Forms Data Controls :: GridView Not Updating Correctly?
May 14, 2010
I'm using a GridView to retrieve data from a stored procedure using a SQLDataSource (db is SQL Server 2008). When I compile my application and go to my website, all the data is loaded and shown fine. If I was to add a new entry to the table however (a seperate page on my website has a Wizard control to facilitate this) and then return to the page with the GridView, the new entry doesn't show up.
Looking from SQL Server, the data has been added, but the GridView isn't updating to show it. If I were to recompile the project with F6 and refresh the page, the new data will show up. I tried calling DataBind() on the GridView in the Page Load event, however the issue still remains.
I have a GridView in ASP.NET. I have an Edit CommandButton for every line in the GridView to edit the data on that line. All of this works fine except for the fact that when the user clicks on Update, it does not update with the correct value that the user entered. I have this as a Template field with the textbox to edit bound to the field, so it updates when the user changed the value and clicks Update. However it does not work. I have tried almost everything and its very frustrating. Here is the code for the Data Source:
<asp:SqlDataSource ID="Table1DataSource" runat="server" ConnectionString="<%$ ConnectionStrings:ConnectionString2 %>" InsertCommand="INSERT INTO TABLE1(ProjectId, WBS, WBSTitle, VersionId) VALUES (@ProjectId, @WBS, @WBSTitle, @VersionId)" DeleteCommand="DELETE FROM TABLE1
I've created a page called "EditItem.aspx" where a user can edit a row in a database. On EditItem.aspx.cs, the pageload function grabs the correct row from the database (by grabbing the querystring in the url). The form is populated with all of the correct data. I've got a button onclick that runs this code:
[Code]....
But the changes do not apply. However, if I set static information (so the information is not being grabbed from fields on the form) into the SQL string, I can click the button once, nothing will happen, but if I press it a second time, THEN the information will be passed to the database.
In the following code, the user documents types are not getting updated, they do initially but don't stay updated. perhaps you can see something blatant here:
I have problems with GridView control which has template field with checkbox in it. My primary concern is that same code works for all the other GridView controls I have in different webforms, but not in this one.
This code is supposed to get the identities (ID column in GridView) and then get the values of first two selected and finally redirect them to another webform as querystrings. I double checked the GridView and they are identical (except they are binded to different datasource).
I have a GridView with a Template Field set to Checkbox. Issue is; when I click the asp:button I placed beneath the GridView to update the database, I do not get a checked value on the returned button. So it just skips my code and nothing happens.

Then I have my Method.
[Code]....
So when the code gets to this line if (cb != null && cb.Checked == true), the value is always False even for the checked box.
I have a gridview with 1 field that is setup to display my clients content from the DB. Within their console, i have setup to allow them to enter that fields data with HTMLEditor.The field is setup with HTMLEncode = true but anything done to the text is being displayed as actual html code on the site, so all the html tags are shown and so on. Nothing has changed on the site now for about 2 months( with the actual .aspx pages ) they are only allowed to update the content. Can anyone tell me what i can check or change to insure that the content is displayed correctly to the browser?here is the aspx code for that field:
I have 2 gridview controls gathering data from 2 different tables and I want them to line up on the screen so they look like one big table.
Each table has the same number of columns but the 1st columns on each grid view don't line up. Both are set to 200px, all other columns are 40px. The data in one has say 5 letters in the 1st one and 25 letters in the second one.
Is there a setting I need to use to make each column 200px?
What I need to do is to compare the values for the previous day to see whether it is greater than today's and then return an image in an Image templatefield in a gridview. Below is my gridview:
[Code]....
Basically, the imgUrl method should return the correct indication in the gridview image template field. For instance if the sprice(which is today's values) is greater then the previous an uparrow should appear. However, I notice that the conditions is not evaluating correctly, for instance the Bank_Name FCMB in the table still returns an uparrow even when its share price is down from the previous day value.
I have a parent gridview which has a child gridview in the itemsTemplate. Both are binded to different SqlDataSources. I can successfully update and delete rows in the child gridview. After updating in the child gridview, some related data in the parent gridview are not updated automatically. So i have placed ParentGridview.Databind() in the rowupdated event of child gridview. But it doesnt look working.
I have a page with an updatepanel, which at runtime has controls dynamically created. The controls are saved within the cache, and readded to the page upon postback each time when needed. Sometimes the controls need to change, sometimes not. In most of my cases, if I just re-add the control to the page without any changes to the control AJAX will leave the control alone on the client-side leaving me with what I expect to see, which is no change. If I make a change, it obviously updates correctly.
Now, I have added a literal control which defines an iFrame which points to another page. ie:
If I re-add this control on postback, with a change, I get the item on the page as I expect. If I make no changes to the .Text and simply re-add the control to the page, it flashes as though it has been changed and then re-requests the page defined by the src. The whole point of me caching this, is to stop the client-side from updating a control that has not changed, removing a flashing screen and all the resizing that goes with it.
I am using LINQ to SQL and on my DetailsView it updates fine but with my gridview it is not. Both I used template fields so I am not sure what the issue is?

I have been doing a lot of reading and searching and I cannot figure out why this is not working for me.
I have a gridview which contains a dropdownlist inside a TemplateField. The ddl appears correctly and seems to work ok but it isn't updating the table despite being bound to a field.
It does not give me any errors and seems to work but the grid view cell do not take this session. When I'm clicking on the edit hyperlink this event is triggered.
Having a bit of difficulty working this gridview update problem out - I have managed to get edit/update function working but instead of only updating the current gridview row it is updating the whole table I believe this is due to a missing where statement on my Update statement - to single out the row index of my grid row.When I configure my sql datasource I am using custom statements Here is my update statement
I have a gridview that holds 4 columns. in the fourth column there is a DropDownlist that holds three items.
I want my users to select one of the values and when they do the auto post back (which is set to true) should execute a method that updates the database selected row. But do i use the selectedindexchanged of the DDL or the Gridview? My head is totally thrashed so i imagine its really simple and im just over thinking it.
i wanted to refresh the gridview once user enters values and clicks update button. But its not updating. If i change my selection to pop up gridview, then it is showing the updated values. I dont know where i am doing wrong. can any one suggest changes in my code?
where I have gone wrong? changing from VS2003 DataGrid to VS2010 GridView; still on SQL Server 2000 so the wizards for autogenerating the code are not compatible.
Delete works, RowUpdating does not. I get an ArgumentOutOfRangeException on "rowToUpdate("QuoteDQty") = Me.dgQuoteList.Rows(e.NewValues.Item(1).ToString)" Private Sub dgQuoteList_RowUpdating(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewUpdateEventArgs) Handles dgQuoteList.RowUpdating [code]...
I have a gridview with the ObjectDataSource and the Update does not work. When I click on Edit, I go to Edit mode but Update will not work at all. No errors. I do believe that it is in the RowUpdating method but cannot figure out how to call the method UpdateBook from the BookManager BAL.
BAL BookManager

Gridview

RowUpdating

Put in Breakpoints and it is getting to the RowUpdating but will not update.
