Forms Data Controls :: Hide Column In A Dynamically Created Grid View?

Jul 23, 2010

I have a dynamically created grid view in the load even of my web page. I am setting its data source at run time like

gv.datasource = someObject.getItems();
gv.dataBind();

Now I wanted to hide, that is to make some of the columns visible false.

First how can I do that, Second should I write the code in the same page_load event or I should write the code some where else, cause when I add this line of code

gv.colums[0].visible=false;

an exception is produces "Argument out of range"

Forms Data Controls :: How To Bind Grid View Columns Dynamically

Feb 9, 2010

I 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?

Forms Data Controls :: Create An ASP Grid With Dynamic Columns With An Ability To Freeze Columns And Rows

Sep 20, 2010

I created a gridview that is made up of 4 gridviews and using a stored procedure to populate it. I create columns at runtime because the number of columns changes all the time.To make the grids editable I am adding template fields at runtime as I create the columns, this is to ensure that a user is able to edit the cells and some foot values update. Reason why I have four grids is to freeze rows and columns like in excel using javascript. The problem is that performance is very bad especially in IE, the grids take a long time to load. I am not sure if this is caused by the data load or the creation of text boxes. see some of the code below for my _aspx page:

Forms Data Controls :: How To Access To Grid View Columns Properties

Jun 25, 2010

I have search for a long long time and could not find a solution to access to grid view's column properties. I have binded a grid view through this method, the bindGridView function will return a table with columns and rows.

The problem here is I cound not access to columns properties such as Grid_View.Columns.Count or Grid_View.Columns[0]."something". It seems like the grid_view does not have any column. But I can access to the Rows properties.

I have put this code within a (!IsPostBack) and set the AutoGenerateColumns to true?

I need to access to columns badly as I need t add additional column to the binded grid view.

Forms Data Controls :: Displaying Totals For Columns In A Grid View?

Jul 13, 2010

I have developed my application using ASP.NET with Visual Basic. I have a table that contains 3 fields. The name of the table is "Customer" and the names of the fields are "Name", "Address", and "Amount". I have a gridview that displays these three columns. I want to summarize the value in the "Amount" column for each record and display the summarize value in the footer of the "Amount" column.

I added some code to the "ItemTemplate" and "FooterTemplate" of the template for the "Amount" field and wrote two functions One function adds the value of the "Amount" field to a variable called "TotalAmount" and the second function 'gets' the value stored in the "TotalAmount" variable.

I am not getting any error messages and all of the items are displayed in the gridview but I am not displaying anything at the bottom of the "Amount" column. What more do I need to do?

This is my code for the "Amount" template:

<asp:TemplateField
HeaderText="Amount"
SortExpression="Amount">
<EditItemTemplate>
<asp:TextBox
ID="TextBox1"
runat="server"
Text='<%# Bind("Amount") %>'></asp:TextBox>
</EditItemTemplate>
<ItemTemplate>
<asp:Label
ID="Label1"
runat="server"
Text='<%# Bind("Amount", "{0:c}") %>'>
<%#SumAmount(Eval("Amount")) %></asp:Label>
</ItemTemplate>
<FooterTemplate>
<%#GetTotalAmount() %></FooterTemplate>
<FooterStyle
BorderColor="Black"
BorderStyle="Solid"
/>
</asp:TemplateField>
This is the code in my .vp file
Dim TotalAmount as decimal 0.0
Function SumAmount(ByVal Amount
As
Decimal)
As
Decimal
TotalAmount = TotalAmount + TotalAmount
End
Function
Function GetTotalAmount()
As
Decimal
Return TotalAmount
End
Function

Forms Data Controls :: Selecting Rows From A Grid View?

Oct 17, 2010

How do you select value from a gridview? I would like to pass values of rows selected to a query with the code below, but the grid seems to be frozen and I can't find a property for the grid that allows me to select rows.

Protected Sub GridView1_SelectedIndexChanged(ByVal sender As Object, ByVal e As EventArgs) Handles GridView1.SelectedIndexChanged
Dim DB As New AOP29DBDataContext
If GridView1.SelectedValue = "Receiver" Then
Dim Query = From p In DB.Receivers
Select p
GridView2.DataSource = Query
GridView2.DataBind()
End If
If GridView1.SelectedValue = "Donor" Then
Dim Query = From p In DB.Donors
Select p
GridView2.DataSource = Query
GridView2.DataBind()
End If
End Sub

Forms Data Controls :: Setting Visibility Of TemplateField Columns In Grid View?

Oct 27, 2010

i have a grid view with all columns as TemplateFields( No BoundField). Based on certain condition i have to set Visibility of few columns false. Suppose when there is no column 'CaseList2' in the DataTable, then the second column of the grid (whose column index is 1 )should be invisible. But when the Gridview binds it gives error DataBinding: 'System.Data.DataRowView' does not contain a property with the name 'CaseList2'

i googled it and found that

GridView1.Columns[1].Visible = false;

should work. But its not working actualy.

Forms Data Controls :: Grouping The Data Rows Of The Grid View Under The Column Selected?

Sep 22, 2010

I have a grid view that needs to be shown group wise. The grouping of the data should be dynamic and that is based on the column that is selected.

In general it should list all the rows and based on the coloumn header selected, all the rows should group by that column and should be listed under it. That also needs the template column for the check box and while group by there should be a check all option available for each group.

Even having the collapse and expand option for each groups is required.

I currently use VS 2005 and later will use 2008 and 2010, but will use the aspx code and not xaml.
