Put this inside a method like this- protected void test() { string txt = TextBox1.Text.ToString(); }

Upendra Pratap Shahi · Answer

Table objT = (Table)placeHolder.FindControl("tblPerson"); foreach (TableRow objTR in objT.Rows) { foreach (TableCell Cells in objTR.Cells) { TextBox txt = (TextBox)Cells.FindControl("textbox1"); TextBox kishan = Page . FindControl(name_id)as TextBox; string query = "select nid from mstInvestor";

Upendra Pratap Shahi · Answer

Its a normal error what you are getting. Please provide the code for proper solution. Hint: In your code there is some object which is NULL. and you will be trying to read some property value of that object. This is the reason for the Object reference not set to an instance of an object. go through below link- http://forums.asp.net/t/1808030.aspx?How+to+fix+object+reference+not+set+to+an+instance+of+an+object+

How to find value of text boxes....??

Rajeev Punhani · Answer

Please tell in which line error is coming.I think TextBox kishan = FindControl(name_id)as TextBox; is where you are getting error you have not used (TextBox)Cells. in this line. Anyway issue will be in finding control .

Kailash Polai · Answer

Hi, Please debug and see on which line you are getting the error. Normally you are finding controls tblPerson and textbox1 i think here you may not get the object if the ids is not same as above. 1. In some cases you have to specify the ClientIdMode="Static" in the controls tags. 2. you can set the runat="server" so that you can dirctly get the control in CS

Kishan shekhada · Answer

Table objT = (Table)placeHolder.FindControl("tblPerson"); foreach (TableRow objTR in objT.Rows) { foreach (TableCell Cells in objTR.Cells) { TextBox txt = (TextBox)Cells.FindControl("textbox1"); TextBox kishan = FindControl(name_id)as TextBox; string query = "select nid from mstInvestor";
