Gridview Textbox Value Change

Posted By:      Posted Date: September 10, 2010    Points: 0   Category :ASP.Net
Hi,In my gridview i have productName(Dropdownlist),Description, Quantity, Price,Total and out side gridview i have textboxes like total, tax, discount and GrandTotal. When i select the product it will bind the price and description.  I will enter Quantity value in the quantity column then it will calculate with the price and display the total in the total column.  Where the total column is readonly when the total displayed it will reflect to Total adn grand total textboxes wich is outside of the gridview.  I am able to calculate the total but i am not able to bind the changed value to those text boxes.  when more than one products then it will calculate sum of total column and bind to the total, grand total textboxes.  How can get the total please advise me.Thanks & Regards,Jeevan.

Textbox Editable GridView in ASP.NET

This article describes how I made a fully editable gridview in C# using ASP.NET 2. The idea is that the GridView looks and works like an Excel spreadsheet. You see all the cells in the table, and you can edit any of the cells you like, and they are automatically updated (i.e. saved to the database). This is very often how people expect data tables to work in web pages, and I've often seen people clicking in vain on un-editable gridview cells, somehow expecting to edit them, and not understanding that they need to click an Edit button at the end of the row.

jquery datepicker not popping up in Gridview Edit Template textbox


I have a gridview that I can't for the life of me get the datepicker calender to pop up for.  I've been using the datepicker for months very successfully for a variety of textboxes on the page and inside of formviews but this is the first time I've tried using with gridview.  I didn't expect any issues however can't seem to find anything to work.  I have searched the forums for 2 days and attempted any suggestions found within the solutions to no avail.  I've tried using the CSS to link the datepicker but everything stopped working when I changed the code and my page which uses a css style already got all distorted looking.  Please help!

Here is my gridview (only included a part b/c it is large and am only having problem with the datepicker for the date completed text box)

<asp:GridView ID="GridViewCompleted" runat="server" AllowPaging="True" AllowSorting="True"
        AutoGenerateColumns="False" BackColor="#CCCCCC" BorderColor="#999999" BorderStyle="Solid"
        BorderWidth="3px" CellPadding="4" DataKeyNames="job_id" DataSourceID="SourceJobProjectCompleted"
        ForeColor="Black" CellSpacing="2">

Changing a textbox's readonly property right before update on a gridview


I have a gridview with a date field. I don't want the user to be able to type in their own date and mess up the format so I made the property readonly. That date is then set by a point and click interface. This is all working fine but when the user clicks update this field doesn't update because it's readonly. If i turn readonly off it works so is there a way to turn off the readonly property right before submit?

Value into Textbox of GridView Edit

Hi there, I am not sure this can be done, and if not I am looking for an alternative. Before I start I am using VB.Net and ASP.Net.What I would like to do, is when the edit button is pressed on a Gridview row, I want the TextBox under the ClockOut column, to automatically have the selected value of a dropdown list at the top of the page. Basically so a list of users times will come up in the grid view, and as a fast way to insert a clock out time, the user will have to change the drop down list at the top of the ASP.Net page to the clock out time they want, then when pressing Edit on the row, the time from the Dropdown list will be in the ClockOut textbox, and pressing update will post this. Any help will be great! Thanks, Hope it can be done.

gridview filtering using a codebehind (textbox + search button)

i am trying to replicate the following sequence: input text into text box > press search button > search a database using LIKE operator > display using a gridview or listview. this sequence is fairly easy to do using the drag and drop then sqldatasource options, but i am trying to do the same result using a codebehind.  here is my code:   ____________________________________________________________________________________________________________ SqlConnection myConn; myConn = new SqlConnection(@"Data Source=.\SQLEXPRESS; AttachDbFilename=|DataDirectory|\projectDB.mdf; Integrated Security=True;User Instance=True"); myConn.Open(); string strSQL; strSQL = "SELECT * FROM Message";       //strSQL = "SELECT * FROM Message WHERE Message LIKE '" + txtSearch.Text + "'"; SqlDataAdapter da = new SqlDataAdapter(strSQL, myConn); DataSet ds = new DataSet(); da.Fill(ds, "Message"); GridView1.DataSource = ds; GridView1.DataBind(); myConn.Close(); _____________________________________________________________________________________________________________  now, if I use this code inside a page_load event, it does work. if I put it inside a button_click event i get nothing. i am mystified by this.. any help? why can't i use a button to display my gridview1 when i'm using a code behind.  

Cannot change value of pre-populated textbox in web part

I have a user control inside a web part. I am pre-populating a textbox in the Page_Load event in the code behind of the user control. The value I am pre-populating is a value the user previously entered. The value is pulled from a sharepoint list. We want the user to be able to change this value if they need to. No matter how many times I change the value in this field, it keeps the pre-populated value. It will not save the new value back to the list. The list item is being saved, but only with the pre-populated value. If I remove the line of code that pre-populates the textbox from the page_load event, then I can change the field without issue. Since I have little experience with using user controls, I am not sure what I am doing wrong. Should I be pre-populating this field in another event?  

Alert popup on Gridview Textbox Click

Hi,I am trying to make a Javascript Alert appear when someone clicks on a textbox that is part of a Gridview. the textbox is an Item template and I have an onclick="NotePopup()" in the TextBox properties. I am having trouble grabbing the correct ID of the text box, because it is nested inside a gridview. I have been looking around on Google for a solution but none of the responses are working for me.  The gridview will have multiple rows, so each textbox that could potentially be clicked will have a different ID, is there any way to pass the correct ID to the Javascript, or have the Javascript function grab the correct ID?I did use var Control = '<%= GridView1.ClientID %>';then cut and paste the ID from ViewSource of a textbox and append it to the Control Variable,  to test out the popup and it does workThanks for your helpChris

How to disable fields in a GridView when you change the listbox options?

 Hi all I am trying to apply the same logic I applied to a FormView. Here is what I do:I have a DropDownListBox as one of my FormView fields and when I choose a specific option the fields inside my FormView are enabled/disabled according to the options chosen. Well I havent been able to apply that concept to a GridView. Here is my code to the FormView:protected void ItemFormView_DataBound(object sender, EventArgs e) { DropDownList ddlConfigType = ItemFormView.FindControl("ddlConfigTypes") as DropDownList; if (ddlConfigType != null) { if (ItemFormView.CurrentMode == FormViewMode.Edit) { DisableNAFields_EditMode(ddlConfigType.SelectedItem.Text); } } }private void DisableNAFields_EditMode(string configType) { TextBox txtboxScope = ItemFormView.FindControl("txtboxScope") as TextBox; if (configType == "registry") { txtboxScope.Enabled = false; } } Is there a GridView mode enumeration? How do I achieve the same goal? Thank you
