Posted on by Ahmad Ali

I am making an app for a school in which there is a screen to add students to the record. The code gave no errors untill i tried to add a student. The code i used is the following:

If(
    IsBlank(txtStudentName) || IsBlank(cmbStudentClass.Selected),
    Notify("❌ Please enter student name and select a class.", NotificationType.Error),
    Patch(
        Students,
        Defaults(Students),
        {
            Title: txtStudentName,
            Class: {
                '@odata.type': "#Microsoft.Azure.Connectors.SharePoint.SPListExpandedReference",
                Id: cmbStudentClass.Selected.ID,
                Value: cmbStudentClass.Selected.Title
            }
        }
    );
    Notify("✅ Student added successfully!", NotificationType.Success);
    Reset(txtStudentName);
    Reset(cmbStudentClass)
)

See my response in your other thread.

You are using the control as input but need to define ".Text" on txtStudentName

@Ahmad Ali,

Patch(

  Students, // Syntax Correct - DataSource

  Defaults(Students), // Syntax Correct - Defaults(DataSource) used for New Item Creation

  {

Title: txtStudentName,// Wrong Syntax

}

)

Assume txtStudentName is mapped to the control text box named as txtStudentName If the onchange event of text box is written Set(vartxtStudentName,txtStudentName.text) then you can pass the Title : vartxtStudentName but here Title Column is expecting Text Value but you are passing control value hence casting of objects is not happening so powerapps throwing the error.

Correct one

Title: txtStudentName.Text,

or

Using variable get the data

Set(vartxtStudentName,txtStudentName.text)

Title: vartxtStudentName,
