i have a edit function in my gridview. however what i want to do is to disable the visibility of the textbox when i click on update function on a specific data bound. here is my aspx code:

and here is my update code behind:
protected void GridView1_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
//Finding the controls from Gridview for the row which is going to update
//Label id = GridView1.Rows[e.RowIndex].FindControl("lbl_ID") as Label;
int userid = Convert.ToInt32(GridView1.DataKeys[e.RowIndex].Value.ToString());
TextBox ProductName = GridView1.Rows[e.RowIndex].FindControl("txtboxProductName") as TextBox;
TextBox ProductDescription = GridView1.Rows[e.RowIndex].FindControl("txtboxProductDescription") as TextBox;
TextBox ProductQuantity = GridView1.Rows[e.RowIndex].FindControl("txtboxProductQuant") as TextBox;
TextBox ProductPrice = GridView1.Rows[e.RowIndex].FindControl("txtboxProductPrice") as TextBox;
conn = new SqlConnection("Data Source = 'PAULO'; Initial Catalog=Authorship;Integrated Security =True");
conn.Open();
//updating the record
SqlCommand cmd = new SqlCommand("Update Products set ProductName='" + ProductName.Text + "',ProductDescription='" + ProductDescription.Text + "',ProductQuantity='" + ProductQuantity.Text + "', ProductPrice='" + ProductPrice.Text + "' where ProductID='" + userid + "'", conn);
cmd.ExecuteNonQuery();
conn.Close();
//Setting the EditIndex property to -1 to cancel the Edit mode in Gridview
GridView1.EditIndex = -1;
//Call ShowData method for displaying updated data
gvbind();
}
i don't have the product image inside a edit template and also, product image is not included in my code behind. cant understand why a text box becomes visible on product image when i click on update function. please help.
If (e.Row.RowState And DataControlRowState.Edit) > 0 Then
for example
Protected Sub GridView1_RowDataBound(sender As Object, e As GridViewRowEventArgs)
Handles GridView1.RowDataBound
If e.Row.RowState = DataControlRowState.Edit Then
ctype(e.Row.Cells(1).Controls(0),TextBox).Enabled=False
End If
End Sub

}
I am getting empty value when I debugging this code.I think my code is correct but how i am not getting value of textboxes, i don't understand. Please help me for solving my issue.
Thanks in advance.
You probably did not wrap the DataBind() of the Gridview inside an IspostBack check. If you do not then the values will be rested by the DataBind instead of being saved with ViewState.
protected void Page_Load(object sender, EventArgs e)
{
//not here
TrackerGrid.DataSource = source;
TrackerGrid.DataBind();
if (IsPostBack == false)
{
//but inside an ispostback check
TrackerGrid.DataSource = source;
TrackerGrid.DataBind();
}
}

I've modified you code little bit by handling null conditions. Please have a look.
protected void OnRowCreated(object sender, GridViewRowEventArgs e)
{
subTotal = 0;
if (e.Row.RowType == DataControlRowType.DataRow)
{
DataTable dt = (e.Row.DataItem as DataRowView).DataView.Table;
int itemId = Convert.ToInt32(dt.Rows[e.Row.RowIndex]["ItemId"]);
total += Convert.ToDecimal(dt.Rows[e.Row.RowIndex]["Total"]);
if (itemId != currentId)
{
if (e.Row.RowIndex > 0)
{
for (int i = subTotalRowIndex; i < e.Row.RowIndex; i++)
{
Label lblViewTotal = (Label)e.Row.FindControl("lblViewTotal");//First Get label
if (lblViewTotal != null && lblViewTotal.Text != string.Empty) //Check whether it is null or not
{
subTotal += Convert.ToDecimal(lblViewTotal.Text);
}
}
this.AddTotalRow("Sub Total", subTotal.ToString("N7"));
subTotalRowIndex = e.Row.RowIndex;
}
currentId = itemId;
}
}
}
Are you sure that OnRowCreated Triggers after OnDataBound ?
It may be that there is no value at the stage when you are doing the sub total.
Try using the RowDataBound event instead?
(Been a while since I did web forms work, so this is from memory, apologies if I am incorrect)
I have a gridview and i'm trying to create an insert footer. The data inserted must be unique so i have created a custom validator. The problem is that i can;t fire the validator when I am pressing the linkbutton.
<asp:TemplateField HeaderText="id" SortExpression="id">
<EditItemTemplate>
<asp:Label ID="Label1" runat="server" Text='<%# Eval("id") %>'></asp:Label>
</EditItemTemplate>
<ItemTemplate>
<asp:Label ID="Label1" runat="server" Text='<%# Bind("id") %>'></asp:Label>
</ItemTemplate>
<FooterTemplate>
<asp:LinkButton ID="LinkButtonInsert" runat="server" OnClick="updateData">Adauga</asp:LinkButton>
</FooterTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="name" SortExpression="name">
<asp:TemplateField HeaderText="name" SortExpression="name">
<EditItemTemplate>
<asp:TextBox ID="TextBox1" runat="server" Text='<%# Bind("name") %>' ></asp:TextBox>
</EditItemTemplate>
<ItemTemplate>
<asp:LinkButton ID="LinkButton1" runat="server" Text='<%# Bind("name") %>' PostBackUrl='<%# "~/login.aspx?UserID=" + Eval("name") %>'>
</asp:LinkButton>
</ItemTemplate>
<FooterTemplate>
<asp:TextBox ID="TextBoxName" runat="server"></asp:TextBox>
<asp:RequiredFieldValidator id="RequiredFieldValidator" runat="server" controlToValidate="TextBoxName" Text ="*" ValidationGroup = "INSERT"
ErrorMessage="Introduceti numele categoriei" forecolor="red"></asp:RequiredFieldValidator>
<asp:CustomValidator ID="CustomValidatorText" runat="server" ErrorMessage="Exista deja categoria" controlToValidate="TextBoxName" ValidationGroup = "INSERT"
forecolor="red" OnServerValidate="CheckCategoryAvailability"></asp:CustomValidator>
</FooterTemplate>
</asp:TemplateField>
Here is the backgroud code:
protected void CheckCategoryAvailability(object source, ServerValidateEventArgs args)
{
SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString);
con.Open();
string textBoxName = ((CustomValidator)source).ControlToValidate;
var textBox = ((CustomValidator)source).Parent.FindControl(textBoxName) as TextBox;
string txt = textBox.Text;
Response.Write(textBox.Text);
SqlCommand com = new SqlCommand("select count(*) from Chapter where name = '" + txt +"';", con);
Response.Write(com.ExecuteScalar());
int temp = Int32.Parse(com.ExecuteScalar().ToString());
if (temp == 1)
{
args.IsValid = false;
}
else
{
args.IsValid = true;
}
}
protected void updateData(object source, EventArgs args)
{
Response.Write(Page.IsValid);
}
You have to place the ValidationGroup attribute also in the LinkButton tag:
<asp:LinkButton ID="LinkButtonInsert" runat="server" OnClick="updateData" ValidationGroup="INSERT">Adauga</asp:LinkButton>
Easier Option
Copy custom Validator with different ID but calling the same function passes the textfield value as args parameter
<asp:CustomValidator ID="CustomValidator1" runat="server" ControlToValidate="txtBusinessName" ErrorMessage="Invalid Text Entered" CssClass="alert-danger" OnServerValidate="customvalidator1_ServerValidate"></asp:CustomValidator>
<asp:CustomValidator ID="CustomValidator2" runat="server" ControlToValidate="txtAddress1" ErrorMessage="Invalid Text Entered" CssClass="label-danger" OnServerValidate="customvalidator1_ServerValidate"></asp:CustomValidator>
Protected Sub customvalidator1_ServerValidate(source As Object, args As ServerValidateEventArgs)
If args.Value.contains("X") Then
args.IsValid = False
End If
End Sub

and this is the code behind:
protected void insertingmodeevent(object sender, EventArgs e)
{
string gruppoAdmin = System.Web.Security.FormsAuthentication.Decrypt(Request.Cookies[1].Value).UserData;
if (gruppoAdmin.Contains("SPGAdmins"))
{
try
{
DropDownList dd = new DropDownList();
dd = DetailsView1.FindControl("ddlIDCommerciale") as DropDownList;
dd.SelectedIndex = 1;
dd.SelectedValue = "1";
}
catch (Exception)
{
new Exception();
}
}
else
{
// other code
}
}
The code is execude regularly but if I check the data on the Database, the Item does'ent take the value forced on the code behind. I tried also with The event OnDataBinding but the result is the same.
How can I force the value for this field?
A possible solution is to add an event OnItemInserting on the entitydatasource of my gridview. Then I used this code:
protected void UpdateDataSource(object sender, EntityDataSourceChangingEventArgs e)
{
if (!gruppoAdmin.Contains("SPGAdmins"))
{
SalesPortalModel.PianificazioneIncontri pianificazione = e.Entity as SalesPortalModel.PianificazioneIncontri;
int idCommerciale = (from a in entity.Commerciali where a.Nome == Context.User.Identity.Name select a.IDCommerciale).First();
pianificazione.IDCommerciale = idCommerciale;
detailsView1.Rows[1].Visible = false;
}
}
