tgis is very simple.Did you try something?
Dropdown's selectedindexchanged event is called only you one change the index if selects the same again and again then it is not callled and there is no postback occurs in this scenario.

thanks for the reply, In fact you are true, but what happens when you first select Index 1 then index 2 then again index 1, I am sure I will do a postback which I dont wanted to do. I would like to store it at some client side variable. any ideas?

When changing the selected Index, fire a javascript function which check whether the selected index is in the list of values stored in hidden variables if it is return false from the Javascript Method.

Your question is not clear.

But as I understood, if you want to do some modification in displaying the data in gridview, hen you can do it in GridView.RowDataBound event.
For details of this event have a look

No, My question is how can we get that data from string array.

i ll explain it briefly.

there is a multiline textbox where user can copypaste some data like this

Sreejith
604 E 25th St
Chennaie, WY 82001-3133
Phone: (45) 67-64456

Rajesh
1609 E 19th St
Chennaie, WY 82001-4990
Phone: (453) 564-95654

Ramesh
1002 Rumsey Ave
Codys, WY 82414-3533
Phone: (307) 587-3008

this details may vary according to user input.

i am assigning this values in a string array.

string[] strData = strPasteData.Split(new string[] { Environment.NewLine }, StringSplitOptions.RemoveEmptyEntries);

while running if i insert a breakpint here and checking for data i am vieing data like this

str[0]="Sreejith"
str[1]="604 E 25th St"
str[2]="Cheyenne, WY 82001-3133"
str[3]="Phone: (45) 67-64456"
str[4]=""
str[5]="Rajesh"
str[6]="1609 E 19th St"
str[7]="Chennaie, WY 82001-4990"
str[8]="Phone: (453) 564-95654"
str[9]=""
str[10]="Ramesh"
str[11]="1002 Rumsey Ave"
.
.
.
.

but my question is how can we this dynamic data into into gridview

ie in my gridviw there are 4 columns

Name
Address
Address2
Phone

I ve to assign values from string array to corresponding fields

In first row i need

Sreejith,604 E 25th St,Chennaie, WY 82001-3133,Phone: (45) 67-64456

2nd row

Rajesh,1609 E 19th St,Chennaie, WY 82001-4990,Phone: (453) 564-95654

this is my requirement

Known is a drop, unknown is an ocean

You can not directly bind it in gridview in this form.As Abhijit suggested, create a datatable with your column names and add all the records as seperate rows like for

Sreejith
604 E 25th St
Chennaie, WY 82001-3133
Phone: (45) 67-64456

DataRow dr = dt.NewRow();
        dr["Name"] = "Sreejith";
        dr["Address1"] = "604 E 25th St";
        dr["Address2"] = "Chennaie, WY 82001-3133";
        dr["Phone"] = "Phone: (45) 67-6445";
        dt.Rows.Add(dr);

//similarly do it for all the records. and lastly execute the line
 dt.AcceptChanges(); 
//Now bind the datatable dt to your grid.

Hope it'll help

Cheers!!

Hi,

That I know.I think still you are not clear about my question,

u r telling to do it as static.But my qn is how to do it dynamic?

ie instead of

DataRow dr = dt.NewRow();
dr["Name"] = "Sreejith";
dr["Address1"] = "604 E 25th St";
dr["Address2"] = "Chennaie, WY 82001-3133";
dr["Phone"] = "Phone: (45) 67-6445";
dt.Rows.Add(dr)
dt.AcceptChanges();

i need to get all data from that string array.
DataRow dr = dt.NewRow();
string[] strData = strPasteData.Split(new string[] { Environment.NewLine }, StringSplitOptions.RemoveEmptyEntries);

dr{"Name"]=strData[i].ToString();
dr["Address1"]=strData[i].ToString();
dr["Address2"] =strData[i].ToString();
dr["Phone"]=strData[i].ToString();

Sreejith604

Phone: (45) 67-64456

consider the above data as 1 single record

but the problem is user will paste about 10 record at a time in a multiline textbox.

Here "" is the delimiter.if user entered 10 record there will be 9 ("")empty string to separate different data.

so similarly you can add the rows in table dynamically,If you user pastes 10 or record, as you are readin string ,have a loop of he no of recods that user pasted and add the row dynamically based on the entered text.and at last bind it to the gridview.

Might be i cannot understand your proble, but if you know yje delimiters then you can create dynamic datatable as well.

Try to use DataTable and DataRow and then assign the DataTable to GridView Source.

DataTable dt = new DataTable("Table1");
      dt.Columns.Add("Name");
      dt.Columns.Add("Address1");
      dt.Columns.Add("Address2");
      dt.Columns.Add("Phone");
      DataRow dr = dt.NewRow();

Now add value for dr["Name"], dr["Address1"] ..... Finally Do the AcceptChange for Data Row. Create New Row for new records ( In your case it is "") and finally Assign the Data Table to GridView.

Cheers !
