Asp.net - Grid View - View State For Nested Controls?
Jul 14, 2010
I have a grid view with a nested text box in it.I would like to turn view state off but the fact of the matter is when data is posted,the text boxes inside the gridview aren't available (there are no rows in the gridview on postback). Control's information is not stored in the View State (for things like selected value and .text etc.):Control state,introduced in ASP.NET version 2.0, is similar to view state but functionally independent of view state.However,control state cannot be disabled. Control state is designed for storing a control's essential data (such as a pager control's page number) that must be available on postback to enable the control to function even when view state has been disabled.

I have Parent grid view (gvServiceDetail) and child grid view (Gridview2) in Parent grid view. Child grid view has 3 bound column. In Parent grid view I am binding Partnername,Area,Mobile and in child grid I am binding services against partnerid.
Now I want to edit service details row in child grid view.
i have a grid view with some coulmns like Name,Phone no etc with Edit,Delete column in grid view. I click a row in grid view to Edit,it goes another page where i can edit all fields .Once i update i redirect the page to gridview. I want the grid view to remain in that particular page say 4 of the grid view
It happened to add an extra Gridveiw Header in row_databound event , It did worked fine on !Postback but disappered on Page.Postback . Quick google search guided me to move the event to Row_Created event and every thing is okay .
Can any expert post some pointers , differnces between grid row_created vs row_databount with some sample table data created dynamically behaviour of both the events in !Postback and page.Postback .
I am doing a online web application whereby user is able to enter in new template as well as search for template. The Add template is located outside the grid view and if user clicks on the button, it will load the grid view that is populated with data as there is a row of empty fields at the bottom. However when I click on the Add Template button, the grid view does not appear.
This is my business logic that I used it to search for records as well to click on the Add Template button to add in new records:

public void gv_RowCreated(Object sender, GridViewRowEventArgs e) { if (e.Row.RowType == DataControlRowType.DataRow) { int total = Convert.ToInt32(e.Row.Cells[1].Text) + Convert.ToInt32(e.Row.Cells[2].Text) + Convert.ToInt32(e.Row.Cells[3].Text) + Convert.ToInt32(e.Row.Cells[4].Text) + Convert.ToInt32(e.Row.Cells[5].Text) + Convert.ToInt32(e.Row.Cells[6].Text) + Convert.ToInt32(e.Row.Cells[7].Text); ((Label)gv.FindControl("Label8")).Text = Convert.ToString(total); } }

Have a GridView with a templated select button hidden and using
e.Row.Attributes.Add("onclick",Page.ClientScript.GetPostBackEventReference(this.grdMaster, "Select$" + e.Row.RowIndex.ToString())); to select a row .
When user like to update the datasource he will select one row from gridview then in selected indexchanged event i would display the selected row values beneath the form under the grid , Then user will update the contents displayed from grid and click an update button which is outside the grid . After updating the displayed row , i got to get the values of the next row in the grid and display them for next updation , i'e if users maually selects row 3 from grid then he can update the values using the update button and then on update click itself i'll have to display next row contents of row 4 and this process could go on .
I have a grid view that does add, edit update and delete. ( I draged the grid to the aspx page ) it is working. I would like to have the following : once I lick on edit, I open a form inside the grid view to edit the fields. How can I do that.
If i have a page which displays all the data but with only a few fields, then i select one of the data and then i want to be able to view that data with all the fields related to that data on another web page.
I have been able to view the data in Grid view and enable the Select, Update, Insert and Delete. But not able to use the select button to view the information on another web page.
I just want to bind controls to the grid view but i want to do it dynamically.As an example i just want to enter students marks to text box to adjacent subjects??
thinks students are in row's and subjects are in columns and it similar to matrix in mathematics . but some times no of students and no of subjects are vary.
and here is my code that parses the xml and tries to bind the grid. What am I missing here?
var retVal = service.GetTripDetailsByTripID(tripId); var xmlTrips = XDocument.Parse(retVal); var tripTolls = from t in xmlTrips.Elements("TripTollCompleteDC") select new { TripTollId = (int)t.Element("TripTollId") , DMSLaneModeID = (int?)t.Element("DMSLaneModeID") , HOVOnly = (bool)t.Element("HOVOnly") , CreateDateTime = (DateTime)t.Element("CreateDateTime") , ConfigVTMSDelaySeconds = (int)t.Element("ConfigVTMSDelaySeconds") }; grdTripDetails.DataSource = tripTolls; grdTripDetails.DataBind();
I realize these are anonymous types. Is that a problem? I have verified the service is returning the Xml as stated above. Can anyone out there point me in the right direction? Just for completeness, here is the grid markup <asp:GridView runat="server" ID="grdTripDetails" />
