I have a rather large formview that asks for a variety of input values (physical totals vs pos report totals). I have created vb code to calculate the differences and subtotals of various types prior to inserting the data so people can check for entry errors.
Its a closing reconciliation form. Here's the problem: If they forget to enter 0 in a field that doesn't have any totals, a big ugly error message displays. I would like to avoid this. I can tell them until I am blue in the face to remember to enter 0 and not leave any blank fields, but realistically its going to happen and I need to handle it in the programming.
I have been struggling to either default the values to zero to start with, replace a null textbox with 0 before the calculate runs...but I can't get anything to really work. What is the best way to handle this?
Here is the aspx page:
[Code]....
And the code behind page with working "Calculate" as long as fields are not left blank (I took out all the test code that made it not work at all)
[Code]....
Finally, the error message I am getting is the following:
[Code]....
I can't seem to find the right combination of programming to account for the "" string to be 0 so that it will add or subtract values in my calculate. I have my sql table setup with default values of 0 so if a field is left blank it will be entered into the database as 0 and not null. It is really just for my inserting of a reconciliation and the running of Calculate Totals to double check their work prior to inserting into the database.
am designing report using gridview in which i want drill down report, i.e. when i click a cell of gridview which contains value from the database. i want a new gridview to be populated with detailed report, which should be generated by passing some values from parent gridview.
i have written some code for the same,but in the code the event is not getting fired.
code is:
in gridview rowdatabound protected void gvHdr_RowDataBound(object sender, GridViewRowEventArgs e)
i am new to asp.net,my aspx page has a datalist which is databound with a imagebutton and two labels in it,when i click the any imagebutton a pop up details page should be opened,in that opened pop up details page the related lablels text should be appeared.
I try to make button inside datalist to be invisble based on a column value from database. I am able to read the column data but i cant find solution to make the button invisible. Below is my code behind:-
We have a Datalist in which we have some data. Out of the 6 columns present in the datalist one of them is the primary key. Each row in the datalist has a "plus" button that will expand in the same window and display other data related to the primary key(in the same row)other than the 6 columns data that is displayed.
What I want to achieve is that on the button click, the primary key related to that particular row of Datalist should be fetched into a variable(whose button control is clicked). How to accomplish this? I am not able to find a solution as to when I click one of the buttons in a row, the particular primary key for that specific row should be attained so that I can call another function and hence retrieve the other data needed.
need that when the edit is clicked the update/cancel appear. user types the update and when press the ENTER key the update is made.How to set the update link button as default.
I have a datalist and the following link button within the datalist:
[Code]....
I would like to post to a new page and then capture the value from the link button (commandArgument). It appears from other threads I've seen that you have to rebind the datalist in order for the ItemCommand event to fire...is this true? I'd hate to make another DB call to bind my datalist just to make an event fire.
I have a datalist inside of an updatePanel. Within the datalist, for each item I have a linkbutton that when clicked I would like to fire the OnDeleteCommand of the datalist so that I can delete the record.
Problem is that I can never get the event to fire, it simply does a postback and then does not fire the event specified inthe "OnDeleteCommand" argument of the datalist control.
I've read many postings with similar entries, but nothing has worked.
I've got a multiline textbox inside the ItemTemplate of my Datalist, which is set to visible=false.I've got a button right above it, with the click of that button, all I want to do is make it visibleI've tried xtNewNote.visible=truethe ID of the textbox has a blue squiggly under it and I'm told that 'txtNewNote is not declared'and I've tried Dim txtNote As TextBox = CType(dlProject.FindControl("txtNewNote"), TextBox) txtNote.visible=trueHere, I just get an object not found when it gets to the second line
I put it down for a few weeks to work on other things, but started working on it again because I need to get it to work.
Anyway, I figured if I wanted to put a button in a datalist all I had to do was:
[Code]....
And then in code behind:
protected void datalist1_ItemCommand(object source, DataListCommandEventArgs e) { if (e.CommandName == "submit") { // code here } }
This is what everyone else says to do when I search google. I put a break on the event but the event never fires. Does it matter if I am using VS 2010 and .net 4.0?
i need to know how to use controls like image button and labels in datalist control,and how to use imagebutton click event which is in datalist control.
I need to change this label to a link that will cause C# code behind to:
tbxCG_ID.Text = Eval("CG_ID") and then call this: protected void ListBox1_SelectedValueChanged(object sender, EventArgs e)
I keep creating a DataList1_SelectedIndex_Changed event created when I double click the label or a link button. What is the code needed? I can see the Eval("CG_ID") value with the label but I don't know how to get it into tbxCG_ID.Text and fire the ListBox1 event.
i'm writing a button which need to open a new window and sending binded data as query string:
[Code]....
here is the open_win function:
[Code]....
But the url created is ".../Report.aspx?type=comment&id=undefined", the queryString["id"] is not defined. In the calling page source html, comment_id has value.
[Code]....
How can i set the variable value of "comment_id" in button onclick, to call the javascript open_win() function ? the comment_id cannot known util runtime, it get value from datasource.
I would like to hide a submit button if a DataList is empty. I don't really know the code. If you submit an answer please show me the code also. I have to do it in VB.Net. I googled and found the following code that I place in the code behind under the Page load event.
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load Dim dv As DataList dv = SqlDataSource3.[Select](DataSourceSelectArguments.Empty)
I have following datalist ,to display employee id, name, email ..... datalist have column with link button text " Get Details" and fontcolor "black" , onmouseover of the particular row i want change the color of linkbutton or the image of linkbutton ..
