I need to read textbox values or any control
assume that i have 10 textboxes with ID's txt1 , txt 2 ..... txt10
is there any possible way to read them using loop like for to next or any loop control ??
I know this is probably a pretty easy thing to do and it is if I can upload the file and store it onto the hard drive of the server. What I need to do is read the text file into memory and then parse through it one line at a time. Anyone have any code that demonstrates that?
View 8 RepliesI can directly use to read and display Excel or CSV files using asp web control(GridView, sqldatasource etc). I do NOT want to upload the file first to an sql database before reading them, I just want to read the files directly. I am using asp.net 2.0 and c#.
View 3 RepliesI would like to find out if there is anyone who would know how to read from a database then returns the same number of records that a stored procedure returns and display those records on the webpage there after pass the ID of the record to a variable to another stored procedure that displays the data related to the record that was clicked, I tried doing this in a asp.net repeater but I can't seem to be able to reference the controls inside the repeater.

How do I loop through a GridView (the actual GridView, not its data source) to check what's displayed in the first cell (a BoundField with int data) of every row?
View 4 RepliesIm stuck with declaring a string which is in a loop within another loop.

I'm trying to loop through a manually created row's controls in a gridview and set the visible property.
I can use findcontrol and it works fine and I don't have to loop. But there are a lot of controls, so I just wanna do it in a loop. But it never finds the control type I'm looking for. Here's my code:

I'm being able to read first record. If I click Next button, my page goes to next record for only once. If i click several times, nothing happens. Does not go to next available records.
Im trying to input the value in the table into the checkboxes but i keep getting an error that states: "Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index"When i do a quick on this part of the code :"DirectCast(GridView1.Rows(i).FindControl("DescriptionA1"), Label).Text", i get "Run-time exception thrown". This is my first time trying something like that, i have search for solutions but now im more confused than ever.

I have a Bulk Gridview(all rows are editable) I need to loop through.I need to get the text that's displayed in each of the textboxes in the gridview, my current code is this:
[Code]....
like this, I need to loop through the gridview, but instead of just getting the text in each column, I need to get the text from the textboxes. How can I do that?If i'm going to use findcontrol() then I need the ID of each control. the gridview is always created dynamically, which means I don't know the number of controls that's being created beforehand. So, how/where can I find the ID?Is there another way to extract data from the textbox, other than findcontrol()?
What I want to do is programatically set editindex of all listviews to 0. How can I do this?
I want to use a foreach(listview lv in Page.Controls)

I am trying to loop through all gridviews on a page to hide them and set their page index to 0. This should be very easy to do and it seems like the code below should work but it doesn't?? How can I accomplsh this with the least amount of code? FYI- this code is executed on a button click.
foreach (Control childControl in Page.Controls)
{
if (childControl is GridView)
{
((GridView)childControl).Visible = false;
((GridView)childControl).PageIndex = 0;
}
}
I have a web page with several panels. I one particular panel, I have several radiobuttonlist controls. I added a LinkButton to my web page and when clicked, I want to clear the values in all my radiobuttonlist controls. I have this so far:
Protected Sub ClearRBL(ByVal sender as Object, ByVal e as EventArgs) Handles lbClear.Click
Dim ctl as Control
For Each ctl In Page.Controls
If TypeOf ctl Is RadioButtonList Then
DirectCast(ctl, RadioButtonList).ClearSelection()
End If
Next
End Sub
But this does not work. The If TypeOf ctl Is RadioButtonList Then line never finds a RadioButtonList control. How can I make this work?
have created a gridview with input text boxes inside which can be added by the user.
So in order to populate the gridview on form load I use grdView.DataSource = PopulateDT(); this.grdView.DataBind();
Now is there a neat way of retriving the data content after the user has entered data from the gridview and store as a datatable. The only way is doing a for next loop which i think its time wasting.
I have found demos of multi-edit gridview which basically mark each row as edited then loop through them:

How do I loop the gridview to read or insert one row by one row?I have a database which has a Primary key. Currently,all the rows seems to appear at one time.Even when I use a counter,it did read one row from a textbox(which is for my testing to read one row) but in the database,it still inserts the whole rows from the gridview.I can't click button twice as it will occur an error "Primary Constraint".

I have a following scenario - A use selects criterias from a webform (C#) - a result is then returned from the sql. Say, to start, there are 2000 data returned from the sql and are stored in a dataset.
Now, the user wants to choose a number of drops (up to 6) - with the number of drops selected, they can enter their own quantity in each box. So, they can divide the 2000 records into 6 different drops. With each drop, there is campaigncode created based on the mail date and the job number they provide.
So, now i have the 2000 records in a dataset. What i want to do is loop through the gridview where the user fill out the quantity depending on the number of drops (for ex: if they say 3 drops, then there will be 3 rows in gridview with 3 quantity box to fill).
In the loop, I am getting the quantity, dropdate and the job number. The Campaigncode is created as well. Then, i am looping through the datarow in the dataset; updating the Campaign Code column with the CampaignCode for the number of records thats set in a loop. It works but the Campaign Code is not populated for the next set of records.
Here is the code:
[Code]....
I think its this line right here thats causing the problem. But i don't know how to tweak this so as to accomplish what i want to do.
if (Convert.IsDBNull(DSAEFile.Tables[0].Rows[i]["Campaign Code"]))
I have a two gridviews that I populate it through some tables from a database.
In the same page I have a ASP:Button with onclick event.
When click is perform I wish to write a code that compares the old values of both gridviews (that retrieved from database), with the new values, and if changes were made then create the changes in the database.
I think that the best way is to loop every gridview sepertly, and compares it with the values in the database
How do I do that? Do you have a sample code that loops on gridview and compares with the old values to detect changes?
i am unable to handle null values in while .even i tried to handle condition is breaking and coming null value comming inside loop.
