Validating gridview jeremy jackson dating
It may be set to one of the following values: In R2 2016, Telerik introduced the Validation Type property of Rad Grid View. This results in a binding validation error (Figure 3) and the Grid View Bound Column Base editor will enter into an invalid state.
It provides you with the possibility to choose what type of validation to apply for each instance of Rad Grid View. In the previous examples, the data was validated per cell, using the Cell Validating event or property validation.
Hi, I have Rad Grid View object and I want to Validate user input. when the user enters a value which is greater than 0 for column1 then if the column2 is greater than 0 an error must be occured and also this is the rule for coulmn2 (that is if coulmn2 value is greater than 0 and also column1's value is greater than 0 the error occurs.) the problem is that first of all I must check the value of a cell.
but when I check an error occurs and tells that the value is null: if(column1.currentrow.column["My Coulmn"].value! event fired whenever the current row changed, not just only when editing only. Look like the Value Changing event is triggered while in editing. This is not needed in my case where I want to validate the new value when user pressed the Enter key. The Cell Validating event fires whenever user clicks on a row, not just in edit mode. Maybe because it could host other type of controls?
We are going through the following C# code to analyze the process of validating data in grid cell.
The C# code snippet will enable the data cell validation in a textbox column for entering only none empty strings, which will disable the data validation and display the error indicator at the row header.

The mark up would look something like this: Noticed that I've added a templatefield column so that we can add the radio button there.Also I have set up some Bound Field columns and set the Data Fields as Row Number, Col1 and Col2.The purpose of this tutorial is to show you how to validate data using Rad Grid View. An alternative approach is to use validation on a property level as shown in Example 4.Rad Grid View exposes a property - Validates On Data Errors - that controls the way the data validation, provided by IData Error Info and INotify Data Error Info Interfaces, is performed. Length When you try to enter an order number that has fewer than five characters, you should see a validation message that is similar to the one in Figure 2. Is Valid property to False, this will cancel the editing process and will return focus to the invalid Grid View Cell. In this case, you need to throw an exception when an incorrect value is about to be set.
