Syntax error ',' expected.

Ramco Ramco

I am getting error after writing below code - Syntax error ',' expected. The name address1,address2 does not exists in the current context.

htmlTable.Append("");

htmlTable.Append("");
    htmlTable.Append("");

    string deleteAttributes = Status == "Blocked" ? "style='pointer-events: none; opacity: 0.5;' onclick='return false;'" : "data-toggle='modal' data-target='#modal_Delete' ";
    htmlTable.Append($"");

    htmlTable.Append("");

    htmlTable.Append("" + row["docentry"] + "");
    htmlTable.Append("");
    Count++;
}
htmlTable.Append("");
htmlTable.Append("");
PlaceHolderTable.Controls.Add(new Literal { Text = htmlTable.ToString() });

Thanks

It looks like there are a couple of issues in your code. The error message suggests that there might be a syntax error and that the variables address1 and address2 are not recognized in the current context. Here are a few things to check and correct:
1. Syntax Error: Ensure that the double quotes inside the string are properly escaped. You can use @ to create a verbatim string literal to avoid escaping issues.
2. Variable Context: Make sure that row["address1"] and row["address2"] are accessible in the current context. If they are not, you might need to pass them correctly.
Here’s a revised version of your code:
```
htmlTable.Append(@"");

htmlTable.Append("");
htmlTable.Append(@"");

string deleteAttributes = Status == "Blocked" ? "style='pointer-events: none; opacity: 0.5;' onclick='return false;'" : "data-toggle='modal' data-target='#modal_Delete'";
htmlTable.Append($"");

htmlTable.Append("");

htmlTable.Append("" + row["docentry"] + "");
htmlTable.Append("");
Count++;
htmlTable.Append("");
htmlTable.Append("");
PlaceHolderTable.Controls.Add(new Literal { Text = htmlTable.ToString() });
```
This should resolve the syntax error and ensure that the variables are correctly referenced. If the issue persists, double-check that row["address1"] and row["address2"] are correctly populated and accessible in the current context.

- Fixing string interpolation inside Append method:
  
  The original code incorrectly used "{row["address1"]}", which should be a string interpolation inside a C# string.
  
  Use $"{row["address1"]}" instead.
- Ensuring the loop context:
  
  The code you provided seems to be inside a loop, but the loop itself is missing. I've assumed that the loop structure is there, so I'm keeping the relevant context.
- Closing the loop properly:
  
  There was a closing bracket without an opening one. Make sure the loop structure is closed properly.
Here’s the corrected code:
```
foreach (var row in rows) // Assuming you're iterating over a collection called 'rows'
{
    htmlTable.Append("");
    htmlTable.Append("");

    htmlTable.Append($"");

    string deleteAttributes = Status == "Blocked" ? "style='pointer-events: none; opacity: 0.5;' onclick='return false;'" : "data-toggle='modal' data-target='#modal_Delete'";
    htmlTable.Append($"");

    htmlTable.Append("");

    htmlTable.Append($"{row["docentry"]}");
    htmlTable.Append("");

    Count++;
}

htmlTable.Append("");
htmlTable.Append("");
PlaceHolderTable.Controls.Add(new Literal { Text = htmlTable.ToString() });
```
Key Corrections:
1. Corrected string interpolation: Use $ for string interpolation in C#.
2. Loop structure: Make sure you're iterating through your data source (like rows in the example).
3. Properly balanced braces: Ensure all braces are correctly opened and closed.
If your loop context is different, make sure to adjust it accordingly.
