Is there a way to add text to
[Code]....
I'm using an ASP.net 3.5 FormView. I wanted to add an unbound text box with the ID="tbxEditFormMode" and set it to "EDIT" when a user selects an existing record from a dropdown list control. Here is my code
Protected Sub ddlSelectClient_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles ddlSelectClient.SelectedIndexChanged
Dim tbxFormMode As TextBox = FormView1.FindControl("tbxEditFormMode")
tbxFormMode.Text = "Update"
End Sub
When I run it I get the following error message.
Object reference not set to an instance of an object
In the tbxFormMode.text = "Update" Line
Using Visual Web Developer Express 2010 with ASP.NET 4.0.
I have a FormView and I want to set a default value from the database. I can't get it to bind to the value in the database. My FormView looks like this:
[Code]....
The EditItemTemplate does not even load when I click the edit button on my FormView control, but I don't get an error message either.
Does anyone have an example of a formview and a gridview master detail relationship in c# ?
The gridview datasource is a datatable and the gridview is inside of the edititemtemplate of the formview.
In what event of the formview do you bind the gridview datasource?
I have a formview in which I have a dropdown list that displays a list of owners. In case the list does not have the correct owner for the user I have added functionality for them to add a new owner to the database table that populates the list. I did this by including a textbox and an Insert button in a panel. When the user clicks the new owner insert button I would like to re-databind the dropdown list so that they will see the owner they added and be able to select it.
When I add ddl_owners.databind to my button click code it gives me an error. "Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control."
I don't want to re-databind the entire formview because then it deletes all the information on the form that the user has already keyed in.
I've seen this before, I fixed long time ago and now cannot remember how I did :) My store procedure won't update the record because the sql field 'itemId' is being passed as ZERO always.
<EditItemTemplate>
<table border="0" width="100%">
<tr>
[Code]....
<td class="cxml_item_name">Active:</td>
<td class="cxml_item_value"><asp:CheckBox ID="ActiveCheckBox" runat="server" Checked='<%# Bind("Active") %>' /></td>
<td class="cxml_item_name">Created:</td>
<td class="cxml_item_value"><asp:TextBox ID="CreatedTextBox" runat="server" Text='<%# Eval("Created") %>' Width="250" ReadOnly="True"/></td>
i have a formview1 in edit mode within a modal pop up extender and Update Panel
The update statement works but on the page is a gridview1 where I want
to display the new values.
I have added the below in page code but it still does not bind
the Gridview with new values when after I click UpdateButton in Formview - Only when I refresh the page.
protected void FormView2_ItemUpdated(object sender, FormViewUpdatedEventArgs e)
{
GridView3.DataBind();
ObjectDataSource50.DataBind();
}
I have a Formview residing inside am Item Template of a Gridview. The formview is not populating, and I am pretty convinced that I am not passing the parameter properly from the Gridview to the Formview. I have listed the relevant code only, so that you can scan though it easierGridview tag:

Gridview's Datasource:

Formview's tag inside Gridview template field:

Formview's datasource:

I have a FormView with an EditTemplate.And the EditTemplate contains an ascx control:
<asp:FormView
ID="fvTicketUpdate"
runat="server"
[code]...
The contents of the ascx control has TextBox and DropDownList controls binding to the results of the FormView's ObjectDataSource through Text='<%# Eval("field1") %>'and SelectedValue='<%# Eval("field2") %>'.This works fine and I have been building all of my front end pieces like this as <asp:Panels> rendering as FieldSets that go 100% across the screen.And we call these areas "strips" accross the screen.But now I've run into a problem.One TextBox and one DropDown bind fine to a Ticket Object.But the DropDownList that works has its <asp:ListItems> hardcoded before hand.Now I have DropDownList that gets populated through a WebService in the ascx's
code behind like this:
public partial class UserControls_FormControls_PntipUpdtFaaInfo :
System.Web.UI.UserControl
{
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
[code]...
The Problem I think is the FormView is trying to do its Bind to the objectDataSource before its child ascx control is loaded in the Edit Template.And I am getting this error:
Databinding methods such as Eval(),XPath(),and Bind() can only be used in the context of a databound control.Meaning that the control must already be databound to bind the selectedValue to a Property of the TicketObject.Is there an easy way to force the order of loading to make the PntipUpdtFaaInfo control load and have its Page_Load execute and bind ddlEquip before the FormView does its first dataBind and executing its Evals?Otherwise I have to take out the eval on the ddlEquip SelectedValue attribute and go to the Parent Page and hack and force everything to happen when it needs to.This layout has worked out well for me.All of the ascx area strips across the screen share the same Validation Summary for example.It allows me to think about one section at a time and the Properties to the Business Obect and CRUD methods as I go.But this is a big brick wall I've hit.
I have a FormView which is used to insert a record into a database. Outside of this formview i have a drop down list, I want to grab the value from that drop down list and set one of the text fields within the formview to it's currently selected value. I've tried the following code, but the dynamic categorytextbox line is what seems to not be working.

I want to preset the value of a textbox within a databound formview. Tried it within codebehind on onModeChanging and onItemInserting. Method onModeChanging was fired but the textbox.text shows not the expected text. Method onItemInserting was not fired at all.
Thought to use inlinecode like
<asp:TextBox ID="txt_CREATOR" runat="server" CssClass="txtTask" Text="<%=giSessionHandling.UserName %>"/>
in the aspx but don't know how to ...
<asp:FormView
ID="frmViewDetail"
runat="server"
DataSourceID="dsrcDetail"
DataKeyNames="TASK_ID"

I have a text box inside a update panel. With the onTextChanged events, I have a post back set in "True" to show the customer Name and email when I type in the customer ID in the text box. I want to have it show when we leave or Tab out of the text box. Now is working , but only afte I click the submit button. Does anyone know how to code the following in order to make it work right away when we Tab out of the text box.
protected void txtBDID_TextChanged(object sender,
EventArgs e)
{
}
i want to bind text box that is located in dynamically created table.

I'm modifying an existing application. I need to be able to bind the Text property of an asp:DropDownList control to one of two fields when the page is rendered. The existing code is like this:
[Code]....
I've tried to use conditional logic on the .aspx page when setting the Text property, but everything I've tried results in an error. I've also tried using code-behind to set the Tetxt property in the Page_Load event. This doesn't generate an error, but it doesn't set the property either.
I have a <%Bind("prict")%> and I want to put the word Pri: in front of it but, it even appears if this field is null. How do I do this?
View 1 RepliesI have a datalist control
In it, I have a hyperlink that im binding the url, and the text to from a mysql database
here is my code so far
<asp:HyperLink ID="HyperLink1" runat="server"
NavigateUrl='<%#Bind("topicid") %>' Text='<%# Bind("title") %>'></asp:HyperLink>
Now, the problem is, the field "topicid" returns a number, such as 3. I want to add the following text before it: viewTopic.aspx?id=
So, ideally, i want something like this
<asp:HyperLink ID="HyperLink1" runat="server"
NavigateUrl='<%# "viewTopic.aspx?id=" + Bind("topicid") %>' Text='<%# Bind("title") %>'></asp:HyperLink>
But, when I do it that way, I obviously get an error.
So, is there any way to solve this problem without having to modify the database?
I have a FormView that is loaded with a records from my DB. Some of the fields may be blank or null. I am trying to check the value of some of the text boxes to verify that the user has updated the fields prior to allowing a DB update from the Edit Template.
I can not seem to get the correct syntax on the if statment to check the value of the text box....

Is it possible to get the value of the label CompanyTextLabel from CompanyTextBox using just ASP.NET expressions or something similar without writing c# code in .cs file?
