prasanna p

Hi friends, I have multiple text boxes and one drop down. Itemcode Itemname Batch(drop down) BatchQty When I select itemname through web service and ajax call I am binding Itemcode value.after this I am doing ajax call to bind corresponding Batches to dropdownlist. Again on dropdown select change event(jquery) I am assigning Batch qty value.All are aspx controls. Now my problem is while inserting data into table the values are not coming in code behind(c#.net).dropdownlist.selectedItem.Text and TxtBatchquantity.Text values are null.how can I get the values for Insertion.

HI Prasanna,

Can you share your html with javascript code and C# code?

Yes Ramesh whatever u said is right.I am enabling false those two textboxes Itemcode and BatchQty. Actually I have 7 rows with textboxes and dropdownlist.I am assigning values to corresponding row textboxes and dropdownlist. My problem is I am not accessing dropdownlist selected text and textboxes values while assigning values to disabled textboxes through jquery.

Hi Prasanna,

If you are binding values into asp dropdownlist controls using client side like ajax.
If you want to save that selected dropdownlist values into database in c# (codebehind) didn't get selected values.

You need to use ajax call to the c#.

In Client side:

var obj = {};
obj.DoNo = $.trim($('#hdn_DONo').val());
//alert($('#hdn_DONo').val());
$.ajax({
type: "POST",
url: "pagename.aspx/Insertvalues",
data: JSON.stringify(obj),
contentType: "application/json; charset=utf-8",
dataType: "json",
//success: OnUpdatePrintSucess,
failure: function (response) {
var r = jQuery.parseJSON(response.responseText);
alert("Message: " + r.Message);
alert("StackTrace: " + r.StackTrace);
alert("ExceptionType: " + r.ExceptionType);
}
});

Hi Prasanna,

let me explain my understanding,Kindly correct me if I am wrong,

1. You are binding the Batches and Item code values using ajax method when you select the item name.
2. While you selecting the batch in dropdown list, again you are binding the batch qty using ajax..

Once this all complete , you are trying to insert the record. but the dropdownlist values are null.Am I correct?
