Is there a property for the RadNumericTextBox equivalent to the "Validation-IsRequired" property of the RadInputManager control?

Hi,

The RadNumericTextBox does not provide this property, however you could suggest using the RadInputManager to extend regular textboxes as RadNumericTextBox and use it as needed.

Using the RadInputManager to extend regular textboxes works great, but does not offer Spin Buttons or keyboard and mouse intercept functionality.  I tried to use the RadNumbericTextBox as TargetInput control of RadInputManager, but that does not work.  Can you suggest a way I can include the "Validation-IsRequired" functionality in a TadNumericTextBox control?

Hi,

You could use the RadNumericTextBox with asp RequiredFieldValidator in order to achieve the needed functionality. Please refer to the following online demo which elaborates on this matter.

Hi Maria,

I appreciate your reply, but I am currently using ASP RequireFieldValidator now.  The feature of the RadInputManager is very neat where the warning image is displayed inside the field as soon as the user tabs out of it, instead of waiting for a postback.  This is the feature I am looking for in the RadNumericTextBox control.

Thanks,
Ed

Hi,

Note that this is the default behavior for all asp input controls not only for Telerik RadNumericTextBox and it could not be changed. It actually needs a postback only for the first time you try to validate. After that as the validator is already properly attached to the control the tabbing from the input fires validation.

Hi,

I have the same result, that's will be very great if RadInputManager also support RadNumericTextBox validation. Or is there any purpose in behind that not to support RadNumericTextBox validation?

Thanks
Herbert

Hi

I want to use RadInputManager to set the control RadNumericTextBox is required field and validate the input, the control is within RadGrid EditFormSettings.

I follow the following example, and modify a bit, is it my coding problem?

http://www.telerik.com/help/aspnet-ajax/grid-linq-to-sql-manual-crud-operations.html 

GridEditFormItem editedItem = e.Item as GridEditFormItem;
 
RadNumericTextBox rntTotalCarton = editedItem.FindControl("rntTotalCarton") as RadNumericTextBox;
RadNumericTextBox rntQuantity = editedItem.FindControl("rntQuantity") as RadNumericTextBox;
RadNumericTextBox rntUnitPrice = editedItem.FindControl("rntUnitPrice") as RadNumericTextBox;
RadNumericTextBox rntNetWeight = editedItem.FindControl("rntNetWeight") as RadNumericTextBox;
RadNumericTextBox rntGrossWeight = editedItem.FindControl("rntGrossWeight") as RadNumericTextBox;
 
inputSetting.InitializeOnClient = true;
inputSetting.Validation.IsRequired = true;
 
NumericTextBoxSetting numericTextBoxSetting = (NumericTextBoxSetting)RadInputManager1.GetSettingByBehaviorID("NumericBehavior1");
numericTextBoxSetting.TargetControls.Add(new TargetInput(rntTotalCarton.UniqueID, true));
numericTextBoxSetting.TargetControls.Add(new TargetInput(rntQuantity.UniqueID, true));
numericTextBoxSetting.TargetControls.Add(new TargetInput(rntUnitPrice.UniqueID, true));
numericTextBoxSetting.TargetControls.Add(new TargetInput(rntNetWeight.UniqueID, true));
numericTextBoxSetting.TargetControls.Add(new TargetInput(rntGrossWeight.UniqueID, true));
numericTextBoxSetting.InitializeOnClient = true;
numericTextBoxSetting.Validation.IsRequired = true;

Hello Herbert,

Please note that the RadInputManager control is designed to inputify only regular asp TextBox controls in order to simulate RadInput controls look and feel. In your code you are adding RadNumericTextBox as TargetControls for the RadInputManager which is not a supported scenario.
As you can see from the mentioned help topic the target controls are th GridBoundColumnEditor fields which are actually asp TextBox controls.

All the best,
