you can't, not without some sort of intermediary, like a service on the server that hosts them both, to store/pass the value. Of course, your next problem is, which session on app a, is related to the session I am accessing in app b, I assume there's a username the two apps have in common or similar that you can use for this.

It seems that your are accessing the file PrjDailUpdatesExtElt in the button click event handler...Make sure that the file actually exists..Also see FileModes if you are writing to the file...

Hi,

I am working with asp.net page.I have a drop down list which displays values(like 1,2,3,4....).Now what i want is based on these values we must generate a textbox.
E.g: Dropdown list value = 1 1 Textbox must be generated.
value = 2 2 Textboxes must be generated...So on...

I have added a place holder and tried with Events of Dropdown List...

But i am unable to generate any text boxes...Please help

Thanks in Advance
Fast

First set the AutoPostBack property True for DropDownlist and handle the SelectedIndexChange Event.

void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
{
     int txtCount = int.Parse(DropDownList1.SelectedValue)
     for(int i=0;i<;txtcount;i++; )
     {
           TextBox txtBox = new TextBox()
           //Assign id and some customization for each textbox
           ....
           .....
           placeHolder.Controls.Add(txtBox)
      } 
}

Be careful, there is no Undo Button(Ctrl+Z) in life.

That approach will generate the texboxes, but since it is created after viewstate events, ASP.NET will not maintain viewstate for it. Thus the values entered in the texboxes will not be persisted across postback.

Think textbox doesnt use viewstate for maintaining the text across postbacks
Even if the viewstate is false,text will be still maintained during postbacks
Correct me if i am wrong.

I suggest you to put the textbox in a template column inside a GridView, and bind the gridview with a datasource which will have necessary rows. If 1 is selected, make a 1 row data source and bind it to the grid. ASP.NET will maintain viewstate for the texboxes along with parent control, GridView.

That is a good one...but i am also trying to store this data which is entered in textboxes into a database..How can i handle this...
Eg: I am working on registration in Hotel:
I can select values from drop-down list(From 1 to 8) and dynamically creating the text boxes.
I need to enter user information of all the residents.
So,If there are 2 text boxes and user enters information how can i bind and store into database...like the number of people keeps on changing right dynamically.....
My database have name field,address field..
All the members required to enter the names but on same address...
How to store these names into database as they are in random number.

Thanks,

Loop through the gridview rows, find each texbox and save value to database.

How do you pass values to a datasource

Hi
I am very new to this, but I would like to know how to pass a value to AccessDataSource as a parameter in order to update a table.

I have a dropdownlist, and I am able to grab the selected item from the dropdownlist, but I am to get the value into the DataSource and to then update the table.

Can someone explain to me or show me how.

Thanks

Re: How do you pass values to a datasource

sana171-Feb-09 22:20

1-Feb-09 22:20

you can use : (If you have set NONE to parameter field while configuring datasource)

Accessdatasource1.UpdateParameters.Add("@parametername","parametervalue");

parameter value can be any value you are retrieveing from dropdownlist or textboz or any variable.

there are other ways too, by sessions or querystring etc Smile | :)

Good luck!
regards,
Sana
