Forms Data Controls :: How To Read Data From Gridview
Jun 13, 2010
In my Gridview second row will be a Textbox, when the user types something on that based on business logics we do some calculation and display the result in the 3 rd and 4th rows using Javascript(while Textbox change event), but now the problem is i can type the vlaue and resutl will be displying now i have another button while that button click event i have to read the Gridview data and store back to Database this time i'm reading the data using
foreach (GridViewRow row in gvAmount.Rows)
{
Label userInputField = (Label)row.FindControl("lblTest");
if (userInputField != null && userInputField.Text != string.Empty)
{
Response.Write(userInputField.Text + "--");
}
}
but in the result row i didnt get the answer of result processed by Javascript instead of that its displaying the data of which i have loaded on page load event.

I have a dropdownlist and a button.
When I click the dropdownlist,it will show all the data in a gridview.
Once I click the button,the whole data in the gridview will appear in the dummy table which I don't want it to do that.
What I want is,when I click the button,it will read row by row from the gridview and sent it one by one to my dummy table.
Problem is,how do I read the data row by row from the gridview with only one button?

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 GridView. In my RowDataBound event I add attributes for the mouse onclick event, which sets the row's background color to red when the row is clicked. This works. I have a button outside of the GridView. When I click this button, I want to read each row of the GridView, and if its background color is red I want to perform some processing on the row. I tried the following code and even when the row's background is red, I cannot get its background color (bgc is empty).

I have the following fields in an Appointment table:
ID(PK), TeacherID, DayID, TimeslotID, ParentID, StudentID, Remarks & Editable(bit, Default value=1)
I am developing an application to allow parents to book appointments to meet the child's teachers.
It is compulsory for parents to meet child's mentors, hence Appointments to meet class mentors are already pre-booked in the Appointments table.
Parents could still book appointments to meet other subject teachers. I have a column in my gridview to show parents the list of booked appointments. Parents are allowed to change the Appointment timeslot for an appointment they booked and are not allowed to change appointment time for pre-booked appointments.
Under the Remarks colum, it is stated that the following appointment is pre-booked by class mentor.
How do I make only those pre-booked rows read only since all the appointments belonging to a parent is under one GridView.
I found an example, but this is to only make the 1st 3 rows read-only and I don't think this is in VB coding. I'm usingASP.NET VB coding.

This was working fine and then I was tinkering around and I can't figure out what I did to break it. When I stepthrough the debugger, the for each stmt cannot read values from the radiobutton list or the textbox, it only show "" for each. I double checked the id names between the code behind and the markup.

I have a GridView where some of the BoundFields have a CssClass applied:
<asp:BoundField ... ItemStyle-CssClass="foobar">
In the rendered HTML it looks like <td class="foobar">
But when I try to read the CssClass programatically in an event like RowCreated or CheckboxChanged or PageLoad it returns nothing:
For Each row As GridViewRow In gv.Rows()
For Each cell As TableCell In row.Cells()
ltlMsg.Text += cell.CssClass
Next
Next
(gv is my GridView and ltlMsg is just a Literal for displaying the results)
If I replace cell.CssClass with cell.Text it does display results, so the code is running.
If I change it to cell.CssClass="test" it does set the class of the <td> elements. It just can't seem to read them.
I must have missed something obvious - I've tried putting it in various different events but nothing seems to work. I assume the CssClass must get set at a later point in the event cycle than I have tried. Can anyone recommend a link to documentation that shows the order in which all the events fire?
Eventually I want to use this to show or hide certain columns in the GridView based on whether a CheckBox (outside the GridView) is checked or not.

I have a gridview with a date field. I don't want the user to be able to type in their own date and mess up the format so I made the property readonly. That date is then set by a point and click interface. This is all working fine but when the user clicks update this field doesn't update because it's readonly. If i turn readonly off it works so is there a way to turn off the readonly property right before submit?

I have a webform developed in VB.NET and I am facing a strange problem. In the webform I have a GridView control which has two bound fields (Item # and Item name) coming from a master table and infront of these two fields I have placed a TEXTBOX control as TEMPLATE FIELD to take any value of particular item. But after filling all the textboxes when i clicked on submit button it loops thru the items and there i need to read the textbox value of that particular item in a variable but unfortunately the value is blank even the data is there. Here is the ASPX code.

I am displaying selectable rows in a gridview. The selected row uses a stored procedure to display all the fields in a formview when the Select button is clicked.
Only a small subset of the fields in the selected row are editable. When I click the Edit button only the EditItemTemplate fields show up, the read-only fields from the ItemTemplate disappear. I want the read-only rows to remain visible with the editable rows.
If I include the read-only fields in the EditItemTemplate, I get an error when I click Update on the FormView. The error states that there are too many parameters being passed to the stored procedure to update fields. How can I continue to show the read-only fields with the editable fields on the FormView and avoid getting the input parameter error on the stored procedure for the Update command?
