Reading Hashtable in Report

[Prasant]

I want to show the Hashtable data in textbox of Telerik report. My class structure is like:

Public class MyClass
{
public Hashtable ValHash { get; set; }
}

MyClass obj = new MyClass();
obj.ValHash = new Hashtable();
obj.ValHash.Add("Name", "Prasant");

While setting Hahtable value to textbox, as:
this.textBox1.Value = "= Fields.ValHash[\"Name\"]";

I am getting an error as "Missing operator before '["Name"]' operand.

Am i doing anything wrong?

Hi Prasant,

Our expression engine does not support indexers, and that is how the values in a Hashtable are accessed, using an an indexer by Key. We can suggest you two approaches:

• Flatten your data in a DataTable object, e.g. the Key is a Column, and the Value is the value for that column, then you can bind the TextBox item to the field with the corresponding column name;
• Have user-defined function to get a value by key from the Hashtable as illustrated in the attached sample. The function is used as an expression for the TextBox item Value property, where we pass the Hashtable object field and the searched key;

I hope this helps.
