Data Controls :: Data In GridView Not Getting Updated In Database
Nov 12, 2013
I have used the same steps that you have used on your sample for inserting, deleting and updating. This is my code
private String strConnString = ConfigurationManager.ConnectionStrings["CustomerConnectionString2"].ConnectionString;
protected void Page_Load(object sender, EventArgs e) {
if (!IsPostBack) {
BindData();
[Code] ....
It is deleting the data but not updating the data,it sticks to the same data after clicking on the update button...

i want to compare my database value with my new updated value. what should i do ? e.g : on page load i am excuting one procedure which bring 10 columns and fill it against the 10 fields using for loop on the page. then i am changing value of two columns. ok. when i press update button then there is one more procedure which updates all the new and old columns into database. Its working fine. just i want to know that, should i update only two columns(which are modified) insted of updating all 10 columns ? Is there any csharp code that brings my page load columns into array and then compare it with new ones and updates only those columns which are mismatch with array. i am not sure but there is some way to do this.

Lets take an example of online ticket booking system. Many users could be booking the tickets at any point of time. a GridView displays the list of Allotted and Free seats If a seat gets booked, this information must get updated in all the opened pages in user's browser. User need not require to refresh the page to see if a seat is booked or not Should i put GridView in update panel and keep looking into the databse constantly ??? This could turn out to be a heavy work if databse is too large any other alternative?? or should i stick with the above approach....?

I have a simple grid with 5 columns. The first 4 are numeric values I have formatted with templates. The last column is a total and I've added the Update button on the end. When the Update button is pressed, I have it updating the table with the new values and calculating the Total column. My goal is to have the Total column calculated after each cell is updated and not when the Update button is pressed.
I've added CommandName="myUpdateRowTotal" to
my templates.
<ItemTemplate>
<asp:TextBox ID="R01_Item_txt" CommandName="myUpdateRowTotal" runat="server" BackColor="White"
Font-Names="Arial" Font-Size="10pt" ForeColor="Blue"
Text='<%# Bind("R01_TARGET_COMMISSION", "{0:###,###,##0}") %>'
Width="75px"></asp:TextBox>
</ItemTemplate>

There is a very common problem I am facing in my new webproject in gridview control.The sequence of the execution of the process is as follows:There are some search parameters in SearchPage with a gridview. In gridview's rows there is an Edit button.By providing search parameter(s), data populated to gridview and if we click edit button a new page opens as a popup to update record.In new page the record is updated fine. On successful updation user close the window but he goes to the Search page he again finds the same record with the same parameters to see changes it remains unchanged.Its only changed when he search another record and then again provides the previous parameters.I don't know why is this behaviour of gridview?
Any idea would be helpful.

I have a grid view that is dynamically created.In which every cell in the girdview has a 2 textbox (cTxtboxQty,ctxtWorkOrder) and 2 label.
When user click on the cell, a pop up come out and user are able to change the text inside the cell and click save.After that the pop up close and changed data immediately reflected on the screen.
My problem is:
After my data are changed and updated to database on the pop up page and having it post back to the parent page , my dynamically created textbox in gridview retain old value even new value has been assigned to it.
This sound very weird but i have no idea how to solve this.
My client side code is as below :
[Code]....
[Code]....
[Code]....
[Code]....
I have tested many times and find out that it might be the page hold the old value in memory, so that even we have updated the textbox value, after postback, it still keep and show the old value?

I'm currently working on a small project and therefore created a gridview, including one bit column which has been linked with a checkbox in both the itemtemplate as the edititemtemplate (autopostback = true).Databinding for these two checkboxes has been linked (two-way) to the bit column.Now I want to display the gridview to end-users. They should be able to just click on the checkbox so they value in the database column gets changed as well (as I want to run update queries behind it), but not passing via the command column 'EDIT'.=> problem I'm having now is that the bit column in the database doesn't get updated.

I have a cascading dropdownlist. The first drop down is for Departments and is databound on PageLoad from the database. The user then selects a department and the second dropdown is populated with the appropriate sub departments via JQuery/JSON which calls an httphandler. The problem is as follows: I select a department and the subdepartments are filled.
I finish what I'm doing on that screen and everything is fine. But then if I go to a different screen and add an additional subdepartment then come back to original screen, the new sub department won't appear in the cascading dropdown. I have to close the browser and restart the session in order for any new sub departments to appear even though they are in the database. I put a breakpoint in the httphandler and noticed that it is only called once per session per each department in the first dropdown. I don't know why this is happening. I want it to call the httphander EVERY time the index of the department dropdown is changed.

I have been trying to achieve the following:
1-Allow the user to change the quantity in a textbox i.e // "txtQuantity"
2-capture the newly entered quantity i.e //int integerNewQuantity= int.Parse(textNewQuantity.Text);
3-update the database using the newly entered quantity i.e. //UpdateItem(data,integerNewQuantity)
Problem:1-I have not been able to capture the text i.e. the newly entered quantity i.e. the value entered in the text box "txtQuantity"
2-Hence the database is updated using the existing value and NOT the new value unless I make a constant assignment as below:
textNewQuantity.Text = "2"; When tested the assignment of any number correctly updates the database. see the c# code:
C# code: Version.1
protected void btnUpdate_Click(object sender, EventArgs e)
{
txtItemDescription.Text = txtItemDescription.Text + "from btnUpdate talking.."; [code]....

I have an image file to be uploaded and to be updated in my database. I've already write the C# code based in a VB code.
However, I have some trouble to pass a data to be updated through DetailsView Control, by using
DetailsViewUpdateEventArgs e
The column in database is "ImageData"...
In VB the Code is:
e.Values(
"ImageData"
) = imageBytes
ImageBytes is an array of bytes..

I have a search option which a person can use a multi select listbox. I have it coded so it would loop through to see if its selected or not. I also have a stored procedure where the sql statement is coded for the select statement. For some reason, its not populating my gridview. Where am I doing wrong? Below is the code and stored procedure.
