AFAIK, .NET does not give this specific error message: "u cant forcefully change the date to datetime". If you want people to help you, give us the precise error message that you got.

Solution 2

first fix datetime format of your textbox.
Then use this

System.Globalization.DateTimeFormatInfo dateInfo = new System.Globalization.DateTimeFormatInfo();
dateInfo.ShortDatePattern = "dd/MM/yyyy";//This may depend on your format
cm.Parameters.Add("@fromdate", SqlDbType.DateTime).Value = Convert.ToDateTime(txtfromdate.Text, dateInfo);

Can you give the exact error message instead of just telling its not working. The code makes sense from our point of view.

walterhevedeich 25-Jul-11 5:22am

Makes sense as well. Countered.

Solution 3

You need to use SqlDbType.DateTime as your parameter if you are going to pass a DateTime value.
cm.Parameters.Add("@fromdate", SqlDbType.DateTime)

The second way to fix this could be to try Convert.ToDateTime(txtfromdate.Text).Date.
Just pass in the Date value instead of DateTime.

Thanks. A heavy weight voter downvoted me. I wish they had at least left a valid reason. Thanks for the counter.

I can see that. Too bad my vote wasn't able to compensate.

Solution 1

It seems you missed to add Value on your code. Try this.

cm.Parameters.Add("@fromdate", SqlDbType.Date).Value = Convert.ToDateTime(txtfromdate.Text);

The OP seems to have marked this as answered.
However, I felt this would not be the cause of the error.

The Value property is taken by default right?

walterhevedeich 25-Jul-11 5:33am

I agree this was not the real cause of the error. I just pointed out what he needs to add but it seems will still get the error that he gave a while ago, since the type I gave is still SqlDbType.Date. I was assuming he was getting multiple errors. Perhaps a combination of our answers might solve his problem? :)

Yes. Helping the OP solve errors is the final motive so hope these solutions helped him in the end.
