TextBox does not contain a definition for 'DataSource'

Question

Please help me to fix this issue Since i'm a new to coding Error 1 'System.Windows.Forms.TextBox' does not contain a definition for 'Datasource' and no extension method 'Datasource' accepting a first argument of type 'System.Windows.Forms.TextBox' could be found (are you missing a using directive or an assembly reference?)

Thanks for the reply Mangesh. I changed it accordingly and pasted in my code. textBox1.Text = dt.Rows[0][Categorization].ToString(); it got executed successfully with zero error but failed to pull data from column. I replaced textBox1 with new comboBox4 for cross verifiying it just worked fine with ComboBox4 with below code. -comboBox4.DataSource = dt; -comboBox4.DisplayMember = Categorization; -comboBox4.ValueMember = Categorization; Is there anything i need to take care with textBox1.

Just assign the value of the column like this to the textbook Yourtextbox.text=Datattable.Rows[0][your column name].Tostring (); This will bind the things for you to the textboc

I just want to pull data from table [Resolution]. where my selected combobox3 value is ProblemID and i want my textBox1 to fetch data accordingly from Categorization from same table. comboBox3 is my ProblemID TextBox1 is my Categorization TextBox2 is RResolution TextBox3 is Additionalinfo for example : select CategorizationRResolutionAdditionalinfo from Resolution where ProblemID = '+comboBox1.text+' resolution table structure.. ID | ProblemID | Categorization | Additionalinfo | RResolution i hope its quite clear..

TextBox control doesn't support DataSource property. But in code it is like: textBox1.Datasource = dt1; textBox1.DataSource = dt; textBox1.DisplayMember = ProblemID; textBox1.ValueMember = ProblemID; In above code you are using DataSource property so you are getting compilation error. DataSource property you can assign in dropdownlist control. I am not sure about your requirement why are you assigning DataSource to TextBox. If you want to display data in TextBox then use Text property: textBox1.Text = your data;

Hi Mohmmadif you are trying to acheive this then it is not possible as textbox doesnt have the datasource property thats beacuse the textbox can only hold only one property at a time you can assign the datasource to the DropDown as it will contain the multiple rows in it textBox1.DataSource = new DataTable(); //Your datatable name if you want to use the multiple values in the textbox then u probably need to append the each value of that datarow an assign that string to the textbox...

Hi Share your code first. C# is a case sensitive language and you should check the following content you written in your code Textbox  DataSource .
