View 13 RepliesI have a formview which binds to a table where one of the fields is an integer zip-code field. I want to pad the zip with a leading zero in the edit template when the zip is something like "02134". How do I edit the bound data without "breaking" the two-way binding?
I wrote simple function to add the zero and return a string:
Public
Function padZIP(ByVal zip
As
Integer)
As
String
Dim tmpStr
As
String =
CType(zip,
String)
If tmpStr.Length = 4
Then tmpStr =
"0" & tmpStr
Return tmpStr
End
Function
and I can call it in the itemtemplate fine:
<asp:Label
ID="ZipLabel"
runat="server"
Text='<%# padZIP(container.dataitem("Zip")) %>'
Width="30"
/>
but, trying to do that in the edititemtemplate breaks the binding?

I have a gridview and it has two ItemTemplates for editing, which replace a label with a dropdownlist. The dropdownlists are databound in the RowDataBound function as shown below. It works just fine except for rows which are in the Alternate rows (as defined by the auto format selection.) In essence, the ItemTemplate is replaced by the EditItemTemplate properly bound; but the AlternatingItemTemplate is replaced by empty dropdownlists. Is this a known feature? Is there a workaround?

I am handling the row databound event. I need to bind a dropdownlist which is present only in the EditItemTemplate.
So it is throwing:
DropDownList ddlAccountingPeriod = e.Row.FindControl("ddlAccountingPeriod") as DropDownList;
UIControlHelper.BindApprovalPeriod(ddlAccountingPeriod);
this throws a null exception as the dropdown is not present in the ItemTemplate.
Is there a way to check whether it is itemtemplate or edititemtemplate.

I have a gridview which uses an EditItemTemplate and an ItemTemplate for an 'Effect' column. The ItemTemplate simply displays the bound data using a label control. The EditItemTemplate defines a databound DropDownlist control which contains all the possible selections.
The gridview also contains a bound 'State' column which gives the State of each row. I have already been able to access this field in the gridview_RowDataBound event, so far using the value to decide whether to re-colour a row or not. What I would like to do is use this value to determine whether to use the ItemTemplate or the EditItemTemplate for each row.
Effectively I want to be able to decide whether to display just the data (For an Approved row) or display the DropDownList and allow the user to make updates (For an In Work row). I have searched for information on this issue online but have not found a lot, so I presume that my approach is not possible.

ths is my html code here i am editing the gridview data on the edititemtemplate itself but it shows error when i am going to get the testiActive .And also the when i delete it shows the object Reference exception. i do no what the issue the same thing i used on the updating - there i got the id value - when i am going to delete it show error ther.

I have one more time a problem with a DetailsView..I would like to fill a TextBox (or Label) with a function in my DetailsView and on the Update getting value contained in this control.

I have a "simple" gridview that has some columns, and the ability for editing/deleting. I recently found that I can change the editing textbox to a dropdownlist and have follow that, using:
[Code]....
It's quite simple and instead of using an sqldatasource, I have successfully implemented using the sqlclient in the codebehind to bind data only when I want (since this GridView is for "reports" and is queried by many parameters from user inputs).From what I've found online, the only way people have populated the dropdownlist is by using an sqldatasource - is there any way to populate it using the codebehind sqlclient like I have for binding the gridview and other dropdowns on the page that are exactly the same actually. I'd obviously have to set the SelectedValue to be what the value is coming from the database, which I can't see being that difficult.
The tough part seems to be knowing when to access this "MoneyTypeEdit" dropdownlist. I thought it would be in the RowEditing event, so I tried something like:
[Code]....
And I know everything outside of the "inserted code" works, because it was fine before I added that, but the dropdown obviously didn't have any values. And I know the code inside the "inserted code" works because I use it somewhere else on my page to populate a similar dropdown. But I get the error that MoneyTypeEdit is null, and I'm guessing it's because it can't find the "MoneyTypeEdit" dropdownlist.
how to use validation controls with item template(not editItemtemplate). I want to display text boxes irrespective of mode so i am using textbox inside itemtemplate.There is a save button which will be clicked after entering prices for all the rows.
I have a grid with two columns. In one column the user can enter the price and for that i use textboxes inside ItemTemplate. So there is not editmode here.It will always in the edit mode, I meant the user can enter values always.After entering values user can click on Save button and on this i need to validate the values, i meant the prices the user entered. I tried using validator controls inside ItemTemplate column but it is not working.

How to write code in vb.net to control the Dropdown which is inside FormView EditItemTemplate. FormView named "frmFaultsReg" DetailsView named "lstStatus" Actually what i want to do that there is a textbox inside FormView EditItemTemplate and ItemTemplate to insert Closing date. lstStatus has a value PENDING and CLOSED. If a user select CLOSED from lstStatus then the date textbox named "ClrDateTimeTextBox" should show current date time and to insert into database and if user again selects PENDING from lstStatus then the date textbox should show empty. I think the postback of lstStatus should work but lstStatus is inside the FormView thats why I am unable to hook it.

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.
I have an ObjectDataSource with a number of parameters. These parameters are binded in my FormView EditItemTemplate and the ItemTemplate. My Stored Procedure column names in my ItemTemplate are different to the Bind properties used in the EditItemTemplate. This is obviously throwing an exception when I update a record.
Instead of using Bind("Columne Name") in my EditItemTemplate how do I use a ControlParameter to reference a TextBox in the EditItemTemplate?
I may be wrong but I'm trying to use the PropertyName=Controls but i do not know how to reference the Textbox in the EditItemTemplate.

I have DataList control and I want to assign to it's edititemtemplate some User Control. The problem is I can't find when I should databound UserControl to data, as my UserControl doesn't have static look (it renders different depending on some property values and datasource).
I was try to simply set my user control in edititemtemplate
<EditItemTemplate>
<uc:MyUserControl id="myUserControl1" runat="server" />
</EditItemTemplate>
and then bind it to data in ItemDataBound event handler, but it remains empty
if(e.Item.ItemType == ListItemType.EditItem)
{
var p = (Pair)DataBinder.GetPropertyValue(e.Item.DataItem, "Key");
((AnnouncementUserControl) e.Item.FindControl("userControl1")).RepeaterDataSource =
_templateWorker.ReturnTemplateByAnnouncementId(Convert.ToInt32(p.First), true);
}
how can I databound my control, or another approach which will make me avoid this problem?
