I have no clue what I'm doing wrong here, but I wanted to create a grid view based on a return from a tableadapter.
[Code]....
[Code]....
Also, maybe I should be going about this another way as I wanted to add a drop down to each record and a link to each record.On pointers on how I should do this would be great too.
I have the following code
Imports System.Data
Partial Class Students_AddWishes
Inherits System.Web.UI.Page
Public dt As New DataTable
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
dt.Columns.Add("ID", System.Type.GetType("System.Int32"))
dt.Columns.Add("univirsity", System.Type.GetType("System.Int32"))
dt.Columns.Add("major", System.Type.GetType("System.Int32"))
End Sub
Protected Sub btnAdd_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnAdd.Click
Dim row1 As DataRow = dt.NewRow()
row1("ID") = dt.Rows.Count + 1
row1("univirsity") = ddlUnivs.SelectedValue
row1("major") = ddlMajors.SelectedValue
dt.Rows.Add(row1)
GridView1.DataSource = dt
GridView1.DataBind()
End Sub
End Class
the problem is it shows only one row or record. How to make it shows many records?
the code is like,
namespace DataControlsSample.App_Code.PL
{
public partial class GridView : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
[Code]....
the data table is getting rows ,as i had chked ,,,but grid view is not getting displayed ..wat could be the problem?
I have an gridview consisting pager Templet. In pager templet, add first, previous,next and last Buttons to control records. PageSize is 3. First I am binding first 3 records from the list (Consisting 9 records) to the GridView.
My question is:
<1> Is it possible to bind the next 3 records(record4, record5,record6) to GridView when click on next Button?
<2> Similally, Is it possible to bind records for other buttons?
as we all know
Dataset ds=new DataSet();
gridview1.datasource=ds;
when the dataset has no reccrds then the grid view will not displayed.
I need to show the grid with 10 rows with no details means empty records.
I have a grid view and I added edit and Save buttons to it. When I click on edit I am able to edit the data but when I click on save I amgetting the data before edit.
Please see my code below.
Eg: I have start date as 2005-10-10 12:00 AM so After I click On edit it is letting me to edit, So If I edit the start date to 2010-10-10 12:00 PM and click on the save button I am stil getting the old start date. which is 2005-10-10 12:00 AM instead of 2010-10-10 12:00 PM

I would like any row in my gridview where the boolean field "Approved" is True to be shaded gray. Here is the code that I'm using, but every row ends up being gray, regardless of the value in that "Approved" field. My guess is that I'm not correctly evaluating the boolean value in this field (which is actually a yes/no field in MS Access), Not sure if I should be reading that value as "-1", "Yes" or "True" or "NotNull"? Anyway, here is the code:

I am doing a online web application whereby user is able to enter in new template as well as search for template. The Add template is located outside the grid view and if user clicks on the button, it will load the grid view that is populated with data as there is a row of empty fields at the bottom. However when I click on the Add Template button, the grid view does not appear.
This is my business logic that I used it to search for records as well to click on the Add Template button to add in new records:

We are in the process of migrating our current asp.net gridviews to silverlight grids. The challenge that I am facing here is that in the gridview, the grid is bind to a dataset/datatable. But in silverlight, I do not have dataset/datatable available in the silverlight class. So only option is to create a Webservice and convert the dataset that I am currently getting from business layer to a class that imlements IList<> (unless there are any other ways). Now to convert this dataset to Ilist, I have to loop through the dataset to load the List. In my current dataset I have almost 10,000 records or even more in some cases. So the response time will be really slow.Are there anyways to
1) Load the List from dataset directly without looping through ?
2) Fetch the data from database directly to a List without having loading the dataset ?
What is the difference between binding data in data grid view methods ?

Have a GridView with a templated select button hidden and using
e.Row.Attributes.Add("onclick",Page.ClientScript.GetPostBackEventReference(this.grdMaster, "Select$" + e.Row.RowIndex.ToString())); to select a row .
When user like to update the datasource he will select one row from gridview then in selected indexchanged event i would display the selected row values beneath the form under the grid , Then user will update the contents displayed from grid and click an update button which is outside the grid . After updating the displayed row , i got to get the values of the next row in the grid and display them for next updation , i'e if users maually selects row 3 from grid then he can update the values using the update button and then on update click itself i'll have to display next row contents of row 4 and this process could go on .
