I'm 100% sure this is going to be something really simple but I'm using a dataset to update a table which works fine until I ask it to update using data from a textbox.
So this won't work:
Dim updateCMS As New AdminCMSTableAdapters.AT_CMSTableAdapter
updateCMS.Update("Home", "Home", txtHome.Text, 1)
But this will:
Dim updateCMS As New AdminCMSTableAdapters.AT_CMSTableAdapter
updateCMS.Update("Home", "Home", "Test", 1)

View 3 RepliesI'm trying to create a ShoutBox for my site, and for those of you who are not familiar with shoutboxes, they are chat boxes on websites that users can post live messages on, and the other uses will see their message and be able to respond. I didn't find any good ones online, so I started to write my own. I'm doing it with an XML, but I want the user to be able to post messages using a textbox I added (txtMessage) and the button (cmdPostMessage), which should add a new item to the XML file, and all the other uses will receive that message (their xmlDataSource and the DataList will PostBack every second or something like that). It is able to read messages, but not send.I am however facing three problems:
1- I need to find a way for the user's input to be added to the XML.
2- I need to find a way for the current logged-in username to be found, and added to the XML, and also detect if no user is logged in, in which case the user wil receive an alert saying "Please log in to post messages to the ShoutBox" and redirect them to the login page.
Here is the text in the XML

I have a TextBox in a nested FormView that I want to use for entering a date. I have added a calender extender to the TextBox and I want to set TextBox to read only so that the date can only be entered by using the calender extender. This way I can avoid improper date formats.
The problem is that when I enter a new date and click the Update button, the new date is not saved to the database. I have done some searching on the WEB for a solution, and I found that "Page.Form.SubmitDisabledControls = True" is used in the Page_Load event to solve this problem. I have tried this and it does not work.
Another solution that I have seen is to set the control to readonly at runtime in the FormView "ItemCreated" event. I have been unable to access the "ItemCreated" for this FormView because it is nested.
I have a bound field in a DetailsView that I want updated with the contents of TextBox2.Text when I update. I have TextBox2 set AutoPostBack True. Cannot remember how to move the contents on update. I tried converting the "Description_Update" to a template field without success.
I can copy and paste the contents of TextBox2 into the DetailsView and it does update as do the other DataFields.
<asp:TextBox
ID="TextBox2"
runat="server"
Height="80px"
TextMode="MultiLine" Width="360px"
Font-Size="Small"
MaxLength="120"
Text=""
Font-Names="Calibri" AutoPostBack="True"></asp:TextBox>
<asp:BoundField
DataField="Description_Update"
HeaderText="Descrip"
SortExpression="Description_Update"
/>
Do I need to use adn Eval or DataBind function or both. I have triued several combinations and do nothing but continue to butcher the database tables.
I've been searching for a tutorial or example on how to update my database when I change the text in the textbox that is in a DataList?

I have a gridview with a date field. I don't want the user to be able to type in their own date and mess up the format so I made the property readonly. That date is then set by a point and click interface. This is all working fine but when the user clicks update this field doesn't update because it's readonly. If i turn readonly off it works so is there a way to turn off the readonly property right before submit?

I have an update panel and data list. Data for this fields are loaded from database (to the textbox).
The save button should write data to database, unfortunetly it dosen't. Instead are loaded empty data. I think The reason is that the textboxes are inside updatepanel.

View 1 RepliesIn ASP.NET I have a dropdown with some items in it, I have a button and a textbox. I am subscribed to the SelectedIndexChanged event of the dropdown where I pass the new selected index of the dropdown to a struct that converts it's index (via enum) to a string. That string is then gotten through a property in a class to put into the textbox.
[Code]....
Now the problem I have is that, when you click it (the button) the first time, the action get's updated with the current action selected in the listbox, but then when you click the button again WITHOUT changing anything in the listbox, the textbox shows the zero'th item in the textbox, (seems to reset), although it actually hasn't changed at all.
I'm guessing this might have something to do with the postback caused by the button click, which resets the state of the global or something, but I'm not sure. Why is it being reset while the dropdown box is still as I set it the first time?

i have a Textbox and a few update panels. But each time the update panel clicks, then the focus on the textbox is gone So for example, we all know that when a user clicks on a textbox, there will be a blinking | symbol. But each time my panel updates, the focus on the textbox goes. Does anyone know how i could keep the focus on? as in, each time there is an update, still keep that textbox | symbol blinking.
