = lbl.Text.Replace("0:00:00", "");
}
}
If you don't have Template Field and using Bound Field then Use
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
if(e.Row.Cells[0].Text.Contains("0:00:00"))
e.Row.Cells[0].Text = e.Row.Cells[0].Text.Replace("0:00:00", "");
}
}

GridView Order of Operations

No error as such, but the way I have it setup, the GridView renders on Page_Load, it would seem that then the rest of operations that I have setup don't seem to fire.
Any ideas on the order? Been at it for hours now :(

Dynamic link in asp.net gridview

I'm trying to create a gridview with an extra column that contains a hyperlink for each row. Unfortunately my hyperlinks doesn't start from the top of the column, instead they are started from the second row of the hyperlink's column.
See this picture for more information >>> http://i.imgur.com/TLsVo5s.png
As you can see in that picture, there is a 'view' column that contains hyperlinks, but the problem is the first row is always empty. The hyperlink that's on the second row should be on the first, and the third should be on the second, and so on.
Can anyone show me where I went wrong?
Here is my gridview declaration on my aspx page:
<asp:GridView ID="GridView1" runat="server" CellPadding="4" AllowPaging="True"
AllowSorting="True" AutoGenerateColumns="False"
OnPageIndexChanging="GridView1_PageIndexChanging"
OnSorting="GridView1_Sorting" PageSize="20" DataKeyNames="no_kwitansi"

<SortedAscendingHeaderStyle BackColor="#AF0101" />

<Columns>
<asp:BoundField HeaderText="#" />
<asp:BoundField DataField="no_kwitansi" HeaderText="No.Kwitansi" SortExpression="no_kwitansi" ReadOnly="True" />
<asp:BoundField DataField="nama_vendor" HeaderText="Vendor" SortExpression="nama_vendor" />
<asp:BoundField DataField="nama_pekerja" HeaderText="Pekerja" SortExpression="nama_pekerja" />
<asp:BoundField DataField="nama_penanggungjawab" HeaderText="Penanggungjawab" SortExpression="nama_penanggungjawab" />
<asp:BoundField DataField="satuan" HeaderText="Satuan" SortExpression="satuan" />
<asp:BoundField DataField="jumlah" HeaderText="Nominal" SortExpression="jumlah" />
<asp:BoundField DataField="tanggal" HeaderText="Tanggal" SortExpression="tanggal" />
</Columns>
</asp:GridView>
Here is my C# code behind:
This is my page_load function, I created the template field here.
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
ViewState["SortExpr"] = Sort_Direction;
TemplateField tfield = new TemplateField();
tfield.HeaderText = "View";
GridView1.Columns.Add(tfield);
home1.DataBind();
}
}
Here is my gridview rowDataBound function, where I create the hyperlink.
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
HyperLink hlContro = new HyperLink();
for (int i = 0; i < GridView1.Rows.Count; i++)
{
hlContro.NavigateUrl = "./Home.aspx?ID=" + GridView1.Rows[i].Cells[1].Text;
//hlContro.ImageUrl = "./sample.jpg";
hlContro.Text = "Documents";
//GridView1.Rows[i].Cells[0].Controls.Add(hlContro);
}
e.Row.Cells[8].Controls.Add(hlContro);
}
}
so why not just a template field, and remove all the server side boilerplate? What happen if you would change position of your column?
Below is the solution where you need not to write anything in your server side code. Simple and easy.
<asp:TemplateField HeaderText="Active">
<ItemTemplate>
<asp:HyperLink ID="HyperLink1" runat="server" Text='<%# Eval("no_kwitansi") %>'
NavigateUrl= '<%# "./Home.aspx?ID=" + Eval("no_kwitansi") %>'>
</asp:HyperLink>
</ItemTemplate>
</asp:TemplateField>
The RowDataBound event is raised when a data row (represented by a GridViewRow object) is bound to data in the GridView control. This enables you to provide an event-handling method that performs a custom routine, such as modifying the values of the data bound to the row, whenever this event occurs.
Just write code like this
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
HyperLink hlContro = new HyperLink();
hlContro.NavigateUrl = "./Home.aspx?ID=" + e.Row.Cells[1].Text;
//hlContro.ImageUrl = "./sample.jpg";
hlContro.Text = "Documents";
//GridView1.Rows[i].Cells[0].Controls.Add(hlContro);
e.Row.Cells[8].Controls.Add(hlContro);
}
}
why are you adding it from code behind even you can add in html page
<asp:TemplateField HeaderText="View">
<ItemTemplate>
<asp:LinkButton ID="test1" runat="server" ForeColor="#525252" Text="Documents" />
</ItemTemplate>
</asp:TemplateField>
a similar example is shown on this link you can try Link

Have you tried it by using the "OnRowDataBound" or "OnRowCreated" Event of the Grid and write the color-highliting in code behind?
Something like this?
http://www.java2s.com/Code/ASP/ADO.net-Database/UsingtheRowCreatedEventtoprogrammaticallychangethestyle.htm
But maybe you have a problem because the loading would be too fast to really notice?

reader = cmd.ExecuteReader();
ClientScript.RegisterStartupScript(this.GetType(), "conferma", "alert('Data Restituzione inserita!');window.location='Default.aspx';", true);
reader.Close();
conn.Close();
}
}
}
}
}
How i do to update the database when i set the date into my textbox?
The query string is not correct. Thanks!
Instead of the ExecuteReader() use ExecuteNonQuery(), that might do the trick.
GxG is right. ExecuteReader() is use to fetch the single record(Column) while to DML(Data Manipulation Language, like INSERT,DELETE,UPDATE) we use ExecuteNonQuery().
