Forms Data Controls :: Use Gridview Method "setPageIndex"
Jan 21, 2010
I have a search page with a GO button. The user enters his search term in a text box, then he clicks on GO, and a Gridview gets populated with database records that match. The problem is this. Suppose there are several pages of data, and the Gridview has page-numbers at the bottom and the user clicks on page 4. He views whatever is on page 4. Then he decides to do another search, this time for some other word. He clicks GO, and the gridview populates, but the page still is page 4 (though for the new data). When he does a new search, I want the gridview to be on page 1. I found a method for gridview called "setPageIndex", but the question is where to do that. Should I set the page index in the GO button code, or in the databound event of the Gridview, or somewhere else? I find that if there are no records, and I do a "setPageIndex", that the program crashes. I also find that it doesn't seem to do anything when I put it in the GO button code.

<asp:TemplateField>
<ItemTemplate>

CommandName="Delete" runat="server">

I am trying to create an event with a gridView and a c# method. So far I am getting this error:
CS1061: 'ASP.contentpage9_aspx' does not contain a definition for 'ImageGridView_OnSelectedIndexChanged' and no extension method 'ImageGridView_OnSelectedIndexChanged' accepting a first argument of type 'ASP.contentpage9_aspx' could be found (are you missing a using directive or an assembly reference?)
Here is the asp markup:
<asp:GridView ID="ImageGridView"
DataSourceID="ImageSqlDataSource"
AutoGenerateColumns="false"
DataKeyNames="ImageID"
OnSelectedIndexChanged="ImageGridView_OnSelectedIndexChanged"
RunAt="Server">
And my c# method:
void ImageGridView_OnSelectedIndexChanged(Object sender, EventArgs e)
{
ImageDetailsSqlDataSource.SelectParameters["ImgID"].DefaultValue =
ImageGridView.SelectedValue.ToString();
ImageFormView.DataBind();
}

i have a dynamic data layer, i.e every user can add custom fields to database tables, so i need dynamic methods in my application.
i know i can use params to specify a variable number of parameters for a method, but the gridview in asp.net looks for a method with the same fields it is updating, i.e if gridview updates fields :name, age, phone, email(suppose email is a custom field of a certain user i.e it doesn't exit for another), and the object data source calls the update method with signature : (name, age, phone, params object[] custom_attributes) an error is generated that the gridview can not find the method with the signature(name, age, phone, email)

I have created a web app with a gridview that is connected to an sql data source to extract data. The web app consists of two pages (default.aspx and rategrid.aspx). On the default page i have a button that when clicked it displays rategrid page with the gridview data. On rategrid page I also have two buttons (one to go back to default page and one for export to word). When I click the word button, i get error (Control 'GridView1' of type 'GridView' must be placed inside a form tag with runat=server.).I have already looked at references online that reference to put (Public Overloads Sub VerifyRenderingInServerForm(ByVal control As Control) in code for Word button. However, I am still getting the same error.

is it possible to have a button that points to a method you have defined in codebehind, that passes in a record from the row as a parameter? for example, id.something like:
<asp:CommandField ButtonType="Image" EditImageUrl="/editbutton.jpg" ShowEditButton="True" OnClick="editRow(int id)"/>
it wouldnt necessarily 'edit' this row. i'd like it to instead load an editable grid corresponding to the id passed.

In a GridView control ASP.NET
OnRowDataBound="gvTest_OnRowDataBound" followed by
protected void gvTest_OnRowDataBound(....){}
OR
Text='<%# BindMyData(DataBinder.Eval(Container,"DataItem.Price"), DataBinder.Eval(Container,"DataItem.CurrencyID")) %>'
followed by
protected string BindMyData(object price, object currencyID)
{...}
Which one is best in terms of performance and coding best practice?

Is there an equivalent of the GridView.RowDataBound event for the DetailView and FormView controls in ASP.NET 3.5?I need to manipulate data after Selecting it from my database, but before it gets presented to the user. I've read the documentation but I think I've missed something because I can only find FormView.DataBound which is called after the entire control has been data bound. Something like an ItemDataBound event would be what I need....?!?

Got a little dilemma I could use some guidance on. I'm trying to call an Interface method that resides in my Business Layer from within the template of a gridview in the same manner as below:
<%# GetEmployee(Eval("EmpId"))%>
i.e. it reads as follows:
<%# BusinessLayer.IEmployee.GetEmployee(Eval("EmpId"))%>
I'm actually getting the following error:
"An object reference is required for the non-static field, method, or property"
Which makes sense as I haven't instantiated as instance of the Interface. So the queston is how do I do it?

I am using VS 2008 SP1. My also have included CSS Friendly adapter [URL] in my project ( I mentioned this because my GridView Empty data template is not showing when using GridView's CCS Friendly adapter). I have a GridView and a DetailsView. When a record in GridView is selected its details information is shown in the Details View. Type of Data source I am using is ObjectDataSource. My Insert and Update methods works perfectly. It is only the Delete method that is passing null values to the underlying object delete method. My source codes for both the UI, BLL, DAL is shown below

I am using an application from a book for a shopping application , to adapt for my own learning, but there seems to be a problem with the shopping cart page. This is a section I have not changed as there is no need to but there is an error. In the code behind the only thing new is the namespace:
namespace OIClothing
{
public partial class Cart : System.Web.UI.Page
{
ShoppingCart cart; // it doesn't like this, giving the debug message the type or namespace 'Shopping Cart" could not be found
protected void Page_Load(object sender, EventArgs e)
{
CheckTimeStamps();
if (Session["cart"] == null)
{
cart = new ShoppingCart();
Session["cart"] = cart;
}
else
{
cart = (ShoppingCart)Session["cart"];
}
GridView1.DataSource = cart.GetItems();
if (!IsPostBack)
GridView1.DataBind();
btnCheckOut.Enabled = (cart.Count > 0);
}
protected void GridView1_RowDeleting(object sender, GridViewDeleteEventArgs e)
{
cart.DeleteItem(e.RowIndex);
GridView1.DataBind();
}
but when running the page, this error is given: CS1061: 'ASP.cart_aspx' does not contain a definition for 'GridView1_RowDeleting' and no extension method 'GridView1_RowDeleting' accepting a first argument of type 'ASP.cart_aspx' could be found (are you missing a using directive or an assembly reference?)

I have extended GridView in order to have consistent look & feel, paging and sorting. However, when the page is first time loaded, the select method is getting called twice. It works fine when i move between pages in pagination.

I have a gridview, which on the row data bound method that inserts a row when comparing values on a particular field. If the two values are different, a new row is inserted, if not no row is inserted. This coding is working as a grouping gridview, and is working correctly. However, I have problem, and problem is counting the rows between each group, which I want to display in my blank row between each group, the value of which I am holding in a hiddenfield.
When I try to do it, the first group doesn't show the result, but is displayed on the next group. I am pretty sure that I am doing something wrong. My approach is that if the value between the last row and the existing row are different, then the value is one, on the next row data bound event, if the values are the same then the value is increased by one, else the value is one because it is a new group. Here is my code:
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
Table tbl = e.Row.Parent as Table;
TableCell cell = new TableCell();
CheckBox chk = new CheckBox();
Label lbl2 = new Label();
HiddenField rowValue = new HiddenField();
if (e.Row.RowType == DataControlRowType.Header)
{
e.Row.Visible = false;
}
else
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
Session["count"] = 1;
Label lbl = (Label)e.Row.FindControl("lblValue");
string str1 = ((Label)(lbl)).Text;
string prevStr= (string)Session["previousStr"];
if (prevStr== str1)
{
lbl.Visible = false;...................
