Forms Data Controls :: Post Back With Text Changed Events Under FormView Control?
Aug 3, 2010
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 need to process surveys. I have modelled them in SQLServer, just need to generate the forms to input it.I have nested SqlDataSource/DataLists. The outer gets the questions and the inner gets the various options as a plain HTML radio buttons. I can't use ASP.NET radio buttons because of a bug with them inside itemtemplates not mutually exclusive http://support.microsoft.com/default.aspx?scid=kb;en-us;316495Anyway, so now I need to know the which radio buttons were selected so I can insert the values in the database. What is the best way of doing it?

I'm new to ASP.net 3.5 and testing functionality before developing an asp.net web site. I created a page with a formview. I added several text boxes. I created an event on the FirstName_TextChanged event and added a stop in the sub. When I open the page in the browser and type in some text in the FirstName and press tab, nothing seems to fire.
1) Is this supposed to fire on the client side when text is changed?
2) If so, would the vb.net code entered work like Javascript code on the server?
3) If so again, is it possible to update another textbox based on the text entered into the FirstName on the Client Side (would do this in Javascript in Classic ASP)?
I think I'm totally confused. I've been searching web for article about how to do this.

With asp.NET control dropdownlist, there is a property AutoPostBack, if it is set "True", the whole page will be posted back.
If the aspx page include a html element "select" like:
<select id="list" name="list" runat="server"
DataTextField="Name" DataValueField="ID" ></select>
and it data is filled by code-behind.
Question is: how to allow this Select have AutoPostBack function too?

I have used update panel and in that update panel I have kept ASP Table control in which I am creating rows dynamically which in turn contains 1 dropdown lists and 3 text boxes. My problem is that after partial postback text boxes and dropdown list are found but text property of text boxes is showing empty and dropdown list's selected value is set to the first record in that box. I have also stored entire table in session and retrieve it in(!isPostBack) condition at page_load event.
part of my .aspx page is as below
[code]....
I want to add one row on every addRowTbn click event there by retaining previous rows.

I have a very simple form that contains a FormView Control Bound with a SqlDataSource, The DefaultMode of the FormView control is "Insert". I noticed that when I run the page for the first time, the databinsing and databound events of the FormView Control occurs after the PreRender Event of the page ! I know very well the life cycle of a page, but I dont know when the data binding occurs in the life cycle of a page and if it can differ from a control to another.
Is there an article or a tutorial explaining all those things.

I have a main formview which contains another formview. In the second formview I have a section that needs to insert/update. I want to access this formviews events for example I can access the main formviews item inserted event in the code behind:
FVInvoiceHCPAgreement_ItemInserted
I can't choose the nested formview events in the code behind
ie. FVInvoicePaymentInfo_ItemInserted
I have tried adding the ItemInserted event in the .aspx page
i.e. onItemInserted = "FVInvoicePaymentInfo_ItemInserted"
but for the handles clause it can't see FVInvoicePaymentInfo.

Is there a way I ignore all gridviews events (sorting, paginating) when using the back command (history.back)?
For example:
The user is sorting my grid and when he presses the back button or a link with history.back he goes to the previous page, not the previous grid state.
Im not using ajax or update panel, Im not allowed to. It's a regular grid in an aspx.

I have a master page which includes a search textbox and a button which posts back to another page. The controls are defined as follows:
<asp:TextBox
ID="SearchTextBox"
runat="server"
style="margin-left:
0px"
Width="170px" />
<cc1:TextBoxWatermarkExtender
ID="SearchTextBox_TextBoxWatermarkExtender"
runat="server"
Enabled="True"
TargetControlID="SearchTextBox"
WatermarkCssClass="watermark"
WatermarkText="Search Name" />
<asp:Button
ID="SearchButton"
runat="server"
Text="Search"
PostBackUrl="~/SearchPage.aspx"/>
The problem is that for any other TextBox on the page which is using this MasterPage, for example the login page, if you type your user name and password and hit Enter, The page is redirected to the SearchPage. If you click on login buttton everything works fine. How do I make sure hitting enter on the page in any other text box does not post back to SearchPage.aspx?

Being new to ASP.NET I have run into trouble building my own Whack-a-mole program. I think my problem comes from using Buttons, which by themselves send post backs to the server, making the software unusable. The looks are in place, making new buttons show up in the grid, in different places by random. However, when a button is pushed - the score doesn't change (which I feel is strange).
Not so strange is that the Button doesn't work since it sends post back to the server - reloading the UpdatePanel. I think I should use a different controller like the CheckBox and style it hard using CSS (which isn't a problem). Is this the correct way to go, or should I make use of JavaScript AJAX instead?
Note to self: This technique shouldn't be used in a public application since it put too much unwanted pressure on the web server.

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

Time for my daily ASP.NET question.
One of my pages shows all of our customer information from a customer table. I want the user to choose whether to see all customer records, or select a specific record from a list. So, my webpage has two radio buttons (show all customers, show specific customer), a listbox (full of customer names), and a formview control. The problem I'm having is getting the formview to update when I change modes via radio buttons or listbox selection (see code below).

I have 3 drop downs in a details view (populated from a gridview) during insert mode.
Dropdown 1
Dropdown 2 --> Based on drop down one
Dropdown 3 --> Based on drop down two
I am curious of how to handle the autopostback to update 2 and 3 since they are part of the detailsview, there isn't a selected_index_changed event.
I am ok with adding items to them on page load, just not for cascading of them...

I have three identical procedures that are all used to open the contents of a GridView into Excel. One was working fine but the other two were getting a 'RegisterForEventValidation can only be called during Render();' error when attempting to run the form.RenderControl(html) command. The only difference I saw was that the one that was working had the allowsorting value set to 'False' where the other two were set to 'True'. I set the other two to false and they worked. So what is going on here? Why would this cause the error; is the GridView somehow doing a post back and loosing settings when this value is set?

This is what I have implemented, for further code, how to send the text of the text box to the server to store in variable or database without post back? It can be done by using Ajax and update plane, but I would like to implement it using a JavaScript script.
<div id="CommentID" style=" width:30%; height:30%">
<asp:Button ID="Button1" runat="server"
Text="Comment"
OnClientClick="visibleDiv('id1'); return false;" />
<div id="id1" runat="server" style="visibility: hidden; background-color:Green; width:100%; height:100%">
<asp:TextBox ID="TextBox1" runat="server"
AutoCompleteType="Disabled" Rows="3"
TextMode="MultiLine" Width="98%">
</asp:TextBox>
<asp:Button ID="Button2" runat="server"
Text="Post"
onclick="Button2_Click" />
<asp:Button ID="Button3" runat="server"
Text="Cancel"
OnClientClick="visibleDiv('id1'); return false;" />
</div>
</div>
