Data Controls :: Add Items In DataGrid In Text Change Event?
Nov 13, 2013
I am dynamically bind the textbox in the data grid and in the text box change event i need to add the numbers in all the text box and show in the separate label.
I am using the text box change event and post back to true, I can able to calculate the result but the problem is that on text change itself i need to calculate and show the result, but in my case, when i move the focus from the that text box, the results calculated and focus get lost.
Kindly, see the following image. This is my Gridview with separate paging on the top right of the image. The arrows are Image buttons and the right text box is read only.[URL]
I run my page for the first time everything runs perfect. I move to other pages of the grid still perfect. Then i move to other aspx page and then come back. The page loads perfect with the old page number there still perfect. Now if i press any image button then the text change event fires which should not fire.
Note: i need the text change event as i user randomly enters something in the text box then i have to handle that.
Example:
When i return from the other aspx page then the value in the Page Number text box is lets say 4. Then i press the Back image button and a post back happens. The Value in Text box is still the same 4. Then y the event is firing ???
I am not understanding that why this event is firing. On the page load, i retrieve the values from hash table (The hash table is stored in session in base page) and from the hash table i get the pageNo and assign it to the page No text box.
Here, is my one of the image button event. (Remaining image button events are almost same)

My page load Code: Note: PageUniqueIdr = PageUniqueId retrieved from the QueryString.
I have a series of textboxes on a FormView. There is a textbox for entering a percent for a deposit amount and next to that a corresponding textbox for entering a dollar value for a deposit amount. There are 3 sets of these.
If a user changes a percent textbox, I update the dollar value textbox based on the percent times the project's total cost. If a user changes the dollar value textbox, the percent textbox gets updated as a percent of that dollar amount divided by the project's total cost.
I have the percent textboxes formatted as "{0:0%}" and the dollar value textboxes as "{0:C}".
When a user types into the textbox, the formatting goes away and we get raw numbers but I don't want those raw numbers to remain as such after they tab or click out of the field. I added a TextChanged event to reset the formatting. This works fine on reformatting the percent textbox but the currency one remains as just a raw numeric value.
Here is the markup (ignore the lack of validation for numeric input only...it will be added):
I have one Datagrid with Footer. Footer Row Contains Input fields with one Button to add New Values. I have button click event but not getting fires. my code follows:
I have a DataGrid with a template where i have a counter. When i add items to the dataGrid and want to change the ammount for a specific item, all the rows in the datagrid changes. How can i only change one item in the datagrid?
page here in asp.net3.5 with C# i m using a datagrid and have Control textbox in it and now oi want to use the textchanged event of this text box so i can perform opertaion on every text box
I have a datagrid that has photos and a description of the individual in the photo. I have a procedure that works and if I execute it with the correct parameters it changes the rows in the table. I have a datagrid with two image buttons, MoveUp and MoveDown. I just want to be able to reorder the photos when needed.
In my proc called "MoveMember" I have these parameters that are passed in. The column that gets swapped in my table is the "OrderBy" column, they are just numeric numbers 1,2,3,4 etc.
I am placing a dropdown list in the footer of a DataGrid like this:
[Code]....
In my code behind file, in the myDDL_OnLoad event handler, I call to the database, populate a SqlDataReader, and set the DDL's datasource to that datareader. I define what data columns should be used for the DataValueField and DataTextField of the dropdownlist. Then I call the DropDownList's DataBind() method. Everything works without error. But, when the dropdownlist is displayed, it has blank lines in it.
By that, I mean if 8 records are loaded into the dropdownlist, it will expand to a size appropriate for 8 rows but, it will be empty. there is no text in it.
Has anyone seen this type of behavior before? This dropdownlist is in the footer of a dynamically loaded ajax update panel so, it is difficult to see the source code to see what values are in the html element rendered to represent the dropdown.
I had called the data from query to data table and now i have a gridview in which i am using one datalist and 2 text boxes and and reming coloumns are bounded iahve to assiaign them values which datatable have either null or any value.
I have a textbox with autopostback=true and a button to save the data in the form. Functionality works fine when entering a value in the textbox, tabbing out of the textbox and clicking on the save button. But issue comes up when entering a value in the textbox and directly clicking on the save button without tabbing out of the text box. In the second scenario, only textchanged event fires and save click event dosen't fire. What I was expecting was after exection of textchanged event, save click event should also fire. But this is not happening.
I'm using code to convert items in a Datagrid row from UPPERCASE to Title Case. It works good, but the problem is if it comes across a hyperlink field, it will put in a blank value. Not sure why its doing this, but here is the code below. Wondered if any one has came across this problem and managed to solve it?

I'm trying to change one section in code from DataGrid format to GridView format. The reasoning is that the sample application that was displayed was using a DataGrid even though it should have been using a Gridview for 2.0 and above. Most of it shows up without an error except one line in 3 lines which are pretty much the same. I bolded them and just want to know how do I re-write them for the Gridview?

i want to display a multiline text in a datagrid i insert the text in a textbox outside the datagrid.
the textbox wraps the text if it doesnt fit to the textbox length.then i push a button and insert that text in a database. then i want to display this text in a datagrid.i use two options in a label or in a textbox in a templatecolumn but with the textbox <asp:textbox ID="textbox1" runat="server" style="overflow:hidden" Font-Size="15px" BackColor="#FFFFC0" TextMode="multiline" Width="750px" Wrap="true" borderstyle="None" BorderWidth="0" Text='<%# Databinder.Eval(Container.Dataitem,"text_caption") %>'></asp:textbox>
i receive only the first two lines
and with the label <asp:Label ID="Label112" runat="server" BorderStyle="None" Width="750px" BorderWidth="0" Text=' <%# Databinder.Eval(Container.Dataitem,"text_caption") .ToString.Replace(chr(13),"<br />") & "<br/>" & "<br/>" %>' ></asp:Label>
if the text is too big without an enter(that text wraps in the outside inserting textbox) then the datagrid width becomes too big although the text is diplayed normal with new lines so in the datagrid i have much space without characters the textbox that i use to insert new text is here <asp:TextBox D="tbox_text_caption" runat="server" Height="232px" Style="left: 400px; position: absolute; top: 8px" MaxLength="750" TextMode="MultiLine" Width="752px" Wrap="true" TabIndex="5" BackColor="#FFE0C0"></asp:TextBox>
I've tried many different ways to try to get the selectedIndexChange to work for my dropdownlist. It doesn't seem to work, when I debug, I can see that the page is doing a PostBack but the method that suppose to be taking care of the select index change doesn't seems to be fired. I notice that there is no "handles" in many post so I was just wondering why it doesn't have it?On postBack I didn't rebuild the list so the selectedIndexChange value shouldn't reset to 0.Sub ddlAccess_SelectedIndexChanged(ByVal sender As Object, ByVal e As EventArgs) ''handles ......?" ...
