Web Forms :: Create A Textbox That Accepts Only Numeric Values?
Feb 18, 2011
I need to create a textbox that accepts only numeric values. If the user presses a string in the textbox an alert message should be displayed.The user should not be able to type other characters Users should be displayed a instant message when character other than numeric is pressed
I want to validate a textbox that only a numeric currency value can be put into it, for example 0.00. I thought the following code was correct but it doesnt seem to wrk, its causing an error on my page and when I remove it the page is fine, it doesn't actually give exact details of the error on the page just says "syntax error" in the browser that is all.
I want to validate in server side, Suppose I have entered first numeric and another chars,I don't want to allow first numeric then how to validate in server sideĀ
For efficiency's sake I've created a number of stored procedures to run against an SQL table. Which procedure runs depends upon the checkboxlist choices a user makes before clicking a button. The checkboxlist looks something like this:
What I can't figure out is how to loop through the checkboxes in the Button1_Click event in the .cs code behind page to add up the values of the selected items. (The value of an unclicked box being 0.) Converted to a string, the totaled value is then appended to a stored procedure name (MyPROC) for entry into the SQL statement. In other words, if the user clicks just Item 1, then the Button1_Click event would produce a stored procedure name of MyPROC1, insert it into the statement, and fire off the query; if Item 1 and Item 3 are selected, then MyPROC101 would be called.
My second question is: how do I place the concatenated string into the SQL statement?
This might all seem a bit unorthodox, but given the number of variables going into statement, it seems to this newbie the best approach.
i am using one text box to enter phone number,bt here is some problem. if user enters other than Numeric ,the text box should show the error. how can i do that?
I'm trying to create a web page which to be used on a touchscreen monitor and need to do data input for the webpage thru on screen numeric keyboard (on the web page it self). When user touch on the numeric keyboard, find the focus of the textBox. And show the number.
I have a gridview control that has two bound fields. I want to restrict the user's to enter only numeric values in the second bound column. I went into the properties of the gridview control. Selected "Columns" and clicked on collection. The fields showed up.
I selected the field and clicked on the properties. I found DataFormatString property. can I restrict by making changes to this property?
