I am developing web application using csharp on visual studio 2008. I am loading the data from Microsoft Excel to datagrid. But when I want to check the date in a given column and getting the error
String was not recognized as a valid DateTime . How can I solve this problem? The code I am using is below.
[Code]....
DateTime dt = Convert.ToDateTime(txtldate.Text.Trim());
DateTime dt1= Convert.ToDateTime(dt.ToShortDateString());
// txtlday.Text = dt1.DayOfWeek.ToString();
I have an SqlDataSource with several parameters, one of which is a date/time, that is in the database it is stored in one field as short date + long time, i.e., "11/14/2010 9:15:34 PM".
I pass a string to that parameter which looks exactly like that, but I get an error: "String was not recognized as a valid DateTime?"
I am having trouble formatting the date on a textbox I get the error above if I don't enter the date in MM/DD/YY format in the textbox. I am also using this in a FormView so I can't format it or don't know how to in the code behind so if there is a way to format it in design view that would be preferable. Does anyone have any ideas on how I would do any of this.
<asp:TextBox Text='<%# Bind("BIRTH_DATE", "{0:d}") %>' Font-Names="Tahoma"
Font-Size="X-Small" ToolTip="MM/DD/YYYY" ID="txtBirthDate" runat="server"
TabIndex="2" CssClass="style5"></asp:TextBox>
I want to filter a Gridview by date. I enter the date in a textbox and use FilterExpressions. I keep getting the error message: String was not recognized as a valid DateTime. How can I solve this?
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
<cc1:MaskedEditExtender ID="MaskedEditExtender1" runat="server" Mask="9999/99/99 99:99:99" MaskType="DateTime"
TargetControlID="TextBox1" PromptCharacter="_"> </cc1:MaskedEditExtender>
<cc1:MaskedEditValidator ID="MaskedEditValidator1" runat="server" ControlExtender="MaskedEditExtender1"
ControlToValidate="TextBox1" EmptyValueMessage="Date is required" InvalidValueMessage="Date is invalid"
IsValidEmpty="False" TooltipMessage="Input a Date"></cc1:MaskedEditValidator>
<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="xxx"
SelectCommand="SELECT * FROM [xx]"
FilterExpression="Date <=#{0}%#">
<FilterParameters>
<asp:ControlParameter ControlID="TextBox1" Name="Date" PropertyName="Text" Type="DateTime" />
</FilterParameters>
</asp:SqlDataSource>
I am extracting some value from my database table. there is a files haiving datatype dattime. in some recordsthis column has null value, by default.
see my code
lblDonorname.Text = dt.Rows[0]["SubContarctor_Name"].ToString();
string dtrequest = dt.Rows[0]["Request_Date"].ToString();
if (dtrequest.ToString()!="")
{
DateTime dtrequest1 = Convert.ToDateTime(dt.Rows[0]["Request_Date"].ToString());
lblRequestDate.Text = dtrequest1.ToString("dd/MM/yyyy");
}
lblSubConAmount.Text = dt.Rows[0]["Sub_ContractAmt"].ToString();
bolded part for extracting date in a label( lblRequestDate). is it ok by point of view security (I never get an error although the data may be complex)
I am very new to ASP .NET and am getting above error when trying to insert a new record into a SQL database. I have turned on Option Explicit On so the default date of 01/01/1900 does not get assigned to this field automatically. Since most of the people in the database will not have a date of death, I need to have "blank" deathDate. When I run the stored procedure within SQL and choose pass null value, the Insert Procedure works fine. When I attach to Web Form, however, I get String was not recognized as a valid DateTime error. How can I set it so Null values are accepted into this date field.

bolded part for extracting date in a label( lblRequestDate). but for some records it is not working and for some it is working. I want to make it like if any record doesnt have any value then it should shows in label
lblRequestDate blank
how to do that, even I am not understanding if it work for some records then it should work for all records where as all records having NULL value.
This worked before but NOW it is not working. Really weired.

String WCRDate = txt_Date.Text;
String WCRTime = DDL_Hour.SelectedValue + ":" + DDL_Min;
DateTime WCRDateTime = new DateTime();
WCRDateTime = DateTime.ParseExact( WCRDate + " " + WCRTime , "dd/MM/yyyy hh:mm" , new CultureInfo("en-GB",true));
the txt_Date.text field gets the date from an asp calendar in the format 21/07/2010
