View 1 RepliesIt 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 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?
using for Loop I bind data to data table
DataTable dt = new DataTable();
DataColumn dcIn = new DataColumn("IN");
DataColumn dcOut = new DataColumn("OUT");
DataColumn dcDuration = new DataColumn("DURATION");
dt.Columns.Add(dcIn);
dt.Columns.Add(dcOut);

I am trying to bind a table to my grid view. This grid view has an extra column Serial Number where I want to show numbers starting from 1 till the last entry.
View 4 RepliesI am developing an application using ASP.NET with C#.NET.in my application i have a gridview control and radobutton list having the values as Manufacturer and Distributor. based on the radiobutton selected value,the gridview will bindedup.
i am using SQL SERVER 2005 as backend server. in my database i have one table with columns as
1.mfropendate
2.mfrclosedate
3.mfrawarddate
4.distopendate
5.distclosedate
6.distawarddate
My gridview has 3 columns as Opendate,closedate,awarddate.
if user select the radiobutton as manufacturer,only mfropendate,mfrclosedate,mfrawarddate have to bind. and if user select the distributor the remaining 3 fields will have to bind. for that i had write a storedproc as create procedure sp_GetDraftBids as begin select mfropendate as opendate,mfrclosedate as closedate,mfrawarddate as awarddate, distopendate as opendate,distclosedate closedate,distawarddate awarddate from draftbids end GO
i.e i had taken the alias names for that fields so that i will bind the only 3 columns to grid view as opendate,closedate,awarddate.
My gridview code is
[Code]....
here i had taken the same alias names as i have to bind only 3 columns to gridview.when i run my application i am getting the records in data table with column names as opendate,closedate,awarddate,opendate1,closedate1,awarddate1.i.e it does not allow the same alias name.
for two radio button conditions i.e for manufacturer and distributor the gridview binded with opendate,closedate and awarddate columns as i had binded the gridview boundfields withat names.
but when user select the distributor radiobutton i have to bind the opendate1,closedate1 and awarddate1 to the gridview. for that should i can i change the storedproc are any other solution is there?
I retrieving user selected values from my first page with session.
I need to list product details whcih user selected separately. I mean if user selected
Products 1,5,7 Second page listing product details separately 1,5,7 in gridview1, gridview2, gridview3.
Problem is when ever i try to bind the gridview using the Sql data source and calling SP.
Its not displaying anything on the screen, where as i tested the SP, its working fine.
But when i write the Select statement in Sql data source... Its working fine.

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.

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.
In My project i want to use the mvccontrib [URL] to auto generate grid by passing the DataTable to the Grid. Currently Grid does not support this. Grid takes IEnumerable(Of T) and auto generate columns. Is their any way i can achieve this by passing DataTable. Or How do i convert the DataTable to IEnumerable(Of T). My DataTable is completely Dynamic i don't know number of columns or names of the columns at design time. DataTable completely dynamic number of columns are not fixed it just any DataTable. In Short i want to convert Dynamic DataTable to IEnumerable(Of T). Or Is their any better way.
1) One way i tried is using .net 4.0 Dynamic, DynamicObject and ExpandoObject I created a dynamic class as shown here [URL]. I trid passing IEnumerable(Of SampleDynamicObject) but BuildColumns() method is not able to find out the proprieties dynamically added on to it.
2) I think Second way to modify the AutoGenerateColumns() method to work with DataTable, But it looks impossible as Grid Get initialize using IEnumerable(Of T) and all the call on grid for method is using IEnumerable(Of T). So it's come down to converting DataTable to IEnumerable(Of T) and my DataTable are dynamic i don't know their structure at design time So i can't write any specific class to create a object and convert DataTable to IEnumerable(Of T).
I want to bind a grid view by code not by wizard.

My DataTable is programatically generated, and contains objects of type JobInstance in the cells.
[Code]....
When I bind this DataTable to an ASP GridView, it only displays the first column. But if I remove the "typeof(Job)" when creating the column (the line with // !!!), the GridView displays all the columns by showing the result of JobInstance.ToString() in the cells. However, I have no access to the underlying JobInstance object, only the string values that are being displayed.
I need access to the JobInstance object when displaying the GridView (for example in the OnRowDataBound), because I want to access the fields inside JobInstance for each cell to determine formatting options, and add other links in each cell.
I have a data table, in one of the column, I will have this data, I will bind the data table to a grid view. I was hoping that this column change to a hyperlink. But, it was display the entire text.
<A HREF="page_url">Remark(s)</A>
When I view the page source code, I saw this:
<A HREF="page_url;Remark(s)</A>
How to correct this?

View 5 RepliesI 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:

I also tried using FindControl() but iam not able to proceed further.
This is driving me nutty... I have a gridview on a page. On the same page is a web user control with several public properties. Using the gridview's selectedindexchanging event, I try to set the user control property, but it's always null. Like this:
protected void grdPhysicians_SelectedIndexChanged(object sender, EventArgs e)
{
usercontrol1.ID = grdPhysicians.SelectedValue.ToString(); [code]....
If I write the grdPhysicians.SelectedValue to the page, I can see it's there. It just won't pass to the web user control.What I'm trying to do is have a master record form with child records in a web user control and just pass the selected record id into it.
protected void grdPhysicians_SelectedIndexChanged(object sender, EventArgs e)
