Forms Data Controls :: How To Force Control Input Format In Decimal Field In GridView
Mar 6, 2010
when updating a decimal field in a GridView all is fine when using e.g. "2.3" ("." to separate the fraction!)
However, when using "2,3" I get e formatstring exception!
I tried "regularExpressionValidator/RequiredFieldvalidator" but did not succeed! Tried also with FormatString like {0:n}.....
Questions:
is this controllable by "Culture / UICulture" in web.config (played with it without success!
How do I best check for correct input i.e. force "." as separator
Can I use the "DataFormatString" property for the appropriate GridView field (like {0:n}) ......
[code]....

I'm trying to populate a detailsview according to the selected row in a gridview. How do you choose what the selectedindex is? For example my sql statement is:
SELECT [Assignment_ID], [Staff_ID], [Client_ID], [Day], [Month], [Year], [Start_Time], [Job_Type], [Billable_Time], [Travel_Time], [KM_Travelled], [NC_Time], [SP_Time], [Billed], [Description] FROM [Assignment] WHERE ([Assignment_ID] = @Assignment_ID)
and @ assignment_ID is gridview.selectedindex
but when it runs I get the error:
Input string was not in a correct format.
Description:
An unhandled exception occurred during the execution of the current web request. review the stack trace for more information about the error and where it originated in the code.

I have a GridView that records can be added to.There are only 2 fields in the table that the records come from which are date field and an integer field.The date field is fine "as is".The problem is that you can't format the integer field.I have tried every way that I can think off.The last 2 ways that I have tried have used String.Format because I am using EVal and with Eval you can supply anoptional second parameter to specify a format for the returned string.I have tried in both html and code behind , html gives an error message but the code behind (code behindthe RowDataBound method) doesn't give an error message:In the html looks like:
<ItemTemplate>
<%# Eval(("inFrmDate").ToString(), String.Format("{G}")) %>
</ItemTemplate>

I was read your post: "Export GridView to Excel in ASP.Net with Formatting using C#" and is very useful. That code works perfect. But I need create a new format for a specific column in my sheet before to export it. For example:My DataTable have a column with decimal numbers and I'm trying reduce the tenths for each number.I want this: 2,874444 ----> 2,87 for a specific range. In this case I need it for all numbers in the column 13 or well said for the Column called N in Excel. Only reduce two tenths.
I used:
xlWorkSheet.Range["N"+h,"N"+h].NumberFormat = "0.00";
And no works (h is for rows, N is the column. Into a foreach).

I have a DetailsView on the page and I have made one of the fields a TemplateField. In the EditItemTemplate and InsertItemTemplate I have a DropdownList that is databound to a table in my Sql Server database. I wanted to add an initial value to the DropdownList
namely "- select -" .
I set the AppendDataBoundItems property to true and added the initial value as a ListItem.Markup of the DropdownList
<asp:DropDownList ID="DropDownList_HP" runat="server"
AppendDataBoundItems="True" DataSourceID="SqlDataSource_HP" [code]...
This works fine for new input. The problem is however that the database already has records that were entered through a Windows Application and many of these records has a null value in this field and exceptions are thrown when I tried to open these records
and the system tried to set the SelectedValue of the DropdownList.After some more searching I found this help
http://msdn.microsoft.com/en-us/library/ms366709.aspx
So I changed the ListItem in the DropDownList markup to the following:
<asp:DropDownList ID="DropDownList_RefHospDV4" runat="server"
AppendDataBoundItems="True" DataSourceID="SqlDataSource_RefHosp" [code]...
This now solved the problem of opening a record where the value is null in the database, BUT now the RequiredFieldValidator is not validating anymore to make sure that a databound item is selected for this field and not the initial value "- select -". So basically now it is not checking anymore to see if valid input has been entered for the DropDownList and it accepts "- select -" thus it acts as if the field is not a required field anymore.
In short what is required is that I want to make sure that the user enters a valid selection in the DropDownList, but it must also cater for old records that do not have this field entered yet so that those old records can be opened in the DetailsView .Opening Old records (with null in that field):When these old records are opened in the DetailsView the DropDownlist should show "- select -" when the value in the database is null.
Saving records (old or new records):When saving the record in Insert mode or Update mode the RequiredFieldValidator should show that a valid input is not selected if the DropDownList is still on "- select -".

I have a text field that users enter information into a database (SQL Server). They are entering as little as a few sentances to multiple paragraphs. I can successfully display the data on my webpage, but the text field is not formatted very nicely. The output is all smashed together like one big paragraph. Ironically, when I also display the text as a tool tip it outputs as multiple paragraphs like it was entered. How can I format the output in the datalist to create a more readable text field? My datalist field is as follows:
<asp:Label id="WebDescriptionLabel" runat="server" Text='<%# Eval("WebDescription") %>' ForeColor="Brown" />

I'm getting "the input string was not in the specified format" on the last line of code below. The grid is based on a SqlDataSource that has a stored procedure pulling an integer for column 0.
int theUserID = 0;
string theUserFullName =
"";
theUserID = Int32.Parse(gvUserPermissions.Rows[gvUserPermissions.SelectedIndex].Cells[0].Text);

I have gridview control that has data binded by using EF. Whenever I try to sort my gridview I get this error: "Input string was not in a correct format." This error points to the following line of code: "int index = Convert.ToInt32(e.CommandArgument);"

I'm not sure what do I have to fix if I want to sort the columns.
If I bind the data manually what is the code for codebehind to allow sorting for particular columns.

I'm stumped on this one... it seems really simple, but I can't get around it. I am pulling 2 values (discount percent, discount amount) from a formview label control. I want to use these numbers in a calculation, but I can't seem to get the format correct.
I hit the error on this statement:
DiscountAmt = Convert.ToDouble(fvDiscountResults.FindControl(
"DiscountSubtotal1"
).ToString)
