Fetch Data From Gridview In ItemTemplate In ASP.NET 2
Nov 1, 2011
I have a gridview where each columns have two template fields. One is ItemTemplate and another is EditItemTemplate. Now in EditItemTemplate it will show some textboxes where i can perform necessary editing. I can easily fetch data from each cell by using the following code-
[code]...
But how can i fetch data when the grid view is not in editing mode that is in ItemTemplate. I have tried the following-
[code]...
But its getting the exception object reference is not set to an instance of object. This is probably happening because the above code should be used in a method like RowDataBound when a row is instantiated. But I have to fetch data from some other method.Again for clarification I want to fetch data when the gridview columns are in ItemTemplate Mode.
I am a newbie in VB.net(programming). I need your advice regarding Gridview control.
I have a gridview loaded with two columns-one column(Name)is with some Text,another(Price) is empty.
I have got a TextBox with the data of Name and Price.
Now,I would like to loop through the Textbox,and see if the Data/symbols of the Column(Name) of GridView Control matches with the Data in Textbox.
If the Names of the GridVies First Columns data matches with the names of the Textbox,then the Price data should be fetched in the Second Column(Price) of GridView.[code]...

<asp:TemplateField HeaderText="Action"> <ItemTemplate> <asp:ImageButton runat="server" ID="acceptBooking" ImageUrl="~/images/accept.png" OnClientClick="if (!window.confirm('Are you sure you want to accept this booking?')) return false;" /> </ItemTemplate>
I have a gridview as shown below. When the EmpType is contract the EmpID must be masked as "XXX"; for regular employees, actual EmpID should be shown. Also, when it is masked, I need to add a button control in the EmpID column.I need to do it using mark-up; not using code behind. How can we write the conditional logic for Gridview's ItemTemplate for this logic?Note: .Net 4.0

I am developing one desktop application using vb.net 2008 and Microsoft SQL Server 2005. fetching the data from database between a given range.
the date field in my table is of type VARCHAR(25) and the date format stored is dd-mm-yyyy. when I using the between clause in the SQL query then it is not giving all the data every time i.e. the date criteria in where clause is not working fine.
while my clients requirement is to keep the date format as dd-mm-yyyy and fetch the data according to the given range.
I search on the forum and found many queries to fetch the data by converting or type casting the date field within sql query but nothing worked.
The table structure that I am using is as follows
USE [Firm_master] GO /****** Object: Table [dbo].[tblTransaction] Script Date: 05/17/2011 21:49:11 ******/
I have a checkbox in my application,when the checkbox is checked then i want to fetch the data from the database and add it to the dropdownlist of the combobox.Again when the checkbox is unchecked then i want to ramove all the data from the dropdownlist of the combobox.
I did this
Private Sub CheckBox1_CheckedChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles CheckBox1.CheckedChanged If CheckBox1.Checked = True Then con = New OleDbConnection("Provider=Microsoft.Jet.Oledb.4.0;Data Source=Etech.mdb")
[CODE]...
When the checkbox is checked then the data is added from the database to the dropdownlist of the combobox but when i uncheck it then the data is not removed from the dropdownlist of the combobox. In the above code i think i need to add an else condition to remove the data from the dropdownlist of the combobox and make it empty when the checkbox is unchecked.......but i cant give the proper else condition in the above code.
In my application, I have been getting this error each time the treeView loads it's items. This error makes my application slow on load and takes at least two minutes to load.The error is: System.Windows.Data Error: 26 : ItemTemplate and ItemTemplateSelector are ignored for items already of the ItemsControl's container type; Type='TreeViewItem'
My xaml code for the treeview is: (I'm using VB.net on my ViewModel)
I have a Repeater on one of my pages like so: [code] But, when I run it it errors out with the message:'btn<% Container.DataItem %>' is not a valid identifier.I want to append btn to the Container.DataItem value so that I have dynamically assigned control names that are associated with the underlying data item. Any ideas?
I have the following code. It works as is, but... I am not always going to have an even number of items in the RSS feed So, at the end of the table, I might have only one table cell on the last row. So, is there a way to count the number of ItemTemplates and AlternatingItemTemplate, so if it is an odd number I would be able to add another cell <td> </td></tr> and close the table row?
I have the following inside a formview, I want to be able to show the information and if anyone makes changes I should update this information by clicking on update.I am fairly new to asp.net development , how can I do it? I keep having exception, saying frm1 is expecting editmode.
I use Visual Web Developer 2008 Express.I have Label1 in a DataList ItemTemplate. I wish to use a button to get the text from that label and add it to text in TextBox1 which is elsewhere on the page.
I know how to do this from a standard label on a ASP.NET web page but cannot work out how to get the text from a label inside a DataList ItemTemplate.
This is what I thought I should do Protected Sub submit_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles submit.Click TextBox1.Text = TextBox1.Text & " " & DataList1.ItemTemplates.ItemTemplate.Label2.Text End Sub
I thought that because DataList1.ItemTemplates.ItemTemplate.Label2 - System.Web.UI.WebControls.Label is what is written in the properties window header when I select the label in the DataList template.
When I try that, I get a Blue Squiggle under "DataList1.ItemTemplates" and if I hover over the squiggle the error box comes up saying " 'ItemTemplates' is not a member of 'System.Web.UI.WeControls.DataList'
I'm a newbie in asp.net. When using FormView, there is a big amount of code in ItemTemplate, EditItemTemplate and InsertItemTemplate which is almost identical.

ListView allows the use of LayoutTemplate - but I didn't see any examples that insert this kind of code in LayoutTemplate. And inserting this code in LayoutTemplate would result in an error.DetailView allows to produce code automatically but I'd like to use a specific design (for ex. using "fieldset" that encompasses some fields).
Okay, so I wrote a few custom ItemTemplates for VS2010 that implement IWizard in VB.NET (4.0). Straight forward enough. They work during my testing, but when someone else deploys and attempts to use any of them, Visual Studio throws an incredibly generic Exception has been thrown by a target of invocation error.
Stranger still, after they open up the project properties and try again... they work. Without changing anything. Anyone have any clue what is going on? Or perhaps even just a way of getting VS to give me a more specific error? I already tried devenv.exe /log but nothing out of the ordinary was there.
How can I create alternating background colors for listview rows while only using ItemTemplate? I don't want to use AlternateTemplate because I would have to edit both of them everytime I want to change something when all I'm using it for is to create the alternating background colors. So what's a way I could do it using only the ItemTemplate?
