In my repeater I have a float number that is shortened to a one decimal number (like 1,2 or 4,5 etc). It looks like this:

I have a strange problem with some float values that I pass to an Insert Query.
Example : If I pass in float value "1.4", the value stored in the Database is "1.399999976158141". The DataColumn is of type float.
I pass the float values as parameters to the query using "AddwithValue".
Im using Entity framework with POCO entity generator template + SQL Server. I have mapping to stored procedure that takes two floats as input.
After executing function from code with two doubles as parameters: 1.23 and 4.56, SQL Profiler shows:
exec storedProcedureName @arg1 = 1,23, @arg2= 4,56
This is causing an error because it looks like that stored procedure takes 4 arguments, but it should take only two and there should be dots insted of commas in these floats.

is a way of proofing a stored procedure in terms of the datetime localisation. For example, in the C# we may use the web.config or machine.config to set the application's localised date settings:
<pre>globalization uiCulture="en" culture="en-GB"></pre>
This helps when we do a date comparison in a static class of ours to return a certain rating factor. Is there an equivalent way of us checking whether or not the date we pass into the stored procedure is in e.g. UK format and will be compared against our dates in the UK format too? We have 2 datetime columns, DateEffectiveFrom and DateEffectiveTo in our table and we use those dates to compare with the date passed in to return the relevant data.
i am not getting the output. I can able to display the image using generic handler.What i need is to display without using generic handler.

When i use column name instead of @searchBy which comes from value selected from a ddropdownlist i get the desired result . There seems to be a problem with format of @searchBy and i get a blank page.
protected void btnSearch_Click(object sender, EventArgs e)
{
string constring = ConfigurationManager.AppSettings.Get("con").ToString();
SqlConnection conn = new SqlConnection(constring);
conn.Open();
SqlCommand cmdSP = new SqlCommand("spSearchCombo", conn);
cmdSP.CommandType=CommandType.StoredProcedure;
cmdSP.Parameters.Add(new SqlParameter("@searchBy",SqlDbType.NVarChar,50));
cmdSP.Parameters["@searchBy"].Value=ddlSearchBy.SelectedValue.ToString();
cmdSP.Parameters.Add(new SqlParameter("@searchKey", SqlDbType.NVarChar, 50));
cmdSP.Parameters["@searchKey"].Value=txtSearch.Text.Trim();
SqlDataAdapter da=new SqlDataAdapter(cmdSP);
DataSet ds=new DataSet();
da.Fill(ds);
this.dgv1.DataSource=ds.Tables[0].DefaultView;

I have a text field that users enter information into a database (SQL Server). They are entering as little as a few sentances to multiple paragraphs. I can successfully display the data on my webpage, but the text field is not formatted very nicely. The output is all smashed together like one big paragraph. Ironically, when I also display the text as a tool tip it outputs as multiple paragraphs like it was entered. How can I format the output in the datalist to create a more readable text field? My datalist field is as follows:
<asp:Label id="WebDescriptionLabel" runat="server" Text='<%# Eval("WebDescription") %>' ForeColor="Brown" />
When data comes more than 30 Rows in Grid then the Excel goes in different format.There is parsian/Urdu Font in Grid data.
