Forms Data Controls :: Way To Set Default Values On The Controls
May 27, 2010
I have a gridview and a details view bound to an sql datasource that I am using to insert (detailsview) update and delete (gridview) records on a database. When the database table is empty and the gridview or detailsview binds to the sqldatasource the controls do not show up as there is no data to bind to. Is there any way of setting default values on the controls so that it will show when the table is empty and i can start making inserts to an empty table?
I have a DeatilsViews bound to an ObjectDataSource, I need set some default values for Insert and Update mode, which event(s) on which control(s) will be best to handle this?
I tried to set the default values using TextBoxes inside InsertTemplate, but the values are not saved to DB because 2 way bindings are lost.
have a form where I insert record via DetailView control. I have some string fields. For each string field (nvarchar in sql) I have defined the Default Value in the SQL SERVER (2008) as ''. Also I have added to each InsertParameter of the DetailsView a DefaultValue="".Yet still, if the user enters no value for one of the string fields, NULL is inserted into the table.
I have a gridview which I use to add items through the footer and the EmptyDataTemplate. There is a date field. I want to set the default of it to the current system date.
i have a check box list control that is used for showing related files to some post.
what i want to do is set the databound items "checked" to true by default
then,
if a user unchecks some item and clicks the save button. then the selectedindexchanged will fire and i will do some logic.
what i have done is.
--Set All Databound items to "checked" --
[code]....
in the end i want the item that was unchecked to be removed (all other items will remain checked). but even before that, when the user control is loaded all the files that were bounded are being deleted by the index change event.
I have some (probably very basic) questions about developing custom controls. I am wanting to derive a set of button controls, and the first one I have started on is a "DeleteButton", that has a additional property (DeleteConfirmationText) that is built into the OnClientClick attribute. To get that added, I overrode the Render method as follows:
[Code]....
This all works well. Now, I will add some logic to make sure that there is some text in the DeleteConfirmationText property, but that isn't the intent of my question. What I am also wanting to do is to override some of the default property values, so I added that to the default constructor:
[Code]....
Now, in the designer in VS2008, and I look at the properties for the control, there isn't a default value shown in the "Properties" section, and the Causesvalidation still shows the underlying classes default value of "True". As well, in design mode, where the GridView control that containse my DeleteButton control would be displayed, there is an error box "There was an error rendering the control. 'Are you certain you want to delete this attorney?' cound not be set on property 'DeleteConfirmationText'. Here's the markup where I am defining the deletebutton control:
I'm trying to execute a simple insert statement with the GUID and timestamp populated by default from the server. I have both of their default values set as (newid()) and (getutcdate()) respectively in SQL server. However, I receive the error when I try and execute the command "Insert Error: column name or number of supplied values does not match table definition". How do I construct my sql insert so my id and timestamp columns use their default values as assigned in sql server?
am stuck in a very simple problem but couldn't find a way to get rid of it.May be I clicked somewhere in my web application that is now a cause of underline every label, cell of table or whatever typing in it.how to remove default underline,
I would rather specify fields in my code behind than embedding them in the .aspx page.
I also have a subtotal label control in my repeater that I would like to populate its text property by mutiplying two of the database values e.g productprice * unitprice shown in my repeater.
I need to do this in code behind, looping through the repeater. Any idea of how I can do this in C#?
Updates to the edited item are not passing the new / updated values but rather the original values. And I can't for the life of me figure out why when I change the original value in an edit textbox and post the update the new value is not being passed. I get the original value. Perhaps fresh eyes can spot the problem. This should be super basic but apparently I'm missing something.
Here's the code for the Item and Edit templates. The code behind is below this.
i take data from Sqlserver database , and my prblem is that i want to get old and new values from gridview and base on that i want to change there background colors .. i try gridview rowupdating , editing ,updated Events but when i debug no break point hit and there was no value in ViewSate that i declare ,
I have a grid view and I added edit and Save buttons to it. When I click on edit I am able to edit the data but when I click on save I amgetting the data before edit.Please see my code below.Eg: I have start date as 2005-10-10 12:00 AM so After I click On edit it is letting me to edit, So If I edit the start date to 2010-10-10 12:00 PM and click on the save button I am stil getting the old start date. which is 2005-10-10 12:00 AM instead of 2010-10-10 12:00 PM
I am trying to use a <asp:ListView> control on an aspx page. The problem I am having is that a large margin appears on the rendered page. It is there by default - I didnt specify it. Does anyone know how to get rid of it ? I've tried specifying every CSS item I can think of but have had no luck.
I am using asp.net/c# application. In my application, I have a gridview.<asp:GridView id ="gv_QuestionList" runat="server"> </asp:GridView>In Code Behind, I created dynamic textboxes and DropDownLists on RowDataBound.
[Code]....
I have a Save button out side the gridview which stores all the row values into database. when I click the "Save" button, I lost dyanamically ceated controls like textbox,dropdown and values (on postback).How can i get all the dynamically created controls and values after the post back?
I am using DetailsView to INSERT new records. I have a field "Paid Date"(date) that needs to be pre-populated with the current date. 90% of the time, the user will use the default date, however, there are times when the user will need to change the data as needed. I want to add this default in the code-behind. I DO NOT want to use template item.
what i have a is a dropdownlist and what i have done is set the datasource to be "select top 10 * from Orders"I have only displayed the OrderID , CustomerID and the Freight i would like to display in a dropdownlist. But what is happening is that for all 10 rows the dame value in the dropdownlist is shown. The dataset that is bound to the dropdownlist initially is all that items in the database.i would like the freight for that particualar Orderid to be displayed even if it is lets say item number 5 in the dropdownlist or itemn number 2 .
The intension is to get the all text file names in the drop down present in a particular location. When a user selects any filename from the drop down, it will show the data which is in that particular text file in a GridView.
I've done both the steps and it's almost complete but i stuck on a small issue. Probably because of non-usage of ASP.NET for a long period of time. The problem is, the drop down only selects the default value not other values.Here's my code for DropDown Selected Index Change
protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e) { DirectoryInfo di = new DirectoryInfo(@"C:myLogs");
I need my gridview to display no records when the user first lands on the page. Right now it's showing all records by default based on a query I've defined in a Table Adapter in my dataset.
I have 2 web controls that the user employs to filter data (or view all records). They are working fine--I just need to have the gridview show nothing by default.
There are few columns in Gridview control , i want them to be sorted according to the column which i have specified . .how to specify that . .code is shown below . .By default i want them to be sorted according to "ENTRYDATE" . .
i have a gridview in one form showempdetails.aspx and another form is to edit the value of selected row editempdetails.aspx in this page i have textboxes and dropdowns.
im using querystring which is bringing empid
(eg: empid=1 should bind all other columns to my controls of editempdetails.aspx)
below code is of empedit.aspx this takes loginid to employees_add.aspx
[Code]....
here by using primary key i should pass all my values of previous selected corresponding values into my textboxes.
