View 13 RepliesI have a datagrid view on a web page that I'd like to be able to have a user "select" an item and then open another page. I've tried looking through some online documentation, but I haven't found a really efficient way to do what I want yet.
Here is my code so far:

I have a datagrid view on a page that I'm making and I want to be able to open another form when a user "selects" an entry. I've tried looking through the documentation on how to do that but can't seem to find any. Does anyone know of an easy way to accomplish this task?

and what I'm trying to do is that when users click on the SelectedIndexChanged that it takes them from this form with the item that was selected carried through to the next form, and opening a form called messageform.aspx.vb.
I have a web page with a datagridview where a user should be able to click on the selectindexchanged (in this case a "Select" button) show the results of what they have selected in a label on the second page and also redirect them to that page. Here is the code I have for the vb.net:
Imports System.Data.SqlClient
Imports System.Data
Partial Class _Default
Inherits System.Web.UI.Page
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
TimeDateLabel.Text = String.Format("Today is {0:F}", DateTime.Now)
TextBox1.Focus()
End Sub
Protected Sub whosoncallButton_click(ByVal sender As Object, ByVal e As System.EventArgs) Handles whosoncallButton.Click
Dim dt As New DataTable
Dim da As New SqlDataAdapter
Dim cmd As New SqlCommand
Dim connectionString As String = "Initial Catalog=mdr;Data Source=xxxxx;uid=xxxxx;password=xxxxx"
Dim con As New SqlConnection(connectionString)
con.Open()
cmd.Connection = con
cmd.CommandType = CommandType.StoredProcedure
cmd.CommandText = "getoncall"
cmd.Parameters.AddWithValue("@subschedule", TextBox1.Text)
Try
da.SelectCommand = cmd
da.Fill(dt)
GridView1.DataSource = dt
GridView1.DataBind()
con.Dispose()
Catch ex As Exception
Response.Write("Error:" & ex.Message)
End Try
End Sub
Protected Sub clearButton_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles clearButton.Click
TextBox1.Text = ""
GridView1.DataSource = Nothing
GridView1.DataBind()
End Sub
Protected Sub GridView1_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles GridView1.SelectedIndexChanged
Dim row As GridViewRow = GridView1.SelectedRow
Response.Redirect("Default2.aspx?msg=" + row.Cells(1).Text)
End Sub
End Class
I have also added a line to my aspx page for the event handler.
I have debugged this but no matter what I've tried so far, the SelectIndexChanged event isn't firing.
create button in the first column of the gridview with event to open a new window of web form with passing gridview row items parameters.

View 2 RepliesI have a GridView with a TemplateField where I'm hosting a button. The button has an event hanlder OnClick, so when it is clicked it will execute some code.The problem I'm having is that when I click the button in a row, the Button event handler is not excecuted right away. Instead, the GridView selectedIndexChanged is fired and then I need to click my button again to fire the button's event handler.So, is there a way I could know if the button or the row was clicked in the GridView SelectedIdexChanged event? And why the Button's event handler is not firering right away?

When I select from the first dropdown I want to populate the second. However, this is not happening. The postback is happening, but the SelectedIndexChanged handler isn't being called (I have a breakpoint which isn't being hit). The user controls are created dynamically and put into a PlaceHolder which itself is within an AJAX Updatepanel, with ChildrenAsTriggers set to true.
I'm trying to create a dynamic table (inside a gridview) with some objects. The initial creation is fine, and I store all the selectedindexes in viewstate to recreate it upon postback. This, seemingly, works fine as well, but...After the postback, when I get into the selectindexchanged even handler, I can see the new selectedindex, but the original control sending it is reset to it's initial value (because I reset them upon postback).Anyone know a fance way of doing this?Here's my code:

I have a GridView, with a DropDownList as one of the Columns. I can get the SelectedIndexChanged method to trigger - but I cannot figure out how to get other Data regarding which row this triggered on i.e. if I could get the value in the ID column (DocID below), that would be great. My code is a bit too long, so I am just posting snippets. In the *.aspx file I have:

In the *.aspx.cs File:

I am wondering if I can get the DocID from within StatusDropDownList_SelectedIndexChanged - so that I can make appropriate changes to the Database. For e.g. in the RowDataBound event, which I had a GridViewRowEventArgs e, I could easily do e.Row.DataItem - to get the DataItem, I am wondering if I get/do something similar in the SelectedIndexChanged method. (I would prefer this be not the GridView Row Index i.e. I would prefer the DataItem if possible.)
In code below, when I have more than one DIV open and I choose to sort one of the GridViews, all the other Open Div's will close automatically. How can i keep the DIV's in the state they are in when I sort any GridView?

on SelectedIndexChanged event handling of DropDownList in ItemTemplate of ListView. I put OnSelectedIndexChanged="DropDownList1_SelectedIndexChanged" in mark up, with code behind, but only to get Compiler Error Message: BC30456: 'DropDownList1_SelectedIndexChanged' is not a member of 'ASP.webform1_aspx'. How do I make it a member?
