Apr 27, 2010
I have a Gridview set up so when a user clicks the various buttons it sorts the results. I have a couple problems. Right now the way i have the viewStates set up, it is only working when the buttons are clicked twice. I Was also wondering how to set up the viewstates so it binds properly when the editing and updating. I have read up on ViewStates and I am still a bit confused.

I have a Gridview with these parameters:
<asp:GridView runat="server" ID="ItemGrid" CssClass="Grid"
AutoGenerateColumns="false"
AutoGenerateDeleteButton="true" OnRowDeleting="RowDeleting"
AutoGenerateEditButton="true" onRowEditing="RowEdit"
OnRowCancelingEdit="CancelRowEdit" onRowUpdating="RowUpdating"
DataKeyNames="Item_ID">
<Columns>
<asp:BoundField HeaderText="Item" DataField="Item"/>
<asp:BoundField HeaderText="Family" DataField="Family"/>
<asp:BoundField HeaderText="Structure" DataField="Structure"/>
<asp:BoundField HeaderText="Updated" ReadOnly="true" DataFormatString="{0:d}" DataField="Updated"/>
</Columns>
</asp:GridView>
On updating it calls:
protected void RowUpdating(object sender, GridViewUpdateEventArgs e){
int Item_ID = (int)this.ItemGrid.DataKeys[e.RowIndex][0];[code]...
It generates the Update/Edit/Delete buttons, my Delete function is working exactly how I want and the 'Edit' button generates editable TextBoxes as it should.
My problem is in the updating part, the strings Item, Family, Structure are getting the old values, not the new values I put in the generated text boxes.If I hard code in values they are updated to the database and the DateTime.Now is always updating correctly in the database so the update query is working.
I've been looking at this/reading forums testing things for a couple days now. I'm sure I'm just missing something simple that I have overlooked.
Edit:It has been answered but for those who were curious this is my dataBind();
protected void dataBind()
{
ItemTableAdapter taItem = new ItemTableAdapter();
this.ItemGrid.DataSource = taItem.GetActive();
this.ItemGrid.DataBind();
}

I have a gridview, and I was trying to use SQLAdapter for the first time. I have it set up but I want the user to enter a Date in the last field of the Gridview and be able to update it. I was looking up examples, and I cannot get it to properly update. The field I want to be able to update is the "TADateUpdate" I have gotten it to show the texbox fields to edit, but I can't figure out a method to update properly.

In one my web page i've an updatepanel which contains a gridview .The gridview displays huge amt of data (4 pages of data) and the updatepanel refreshes for every 1 sec,for tht i've used timer control, to get the updated data from the server.for that i've used one timer. The problem is ,the webpages scroll bar(both horizontal and vertical) is repositioning to the starting position after every refresh.

This is a great idea, but it's implemented for sharepoint .Wonder if there is a solution for regular asp.net pages, which does the same, caches viewstates.

I have loaded up a gridview object with data. I have turned on Edit on the grid. It lets me edit the data, but I also want to put some code to check for correct data in each field. I tried to assign a requiredfieldvalitor, comparevaliditor but they don't work. Is there an event I can capture to fire up some code before the grid sves my data?

I have a gridview which has editable columns.
The gridview lives in a formview, which lives in another formview.
Inside one column is an end date. This column has a textbox which gets it's value when I choose a date from a calendar control. However, when I choose a date from the calendar control, the program crashes instead of populating the text box.
Here is the page and the selectedIndexChanged sub for the piece of work I'm trying to accomplish...

I have a Gridview where the user can edit a row when he click on "Edit" (this is called update mode i thinck?).
When the editing is done, the user clicks on "Update" and the changes are written into the database. Additionally i set a "ChangeMarker" in the database that the data record has been changed by the user.
I identify the row in the database i want to update with the SelectedDataKey in the Gridview:

In the first line where I dim EdittedRow i got an error: "Object reference is not set to an instance object". I dont understand this error message.
