Forms Data Controls :: Binding Datatable To Grid View Based On A Return From A Tableadapter?
Feb 17, 2010
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.
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?
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?
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 have a problem that is, I am calling data form database in agrid view and taht gridview contain both bounded and unbouded field now i wat to send this grid view data back to a datatable is it possible if yes then how?
I have a piece of data that has a refererence number and then account name that looks like this in the database:
111111,Member Account~222222,Trial Account
I have the data spitting out just like that in a grid view, but I am wondering if there is some C# I can put in to where it adds a column when there is a comma and another column when there is a ~ in the data?
I know that variations of this same question have been posed numerous times - but I can't quite seem to find the exact solution.
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 have a grid view with some coulmns like Name,Phone no etc with Edit,Delete column in grid view. I click a row in grid view to Edit,it goes another page where i can edit all fields .Once i update i redirect the page to gridview. I want the grid view to remain in that particular page say 4 of the grid view
It happened to add an extra Gridveiw Header in row_databound event , It did worked fine on !Postback but disappered on Page.Postback . Quick google search guided me to move the event to Row_Created event and every thing is okay .
Can any expert post some pointers , differnces between grid row_created vs row_databount with some sample table data created dynamically behaviour of both the events in !Postback and page.Postback .
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 ?
i have the dataset with one table.Table contains three column like 'Name','Location','Pin'.I would like to move the data from another table based on schema.
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 .
I have a grid view that does add, edit update and delete. ( I draged the grid to the aspx page ) it is working. I would like to have the following : once I lick on edit, I open a form inside the grid view to edit the fields. How can I do that.
I have a function that constructs a datatable from a file that the client uploads. And I want to bind that datatable to a listview but I'm not sure what I'm doing wrong... Say, the datatable is like:
FirstName LastName John Smith
Here's how my aspx looks like:
[Code]....
In my names.aspx.cs file, I do: lvNames.Datasource = dt; //dt is a datatable lvNames.DataBind();
When I run my aspx page, the listview is empty, is there something obvious I'm doing wrong?
