Datagrid cell's Numeric Validation in c# -


I want to validate a separate cell in the datagram. If I want only numbers in a particular cell in the datagram, how can I do it? For example:

im using Datagrid View. I want to validate this phone number area with 3 columns, datagrid ID, name, phone number. If a user enters some other value from a number then I want to give an error message.

This can be an easy task as it is very new to C #. Please help me with this problem.

Thank you all

Do you have a public boot valid phone (string phone Number) method? If so, drag an error provider control into your form, if so, you can call that method in the text_changed event of the phone number field. If this happens - ( phononumber = phononumbertaxbox. Text;

if (valid phone (phone number) == incorrect) {errorProvider.SetError (phone number text box, "please call a valid phone Enter the number ");} If (valid phone (phone number) == true) {errorProvider.SetError (phone number number," ");}

You can also call it on validity event I believe that this allows the user to leave the field, this is a better way if it is a web app desk For top, use the text_changed event.

If all the form fields are related to an object, then you can also add errors through data-packing, but I do not have enough detail for clarification on this I applied it, but the object and verification was written for me, I bowed it over the form, it really works, an error projector and my receipt Drags the database for each object, then set the data source of each and every field in the object. The error information is automatically in the Form_load event with a line of code: 

  Binding object. Datasource = Inserted Object;

sql - dynamically varied number of conditions in the 'where' statement using LINQ -

I am using my first project LINQ (in mvc), so maybe there's something very simple that I remember. However, a day of searching and experimenting does not work, so it works. I am trying to write a LINQ query (Linux to SQL) in which in many cases where the statement is different from an OR or an AND. We do not know how many conditions are going in the query till runtime. This search is for filter control, where the user can choose multiple criteria for filtering. Select from table where table.col = 1 or table.col = 2 or table.col = 7 .... 'Other number of conditions Before I just create the SQL query as a string, while looping over all the situations. However, it seems that there should be a good way to do this in LINQ. I tried to use Expression trees, but they had a second thought for this moment on my head, where the lambda function was to be executed inside the statement such as: values ​​for matchingRows = matchingRows for each value Where (function (row) row.c...

asp.net mvc - Dynamically Generated Ajax.BeginForm -

I have a problem with ASP.NET MVC Ajax forms. I generate many Ajax form in a table such as: & Lt; Input type = "submit" name = "activity" value = "add activity" / & gt; & Lt;%}% & gt; & Lt; / TD & gt; & Lt; / TR & gt; & Lt;%}% & gt; So far so good. When I post one of those forms, it gives a partial view in a div, and in this new partial view a new Ajax Beginnform (which is not in Genesis form) This second Ajax Beginnorf is exactly like the ones I got on the table, but when I post it, I do not get the "Ajax Post", but a normal post that sends me to a new page, I do not know whether the two Ajax forms What is the reason for the difference between, why is it the "dynamically generated" Ajax form behaves like a normal HTML form? By the way, I know that I can do it in different ways using javascript, but I would like to understand whether it can only be done using MVC helplars and Ajax lib...
