My page CSHTML variable for text and number work fine, but I cannot seem to get the check box value to post ( I am using bootstrap ), Razor pages, ASP.NET Core 2.2
I stripped my original model dialog down and the OnPost handler to try and isolate it
public class IndexModel : PageModel
{
public void OnGet()
{
}
[BindProperty]public bool customCheck1 { get; set; }
public void OnPostLineNumber(bool customCheck1) // I have tried both int and bool
{
string Message = $"Handler fired for {customCheck1}";
}
}
Best Regards,
Rena
.NET forums are moving to a new home on Microsoft Q&A, we encourage you to go to Microsoft Q&A for .NET for posting new questions and get involved today.
Then public void OnPostLineNumber(int id,string ATA,
bool doRemoval)
{
string Message = $"Handler fired for {id} with {ATA} and Removal Requested {
doRemoval}" ; // NOW WORKS
I am still puzzled why the 2 other variables
id, ATA- with just name attribute linked from the CSHTML worked but doRemoval required all the extra plumbing.

Because you need to set default value for checkbox like below:

<form asp-page-handler="LineNumber" method="post">
<div class="modal-body">
<div class="form-group">
<div class="custom-control custom-checkbox">
<input type="checkbox" class="custom-control-input" id="customCheck1" name="customCheck1">

</div>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
<input type="submit" value="Go" class="btn btn-primary">
</div>
</form>
with this on CSHTML.CS
public void OnPostLineNumber(bool customCheck1) // I have tried both int and bool
{
string Message = $"Handler fired for {customCheck1}";
}

Hi andrewcw,
You could use [BindProperty] attribute.Here is a simple workaround like below:
1.Index.cshtml:
@page @model IndexModel <form asp-page-handler="LineNumber" method="post"> <div class="modal-body"> <div class="form-group"> <div class="custom-control custom-checkbox"> <input type="checkbox" asp-for="customCheck1" class="custom-control-input"> <label class="custom-control-label" for="customCheck1">Check this custom checkbox</label> </div> </div> <div class="modal-footer"> <button type="button" class="btn btn-default" data-dismiss="modal">Close</button> <input type="submit" value="Go" class="btn btn-primary"> </div> </div> </form>2.Index.cshtml.cs:
public class IndexModel : PageModel { public void OnGet() { } [BindProperty] public bool customCheck1 { get; set; } public void OnPostLineNumber(bool customCheck1) // I have tried both int and bool { string Message = $"Handler fired for {customCheck1}"; } }Best Regards,
Rena

Hi Rena
My OnPost was from a moda;Dialog that contains also a string , an int.
When I added your suggestion
<div class="custom-control custom-checkbox">
<input type="checkbox" asp-for="doRemoval" class="custom-control-input" id="doRemoval" name="doRemoval">
<label class="custom-control-label" for="doRemoval">Check for Removal, Default unchecked ...</label>
</div>
and added it to other bind variables
[BindProperty(SupportsGet = true)]
public bool doRemoval { get; set; }
Then public void OnPostLineNumber(int id,string ATA, bool doRemoval)
{
string Message = $"Handler fired for {id} with {ATA} and Removal Requested { doRemoval}" ; // NOW WORKS
I am still puzzled why the 2 other variables id, ATA - with just name attribute linked from the CSHTML worked but doRemoval required all the extra plumbing.
But it fixed the problem !!! Thank you !!!
