I am using the following Codes to get the date from the date picker
objDD_ml.EffDate=(DirectCast(drv.Cells(3).FindControl("rdpEffDate"), RadDatePicker).DateInput).ToString
But it does not return the date... It returns like 'DateInput'
How can i use the code to get the value for Effdate as a correct format of date
Anyone please help me..
Whenever you want date into string and in specific format you can always apply following :
objDD_ml.EffDate = (
DirectCast(drv.Cells(3).FindControl("rdpEffDate"), RadDatePicker).DateInput
).ToString("dd/MM/yyyy")
Try to cast the FindControl object into the corresponding ASP control externally. Then access the value of that control and convert it to .ToString
I don't know what control you are using, but it should be something like below -
objDD_ml.EffDate = ((RadDatePicker)(drv.Cells[i].FindControl("rdpEffDate")).SelectedDate.Tostring;

I am converting a string that is being read from a textbox in gridview
int numTC = Convert.ToInt32(((TextBox)row.FindControl("numTC")).Text);
However it is returning the following exception:
Input string was not in a correct format.
Can anyone see anything wrong in the conversion?
Thanks
Make Sure that your gridview can accept only numbers you can have a filterextender using ajax and I m sure u will do that what else you can do is to check whether you have a textbox is null or not using the Function given below
if(string.IsNullOrEmpty(((TextBox)Row.FindControl("numTC")).Text))
{}
((TextBox)GridViewname.Rows[e.RowIndex].FindControl("numTC")).Text;
and
use this extender or u can use javascript as well
If it is going inside the if statement that means the value is null
if(!string.IsNullOrEmpty(((TextBox)row.FindControl("numTC")).Text)) {}
I have used ! sign now it will go inside the if statement if there is some value in it.
and try to convert this text into integer using try catch block if u get any exception you can take whatever action you want to.
Let me know if it is complete
It is obvious that the value of the returned in the "Text" property of the text box cannot be converted to inter, I guess you have to insure first that you are returning the correct textbox and that it contains a valid value before attempting the conversion.
I have written code for two checkboxes:
string sdate= Convert.ToDateTime(txtFromDate.Value);
string edate=Convert.ToDateTime(txtEndDate.Value);
I am getting the following error: "String was not recognized as a valid DateTime".
Well, it's reasonably clear: the input string wasn't in an appropriate format. I suggest that instead of using Convert.ToDateTime, you use DateTime.TryParseExact and specify the format string (or strings) that you expect the user to enter.
Using TryParseExact instead of just ParseExact means you can detect if the user has entered an incorrect date without an exception being thrown - and you should check for that. Basically the return value of TryParseExact indicates success or failure, and an out parameter is used to capture the parsed date/time on success.
What I hadn't noticed to start with is that you're then trying to assign a DateTime value to a string. That's not going to work - but we can't advise you on what you should be doing instead without knowing what you want to do with the data. I suspect you want to change sdate and edate to be DateTime variables instead.
I had Ajax calendar and when I selected from it it give me date as (07/12/2010)
and when I made space between the year and / it converted to (2010/07/12) and this invalid date so pleas what the error.
That's not a error is it? It sounds to me like the Ajax is just setting the date as a culture invariant. See this article on CodeProject
Try Specifying the date Format by using calendar Format property to "dd/MM/yyyy"

If you are working from JS you would be better off working from its numeric (epoch) representation and then convert it to whatever format you want to use or use the js date api to achieve what you want.

Is there some way in flex to parse strings to date. I want it to support custom formats similar to 'dateformatter'. Using 'dateformatter' class we can parse date object in various string formats as specified by 'formatString property'. I want it other way round, from string to date. The parse method 'Date.parse(my_string)' does string parsing but for a very limited set of formats. Can't we have something similar to following, where user can specify his/her own formats.
someformatter.formatString = 'HH::MM::SS' ;
mydate = someformatter.formatTodate('23::56:34');
Will 'parseDateString' method of dateformatter be useul here?
Thanks in advance.
You can use
DateField.StringToDate()
This is static function of DateField class, and returns Date object.
i have a project for uploading video.in that when i click the showvideo button there is a error.
code-
param name="url" value='<%# "VideoHandler.ashx?FileID=" + Eval("FileID") %>'
error message ::: conversion form string="VideoHandler.ashx?FileID=" to type 'Double' is not valid
anyone knows please answer for me thank you
"VideoHandler.ashx?FileID=" is a string. Eval("FileID") results in a double. You have a type mismatch, so the addition overload doesn't know how to proceed. Solve it like this:
string.Format("VideoHandler.ashx?FileID={0}", Eval("FileID"))
Without seeing the code, it sounds like you are trying to convert a string which isn't a valid double. Are you taking the value of the query string and trying to convert it or, could you have accidentally tried to convert the page name along with the query string? Based on the short error message you gave, that is what it looks like. If you post the code which is doing the conversion, that will likely make it clearer what is going on, but that is my best guess at the moment.
You are trying to convert a string which is not a valid double type.
I think you are trying to convert the FileID field to double. Then you can split the string and then convert only the FileID part of it.
You can get the querysting data using
Request.QuerySting["FileID"] and then convert it to double.
or use
Double.TryParse Method
We should see some code. Apparantly the application is trying to convert "VideoHandler.ashx?FileID=" to a Double value which cannot be done.
Just add ToString() to the end of your Eval. FileId is a double, and it's seeing the + and trying to add it to a string, numerically, instead of concatenating it.
