View 8 RepliesI would like the user to select an item from a drop down list. Next to the drop down is a textbox or label control. From the ddl selection I would like to populate the textbox or label from a database with a corresponding field from the database the dropdownlist was populated from. On selectindexchange event I can populate the textbox with the Unique id from the value, but I need to input a different field into the textbox. Can I use some sort of variable to assign the Textbox.Text = ?

In GridView (using VB) , I have project information, with Status and %Complete that the user is supposed to update. Trouble is they may change %Complete to 100%, but not change the status from Active to Complete. So, we wind up with a long list of Active tasks that are 100% Complete. How can I force an update to the Status field ? something like... If "%Complete" = "100" Else Status = "Complete" Not sure if I need to do this in VBscript or code behind or SQL or.

View 3 RepliesI am having a DOB text box. This text box also allows to enter the date and also to pick the date using ajax CalendarExtender.
I used to set the dirty message when we edit some thing in the page.
When I enter some thing on the text box and click on the cancel button, dirty message will occur.
The problem i am facing is that, in Edit mode, I used to get all the records and assign to the text box. In that scenerio, the dirty message si automatically set since the DOB gets changes.
Please find the below code.
<asp:TextBox onkeyup="SetIsDirty();" TabIndex="4" onclick="ClearErrorMessage();"Â
ID="txtEndDate" runat="server" CssClass="input-value"></asp:TextBox>
<ajax:MaskedEditExtender ID="MaskedEditExtender1" runat="server" Â TargetControlID="txtEndDate" Â Mask="99/99/9999" MaskType="Date"> Â
</ajax:MaskedEditExtender>

I have created a formview with 4 dynamic controls fields that LINQ to a database.
rentfoodutilitytotal
There's an event handle for each of the first three fields whenever a text change with following codes:
' extract textbox from both SubTotal and the modified field
tboxSubtotal = FormViewAssistance2.FindControl("totalTextBoxEdit")
tboxModifier = FormViewAssistance2.FindControl("foodTextBoxEdit")
'extract string from those textboxes
txtSubtotal = tboxSubtotal.Text
txtModifier = tboxModifier.Text
'convert text to double and add them together
Double.TryParse(txtModifier, dblModifier)
Double.TryParse(txtSubtotal, dblSubtotal)
dblSubtotal = dblSubtotal + dblModifier
'post the changes back to SubTotalTextBoxEdit
'totalTextBoxEdit
'EditorPart.ReferenceEquals("totalTextBoxEdit", dblSubtotal)
'PostBackTrigger.ReferenceEquals("SUBTOTRECTextBoxEdit", dblSubtotal)
'EditorZone.ReferenceEquals("SUBTOTRECTextBoxEdit", dblSubtotal)
I'm stuck on how to post/update totalTextBoxEdit to reflex changes in first three fields without having user clicking Update button to save the information into database. I've tried above 3 statements but none of them is working.

Ive got a list of records in a gridview (from an SQLDataSource) where a field value is set to True. I've also added a "reset" button in a template field at the start of the row in the Gridview.
What I would like to do is allow the user to click the reset button on a particular row and 'reset' the true value to 'false' (updating the source data).
How to take value of bound field of grid in a variable or in a textbox.

I want to create a web page using ASP.NET (C#, SQL queries) to keep track the login and logout time of all employees of a small store and total hours they work every day. Here are the fields in my table (employID, logintime, logouttime, totalhours). Once an employee log in, he just clicks the Login/Logout button. The program will store the current system time into the "logintime" field while leaving the "logouttime" field and the "totalhours" field empty until he clicks the button again at the end of the day. So when an employee clicks the button, I want to determine if he wants to login or logout by examing the "logouttime" field. If it's emty (NULL), I know he wants to logout. If the "logouttime" field is not empty, I know he wants to login so my progam will create a new entry for him. My question is, what is the best way to determine if he wants to login or logout? This is how I approach it:I create a SELECT query: "SELECT COUNT(*) FROM mytable WHERE logoutime IS NULL and employID = @employeeID" (this employeeID is the ID an employee uses to log in the web page). I use this "count" value to determine if the next operation is to let him logout or create a new entry. If count # 0, that means the employee needs to logout. I just need an UPDATE command to update value for logouttime field. I need another "SELECT * FROM mytable WHERE logouttime is NULL and employID= @employeeID" because my previous SELECT query returns only the count value. I will use a DataReader for the 2nd SELECT to walk through the fileds of the matched row to retrieve the value of "logintime" field for subtracting operation to get the total hours. Is there a way I can access the table to determine if the employee "logouttime" field is empty and at the same time using that open connection to retrieve his information if the "logouttime" field is empty? I hope what i'm trying to say make sense. I haven't coded it yet. Just logics at this point.
View 3 RepliesI have this working on another project I have but cannot figure out why I can't get it to work on another. I have a dropdownlist box with employee names. When an employee is selected, I display the data (address, phone, email, etc.) in a series of textboxes. User can make changes and then click on an "Update" button where I attempt to update the database with the changes using the sqldatasource. The code works without any errors, but the database does not update.
Here's the sqldatasource code (the code behind follows):

I have an email contact form that I have successfully populated the account users Username and email address into text boxes
I also use a text box and session variables to send parameters to a stored procedure and return a single row result in a form view.
The thing I am having an incredibly hard time figuring out is how to populate a single textbox with the data from any of those fields. or the whole control as a single summary.
Just for starters I am actually an IT Manager and NOT a coder so this is entirely a hack job if there ever was one...
