Cant Retrieve Data Entered In First Empty Row Of Grid View
Mar 24, 2011
I have placed grid view in update panel with first row as empty and it is not bound with any data base. Rather I have bound grid view with data table. Whenever I click on 'Add New Row' button, a new row is created in grid view there by retaining the data field in old rows but my problem is whenever I click on save button, at that time data of first row is not retried but I can get the data that is filled in second row and onwards. I have saved my data table in session and again retrieving it after each post back.
I'm trying to execute a query and display the result in grid view.Its working well...
However,I wish to display some simple text like"No tuples selected" making gridview visible to false if there are no rows selected for that query executed.Is there a way to do that?
I try to use the ADO.net to retrive the basic data in details view or gride view of logged In person using 3-tire architecher. I don't want to use LINQ.

how to detect grid view empty cell ? I need it for highlighting. So I made a css
.RedColored { background: FF0000; [code]....
and trying to appear it to empty GV cells this way :
protected virtual GridView1_RowDataBound (_sender : object, e : System.Web.UI.WebControls.GridViewRowEventArgs) : void [code]...but my it doesn't appears to empty cells , even I've tried Text=="" , Cell[i]==null, Cell[i].ToString()=="" and nothing helped.
But !!! It even doesn't helped , it works without WHEN, but when (if) can not find empty cells :P Finally : solved with this code :` e.Row.Cells[0].CssClass = "wide";

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:
i need to retrieve the value entered in the textbox of each row and its corresponding Billno in the cs page i use a button and i retrieve the data in the button click event method. i have used several options like "foreach (GridViewRow row in grdcstomers.Rows)" and storing the gridview values in an array list but i am unable to retrieve the cell values or the textbox values.
I have this gridview made.But it gets populated with columns, column names and template fields dynamically. The template field tht I am using throught the field in each colum is a textbox. The user when loads this page sees a gridview with texboxes in all the columns. I need to be able to retrieve the data entered by the user in the textboxes on a button click.
public class GridViewTemplate : ITemplate { private DataControlRowType templateType; private string columnName; public GridViewTemplate(DataControlRowType type, string colName) { templateType = type; columnName = colName; public void InstantiateIn(System.Web.UI.Control container) { switch (templateType) [code]...
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.
I have a grid view which displays some values. now i have to calculate row wise sum of those values for each row and then display against them.i tried this code but i am getting error as Input String Was not in Correct Format.
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); } }
I have a vb.net page that has a editable detailsview. When a user wants to erase the data for a field, they highlight the data, and delete/backspace over it, and click update. However, the original data is still saved. If they are replacing the current data with new data, that works fine and updates/saves correctly. This problem only happens when the current data needs to be removed.
i'm tring to search my table according to id number or the case number then view it in a gridviewbut it work for the first time then after it stop for error
